When I think / whine about how slow my ohv 4.0 is I think of the "other" 4.0 .... not to make you / or others feel bad but... get's me over my whining quick.... ...it will possibly out-live me.... especially being a secondary vehicle...
When I bought Her I did an oil change. I only had about 1500 miles on the oil change. For me it is a toss up on what to do. Get an 07 or newer 4.0 sohc replace the cassettes and gaskets and go that route or get the 97 4.0 ohv and wiring harness and plug her in. Would like to do the easiest way to have her last a while longer for me. As for my old motor I think some bearings were thrown and I do not want to go that deep to fix the motor. So I will be replacing my motor. Which one still in the air a little.How about fixing it
Then change the oil more often
Look how the old overused oil killed your guides
Fresh oil all the time and ...
Just my small amount of knowledge I have on the sock motor
OK Thanks I really thought that was a thrown bearing. When I was turning it to get the torque converter bolts off I heard some noise that was inside the motor. Not sure how to explain it. I guess what I really need to do is put her on an engine stand and see what the heck is going on.The tensioner leaf springs in your oil pan picture?
Normally no need to touch anything unless you have bent valves
Then I'd go the junkyard engine and new timing set route
So Far I have not had any issues with it up to 3". I have Limiting Straps to make sure they do not go any further then the 3" and have had no issues. A little rough as in ride but I am happy with it. I am starting to build up parts to do an SAS. but that will probably next winters project.love the build! how are the 3" keys working out for you? ive heard not to go over 2" for the life of the 4wd cvs (which i assume you have because you went to a 1354) i currently have 2" but i would be interested in another inch!
