So as the title says, I get this really annoying rattle in my engine bay right at 3200RPM and after. Ive searched but haven't had much luck. thanks in advance.

could be loose nuts/washers on your exhaust manifold. the mani-to-turbo flange also is a common place for nuts to "back out" if you didn't use the locking tabs AND if you didn't bolt your downpipe to your tranny.

also, my brakelines used to tap eachother in the engine bay which is annoying as shit. do you still have any heat shields on your exhaust mani? heatshields always rattle.

but really, just get in the bay and just move stuff around, ya never know you might get lucky.

Yeah I already removed my heatshield, which did slightly rattle. Heres a quick youtube video I just made so you can here the annoying rattle. You can here the rattle at around 8 seconds and then again at 14 seconds into the video.

lol wait a minute, so what the fuck was i looking at?!?

ignore me

but yeah i just listened to the right vid..holy shit mang, your engine sounds like a motorboat. sounds like you have a beastly exhaust leak. CAREFULLY put your hands near your exhaust to feel for the leak. where the turbo connects to the mani and where the turbo connects to the elbow.

Lol, My bad. Thanks for fixing that for me downshift. Im just in hurry cause im about to go to class and take a test pretty soon.

180drft · 02-27-2008, 12:13 PM

So it looks i do have an exhaust leak due to a blown gasket. Would this be the exhaust manifold turbo inlet gasket? http://phase2motorsports.stores.yaho...etexman1.html? Just making sure. Thanks alot Unicoldaron.

Big Bronze Rim · 02-27-2008, 04:14 PM

Yes, that is the correct gasket. A 300zx TT gasket will work as well if you want to source it from the local dealer.

Cool, Thanks
