Car Forum / Pontiac / Pontiac Fiero / July 2005Oil Leak 2,8l
Hello, i have a 86 Fiero with a 2.8l engine. Its leaking more oil everyday, i can`t find the leak, the oil comes from high up in the engine. I can hear my vavles making more noise also, i stopped driving in it!!! Can anyone tell me if this is a common problem or where i should check for a leak. Thnx Martin Vos martinvosje@wanadoo.nl > Hello, > [quoted text clipped - 9 lines] > > martinvosje@wanadoo.nl The O-ring seal on the distributor. Classic for this engine. > Hello, > [quoted text clipped - 9 lines] > > martinvosje@wanadoo.nl The only place for oil to leak under pressure up high on the engine is the distributor O-ring. A new O-ring from GM or http://www.rodneydickman.com is only a few dollars, and they use a special long-lasting fluoroelastomer. Do not use the O-ring from the auto parts store as they are typically Buna-N which will fail quickly in this application. Here's a picture of the O-ring in question: http://web2.airmail.net/jsavage1/formula/distributor_oring.jpg JazzMan  Signature********************************************************** Please reply to jsavage"at"airmail.net.

I`ll replace the o-ring. Thanx Martin Vos check the timing chain cover... These are notorious for wearing a tiny hole in them from the tight specs they had to have. I have fixed about a half dozen of the same thing... mysterious oil loss. -Arlie Bright www.fierostripes.com > Hello, > [quoted text clipped - 9 lines] > > martinvosje@wanadoo.nl A common leak is at the distributor shaft O-ring. Oil goes all over the engine when it leaks at this point. What is important is how much oil is leaking., in terms of whether oil is seeping or dripping. If it is a very slow seep of oil such that say a quarter of a quart of oil leaks between changes, it may not be a problem that even needs to be addressesed. K.E.R. > check the timing chain cover...
