Hey guys, I'm having problems with crankcase pressure. Oil is being pushed through some various gaskets, but only after heavy boosting. Normal around town driving (I try to keep it under 8psi while accelerating usually, just for fuel economy) I never have any drips. Any ideas? I have no vacuum leaks.

 

Have you heard of blowby under load. It is the first indication of worn rings. As load increases gasses get past the rings at a greater rate. Cummins has a load test that measures blowby volume as indications of need to overhaul. It does not cure itself without dollars and labor input. Compression in a can will not fix.

 

Well that's what I was afraid of... boy does that put a not in my stomach.

 

Well I've begun looking around, and it seems that my best option is to get a short block to rebuild. Are there any blocks to avoid besides the 53 block? 1st gen blocks are the same, right?

 

As far as I know there is only the 53 block on 24valves engines. Where exactly did you find the short block at?

It was in Texas per a friend and I called to see how much it would cost to ship it and they had already sold it. I've got a few other trees to bark up though.

 

I read that valve stem seals coming off can also cause excessive crank case pressure. Is this common?

 

It has been for me

 

Well my front valve covers are the biggest leak source, so I'll check into that then.
