SOURCE: HELP!!!!need timing marks for pajero 94 2.8 auto *** import

there is a little mark on the crankshaft which you line up with the 'o' mark on the casing ..
remove the cam cover and look at the cam you should see a nob on the cam about 3 th lob and that should be facing just left of the engine ..
if you have a turbo there is two notchs on the injection pump pully ..if turbo there is a 't' mark on the rear of the cover the notch on the pully should mark up with the 't'..
the timing is set..

SOURCE: when should you replace the timing chain?

if you have a timing chain and not a belt for the most part it the life of the engine itself if the engine does not jump time you be find and check out autozone.com to see if they have you car listed and you can also go to your local library for pictures and diagram and information on your car and this is something i do myself on my cars just so i know how they work.

SOURCE: timing belt or timing chain?

You 98 Corolla has a timing chain that it internal and need no normal maintenance. It uses a hydraulic/spring tensioner to keep things tight and as long as its quiet, everything is fine.
Your drive belt (not to be confused with a t. belt) is the external belt you see on the passenger side of the engine. It drives you alt, water pump, A/C and power steering. It uses a spring loaded tensioner to keep the belt tight. These can weaken over time and cause a rattle noise and belt slippage.
