Blocking off 5cyl crank vent.

[carl]

I'm wondering if there's any solutions out there other than rubber nipple over pipe opening? My oem neck/pipe that's press fitted to the block leaks oil when doing hard pulls (covering the bottom of the car in nice antirust lol). Would be cool to find something alu or thick metal where i could weld a AN nipple to.

Dear Carl

You don't want to plug the case vent - ever. The pressure is there from combustion pressure getting past the rings. It must be vented. You need a catch can with an oil vapor separator. 034 and others sell several of them.

The vent body removes easily with a little hammer and chisel work. It's a very weldable steel, if you wanted to put a threaded fitting on it, or increase the size to something not tiny. Larger hose means lower velocity means less likely for oil to stay suspended in the blowby wind.

If it's just leaking, then you have a bad hose, no need to reinvent the wheel.

Thanks, yea obviously the engine needs to vent somewhere, i've seen a few cam cover solutions, made me think there might be something to block the one on the block. I guess i can buy a new unrusted/cracked oem one to weld on but the metal is so thin, makes it trivial to weld a thick part to it.

Anyways i was greeted with this yesterday:

Probs some bent valves, etc. Happened on a almost new geba water pump, press fit pulley spun off, effin sucks.
Pump turns smooth by hand.

Ouch, that's not good!

Yea just ran a comp test yesterday, 0 psi across. Effin sucks.
Hoping the inconels aren't bent. At least no valves snapped to kill everything.

Yeah, stay far away from that geba stuff...

[carl]

Yea, i sure learned the hard way on that one, funny thing, the audi sign is stamped on the back of the geba pulley. New graf pump on it now, adding a bolt to make sure next time it doesn't spin off.

Looks like all intake valves touched the pistons. The exhaust ones seem ok, well pistons and valves are unmaked and they seem straight so far. If that's the case, not so bad.
