help shimming 7m oil pump

[kitt]

Im shimming my 7m oil pump, but where the washers are ment to go between the spring and the plug, the spring sits inside the plug itself.

My question is, does the shim have to be measured from inside the plug which would mean getting washers small enough to sit inside the plug, or should i measure from the beginning of the thread on the plug.

WHAT? just put 7mm worth of washers in there, then tighten everything back up. EASY, should take 30 sec. to do it. Yes inside the plug

5mm is plenty

the spring sits inside the plug approx 3/4mm (not measured) but thinking if i put a washer across the top of the plug to make up the distance.. less washers=less weight!!

I say 7mm, you say 5mm, others say 10mm. LOL

But ij is god....fuck what everyone else says..

"others" are wrong.....

Anything over 5mm and you risk coil bind in the spring and uncontrolled pressure spikes when the oil is coldNthick

As always I have a reason for doing things I really don't just pull this stuff out of my ass.

Cause that weight will gain you a full second on the quarter mile!!!!!!!!
