Why do they usually leak?  Does it have anything to do with overtightening the filters?. Some people insist on ignoring the manufacturer's instructions, when installing a filter ..

Here I go with my $.02 worth again but please stay with me.  I think the filter adapters are getting too old to perform their job. That is, the steel is loosing some of its memory after 50 years of constant tension and thousands of heat cycles. With the adapter placed on a flat surface there should be a gap from the center section that contacts the engine block and the flat surface it's placed on. The more the better.  This is what establishes the applied pressure against the gasket and if some or all of the "cup" is lost, then so is the sealing no mater how tight the center hold-down is tightened. Some say use no sealer on the gasket. My last build I chose the thickest gasket I could find from all the loose gaskets and used no sealer and no leaks, this time.  Oldcarmark found what looks like the answer to this problem. If I had known of this turned adapter I would have bought one in a heart beat. Well, next time. Hope this helps, JEFF.........................................

Spin-on oil filter adapter Leak Fixed!!!

Two things: 1. The soft rubbery gasket supplied with the kit from Mac's "squished" out from between the adapter plate and block; I replaced it with the gasket from a FelPro gasket kit (this gasket was semi-hard rubberized fiber) which "held" it's place.

2. I took Ted's info on "whacking" the adapter so that there was a slight clearance between the block boss and center adapter hole with adapter into place [without gasket!!!]. Thanks Ted!

Between these two details, NO oil system leaks and finally running for first time: Started-up right away and SOUNDS NICE, with NO "unusual" noises present so far; also, 40 PSIG oil pressure at full temp "idling" at ~ 1,000 RPM using Shell 15W-40 (with the higher ZZDP). This is on a "refurbished" (not rebuilt with totally new everything) 292 bored over to 297 CID with "used" (but very good shape) ECZ-G factory heads, an ECZ-B intake manifold with an Edelbrock 1405 carb., and the "used" '57 312 factory "high-lift" cam with it's matching factory lifters. So far -- so good.

I do still have a very slight coolant leak at the thermostat bypass connection to the top of water pump and am hoping that this may "go away" with a heat-cycle or two (I've had that happen a couple of times before over the years). Otherwise, no big deal to "fix", if need be; just another small "pain".

One other issue now: I need my "dual action" fuel pump rebuilt: Another post in that regard.
