Title: "Corvair" pushrod mod and piston pin pressure oiling Post by: 181 on January 26, 2010, 00:32:09 am Did anybody tried Corvair pushrod mod? Corvair, a flat six cylinder, has a tiny hole in each hollow pushrod at the head end, right under the pushrod tip, to promote oiling of the rockers:

And does it work? Best rgs BB Title: Re: "Corvair" pushrod mod Post by: 181 on January 26, 2010, 12:33:39 pm yep alright and how did it work? Roller or conventional rockers? Thanks, Jan Title: Re: "Corvair" pushrod mod Post by: 181 on July 21, 2011, 09:31:31 am and another curious question:
anybody tried piston pin pressure oiling? Small hole has to be drilled or EDMed through the length of the rod and through main bearing+piston pin bushing to deliver pressurized oil directly to the piston pin. I know Mr. Pauter offer this as extra option for his rods. Would it be advisable to perform this mod on my H-beams?

Jan I was looking at a 2.0 jetta engine last weekend that came that way from the factory. If there is enough "meat" in the rod, I think it's a good idea.

I also thought about rotation but its probably not that critical, just helping and when all 4 have it, one is bound to spray in the right direction. Your oil pump must have the extra capacity to pump that extra.
