Well today I was underneath my truck changing my fuel filter when I got to looking and dag blast it all I found both oil and antifreeze on the underneath side of my truck!! Now i dont mean a whole heck of a lot, especially with the oil..the antifreeze is a little worse. So I get to lookin and sure as heck my drivers side valve cover looks to be a little nasty in the back..Im thinkin that gasket must be gone. Now the where the antifreeze is coming from...thats my mystery. I looked all around, thermostat, hoses, drain plug, freeze plugs..I looked everywhere I knew of and I couldn't find anything. The only think I saw that looked wierd was almost some stain marks on my passenger side cylinder head and like a drop or so on the rear of the side of the passenger side cylinder head. Every so often I have to add to the resevoir but that is all. What the heck could this leak be, and what could have caused it? I swear I aint in the mood for either all this work, or all this money..

 

I have seen the intakes on the ohv leak pretty often... they can leak oil and antifreeze.. more than likely, the antifreeze is seeping out of the intake gasket and running down the head. seen it happen numerous times.

 

on 99% of all 3100 motores also... in pontiacs, oldsmobiles, etc...

 

thats a totally different story.... all gm's mark their territory. doesnt matter if its green, orange, red, brown, or clear, a gm is going to leave its mark...

 

Okay well now that could be tons better, thats my problem is that I cant really see anything well enough. Thanks for letting me know that Nick I was freakin out. I mean intake isn't any small thing for me either but still not as bad as a cylinder head gasket.

 

the 3.0 dohc every one that has some miles on it is leaking oil my truck the valve cover gaskets are stating to leak an it only has 50 miles on it
