Want this question answered?
Very likely
yes definitely, bent 4 exhaust valves on my 98, and she was locked up
it does that because it has either jumped time or ....jumped time ! :) :)
This engine (3.0L) is an interference engine so yes, the engine could lock up if the timing belt jumped.
If your engine has a timing belt and is an interference engine you can bend valves and cause a bunch of damage. If it is not an interference engine you can simply replace the belt and or pulleys and all should be good. Please note that if you were driving at a high rpm when belt jumped you could still have damaged valves even if its not an interference engine
since it is an interference engine, alot can be damaged, really depends on how much it jumped,if say one tooth you probably ok to just replace timing belt. If say the belt jumped 25 teeth or belt broke, then possible major damaged could result like valves bent, piston damaged, overhead cams damaged. now if your asking in theory what happens then this is what happens: the relationship between dual cams ( camshafts ) and crankshaft timing goes off to the point where the relationship between them is wrong to not let the engine physically turn correctly,( causing mechanical damage ), and electronically off for engine firing position ,cam sensor, spark plug firing timing and order. Either way it is not pretty !
Your engine is kaput.
It could if the valves made contact with the pistons in an interference engine.
You will know if your car has jumped timing by the way it starts up. If the engine is slow and sluggish, it could be a sign of jumped timing. Also listen out for strange noises coming from the engine or if it backfires, it is likely that there has been a change in the timing sequence.
The four cylinder Fiero engine has a bad problem with cracking the cylinder head. If the gasket is bad it is likely the head will need an expensive repair. If the car has the V6 engine it is possible to just replace the gasket The real question is how good was the engine before the gasket failed? Should it be rebuilt or was it not burning oil and in good condition before the failure. Did the gasket failure cause any damage to the engine?
depends how wrong ? as in how many notches out ,if worst case it will bend the pistons and damage valves to the point of engine is perminantly damaged loss of power then eventual non function ,i have the same problem in my car had belt fitted incorrectly or belt jumped or slip but engine now no good !! now saving for replacement engine !!!
Yes, they are both 12 volt systems.
