alright so me and the jeep hit 155,555 miles the other day...
when i bought it it had 148,000
and the realization of a couple things came to mind...the previous owner (although he is a great guy, i know him personally) only did the very basic maintenance and even towards the end end of him owning it, he barely did that
so my question is, are there any strange things i should check/replace/lube/grease/etc
Sorry didn't check... But you could change your diff fluid, flush your coolant. Use a turkey baster and suck out your power steering fluid, then fill with new, start the engine and turn the wheels lock to lock a few times and repeat untill all fluid sucked out looks clean (might not look perfect but better then old at least). Bleed the brakes if they don't feel very responsive, but don't top off the brake fluid unless you have new pads on it only fill it to where it was when you started. And always use factory spec fluids
It's good to see that you're going to give it some love
06 Rubi with some sort of double ended, chrome knobbed, cross threaded, infinitely adjustable, frequently breakable, worn out flammywhammers zip tied onto it.
It used to be a jeep thing... til that sh!t broke!
Clean out the PCV valve!
Its the elbow at the back of the cylinder head. It will have chunks of crude in it.
The Elbow doesn't come out of the valve cover but the tube coming out will pop off. It will help the "blow by" problem and any Jeep over 80k should have this done.
I used a pipe cleaner and the valve that is on the other end that goes directly into the exhaust manifold unscrews and I used break cleaner to clean it.
Blow By is when these valves get clogged up and its starts blowing oil into your intake manifold and eventually into your air filter. Can dramatically reduce life of the motor but I've seen blow by go for 40k more miles before a motor has to be replaced.
also, i no the nv231 is chain driven...
does the chain ever have to be replaced...reason i ask is ever since i got it
first gear make a whirling winding noise 1/2 of me thinks its normal the other 1/2 thinks its the chain whining
