Will pull VC and look. Not having them seated all the way was my concern.

 

Pulled VC, everything looks just as it should. 16 valve stem seals, all have their spring thingys, they all look seated, nothing obviously contacting or ripped or torn. I dont fuking get it.

Can someone reassure me that stem seals are the only thing that can cause this and can in fact leak enough to cause that much smoking and puddling in my cylinders. Hug me and tell me everything will be ok. I just find it hard to believe, while at the same time, I dont know of anything else that can cause this.

I ordered these last night and should have them in time for the weekend.

How long have you ran it, are you sure it's not just burning out still or something?

I can't think of anything, but I kinda feel like I'm missing something obvious! There's nothing else above to drip down, right?

 

Slow

 

Ran about 20, maybe 30 minutes total. I just let it warm up, until the fan came on(205 degrees), I did that twice just to burb it and get the lifters to pump up, set timing, check for leaks, etc.

Im positive its not just burning the residual ****. Way to much smoke for going on to long. The plugs are covered and there is literally a tablespoon of oil on each piston. They were absolutely clean when I reassembled it.


This is what im racking my head about. Im just having such a hard time believing that new stem seals are leaking this bad, even with the vacuum the intakes see. I just cant think of anything else that could causing it.

The VC has a breaher on it, and I pulled the PCV anyway just to make sure the crankcase wasnt being pressurized. No help.

 

huh?

 

You didn't remove the oil restriction in the block between the head did you, it's not flooding out the head with too much oil?

 

I was just subbing to your thread! Hah

 

Did any of your plugs have wet threads. Any oil in the spark plug holes?<br />
<br /><br />You've run it enough that any leftover oil from assembly would be gone. That would happen fast.<br />
<br /><br />Can you pull the intake manifold and try and see the valves?<br />
<br /><br />Rent a boroscope?

 

Did not remove the restictor. Dont even know hwo to be honest.

cool

Plug threads were good, no oil in the plug holes. No leaking from VC to plug holes if thats what you were getting at.

Agree about running it long enough to burn off residual, that happens in the first few minutes and never makes near the volume of smoke I am getting.

I can pull the intake

What would I look for with a borescope?

 

<p>I would make sure the oil is coming from the valves.</p><p>Then depress a valve and see if it is coming from the seal.</p><p>You didn't install the seals right?</p><p>(this is why I didn't touch my valve seals, if it ain't broken beyond usage, don't fix it, thats my motto )</p>

 

My machinist installed the seals. They were "broken".

because reasons


But that was just normal wear for seals with 150k on them, not like what is going on now.

Just got home, will pull intake here in a bit.

 

Im so confused

They all "looked" clean. Any part of the aluminium i could get my finger on was dry to the touch. Some of the valves, stems, and end of the guides had the slightest of oil film, some felt dry, none were wet. I would take this to be normal.



Its really hard to get a pic of the piston but I tried my best. You can already see specs of oil deposits forming and the general wetness.






This pic as taken the moment before I set the head in place and torqued it down. Clean pistons, restrictor in place.






So what now? Rings? I dont know what else it could be, but how could replacing a head gasket and bolting on some **** blow the rings? Could I have forced all the carbon deposits into them when I cleaned them and surfaced the block. There was a lot carbon above the top ring, between the piston and cylinder wall, it was packed. Was that my piston ring? ****!!!

 

<p>I don't think not having rings would fill your pistons with oil. I'm guessing head gasket.</p><p>&nbsp;</p>

 

Head gasket was my first guess when this started, until I pulled the plugs and found all 4 cylinders were wet. I find it highly unlikely that the head gasket failed in such a way that oil finds its way into all 4 cylinder without leaking anywhere else.

 

To all the pistons though? Or is it all of them?

What does a compression test say? You didn't mention oil in the intake because there's none right?

I worked the carbon out from the piston by running it up and down, wiping the ridge each time.

 

Yes, all 4 pistons look equally oily. Havnt done comp test yet. Absolutely no oil in the intake, its squeaky clean. I cleaned the pistons similarly, I also used a small wire brush and small screwdriver to help coax some of the carbon out.



So I removed the exhaust to look, everything is covered in carbon. The turbo isnt leaking a drop.




Exhaust mani looked similar. I can just see exhaust runner #2 through the mani outlet and it looked wet, so I pulled the mani.

cylinder 1 and 3 are just carbon covered, cylinder #2 is wet, and #4 is drenched. There is now no doubt that whatever the issue is, its coming from the combustion chamber or head, whether it be rings or stem seals or HG.

#4



#2

 

I'd try a compression test, but with all that oil all over the pistons I'm not sure how much it'll tell you about the rings. Maybe if something cracked or if the gasket isn't tight it'll show?

I can't remember if there's room, but could you squirt some oil on the valve seals then watch to see if they leak down overnight?

 

Will do comp test regardless. Adian mentioned squirting oil on the seal, you can kind of pour it all over the spring and it looks like it makes it way in there. I did it on #1 intake valve, nothing seeping yet.

If comp test comes up good, I think ill just replace the stem seals as they are on their way, and everything is half apart anyway. I poured some seafoam in the spark plug holes for whatever thats worth, maybe itll loosen a ring up. Ill slap it back together and see if I cant get it to stop smoking. Maybe some revs will help? It hasnt seem past 2500, maybe 3k yet, as it has no tune. If it doesnt clear up then I guess i will be re-ringing and doing a rods only build with cheapo rods, unless when I go to do that, I find an issue with the head gasket. I was supposed to be tuning and loving boost right now :(

 

<p>Ugh, that sucks. I just don't see it being rings. Especially not all 4 of them.</p>
