PCV based crankcase ventilation

[comeinhandy]

There have been other people doing their own similar systems before but in response to a couple of requests for photos of my particular PCV setup, I have written up the details in a seperate pdf file here for interest.

Thanks!

I've been thinking along the same lines, but maybe not such large connections into the existing cam covers.

Cheers,

Mike

Cheers,
I went for large connections to allow for room for the PCV valve and grommet and for a lot of room so that the flow rate of the vapours is reduced allowing any oil mist to condense and flow back down. I had quite bad oil blowing into the air filter with the original side pipe and straight connection to air filter, that I tried to make as many stages of oil trapping as possible. It may not all be necessary but the basic principle of PCV and a vent on each cover seems to be a common setup on a few 'V' engines I've seen, so I guess that is a good indication.

Nice! I can see you have spent a lot of time and money on that engine. How much does chrome plating cost nowadays out of idle interest?

Hello Alan.

I am dazzled by the shine! Please will you clarify the plumbing. I assume that is a catch tank on the N/S suspension tower. Input from PCV on N/S bank and output into PCV port on Holley? What have you done with existing breather on O/S bank?

John.

yes n/s cam cover contains pcv valve which runs to oil catch tank

from there it runs to pcv connection on holley

the original o/s cam cover vent then runs to undernath air cleaner base

which incedantly at service intervals has no oil mist or spray inside,which shows that system works all ok
