Q&A

Is there only one crankshaft seal? I thought there were two for my car, someone had told me. Also, when I bought this car, it had 125000 miles on it, and now it has 167000 miles. Would it be a good idea to change the timing belt right now because I was thinking that since I do not know if the previous owner did this job or not, but even if they hadn't, the timing belt wouldn't have lasted me until now, right? Can I assume that the previous owner must have done it, which would give me some time to do this job? I'm just concerned if I should get this job done right away or not. Thanks.

Your engine does indeed have two crankshaft seals one at the timing belt end of the engine and one at the transmission end of the engine which would require the transmission to be removed to be fitted (would not be part of a timing belt replacement).
I never assume the previous owner did anything. Unfortunately people are often neglectful.It is how ever unlikely the timing belt would have lasted until now if someone had not replaced the belt by now.

If the timing belt was never replaced it would hardly last until now but if you have no actual record of it being changed for piece of mind it may be est to replace it. These are a non interference fit engine (if the belt brakes it does not destroy the engine).
There are two crankshaft seals one at the front of the engine and one behind the flywheel/transmission side of the engine.

All that for $200? Use must be using used parts on a toy car.
