Isuzu Bighorn 4jg2

Just got a 4jg2 and was thinking of doing some preventive maintenance. Like change timing belt, crankshaft oil seal and other PMS that needs to be done to make sure the engine would be reliable and last a long long time.

What is the life span of the timing belt?
If I do change the timing belt what else should be changed? (tensioners?)

Is there other things that I should also change?

its much better to change the bearings to. To prevent stuck-up of bearing

yup you got that right. I will have the water pump checked too when they open it up for the timing belt. Thanks

Replied your PM.

Sir, reviving an old thread regarding PCV valve for the 4JG2. Have you experienced replacing it? Is it available in the market? How much? Or can we just spray it with carb cleaner for maintenance purposes?
