Cool How to stop the PCV/Breather<s> from gunking your engine

OK I'm comming up on my third month of this pretty soon.

Crank case breather are stupid. How wants to suck nasty oil from the cylinder head into the intake!? Ugh the filth!


The obviously easy way is to simply disconnect the PCV, and front head breather. Unfortunately that leaves the oil to simply blow out by itself into the atmosphere. Nast smelling!!! Ther is also no vacuum sucking blow-by and other goodies out of the head! NOT a good long term solution!



So it's this easy! Cut off a square of panty hose about 1" to 1 1/2" wide and put it on the PCV / Breather fitting. Then slide the vacuum hose over the fitting (and consiquently the stocking).




1) Oil WILL NOT get past the nylon!!! No more nasty intake!!!
2) The Nylon WILL NOT MELT
3) As can be seen if you simply vent your front crankcase, there IS NO spent oil, OR SMELLY ASS FUMES venting to the atmosphere!
4) THIS IS FREE

Na My dog likes to play with them.

She's hillairous, when not playing tug-of-war with the male (and always wins, at half the weigh) She'll stretch out on the floor, take the waist between her front feet, and stretch her nose out in them until she's literally half way inside them LoL!

She apparantly either/or:
A) Think's she wants to wear them
B) Likes the resistance, or "snapping" feeling from stretching her mount open against the nylon and gawing on it (when it's stretched out)

So we have tons of ruined clothes around the house. She's a total freak tho... Only socks, and underware does she attack LoL!

I use a cheap fuel filter (kind for engine generators and pressurewashers) that filter general crud/ sand etc.

It is a nylon mesh.

The PCV system is actually an efficient way to collapse the bubbles in the engine oil to prevent foaming, and consider this, in dry sump applications, where the crankcase is under low pressure, you get powergain at the crankshaft.

Toyo that sure is a mighty interesting thing that jaguar guy has built there. I'm not sure if the guy's principles are sound and even if they are, it looks to me like it'd take hours of fabricating and more parts than a cuckoo clock to make that thing.

I've been meaning to plumb in the clear plastic fuel filter into the pcv line from the plenum - some say that works and im willing to give it a try, if it will keep the tb and intake butterfly cleaner.

Back in the day I had a car with that problem. I took a renuzit (sp?) freshener and gutted it. Cut the hose and drilled out the ends of the freshener so the hose ends would fit. (with a little help from plumbing parts and silicone) A piece of foam (like mower air filter) was inserted. Every so often I twisted the body apart, dumped the oily gunk, squeezed out the filter and reassembled. Hey, it worked!
