Is this an 8 or a 16 valve head? ======================================== Trying to remember which 8 valve head cracked in cylinder no 3, mine (cracked) was on a 1983 car (not turbo, 8 valve). If 16 valve I don't know if the same problem applied. To test the rings for compression, do the compression test again and put in through the sparking plug hole a teaspoon of oil. If compression returns to normal on 3, i.e. comparable to the other cylinders then the rings on 3 are gone. If it helps a little. Regards Charles -- Please remove _removeme_ to reply.
