90 civic timing belt = blown valves?
several months ago my timing belt on my 90 civic broke and i coasted to
a stop on the side of the highway. i took it to the shop and they said that it wasnt even worth replacing the belt cause this year/make was known to blow valves when the timing belt breaks. anyone know anything about this? if so, this is a real bummer and i need to start searching for another car. thanks. -aj |

I'll second Tegger comments, my belt broke, ( at only 60k kms, cheap canuck
tyre brand belt, or maybe it was their workmanship) anyways Had the car towed to a mechanic, said the same thing, aint worth it. I asked him to check it, and I would pay the labour. He phoned a coupl eof hours later and said he was ordering the new belt as the valves were fine. I was lucky, hopefully you are too.

wow, these responses are greatly appreciated! what an awesome group!
after reading your guys posts i think im going to just take it in and see if they can check it out for me. the car itself is pretty high miles - 170k or so but im on a tight budget at the moment and absolutely cant afford to get rid of a car that only needs a timing belt. i havent checked the boards cause i figured it'd be awhile before i got any responses, guess i was wrong. alright, once again thanks for all the responses! -aj |
