Good to know your motor looked similar to this. I appreciate all the feedback and will update the thread as the engine gets reassembled.

Yes heads were rebuilt with new guides, seals, new valves, ported, springs, retainers, the works. I was reading another thread on here after doing some searching about gapless piston rings. As these rings can increase manifold vacuum due to the seal being so good in the bore vs a conventional...

Here are some pics of the situation lol. Hopefully they upload. Yes that’s liquid oil in the exhaust manifold.

Ya I spoke with total seal yesterday and got the same sort of push of these rings are great blah blah. The guy I spoke with even said he had them in his v10 triton modular, I didn't really care lol. Did you or juiced 4.6 try different kinds of cylinder finishes and checking them with a...

Thanks for the replies. I have done a lot of reading and seems this is my issue. Has oil on my intake valves and figured it was bad valve stem seals or excessive guide to stem clearance but the heads are brand new and reworked, also has viton seals . I talked to a gentlemen at Ross racing...

I’m having these same issues and have a gap less top but I have a Napier 2nd which from the GM research you said fixed the oil control issue. I’d be curious of your thoughts on this. Smokes like a train at idle. Under throttle it’s no issues. Literally all the same issues.

Update: Talked with Ron at Fox Lake and although he doesn't work on these heads anymore he highly recommended I speak with Kris Starnes. Got with Kris and sent some videos to him I had of the play in my valve stems while valves are closed. They're bad so I'm sending them off to Kris for full...

Screwed up that last reply, not sure how to delete it. Anyway... No PCV correct. Ya I should have tried it prior to dropping the motor out but I personally don't think it would have made any difference. There are no vacuum lines connected to the crankcase where oil could enter the engine, this...

I'm 100% with you and I was trying to tell my boss this personally. There is no blow by whatsoever at idle, zero. I'm gonna tear into it this weekend get a better analysis on the heads. I'll keep you all updated. Keep the thoughts and situations coming.

It's not the turbo. Downpipe, turbine wheel and housing are bone dry. Cold side piping and intake manifold are also bone dry. Motor is out of the car so I cannot run it anymore. All spark plugs exhibited oil on spark plug threads. I haven't had much time to look at it since I got it out...

Oil control ring on these pistons does not intersect with the piston pin bore. Also ring flutter in my opinion would be related to sealing of the rings and they are sealing very well. Started another cylinder leak down last night didn't finish since Astros are in the world series, but i got...

No the guide and stem would see pressure in this test. Imagine pressurizing the intake runner. That's pretty much what I did. I have a vacuum pump but didn't have the fittings to hook it up. Should probably do that. You'd think it work both ways though. Correct, smokes at idle with high vacuum...

I might also add that the first time when I had done the leak down and compression test I created a metal plate that goes over one intake runner port at a time with a threaded quick connect tapped into it and also drilled holes for the bolting locations at the head. Used the stock gasket and...

Ya that is the plan for sure. I've though the clearance there is maybe too much and its causing movement in the valve stem seal causing oil to get by. That would suck. Last motor is a story bro, I won't even go there lol. Washed the rings out in it due to stock pcm issues, has Holley dominator...
