this stroker motor and another were built at the exact same time both with the same bore and both had the rings filed to fit the block at a very reputable race engine shop and we were that to witness it being done. the other engine has patriot heads and it has had no issues whatsoever

I would replace valve seals first just because its easy, but if its not that man its Definently a ring issue.

You may want to try and run the PCV to a catch can. I had to do that on my 383 to stop oil consumption.

From the look of the pics, I'm thinking you are seeing a PCV problem. The runners are completely coated with oil. Is the intake coated as well? If so, that is PCV. I don't think it is a seal problem. With GM guides in the heads, I just don't think you could consume that much oil though the guildes even if there weren't seals on the guides. I think I would look at putting a better breathing setup on the car along with a catch can. If you want to change the valve seals on the heads just let me know and I will send you a set of valve seals. However, I honestly don't think that is the problem with the oil comsumption in this case.

Did you read above?


Catch can will be next.

LOL man, you sent me the PM asking for a response. Yes I skimmed through the above. What I posted is my opinion. Whether that is backing up yours or someone else's idea makes no difference to me. If you want me to send you some valve seals to rule that out as well, I have no problem doing that either. Just let me know what you would like and I will make it happen.

put a catch can on it, talk to Tracy at RevXtreme if you want another opinion, he can tell you just as good as anyone why you need a catch can. i don't think valve seals or guides are your problem here....there isn't enough room in the pcv hose to allow the oil vapor to condense, and with it being a stroker, it's just going to push that vapor right on past the pcv valve. you need a catch can (large-volume area) to allow the oil to condense and settle before it can be sucked into the engine.

The car I was talking about from Xtreme Powersports with the bad rings had a catch can on it and there was never any oil in it... It always had oil puddled in the intake, as well as in every runner and on the valves. It would get this bad in a 5-10 minute drive up the road and back. There was never any oil in the catch can though.

Since some of you are so insistant that it is the PCV let me share with you this tid bit of information. When the old PCV hose was taken off, there was "NO" oil in it at all. It was clean. Now, with that being said, tell me how all that oil is getting in my intake runners and puddling on top of my valves?

I ordered valve seals from SDPC a month ago so when we got to the point of pulling the intake to replace the valley cover, I would have them just incase. The valve seals seemed to be seated OK so none were replaced yet.



Jon, thank you for your offer and I will be taking you up on it soon if what we are about to try doesn't work. I really do hope to have this problem resolved very soon. This engine came out of my car on July 5th.

It's clear that you do not fully understand what a catch can does and how they work. Just because you don't see any oil in the stock PCV lines doesn't mean a can will not be beneficial. The post below (post a few before your last) touches the tip of the iceburg on the subject.

Sigforty

I have to agree. I never thought I had a problem until I pulled the manifold off and saw the oil in it. That told me right there that while my hoses were clean the oil was condensing once it made it to the cooler manifold. I added a catch can, and it was collecting significant amounts of oil. I eventually had to just vent my catch can to the air, and not run any pcv lines into the intake tract. That was the only way I eliminated the oil consumption on my stroker.

how was the smell/surface of everything in the engine bay after you let this vent to atmosphere? ive heard of severe cases where the smell is just god aweful, and a nasty film being left on everything in the bay.

There's a little more info on the PCV catch-can setups from Rev Xtreme.

Sigforty

Never really noticed much of a smell. There is no film on anything under the hood. If anything I smell the exhaust from my car more than anything else with the cam and overlap it has.

that's what i was looking for...too lazy to REALLY search though. i just got my RevXtreme can the other day, had it powdercoated SOM....if nothing else, it'll add some nice aesthetic quality to your engine bay...

Catch Can ordered today from Vengeance Racing. 1 day shipping. It will be on the car Thursday afternoon. I'll update accordingly.

I did not build this motor, I did help them do the install. I am the one that will correct what ever the issue is. A ring issue will not cause oil to puddle ontop of all 16 intake and exhaust valves. Pic below

All valves are like this. If you go with the incorrect theory that its the rings than you must also believe that if you dump a gallon of water in you living room floor that it will show up as a puddle on your roof.:think:
I upgraded all of Davids PCV system by removing his intake manifold and installing a LS6 valley cover which improves the CrankCase Ventialation by pulling crankcase pressure threw the valley rather than threw the valve covers. I also installed a new PCv valve. I then removed some valve springs and a checked his valve seals. All checked out. With any aftermarket ported Heads the intake runners will be ported to the point that the intake rocker bolts will protrude into the runner. So I tefloned and locktight those bolts to seal them. When hunting issues like this down and dealing with a company like TSP who does not want to accept there product is at fault. You will need to go down the list and correct all that COULD be the issue when the whole time I know its the Valve guides and Seal combination. If they want me to chase down possibiltys then fine, I will. As you can see with the pic above this is a substantial amount of Oil and could only be there with a Head issue. Im no specialist, but will get Davids ride smoke free. End of Mission Statement :thumbs up:

My only question would be how did the inside of the intake look? Was it full of oil or all dry? When I had trouble I found massive amounts of oil in the intake. It was to the point I had to pull apart my FAST to clean it all out.

check the rocker pedistals to see if they are cracked mine was doing the exact samething. I could not tell they were cracked till i took them to get cleaned up and that is when the machine shop called me a told me all of the pedistals were cracked on the driver side head

I just read the link about PCV systems and catch cans. It's a good post and seems like a good way to clean up what's being burned, but it seems like a band aid fix to oil consumption this bad. If he's burning that much oil wouldn't that can fill up pretty quick?
