98 Sonata 2.0 DOHC timing belt

[BorisTKitty]

1998 Sonata broke it's timing belt while wife was driving. Is the 2.0 DOHC an interference motor? Is the motor broke or can I just replace the belt?

Yep its an interference engine. You probably have some bent valve stems. It should be on its third belt by now, which one is it?

May not be the belt. Engine turns (including the cams) to a point and then stops. With sparkplugs out and turning by hand it turns over until it stops, more pressure will cause it to overcome whatever is broken/bent but it will stop again. Car was totaled in a rear end accident a year ago so I am not going to tear it apart.

Sounds like the pistons are hitting the valves when the engine stops. Any physical damage to the combustion side of the plugs? Probably needs new valves and maybe cylinder head.

I did not see any damage to the sparkplugs.

Probably just needs valves then.

just needs valves...
Even if the head has bent valves, that's not how you do the repair...the guy gave you a clue why the car has stalled. Of course a GM tech wouln't have the foggiest idea... You wanna know what happened to this car, "Hyundaitech"?

The guy said the camshafts turned...so it's not the timing belt. It's the balance shaft belt that was snapped. It is a well-known issue that, when that happens, the flying debris destroy the crankshaft sensor. No CKP singnal => engine stall. The real mystery here is that "hyundaitech" is not aware of the issue.

Um, Mr. Theta..... did hyundaitech piss in your cornflakes, or sleep with your wife? You seem to have some real deep issues here; this is like the fifth time you've baited him. Would you care to enlighten the group? He seems to know what he's talking about, but I could be wrong.
