<VV> On the subject of Clark's Oil Filter

[J R Read]

First, please understand that I'm not trying to bash anyone.  In fact, I 
feel that we Corvair owners are very fortunate to have vendors who are 
willing to expend considerable time, money, energy, and probably more that 
I've not listed in order to fill the needs of Corvair owners.  The PF4 went 
away and the Clark's organization stepped up to provide a filter which did 
not use that (in my mind) horrible U shaped gasket on the outer edge of the 
canister.

Unfortunately, there seems to be a quality issue with those presently in the 
supply chain.

While I do not have the ability to determine the precise problem, I AM 
willing to suggest that it might be related to the quality OR the number 
(possibly both) of spot welds which hold the ring to the canister portion of 
the filter.  That ring is what holds the square cut rubber gasket (the one 
we like) in place.

Attached is a picture of one I removed from my own car.  Note that the welds 
are located centrally between each of the six holes where the oil flows 
through.  So, is there a problem with the quality of welds?  Should there be 
two or three welds between each hole?  This is where I'm not qualified to 
answer, but I sure feel strongly that this is a "weak link" in the current 
filter.

Can it be improved?  I suspect that it can, but someone smarter than me on 
filter construction will have to answer that one.

Later, JR
