m20 .whirring sound

by Tassy75 » Sun Oct 26, 2014 7:45 pm

Have just fitted another m20 4speed into the EH. Am getting a whirring noise when sitting in neutral but goes away when foot is on the clutch at idle. But When foot is on the clutch when rolling it is still noisy?Also very noisy almost grinding when driving with 1st gear being loudest, 2nd & 3rd not as noisy and 4 there is almost no noise. My guess input bearings shot and the gears are shot also as opposed to clutch/ bearing issue?. Thoughts?

Sounds like box needs re-racing with new bearings

2nd hand box fitted today, no more noise, nice smooth gear selection, just need to sort the diff wine.
