Hey folks,

as you can read in this thread I had some problems with valve clearance on 1 valve. The gap grew 2 mm in about 80 miles. Because of the extreme growth in valve clearance it made me think it could not be the lifter. (or camlobe since lift was unchanged)

Today I took of the head to have a look, and this is what I found:
The contact surface of the lifter where it meets the pushrod had been completely ‘washed’ away. The pushrod contact surface looked ok, I had also checked that before.

Never seen it before... Check out the difference between left and right lifter (right=wrong). You can clearly see the amount of wear.



I put the engine back together using new lifters, and different pushrods and also changed oil and filter. So far so good…

Cheers, Ben
