Ok, I cranked my camaro up today since it hasnt been cranked in more than a week. I let it get warm and did my walk around, looking under the car and everything. I heard a noise, like fluid dripping on the header, so I shut it off. I got to looking a little bit of oil was coming from the # 2 cyl. header tube. I jacked the car up and looking in the header and oil was coming from # 2 cyl. and getting around the end of the collector.

What would cause this to happen? It is a newly built motor and only has one pass down the 1/8th mile. Could it been the rings havent seated yet? What about a valve guide or something?
I will pull the plug and see what it looks like. I may pull the header off to get a good look at # 2 cyl.

Is this something to get worried about?

Thanks, Justin

Oil should not flow out of the exhaust valve.

Do you hear a 'miss" at all?

You already know the next step... Pull the plug and report back.

Ok, I just pulled the plugs and all looked great, except # 2 plug. The # 2 plug has a thin layer of oil on it, not major just enough to coat the plug. The rest are brownish or tan color and no sign of detonation. I'm running Autolite 3924 plugs and pump gas.

So, what is the problem here? I'm thinking it would be the rings, before and thing else, though I may be wrong. I would really like to hear some ideas on this one.

Thanks, Justin

I don't think it is a ring-seating issue if it is only occuring on one cylinder. On a fresh rebuild, it shouldn't be a valve guide problem if the seals were replaced.

If you are not hearing any valve clatter and there is no miss or roughness at idle, your heads and valvetrain are probably fine.

Could it be a poorly sealed intake manifold allowing oil to be sucked from the lifter valley into this one intake runner?

Thanks for the help. I didnt hear any clattering or anything. It is only that one cylinder and the rest are fine. It maybe the intake not sealing right there, it just started happening today. I'll figure it out, taking the intake off isnt nothing, or a head, even though I wouldnt want to.

I think I would do a compression/leak-down test before I did anything else... might save yourself some work....
Did it sneeze or anything when you started it? I have seen a backfire blow intake gaskets out if not torqued properly... and sometimes even when they were torqued correctly....

Just my 2 cents worth....

It hasnt backfired before and my next step is to do a compression test. Hopefully I'll find something out when I do the compression test and get it fixed.

probaly a valve cover leak that u r missing the source of

probaly a valve cover leak that u r missing the source of
dusty he is seeing the oil inside the collector comming from the cylinder #2 tube/ pipe my gess is a prob with cylinder 2 exhust valve guid/seal do a comp test if thats ok id pull that bank v cover check seal go from there....
