oil coming out of the exhaust tips?
Hey guys, a buddie of mine just bought a head,cam,blower car from a guy on here. We went and picked it up Friday. The car is supposed to have a forged bottom end also. The car was throwing several codes, misfiring in the cylinders,egr, rear 02 codes and something for the air.Not sure what else but anyway the car drove fine and all so he knocked some money off the price off the car and we brought it home. We get it home and he was driving it today and said it kinda back fired a little. When he got it home there was oil dripping out of the tailpipes. What the hell could it be? I hope it didnt blow up. Thanks for the help. Charles

im one of this guys buddies that went to pic up the car....well i just left his house and this is not condensation and no drips....freakin oil is pouring out of the tailpipes, and every slip fit on the exhaust is leaking considerable amounts of oil... something is definately not right...that should help you guys out a little better...

Just some quick food for thought if the exhaust system is new, their is a grease/oil that goes inside the tube for when they mandrel bend it. Also if its leaking from the slip joints then that slip join needs to be tightened becuase there is an exhaust leak there. With the amount of oil that you say is in the system it seems to me that the car should of used a fair bit of oil by now, what does the dipstick show? I would take the exhaust system off from what I assume are headers and not the stock exhaust and see how much oil/smoke comes out of them.

We installed new Patriot heads, car started blowing oil, (16000 mi. on car) valve seals were teflon (white in color), Patriot sent us new GM replacements, we installed them, no more smoke. Check your valve stem seals.

Whats up guys? Thanks for trying to figure out what is going wrong with the car. I'm planning on taking it down to Jeff Creech this week or next hopefully and having him seeing what is wrong with the engine. The engine has MTI 2E heads, C1 Hammercam, P1SC on the 7-8 lbs. pulley, weisco pistons, and has been bored to a 347. Maybe this can help you guys out a little bit. I'm planning on swapping the heads out for some 6.0L heads and putting a decent blower cam in it. I guess I'll have to see what is wrong with it first though. Thanks for your insight guys and I'll keep you posted.

If I'm not mistaken, If your valve seals are shot It will smoke real bad on start up(oil from heads draining into cyl.) Then the smoke will lighten up a bit . I'm not too sure how much oil in LS1 top end there is but in Traditional Chevy 350's that's what I 've seen. Could be A Deck problem or the Rings ? I Wish You Luck.
