VM Valve Spring Replacement?

TheDude · 05-09-2008, 11:24 PM

Is there a source? Or substitute for the valve spring? Thanks.

I found any spring will almost due as long as you bend the spring coil to pinch against the valve face lip. Many people including myself have found you can float the valve with no spring. The pressure from the source pushes the seal closed.

Take a autococker valve spring and a pair of pliers and grip a top coil and twist the coil smaller until it takes a slightly smaller coil. Then fit the coil over the valve faceand cut to desired length. Not much to it.

Most cocker and older spider valve springs work fine I don't if you still can get the but back in the day you could get a spring pack. It had three springs a red one = hard a blue one= mid and a yellow one = soft. It was like $5.00 at the time.
Anonymous Coward is right about crushing the top of the spring to. As seen here

The spring will stay on the cupseal which makes thing a lot easyer down the road.

Especially when installing the valve using the "no tool" method.

I once clobbed on a chunk of white lithium to make it stick to the valve, before I heard about crimping the spring.
