oil

I did it!!! I found my coolant leak!! Very exciting as a novice mechanic 😄 This radiator hose was very pregnant. So I’ll replace it tomorrow. But I still have questions. The leak was pretty slow. Lost 1psi about every 1-2 min and it slowed to a stop around 15 psi. She’s not leaking while...

I just bought some gear oil for my differentials it’s 75-140 with limited slip additives in it. I don’t have a limited slip I just have stock rubicon axles with air lockers. Is it a okay to put it in the diffs,, is it going to do damage to the air lockers or the differentials? Should I return...

See attached pictures. Recently changed the oil myself for the first time ever. Noticed a little drip (blue circle) every so often. Full disclosure I did spill a small amount of oil on top when filling it. I also used what Autozone advertised as conventional motor oil but as I was filling the...

So I have a friend who I'm trying to help out. So far I've replaced the oil pressure sender, but I don't believe that's the issue for as the single wire going into the white connector, not the black connector at the PCM. The black connector is where the oil is. The gray and white connectors are...

Howdy all, I've been having some ongoing issues with my TJ. Hoping someone can lead me in the right direction with solving the problems. First I had a loud chirp/squeak coming from the engine. Discovered there was a rocker arm that was dry and rusted. Changed that pair of rocker arms and...

I changed my oil roughly 2000 miles ago and I recently checked my oil and found that I was 1.5 qts low. I have had trouble with oil leaks from the valve cover gasket so I replaced it, and it seems to be holding up ok, I think. Since replacing the valve cover gasket and cleaning the valve cover I...

I'm upgrading my rear diff cover so I need to buy some gear oil. I have been reading through the forum and have decided I will go with a non-synthetic oil. Just wanting some recommendations on what weight to get I don't tow but I live in Colorado so the winter temps can get very cold. Secondly I...

I have a 1997 with a 2.5 and a manual trans. So I got back from a 30 minute drive averaging probably 55mph. I walk around the back corner of my Jeep and there’s a milky brown substance splattered on the quarter panel and fender flare under the gas filler. It appears to be milky oil (like when...

So i ended up pulling the oil pan off of my 97 4.0 to try and figure out what was causing a knock. well ended up being the #3 piston skit was found in the oil pan. I found a used 4.0 out of a 97 Cherokee to do a engine swap with, but i wanted to clean up and put some new gaskets in the "new"...

My 03 Jeep Wrangler has been leaking a bit of oil the past few days. (At least I think it is oil). But it seems that it is coming from the Manual Transmission Vent behind the Oil pan. I want to change my oil but am holding off until I can find out what this is coming from. Would anyone be able...

Okay so I think I know what this is and how to fix it but before I do I wanted to hear your opinions. 2004 Jeep TJ Sahara 4x4. Automatic Oil pressure sits perfect while Rpms are higher than nuetral. But once I place the Jew in park OR I’m in drive and sitting at a red light my oil pressure...

Hello all, That title wasn't phrased very well, but in essence I'm trying to figure out what part(s) I need to replace for my leaking transmission oil system. The leak is happening right at the side of the oil tank below the radiator. This is the only picture I have on hand right now: It's...

I went out and purchased my first tj a little over a month ago and the oil pressure gauge just started to act up. I put a new sending unit and harness in it and the oil pressure gauge still doesnt work. It will read 40 psi then just randomly drop to 0. I know I have oil pressure because I hooked...

My 05 TJ Rubicon has been using 2 quarts to a quart and a half every 3000 miles with it being winter in Iowa I've been running 5w30 jeep and just switched back to 10w30 today. It only has 103,xxx miles no burning out the pipe or anything noticeable leaking either. I know some vehicles have oil...

Sooo every time I start my tj the oil pressure does not read at all, I shut her down and restart and it registers normal. This is how it goes every time without fail. I changed the sending unit so now I'm wondering if its the guage.

I HAVE 2003 WRANGLER X. JUST CHECKING FOR INFO FOR THE TYPE OIL TO USE. BOUGHT JEEP AND HAS NO OWNER MANUAL..... THANK FOR ANY HELP JANET

The subject of oil filters, like conventional vs. synthetic oil, is an emotional subject for many. I have to admit that over the past 10-15 years, I was caught up in the oil filter debates and formed some very strong opinions… particularly about Fram’s oil filters. Based on what I had seen...

These instructions are not meant to replace anything that a service manual or owner's manual requires you to do. I occasionally get an e-mail, or a posting appears on a forum, concerning how to change differential fluid. This is necessary maintenance for anyone that 4 wheels on a regular...

This article was originally found on stu-offroad.com. For some folks, this write-up may be extremely basic. However, the goal here is to educate all levels of Wrangler owners. I don't know about the rest of you, but I learned how to do this years ago as a kid, growing up on a farm. While I...
