Why? lordy why? the one is all locked know there is nothing but trouble when performing this to have two mechanics present...the amount of labor required would make you just want to fix the one...serious....trouble with a capital T~ the ECU and computer controlled devices are just the beginning~

Even tho there both 1.9????? The guy that had the car before me screwed the motor up and now it's shot.


well, perhaps I underestimate your abilities as a mechanic~ ED on wheeler dealers makes Everything seem so easy~ with could inspect and component at a time~ gotta ask...screwed up how? may not want to mess around with heat-warped parts~ your call, all depends on your skill level~ and matching...different years are usually redesigned~

Someone installed the timing belt tensioner wrong causing it to go out screwed up the head warped the valves.


DRAT...I hate that when that happens...especially with a customer's car..."you got some 'splainin' to do"...but Tear it down then..see if the valves are bent...and boldly repair it..machine shop service will be needed...but it can be done~...else go to the pick-n-pull and grab ye self a third motor...and take these back in exchange at your boneyard~ just a thought...a way out...for cheap~

I got a 98 tdi for $250 out of a totaled car with low miles that's why I'm wondering if I can switch the motors.

too much labor to look after your what I'm thinkin'~ go easy on your a Toyota...what will not break down on ye~


In short the 98 will not work in a 2002 car. For starters you would need the ecu from the 98. Most of the electronics are not compatible not to mention the wiring harness won't be the same. Its usually best to go with a used engine no more and no less then a year older or newer depending on the year of the modal. Unfortunately the cars changed to a different base between 2001 and 2002 so they are not compatible. Fixing the old engine is not usually an issue unless the pistons are damaged as this kind of issue can some times throw a ring. Your best bet would be to buy a used or rebuilt head. if you can do the work yourself the repair should be easy. I would sell that used engine for some extra cash if you already bought it.
