Presumably, before you rebuilt itWhen I rebuilt my engine I took off the oil breather and put my hand over it just to see how quickly it built up, second time I did it it blew the plastic cam shaft seal out with a whoosh.

No, sorry it was while I was test running it, luckily I was able to clean it up completely then put it back with a smear of silicone.Presumably, before you rebuilt it
how about this, regulate the oil pressure and be done with it ??

Excellent, thank you!Just the one on mine when it was on
Take care when nipping up with new o ring on I think there’s a gap between faces too much and it breaks
have you a blocked or partially inletI've tried my hand over the oil filler hole to check for excessive pressure. Felt fine. Today I thought I'd be a little more scientific

Found a kitchen waste pipe connector and taped a nitrile glove to it. Blew up nicely by mouth. Made a rubber gasket to act as a seal when I held it down on the hole.
No inflation of the glove what do ever. However, when I revved the engine it started sucking the glove in.
I'm googling negative valve cover pressure and it seems to be a good thing. Can it be too good though?
Do you mean the air intake, JM?have you a blocked or partially inlet
yesDo you mean the air intake, JM?
Don't think so, but will invwstigate. Do you think it could be creating enough negative pressure to be sucking oil through the turbo?
I hope there's nothing in there!Hope you didn’t leave a flannel in the inlet manifold like me got sucked into no 3 port blocking air and losing compression
I had loss of power and smoke with that
as you rev the engine the breathing system if original and working should suck harder as air and the fumes are pulled into the turbo, a blocked air filter or hose ie inner wall collapsing would greatly increase this,vac pump if there was a leak ie servo and hose would pressurise the engine ie suck air into the engine@jamesmartin ive not investigated intake pipe work yet as I'm tying plants up in the garden. Just wondering if vac pump might be faulty and creating the negative pressure? It'll be the original pump, so 24 years old.
Ok, vac pump probably still ok then.as you rev the engine the breathing system if original and working should suck harder as air and the fumes are pulled into the turbo, a blocked air filter or hose ie inner wall collapsing would greatly increase this,vac pump if there was a leak ie servo and hose would pressurise the engine ie suck air into the engine
it wouldnt do as the engine breather pipe is not under any suctionOk, vac pump probably still ok then.
This is the air filter

Nice and clean.
However, I took the air intake pipe off the turbo inlet and repeated the test. Glove did not suck in this time!
Time to take all the pipe work off I think!
But is the question, am I getting too much suction? i.e. A blockage?it wouldnt do as the engine breather pipe is not under any suction
