When I removed the timing cover, I found that sometime previously that the ventilator pump drive gear had been removed. What was JDs reason for installing this pump, and is it necessary? Should the gear be replaced Thanks for any Info. [Reply]   [No Email]

I do away with them when I can always wanted to find a big bore plug to seal the hole of and clean up the block.   [Reply]   [No Email]

It is plumbed into the air cleaner and when the air cleaner got restricted, the engine pulled oil out of the vent pump. Make sure the line is also plugged off. I use a ball bearing under the flare nut.   [Reply]   [No Email]
