cold start psi is 40-45 psi

I recently had the cylinder head replaced and oil now seems clear. I recently purchased the jeep and with the head replacement and other stuff I already spent 2k on a jeep I spent 3600 on. I'm ready to throw the towel in. I will likely take a hit in selling it and may leave it to the next owner...

ok so today I changed the oil. I used a Napa gold filter and 6qts of 15w40 Rotella, I noticed no increase in oil pressure and I believe the engine now sounds louder more clanking sound. I was really hoping the 15w40 weight would boost the psi a bit. Still seeing 10psi at warm Idle and 20psi...

jeep has 136k. I only had it 3 weeks so .... I may go with a 10w40 grade and a Napa filter as recommended by muddymike. As for oil, should I good with synthetic or just a standard brand like rotella, mobil1 or valvoline? Is one any better to keep my oil pressure running higher?

Garr - Currently 10W30 with a Purolator Standard filter. Being in NY and temps can get into the teens sometimes, I',m thinking of going with 10W40, filter wise any suggestions?

So... I bought a 2000 Jeep Cherokee 4.0 and the next day I found it had a crack cylinder head. I had the cylinder head replaced and I am worry about the oil pressure reading Cold start it's 40+ psi Warm idle after 30 minutes just at 10 psi Cruising at 45-60 at 1500-2000 rpms around 20psi...

I am now waiting for the replacement head from Clearwater (should arrive tomorrow) In the meantime, I changed the oil and flter and started her up - oil pressure is up above 40 and I (not being a mechanic) noticed no knocking sounds. So I will leave it as is until the part shows up. Base on...

So .. here's my plan. I ordered a Clearwater cylinder head ($475) and was quote $550 by my mechanic to replace the head. By the time it's all done the damage should be around $1200. As I just purchased the Jeep and have no history on how the PO handled the issue, I do feel like I am taking a...

OK... so as we expected, the mechanic who preinspected the Jeep is claiming no accountability. Sounds like a home inspector... "I can't see pass the walls to know there was a cracked cylinder head". Of course he is willing to give me a quote to repair the head and claims he is giving me a...

HI All, So I am planning to replace my cylinder head on a 2000 Jeep 4.0 Cherokee Sport. Alabama is out of stock (4-5 week wait) but Clearwater has them in stock ($599). Reading through the forum, seems I should be ok with going with Clearwater (please let me know otherwise or what to look...

Alaskan89 Thanks for your helpful input. As much as I would like to take this on as a project with my son. Unfortunately, I have no mechanical background and probably lack some of the required tools to take on the challenge on myself. Guess I could change all that, buy the manual and tools...

Appreciate the link... read through it a few times. So here's my main question... are most folks finding replacing the cylinder head works out ok for them? I have no history on how long the previous owner had the issue. But when I drove it home the day I purchased it, it ran like a top with...

Forgot to mention we found it had no thermostat - hence the low temperature.

So here's some additional information on my situation. As I mentioned I had the car inspected by a mechanic but... 1) 2 days later my son complained it was not getting much heat and I noticed the temp wasn't getting much above 165. 2) So I brought it to my mechanic and he flushe the entire...

We've been searching for a Cherokee to be my son's first truck. We found a clean 00' Cherokee sport (136K) and had it inspected by a mechanic (not my mechanic car was not purchased local) and now (3 days later) found it to have a crack clyinder head (which I had learned about this sooner to be...
