I havent considered that, but im undecided on what I want to do with the hood as of yet. It's got 2 small rust spots, both having maybe a 1/8" hole that have been driving me nuts... but I got the jeep real cheap, and been more concerned with all the mechanical/drive ability issues. Next is a...

I'm not 100% sure I understand everything you said, but I've taken into account that all the bearings are unlikely to have worn evenly (there's a possibility one or more may have very little wear) and the flow there would be greatly impacted. But for the bearings that did wear, I would get more...

I'm not so much worried about idle, as I am max oil pressure being so low at higher rpm. Basically the 10psi at idle and 10psi per 1k rpm gets surpassed before 3k rpm (more like 2500 in my case). At this point I feel my options are, run it as is and risk not enough lubrication under load, or try...

I plan on switching to a higher viscosity next oil change, I just had the 10w30 on hand from when I bought everything to replace the head. Was hoping the oil pressure would come up again being it suddenly dropped when the coolant leak got worse, maybe had a max of 200 miles on it at that point...

Forgot to mention that the oil I put in the other day was 10w30 again, just being I already had it on hand.

Honestly, I'm thinking the engine was rebuilt or replaced at some point. The block looked like it was shaved, lowest compression reading I got was 135psi on cylinder 3. The rest were 145 and up. Didn't really have any ridge when the head was off. My main concern with the low pressure is that it...

I understand and agree, but wanted to get a jump on info before digging in or the thread sitting too long. I'm half expecting to find worn bearings though and wanting to do everything I can to save what parts I can while I'm already in there. Plus, I'm really enjoying this learning opportunity...

I'm looking to pull the oil pan some time in the next week or 2 to check the bearings, decide what to do with the oil pump and have some more questions I hope you can answer or post a link to an already existing thread on it? I've never gone into depth with engine rebuilds, it was always...

Throw a bottle of dye in the coolant to check for the cracked head if you don't see obvious coolant in your oil. I just recently had a cracked head, only symptom was coolant loss and eventually oil pressure. Had a pressure tester on the system for over 2 hours with 22lbs, did not drop (i dont...

I definitely understand and agree oiling properly is important, but beyond stock and getting into performance mods I am pretty lost ��. Luckily this isn't a daily driver, won't see much offroading unless you consider dirt roads and utility roads offroading. Mostly 55mph highways...

I guess I know what I'll be doing to the engine next! Thank you so much for your help and advice!

I dont think that if it is still leaking it's that bad of a leak, so I'd say question is answered! It's just been wet underneath, blowing back along the tranny pan and mount. Also don't drive it far, but haven't noticed oil level dropping in the 2k miles we put on it since getting it (likely...

Thank you again! I was thinking about heavier oil, but was hoping something as simple as a pump would potentially be a proper fix... I did notice oil at the bottom of the bellhousing before replacing the head, but the head gasket has been replaced before (had a victor reinz gasket, and the...

Thank you for the reply! I am running 10w30, currently cheap stp conventional high mileage for the flush but typically run full synthetic. I have read mixed things on the high volume pumps, although I have been leaning towards one anyways for a similar price to stock flow. I plan on pulling a...

Hi, everyone! I have been reading along, found answers go most of my questions except this one... First some info: I have a 1999 2 door cherokee xj 4.0 auto. I know very little about the history, other than gaskets were changed, Thermostat replaced after sticking closed. Heater core was...
