Good call Keith. I've heard of the shimming trick but didn't want to 'hack' a solution. But I'm now much more flexible (read: desperate) as it turned out the Lucas stabilizer hadn't fully resolved the tick. I dropped a .040"/1mm shim in the new pump and it was good for ~8psi. I'm now running about 62-63psi hot when cruising. For noobies, the shim goes in the hollowed bolt head where the screwdriver is pointing - photo borrowed from a nice member on Ratsun.bertvorgon wrote:Maybe you do not know..but...you can shim that pump. behind that BIG nut head is the blow off spring. If you put a very thin washer there, that will give you more oil pressure. Start THIN so as not to blow up the oil filter....
I finally pulled the valve cover off and noticed 2 things:
- 1 - #3 exhaust was not well pressurized and likely the cause of my repeated ticks. I'll go ahead and order a new #3 exhaust rocker/lifter - that will be my 3rd and I'm starting to wonder if there's an oil flow/pressurization issue there in the head...
2 - Intake valve 1 on #3 had damn-near 2mm of lateral play on the rocker arm shaft due to the clip being flared for some reason (proper FSM torquing procedures were used in the past). I managed to pinch the clip tight with channel locks and all seems well.
On another note, my filler neck solution appears to be working well once I solved a couple teething issues. I managed to POR15 a little of the intake lip which cause the cap to not seal properly unless I really tighten. I'll sand the paint down in the near future. Also, I reused the existing breather tube which proved to be too old and split where I flared a shortened portion onto the fuel tank. Fuel was coming out quite easily before my nose caught it. I've taped it up for now but will want to find a better solution, any idea where I can get a new one?
Finally, with the battery in the spare well I was getting sick of not having proper support in the trunk for heavier items. I didn't want stuff resting directly on the battery or risk shorting. So I fabbed up something quick that fastens to the spare wheel hole. It's not pretty but it holds plenty of weight now and keeps the battery isolated from other items I store beneath the cover..
