So, I've had a noisey tappet since i bought the car a year ago, 94 cooper spi. Had the head off and fitted 1.5.1 roller rockers from minisport thinking this would improve the noise, but NO it's still there.
Doesn't matter how many times I adjust the clearances, rockers aren't hitting the cover as the noise is there when the cover is off.
I've done the screwdriver to ear thing and it's 8 and 7 that are making the noise, 8 is loudest.
There was a little sideways movement on 8, added some shims but didn't solve the issue.
Does anyone have suggestions as it's driving me up the wall, could it be the Cam or the followers?
