I have a 91 z32 n/a. Today I was putting the headers on and had to remove a few things around the motor to get more room when removing/installing the headers. When I removed the air intake pipes from the TBs I notice that there is oil residue sitting on the bottom connections next to the radiator. The oil is dripping from the TBs down. WHAT IS THIS? HOW BAD IS IT? WHAT CAN I DO TO FIX IT? Please help me with instructions if possible, since my budget is really short. Thanks

It sounds like blow by. Is it on both sides? If it's only on one side, it could be a valve guide or valve seal gone ad, but if it's on both sides, it probably means the rings are shot. I hate to be the bearer of bad news.

If anyone else has another idea, please help this guy out.

Yeah it's on both sides. The driver side was only a litle. But the passenger side is the one that is the worst.

I forgot to mentioned the fact that my car is N/A... yeah, not a TT. Who has ever heard about this happening to a N/A? It makes no sence!!!
