Isuzu Rodeo: Have not ran codes, need an idea on harmonic balancer.

Have not ran codes, need an idea on harmonic balancer.
i have not seen the crank nor the balancer so i have no clue on their condition. I was told the harmonic balancer spun on crank and the woodruf key is gone. now how could that have happen. motor ran fine other than the ECT. we did lose the original woodruf key and got one a little shorter, but it fit snugly in place.
do you happen to have the specs for the balancer and crank?
what do you think happen?

lastly tech said the cats are shot due to engine running to lean. is that possible in the amount of time it was ran?

The mechanic he took it to said engine was running lean and burnt the cats up. The mechanic also did not like that there are two C clamps and heat tape at/on flex point in exhaust system, this is due to corrosion and bolts broke. Lastly, complained about fuel lines being toby close toto exhaust, and we did not relocate them

ok
if the exhaust is in as bad shape as you say...i would think the mechanic is right here,,and the cats and exhaust pipes may in fact need to be replaced,,due to the epa, the exhast must be correct
thanks

I agree exhaust needs work, but i dont understand why the cats would be bad since the seansors are before the damaged part in exhaust and there is no leak.

i uderstand...
but,there is no way for me to test the cats....so,you may need to discuss the exhaust with your mechanic....he is the one that can see them..so,we may just need to take him for his word on the exhaust
thanks
