So...My car runs great, abosolutely perfect usually.
Starts and warms up in the 24' deg weather here, good heat, great power, fun slides!!
But why the HECK do I have so much blow-by?
I have a good Cb performance breather set-up.
From oil filler, and each head to the breather, and I put a little K&N filter poking out of the breather top to vent it.
But MAN alot of oil fumes come out of that thing- enough to leave a little puddle and have some drips of oil running off the breather- on a 40 mile drive....Compresion is great, 145'ish on all 4 and I get hardly any smoke- just a puff when I rev it up and shift- I guess thats valve guides..?
But what are some guesses as to why I have so much case pressure?
cheeeeers!

I aint too worried about it actually.
The engine was rebuilt 9 years ago- 14,000 miles., by the shop I worked at.
I actually remember pulling the engine out and tearing it down...I HATED 914's!! Though less than all the other Type 4's (busses, 411's..)
try hearing this all day: "Bob- go pull that alternator on the 914, pull the head of that 76' Bus, do the fan/pulley seal on that 72' bus". I thought Type 4 engine were the biggest shitholes. Don't worry, I'm converted.
Anyway, the p/c's are Mahle- and were new. And I actually had to seal the breather top to the body because I got sick of the oil dribbling out the side. And I drilled the top and put a K&N filter on there to vent it. I don't know what the deal is, dont really care, it runs great and if it blows up I'll rebuild it.
Maybe it'll last until I get a real job and can afford some real parts ...maybe even from that J-aby guy what's always got some fancy idear how to get mo' power....
