Chaps,
Took my car out for a blast on Saturday and although the drive was good, when I got back the oil catch tank had about 0.5 litre of oil in it! (onyl
did 5 miles). On a previous car, my engines never used to push anything out?
Could it be that I drove it too hard when the oil was cold so it built up too much pressure and pushed it out, or is there another reason do you
think?
It's on a pinto and I have the hole under the exhaust headers blanked off and then have a take off from the crank case breather into a T piece
that also collects from the rocker cover and then goes into the catch tank.
Any ideas on what caused it, or if there's a problem?
Mark.
You've blocked the breather so the crankcase is pressurizing.
You need a hose from the top of the engine and the side of the block to end up in a catch tank that is open to the atmosphere, seperately not T.
Originally the block one would have gone into the inlet manifold to create a negative pressure in the block and burn off any oil vapour.

I had my old engine with the T piece and the catch tank is then vented to the outside via another pipe, so my thought is that both pipes (joined via
the t piece) are effectively then vented to the outside?
The only thing I am wondering is that on the crank breather the chap I bought the car from had fitted some kind of wire thing in the pipe that comes
off the crank breather, could this be sufficient to pressure the system, I left it in as I assumed he put it there for a reason, but should I take it
out?

Used to have a T peice on my Zetec. Found it was syphoning. Now have a Hose from the crankcase to the catch tank, but with a pcv valve inline where two hoses join together. The hose from the cam cover goes to a separate filter. Now i don't get loads of oil in the tank when i corner heavy, which was another problem i had.

There's a hole mid way up the block under the exhaust headers on the edge near where the block meets the gearbox.
I thought it was an oil blanked off but maybe it's water as you say?
