**Troubleshooting a Modified Car with Oil Leaks and Diagnostics Issues**

As I work on my recently purchased car, I've encountered several issues that have left me scratching my head. The car has already been involved in a fire, likely due to a fuel-related issue, which has raised concerns about potential leaks and damage to the engine. One of the first things I noticed was a peculiar smell emanating from the fuel tank. When I turned off the engine for an extended period, the smell intensified, making me wonder if there was a leak in the system.

To diagnose the issue, I've been experimenting with UV dye injection, which has revealed some alarming signs. The dye has shown me where the leaks are, and it's clear that something needs to be addressed urgently. The fact that the car has already experienced a fire increases my concern for potential fuel-related issues, and I'm taking extra precautions to ensure everything is properly maintained.

One of the most daunting tasks I've encountered is trying to connect my computer to the car's systems. This involves using a multiplexer, which is a Chinese-made component designed to mimic an OEM part. However, I've hit a roadblock with connecting my computer to the multiplexer via USB. The reason for this issue lies in the fact that the multiplexer is not compatible with my computer's serial port. After trying various drivers and adapters, none have worked, leaving me stumped.

The lack of communication between my computer and the car has made it impossible to reset the airbag light using the system, which is a critical feature for registering the vehicle. With the current setup, I'm unable to drive the car on public roads, which is frustrating considering I've already taken the car out for test drives without connecting any additional parts.

To tackle these issues, I'll be experimenting with different solutions, including finding alternative drivers or adapters that can connect my computer to the multiplexer. Perhaps using a genuine OEM part or seeking the assistance of an expert in automotive electronics will help me overcome this challenge. As someone who's spent countless hours troubleshooting these problems, I'm eager to hear from others who have encountered similar issues and may be able to offer valuable advice.

**Car History and Previous Issues**

The car has already been involved in a fire, which suggests that there might be some underlying fuel-related issues that need attention. When I bought the car from Hoovy, it was clear that there were some previous problems, but the extent of the damage wasn't immediately apparent. As someone who's always been interested in cars and tinkering with them, I've taken it upon myself to investigate the root cause of these issues.

**The Importance of Proper Diagnosis**

As a DIY enthusiast and car owner, I know how critical proper diagnosis is when dealing with complex problems like this. The fact that I've encountered multiple issues, including oil leaks and diagnostics challenges, highlights the need for careful examination and troubleshooting. By taking the time to understand what's going on under the hood, I can address these problems before they become major headaches.

**Solutions and Advice**

To anyone who might be facing similar challenges with their own car or modifications, I would advise being cautious when dealing with complex electrical systems. It's always better to err on the side of caution and seek professional advice when needed. For those looking for solutions to connect their computer to a multiplexer, I recommend exploring alternative drivers or adapters that can address compatibility issues.

By sharing my experiences and seeking advice from others who have encountered similar challenges, we can work together to find innovative solutions and get our beloved cars back on the road in no time.

**The Need for Expertise**

As someone who's spent countless hours trying to diagnose and fix these issues, I've come to realize that sometimes, it's necessary to seek the help of an expert. Whether it's a mechanic or an automotive electronics specialist, having someone with the right knowledge and experience can be invaluable in resolving complex problems.

**Conclusion**

With its unique blend of DIY enthusiasm and technical challenges, my car project has been an exciting adventure. From oil leaks to diagnostic issues, I've encountered a range of problems that have pushed me to learn and adapt. By sharing my experiences and seeking advice from others, we can work together to overcome these obstacles and bring our cars back to their former glory.

"WEBVTTKind: captionsLanguage: enCostigan guys my name is devar and today is gonna be a little bit of a different video you see my 2008 Lamborghini got a spider it's in the homestretch of getting done 100% but I need your help in finding out a few of its issues before I get it done so the first thing I want to take care of is just the saddest saddest dog in the world actually on the car what I'd like to take care of is the oil burning problem now a lot of you have been telling me about the oil issue on the car when I rev up the car and let off there's a plume of smoke that comes out and the reason is not because of the rings or anything in the engine or anything internally it's because of the turbo system everything here is 100% custom and because it's custom I had to figure out a lot of solutions for these problems so if you take a look at this turbo this is actually the one that's leaking if you look down below you can see that the turbo oil drain line right here the drain line usually is supposed to go down and into a pan since these turbos are mounted very very low that has to make a 90-degree turn it goes around the back of the transmission and then it goes back there it splits off into a Y and then goes into the pan but it goes into the pan on the bottom but this is a dry sump system so on the bottom where the oil pump pickup is that's also the drain hole so basically they're suction there and it should be sucking out all the spent oil from the turbo however it's not doing that the oil is actually backing up because I think this angle here it's a little too shallow and it's not allowing the oil to gravity feed as fast as it needs to there is a bit of oil pressure coming in here but it's not too much I know that it's around 40 to 50 psi which is perfectly fine for this turbo it doesn't need any restrictor anything like that these are internally restricted these are BorgWarner efr 83 74 turbos which are dual or maybe even triple ball bearings so they don't actually use that much oil so I have to figure out a solution to fix this problem I don't want this thing burning oil it's it's kind of embarrassing and also it's not very good for the turbo long-term so I figured out a solution which a lot of you guys have told me and that is to put a sump on the bottom of the turbo right here just put a sump where the oil basically gravity feeds it gravity drains rather and then I have a scavenge pump basically sucking up all the oil and putting it back into the tank now the issue that I'm having and the thing I want to address and ask you guys about is whether I can use a oil catch can to use as a sump now I have one of these actually I have two of these I bought two of these and these are just generic catch cans that I got from Amazon and this was about 50 bucks and there's no reason in my mind why this wouldn't work it has 10 aan fittings and those go directly on here I can just have a line going from here to here I can mount them somewhere in this vicinity somewhere like that and then on the bottom I can just have another 10 a and out and then that is where the suction is gonna happen now I just have to cap off one of these because I don't need to use both ports but this is I believe 0.7 liters and this is perfectly fine for draining one turbo and I'm gonna have two of these because I have two turbos so if any of you can tell me if there are any specific issues with this setup that I'm thinking of then let me know because I don't see any this looks exactly like a regular sump that you would use for a low drain oil scavenge system for a turbo so this seems like a really good solution I couldn't find anything that was off the shelf for a turbo I know that the skid factory guys they did use some they have them kind of readily available in Australia and they're just like a little bar that goes over here and they actually bolt right onto the turbo which is a really cool and elegant solution but I don't have first of all I don't have the space for it I think it just hit this pipe and also those just aren't available to me it's I couldn't find them I've been searching for days and days and yeah it's it's really hard to find so I think this is gonna be the solution but I'm gonna wait for your guys's response because this is gonna be the thing that stops this thing from well being an oily mess when I decelerate so these two are gonna go into a line and that is gonna tee off and that is gonna go into here this is the turbo works exa pump and this is supposed to be a really really good pump for scavenging oil from a turbo system supposed to be probably the best pump on the market so that is what I'm gonna use now I'm gonna have to mount that somewhere up in here like right on there's a frame rail over here so I'm gonna have to mount that it's not a problem I am gonna have to take this guy off and give myself a little bit more space and then I'm going to have to drill a hole into the oil tank itself and then use one of these one of these weld on fittings one of these guys right here and then that is the way I'm going to drain back into the oil system now that is a bit of a project so that is what I'm gonna do in the next episode hopefully I'll be done by tomorrow if not then it's just going to be done by Friday it is a everything here is custom so yeah just bear with me here so if any of you have any solutions or know that this is actually a good solution for me then let me know in the comments but on to my next problem the fuel tank so the fuel tank has well I'm not sure if it has a leak or anything like that but the the fuel tank does have a smell coming from it or at least somewhere in the fuel system now it doesn't seem like there's a leak at all it doesn't look like it I've checked every single connector and nothing's been leaking but it smells like fuel vapor and I'm thinking it could be either the charcoal canister or something else so I have figured this out so this is a UV dye that you can use for oil transmission fluid gear oil fuel anything basically just put this dye in there and then use this black light yeah right there you can see that it basically shows you where the leaks are when this dye is injected now one of the things I'm really scared of with this car is the fact that it has already been on fire for a fuel related thing and I just bought a car from hoovy that had a fire for likely a fuel related thing so I'm gonna try to be as cautious as possible and I'm gonna have to diagnose this because if it's something like the charcoal canister and it just has a line that is unplugged then that's totally fine and I can I can deal with that all I have to do is plug it up but keep in mind that this has a non vented fuel cap the cap is well it works just like om the OEM is also non vented but the tank itself is vented so you guys let me know if you've had any issues with cars that have been heavily modified and with fuel smell because it does smell like raw fuel if I turn the car off for any period of time it is very very disconcerting and it does smell a little bit like I have a leak but I can't find anything so you guys let me know what you come up with but our next and final and perhaps biggest problem is this right here this is what's called a multiplexer this is a Chinese multiplexer that is a copy of a I believe it's an act eeeh XS pass through plus and these are what's necessary to connect my computer to my car and right now my computer cannot connect to my car because it can't see the multiplexer now I have the very expensive lera software that is a diagnostic software for that i beginni installed on my computer but it can't communicate with this thing and the reason why is because this is actually it's a USB and it should be a serial and I don't have any serial ports on my computer now you can say oh I can just get a serial 2 USB adapter but that's not what I have to do this is actually a USB plug and I can also not find the drivers I don't I can't find the right drivers I've tried a million a million drivers for this thing and none of them work I can't connect to any car this is supposed to just work off of obd see we have the obd plug right here and it lights up and everything but i can't connect to the computer and this is a big problem because if i can't reset the airbag light using this system then i can't get the car registered and i can't drive the car so it's literally just this problem that's keeping me from actually driving the car on the road otherwise i drive it right now even without the bumper or everything else connected so if anyone has a solution maybe finding a genuine version of this a actia basic xs+ pass through if you have one or know somebody that has one that is a serial and then I can just use a regular serial to USB adapter so I can assign that to com1 the comm port one on my computer I know I'm getting a little bit geeky and jargon here or if you want to do a TeamViewer session or something like that and get this thing working with the correct drivers and you know what you're doing then there is a pretty good paycheck in it for you because I am at my wit's end I really really need to get this going this is the last thing that I need on this car before it starts driving so I this is what I need your help on guys the most hey girl what are you doing good good come on come on come on there you go so honestly I've been trying to fix these issues for the last month or so I mean I'm on Version three of the oil burning issue I'm on version who knows on the computer issue I mean I've been through so many iterations of drivers and I've spent so much time on it that it's just kind of ridiculous right now but the fuel issue hopefully that's not too big of a deal and you guys can let me know in the comments or in the email link down below my email is asked of ours at gmail.com that's probably the best way to communicate with me probably the best way to get me information so I appreciate everybody for watching and I appreciate everybody that's gonna answer the questions that I have and hopefully you guys can help me out and we will get this done together but until next time this is me telling you that on cars like this that have like three things that need to get done before they are awesome beasts with turbocharged engines you guys need to wrench every day see you next time youCostigan guys my name is devar and today is gonna be a little bit of a different video you see my 2008 Lamborghini got a spider it's in the homestretch of
