tapping lifters/oil filters [was: thanks 4 connector info]

[auditude at cox.net]

Jim,

Good call, man.  I had thought of this, but then I let myself forget a couple times.

Perhaps subconsciously I'm just trying to motivate myself into putting that cam in.  I need a little motivation since I've done the same job on my past Coupe GT with a Schrick instead of a Blausport, and had to redo the darn thing like three times before I got it right (cam timing too much this way, then the other way, then find the cam key on the ground, etc.)

Right now I've got an orange filter on the car, which I know better and don't like.  I think it was from my first oil change after buying the car, and I used up all my oem filters I had in stock.  I'll change the oil and put a real filter on there and see if it helps.  Granted, I'll have the cam out anyway to swap in the 272, so I may still put in some known newer lifters that I have somewhere.

I wonder why it's the lack of an anti-drainback feature that causes the problem.  I wonder if it is perhaps more due to a weak bypass valve in the filter.  Seems like the drainback would be like a check valve that would still allow flow in the same direction as the pump is pumping, and lack of it would still allow oil to pump in the same direction.  However, my thought is that a weak bypass valve would allow... eh, I don't know.  Who cares as long as the right filter works, right?

I'll post whatever it turns out to be, not that we need any more reason to stay away from non-oem and orange filters.

Later,

Ken
