i own a 90 ford ranger,2.9 litre,6 cylinder,4 speed,has 312 clicks on the engine,doesnt burn oil,or smoke,if i maintain the oil changes on it,and maintain frequent tune ups,when should i consider a rebuild on the engine?cant afford it,yet.

 

If it runs good, by all means keep running it. I don't know about the 2.9 v6's, but a good preventive measure on a v8 that has high miles and has never been opened, is to replace the timing chain and gears. The original ones had a aluminum gear on the cam that is coated with plastic. This flys apart after awhile, and the chain gets very loose.

 

i will certainly keep,it running,other then the noisy valves,or could be something else.

 

i had a 85 ranger with the 2.8 carb'd v6 with high miles as my first truck at 16. i put the truck thru livin heck. i just kept the normal oil changes and such done and the truck still had a good solid motor when i sold it 3yrs ago. the main thing is just watch over heating the 2.8 and 2.9's they tend to crack heads and such much easier than others do.
