st170 help
Can any one help i no ive posted before about valve clearances but i have been told that the inlets should be 0.11-0.18 and exhaust 0.27-0.34 mm but i
have for no 1 inlet 0.13/0.10 no 2 0.12/0.13 no3 0.13/0.13 no4 0.13/0.9mm
and outlet
no1 0.15/0.15 no2 0.15/0.15 no3 0.15/0.15 and for no4 0.29/0.13
no 4 seems way off i did have a new exhaust valve on number 4 so this might be why. do the rest sound right to you i will phone ford tommorow to find
out what they think are the right clearances also this engine was running fine before i burnt a valve on no 4 and cracked the head with very little
tappat noise now it is tapatty i thought i may have mixed a few buckets up but looking at the clearances i dont think so. also there is numbers very
hard to see but they say p201 p109 ect what does this mean. Any help would be very greatfull.

If thats a Zetec wouldnt a Zetec forum be more useful? Having said that im sure there are people on here that would know but you just gotta hit the
right time on the right day

No 4 inlet at .9mm is a bit on the large side and all the exhausts apart from no 4 look to be on lower limits, to small a gap would not make it noisy
though, maybe it is just no 4 inlet that is incorrect.
