Well first, jeeps run normal at 210 electric fan on around 215-218. Normal oil pressure is like 40-55(60) driving and 20-30 sitting. Jeeps use 10w-30 or 5w-30. Never seen someone use 20-50. Maybe yes but if so then someone else here will have to confirm that
Edit: get the code read at any auto store and post codes

On another note, I changed my spark plugs and wires today and noticed I have oil slowly leaking from my oil cap. I've read this could be a PVC valve issue. I'm going to check my hoses for pinches and my air filter (even though I just changed it recently and didn't find any traces of oil), anything else I should look for?

I checked my oil level earlier today to see if I was burning oil from my previous concern and while I was under the hood I cleaned the valve cover from oil and pollen. Later in the day when I went to change the plugs and wires the oil was back. Are you thinking of blow by?

It's a mystery
Has anyone else experienced this??????? Done the search's and all that. Temps still going up. Here is where i stand.
Rig runs fine at idle/low speeds. Doesn't warm up till I hit hwy speeds.
Dunno what to do? Prob will replace radiator, water pump, fan clutch, and coolant sensors for both fan and guage to be safe.
Or do i just start with sensors first.
Could a sensor do ALL OF THIS TO MEEEEE?!?!?!?!?!?!?!?!?!
I WANNA WHEEL NOT WRENCH!!!!!!!!!!!!!!!!!!!
Praying someone else has had this pain and can help me with mine.
Thanks for the help, listening to me whine, and bearing my burdens.

- Temps climbing to the brink of red if allowed when at hwy speeds.
- Runs fine in cool weather and at idle/lower speeds. Will do that all day no prob. Won't even hit 210* sitting there.
- Again - doesn't get hot until greater speeds/demand on system.
- Flushed with hose, no actual flush mat'l, new tstat, new rad cap.
- Washed off radiator w/ pressure washer at car wash.

I'm having what might be a serious problem.. This could be impossible to diagnose with just my poor description of what's happening but I'll try anyway.
For the last two weeks (and no "two weeks" does not mean 6 months) I've noticed a chattering sound coming from the engine. I can hear it when I'm idling and when I'm driving pretty slow. It seems to be consistent and acceleration or nothing that I can do seems to effect the frequency of the chatter, loudness, etc. I popped the engine finally the other day and noticed the crank shaft pulley seems to be wobbly while the jeep is running. Could these be linked in any way?? Does anyone have any more insight? Thank you!

Boomroasted, Is the engine throwing any codes? Off chance noise could be from the flex plate, try checking loose bolts and cracks. Is the pully loose? If your ideling and have the hood open can you tell where about the engine the noise is comeing from?

Also, I just remembered this and it could possibly be related.. If I'm driving through an area with my windows down with objects and buildings close to the road I can hear a high pitched jingling noise when I'm riding on bumpy asphalt like something is definitely loose.
And thank you for the quick response. I love this forum.

Start by taking the fan belt off and check the pullys. If there loose you can tighten them. Also while the belt is off, turn the different pullys by hand to check for grinding/binding.
The flex plate is where the engine connects to the trans. There is an inspection plate, remove the plate and you can veiw the flex plate( you'll want a flashlight for this) your looking for hair line cracks around the bolt holes, also for loose bolts.

I don't believe the motor is directly grounded to the body. Should I ruin a dedicated ground wire from the engine to the chassis?? Well this help with alternator noise in the cb?
