hi all

if you suspected a valve problem.. but checked the compression on all 4 cylinders (cosworth engine) and all 4 readings were identical and at 9 bar (low comp engine) would this deduce that all valves would appear to be ok and not bent?


thanks

 

oh dear, i seem to have 'newbie' itis

 

was that a hottest or cold, i believe i done a cold a long time ago AND SHOWED 8 BAR IN EACH THAT TURNED OUT TO BE FINE

 

warm test apples...

thing is , timing deffo went out on the belt.. im concerned about valve damage..

pistons have valve cut outs, but i did a comp test and all pots were the same

i re timed the car... started her up and all was fine.. but then she spluttered and cut out and now wont start.. about to check compression again.. but what if all readings are fine?

 

have to admit ive never eard f a cosie not damadge valves in similar circumstances a matter of fault diagnosis im affraid, but id be well happy if comp test is still good atleast the big bills are outs the way

 

hmmm, off to do another comp test now..

any one else any ideas?

 

leakdown test would be better than a compression test, but if its reading at 9bar on all of them it sounsd like you got away with it.

you still may have cracked the guides etc though, i would take the head off and remove the valves as a matter of good practice to check.
