[T3] A question about oil pumps

[Dave Sanderson <porschedave@rennlist.net>]

<x-flowed>hi All

When we got Matt's new engine running we had a pretty serious oil  
leak from the oil pump. I have not experienced this before and was a  
bit surprised. After much foolin' around, trying different solutions,  
we finally realized that the problem was that the pump was too long  
for the space between the cam and the case. We have a pump for a flat  
cam, a flat cam and yet it was too long - but only by a very small  
margin. I filed the end of the housing, that is the section that  
sticks towards the cam and holds the gear that interfaces with the  
cam, by a thou or so and now, voila no leaks. This is a new 30 mm  
pump from Shadeck. Has anyone else had this experience. Is this  
something that happens with these new Brazilian pumps? Thanks. Cheers.

Dave
