PSD could you add a collection system to the design so we could spare the driveways from geting greasy? Just a thought.

 

It is in the Tech Folder.....has been for a long time...I keep forgetting to look there

 

Are you talking about the stock design? Or, guess I don't understand. 'If' this CCV reroute is performed, we have the crankcase on one end and the hose to atmosphere on the other. How do the crankcase gases get out of the crankcase, through the filter, then out to atmosphere? Is there a much higher pressure in the crankcase than atmosphere? enough to push the gases out?

Thanks.

 

The crankcase gets victimized from the blowby of the pistons. That high pressure diesel combustion blast that drives the pistons down has some leakage past the piston rings and this gets into the crankcase. With no where to go, the crankcase would get a higher and higher pressure and then grenade your engine, showering you with cast iron shrapnel. (just kidding). Your oil dipstick would blow out first and shoot through your hood. The CCV vent could work just fine at atmospheric pressure.

My friend got a new Z06 corvette and floored it without break-in. He kept blowing his dipstick out from too much crankcase pressure and setting a Check engine light every time. He never gave his piston rings a chance to seal.

 

Thanks all! BTW, how come this topic doesn't draw the crowds that the EGR disconnect procedure draws? Both procedures help prevent gunk build-up in the engine.

 

Good question....

 

They would be directed back through the combustion chamber if I understand correctly.
There is a higher pressure in the crankcase to push the air out, and also a lower air pressure in the intake, with all the air coming in.

 

Hey great post! Just what I was looking for too....

There is another mod to go along with this where the CCV is vented through the exhaust.

 

Probably should think about putting a 1-way check valve in the line for those who like to ford rivers.

 

Good idea Bob, have you tried it yet?

 

If you had a snorkel installed, and performed this mod, would that be enough?

 

WHO? ME? Ford rivers? Maybe if they are not over 6"deep over a concrete bottom. That is as close as this coward will ever get to river fording!

You would also have to look for and seal every one of dozens of vents, electronic devices and connectors. I just remember trying to get running a 63 corvette that had been in a flood. It had water in everything and was corroded at every electrical junction.
What a mess.

 

hehehe...

In the wet season our truck has on occasions had to ford up to 4' coming up our driveway (part of it is a natural flood plain), fortunately it has rocks on the bottom though.

And no, I don't drive my car then... although one of our workers drives his 83 Subaru straight through it (and it doesn't have a snorkel!!!), I have seen it half way up the windscreen on that thing, it amazes me.

 

Australia looks like Hot Rod Heaven to me! Can we import those cars and little trucks to the USA? They are really cool. I'm 60 yr old now, too old to imigrate but if I had know the different directions the two countries were going, I would have jumped long ago!

 

You got top love it down under...I agree with Bob....they got the best of both worlds
Fast cars the water drains the "other" direction and being that far down...you must have less gravity...therefore quicker times when racing

Pretty smart I are for figuring out their secret
