I figured that this question would apply to all V8's. I have a 95 Chevy 2500 with a 350 with high miles on it, unsure exactly how many. It has a huge appetite for oil, like 1 quart every couple hundred miles. I changed the pcv valve for kicks but it still burns it. I know it isn't leaking out, it doesn't puff blue when first started or when you get on it. But oil does puddle on the intake below(next to) the thottle body near the two middle intake bolts. I was thinking that the intake manifold gaskets are bad, but wanted to see if anyone else had an idea before I tore it all apart. It also fouls (blackens) the oil really fast when I change it. The trucks seems to have plenty of power though. Thanks for any help. Sidenote, Getting a new motor for the Mustang.
