Thanks Aaron,
I’ll try that.
However, I recently removed the pan in order to check the shims on the mains and also to confirm the crank end play. The end play was way out and I decided to have the engine redone but have not gotten around to it.
I will try the clutch trick.
Mech 3,
Yep, if I remember correctly the crank moves back under power and forwards under engine braking. The limit is very little, just a few thou. Mine moves quite a bit, I did measure it, but decided to redo the engine and promptly forgot the exact measurement, but it was a few mm. I have no idea who touches what in order to make the noise.
Will let you know when I find it, but I don't know when I’ll get there.
Regards
Chris
