I've got a '98 tacoma prerunner with 140,000 miles. Its leaking oil behind the crankshaft pulley. I'm assuming there's some type of crankshaft seal that needs to be replaced. My plan was to replace the three belts and check out the timing belt....or should I just go ahead and replace the timing belt since I'm half way there? What about the water pump? Anything else? Someone recommended this kit.

any thoughts??

 

Excellent kit.....many here, including myself, have used it.

Do it all while you are in there. Buy a new crank bolt from the local dealer as it is a non-reusable part.

There are a couple of other 3.4 timing belt threads in past 2-3 days.

 

Came to say this.
