Re: Broken timing belt on my 90 4runner

Thanks Clyde, I'm the shade tree guy :-(. I'm not quite sure what you meant
by a full rotation off. The two cam on top is a bigger gear, and the crank
is a smaller gear on bottom. The bottom gear has to rotate a few times
before the top cam gear can line up. I checked the chilton repair manual and
it didn't say anything about the possibility of a full rotation off. Can you
explain what you mean?

I hope you're right about the valves not damaged, because it will be a
nightmare for me. Are you a mechanic expert? How do you check if the values
are ok?

Thanks in advance.
