catch tanks

[JT]

Onto standard pistons or oversized??, as Merc say's comp test, also didnt you say marsall's pulled you and told you about blue smoke on over-run?, that suggests oil pushing past the rings unfortunatly mate.

I'm pretty sure the smoke they were seeing was not from the exhaust,but from the PTC. When I fitted the new air hoses,the ptc was left detached from the air intake,but still had the valve on the end,so when I lifted all the oil residue from the PCV was just dumped out the back.

Having said that,it still means the oil was under some pressure..........

So today, I will try an organise a test and will report back with results.

cheers

Evening....

Mr t5stealth to the rescue!!!(again) lol

pressure tested it for me and we got these results,written on the bench,couldnt find any paper at the time! lol


but what i did notice today,after I raised the catch tank and put a drain back to the sump,I had the white/watery stuff in the catch tank? as per jamest5r's ......


so here I am thinking it was just bad positioning of the tank and the lack of drain back to the sump??
anymore thoughts?

thanks again to t5stealth!

What I would do is put the box back under the mani and run the catch tank from that, by blocking the other holes you might be creating pressure??? It was there for a reason

Good bloke that Mr stealth helped me out in the past also

Mine still has the box under the manifold, one pipe just runs to the tank and the other is still supplying vacuum

Now I have put a drain back to the sump I don't have any blocked entries/exits.
But yesterday, I did run the engine without connecting the catch tank and all seemed fine, but I guess we won't know for sure till I get it back on track??

edit:which is now a week thurs

The alternative, I found a baffled catch tank with 2 entries plus a drain. So could plumb in the cams and block separately, but I don't know if that would work??

ok, problem still exists

thinking back, I believe the engine was leaking oil from the PCV area of the engine when it was standard.
what would cause the crankcase pressure to rise on a standard engine, with the exception of a blocked PCV????

failing this, I think I am looking at a new engine
