I am installing a used motor in my truck soon it has 80 thousand miles..does any know how long the timeing chains last or when should you replace them ..are they good for 2 hundred thousand miles has anyone had one break on them ..thanks
The timing chain on a 4.2 should last the life of the engine. You would be much better off changing the intake manifold and front cover gaskets if you do anything - and if the engine is out of a 97 or 98 I would consider that mandatory.

Thanks yes it is a 98 engine,its going in a 97 150.I know ford fixed the gasket troubles latter on just dont know the date .the engine runs very well, i can get the date off the engine if that would help to see if it was updated and if it has the new gaskets..i think ford fixed the gasket troubles in late 98..ty
Thank you much for helping me save labor and a few bucks.I checked the engine its a little different than my 97 motor vac lines on the back on the intake,ford valve covers,ect.I checked the sticker it says 1-26-98 exxex engine winsor,I hope u are sure on the date i dont know how to find out,my old 97 engine has a sticker that says reman by ford .thanks if you how i can find out for sure please let me know..ty again
I've done lots of research on this and the date glc gave is correct. If the build date is later than 1/15/98 you are good. When I had my gaskets fixed a few years ago I asked them to check the timing chain and they said it was in great shape. Truck had about 245000 kms on it at the time.
