I have a C33 Laurel with an RB20DET, and the car runs normally, but there's been an issue bugging me since I bought it. Whenever I go full throttle(or close to full throttle) and start making boost, there's a noticeable burning smell coming from the engine bay. There isn't any smoke, and the turbo spools up just fine. I've checked the oil level often, and over the 4 or so months that I've owned it, it hasn't dropped noticeably at all. Is this likely a blow-by issue? It does have a pod filter, straight pipe exhaust, and external wastegate. I would think that a bad turbo would consume a lot more oil.

Burning smell & Error codes Hi boys, new to the forum. I have a question and I know there's been posts about this before but I couldn't find anything related to my issue what so ever. Friday just passed on the way home from work I could notice a slight burning smell of rubber or plastic. At first I didn't worry too much because t could've been from one of the cars around me as it was peak hour traffic. However, the smell followed the whole way home. Since then I am avoiding driving it until Tuesday week. The smell will only start after about 5 minutes of driving, I wouldn't say it's an electronical problem as surely something would've happened already and I would've noticed. Just assuming. I couldn't see a plastic bag stuck to my exhaust but I didn't get a proper look as my car is too low. The smell more so comes from the driver side but I can't pin where it's coming from and when I look and smell through the engine bay I can barely smell where it is. Two weeks prior, I had some high flow cats installed so I'm not sure if that might possibly be part of the issue either. If anyone has any rough idea or have experienced that issue it would be good to know. Im booked in with Hi Power Racing next week, I might have to wait until then. Thanks

Bad piston rings or damaged cylinder walls? Recently, I opened a discussion on my excessive oil burning that my rb25det does and thanks to the help of many enthusiasts we concluded that it is bad piston rings or a damaged cylinder wall... or can it be both? Engine had a full upgraded rebuilt 6 months ago with it being bored over .020 over. It has been driven 1000 miles or 1609 kilometers since I have compression tested all my cylinders and it showed a psi of 50-70psi. When I did a wet test it shot up to 120-135psi My rb25det has a 1.5 cosworth head gasket so compression will be lower than normal My hopeful prediction is that the piston rings have seized, been installed improperly, or the rings are worn out. The reason why I don't believe its damaged cylinder walls is because every cylinder shows the same sign of compression loss and piston rings go out together. Cylinder walls are unlikely to all be damaged at the same time What do you guys think?
