u know that horrible sound old deisels make first thing in the morning? lmao
Had my 20XE head skimmed ported and polished, ports matched blah blah etc, ive put it all back together and had it idling for over an hour now and it still sounds horrendus (sp)
drove it up the rd and back and it seems to run fine, all 4 cylinders firing and revs up nice and quick.
is it possible that the timing is ever so slightly out and the valves are just touching the pistons or is it more likely that its just taking the oil ages to get round?
also im running a mild cam so there isnt a great deal of clearence in there, one at the top here, the Q42H -
i dont remember it sounding this bad after i i didnt drive it for 2 weeks
