Video of my valve train noise

In this video you obviously can't see it but oil was being sent to my upper intake and exhaust. I have another thread about this but was unable to figure out which one it was. Sorry.

I thought it was collapsed lifters. I actually found three questionable ones when I broke it back down. I stool got a half quart of oil in my upper intake though.

Re: Video of my valve train noise

Have you checked to see if the oil is being forced through the PCV valve and tubing into the intake?That sounds like lifters that are not pumping up, but I don't know why unless they are damaged.

There was oil in the pcv tube. The valve was new and not stuck though.

Also I was not getting oil pressure so after about five seconds the pre primed oil had probably been pushed out of the lifters though right?

you said before that the screen was in place on the pcv? with that high compression you may need an oil seperator.

Yes, the screen is still there.

TH - How would I have no oil pressure but be able to have oil pump through the pcv and in to the intake? Id love to figure this all out

I just switched that out too, but with the lifter noise I figured that oil pump may be the issue. I have replaced that as well.

Are your heads plugged off in the rear? I'm sure they are just wondering.

It's not horrible, but it's not right either.

---------- Post added at 07:53 PM ---------- Previous post was at 07:53 PM ----------

Biggest issue is all the oil coming out my exhaust and intake.

i domt see it likely. if an oil passage cracked it would be difficult for the oil to backfeed into the intake from there (i think). also i think when heads crack they are more prone to do it between the valves. im not saying this is impossible but i dont think its the problem.

i wish you could have pulled the pcv when it was doing this, as thats usually how oil gets in there.

Yeah I didn't find find much other than an article that said the engine wouldn't run well and normally coolant would be in the oil. I don't have either of those problems.

make sure you set the pickup right. and remember what insaid about using tape on the screen so uou dont clog it with clay?

your old pump was a high volume? if so did you get another high volume? and what pan is on there? if its a high volume you need a 7 quart pan or you will suck it dry.

I took the hv off and put a standard m68 on there. It is not a 7 qt. I used the clay and got it a half inch off the bottom of the pan now. It was very close before.

yeah. you are better off with the standard. if you have problems this time. it would be better if you gave us a little time to come up with some tests. you may have prematurley ripped it apart. i understand the frustation, but we may have been able to get you a better diagnoses after some longer conversation. i feel bad that i cant answer all your questions and that you have went through all this. and it really sucks you are putting it back together without fully knowing what went wrong. but anyways my fingers are crossed that all goes well.

I did a compression test today by hand. Not ideal I know but all cylinders came out around 50 psi from hand cranking and I left each one for one minute and none lost any pressure.

when this first happened a scenario went through my head after trojan mentioned stuck ring.

i had thought that maybe a ring stuck. then with the oil in the intake going into the combustion chamber. it may have helped free up the rings. but just a scenario i had thought about. that would make senso why you had good compression on the test which wasnafter the original oil problem.

You don't have oil pressure?

Now I'm wondering if they left a plug out of an oil passage somewhere or if the block is cracked.

You will need to install some oil separator(s) in the PCV system and you need to be 100% sure you have adequate crankcase ventilation. Forced induction engines will increase the crankcase pressure considerably and you have to be sure that it is not pushing the oil out.

I'm also still wondering about the turbo oil seals. Is there anyway you can disconnect the turbo from the intake and exhaust and just run it naturally aspirated?

I had oil pressure for about ten seconds then it pretty much went away. I checked the plugs in the rear of the block and they were all there. Also, it is a new block not remanufactured.

Also, oil is coming from both sides of the engine. The turbo doesn't push backwards so I was thinking because I that the oil was not coming from the turbo. Oil was in the cylinders as well. That's all the detail I have
