84 Honda Accord, Timing Belt Failure
Q: I have a friend that lost his timing belt. I know thatís really bad for a Honda. I did a compression check and it came out as follows, 125, 115, 110, 75. The only thing that makes me wonder is that the car will not start at all and he has gone through 2 distributors because as soon as he cranks it over, it instantly jams up and you cant turn it. Any help would be appreciated. He wants to junk it but Iím just not sure that there isnít another problem.....Lisa (not a stupid girl)

A: The engine cranks over fine without a distributor, but jams up with the distributor installed? If so then there are other problems to be addressed. But, the timing belt did fail correct? Itís a rare event when a Honda engine does not receive internal damage when a timing belt fails. Before spending too much time or money on a vehicle this old I would recommend confirming internal engine damage. The compression test you performed shows that cylinder pressure is down and the last cylinder tested is too low. But the compression test is not a valid test if the damaged timing belt hasnít been replaced. I would recommend a leak down test to confirm valve damage or a close inspection of the valve stem clearance. A high amount of clearance is a good indicator that the valves are bent and cannot close correctly. Lisa, stop by the shop, there might be a job for you.
