  1. oil in my coolant

    JK Tech Forum
    I recently found oil in my coolant but no coolant in my oil (yet) so my best guess is that it’s a blown head gasket. With having 190,000 miles on her I think it’s wiser to replace the engine instead of just the head so I have one on order. I’m going to drive Daisy until the engine arrives so I...

  3. Oil leaks

    YJ Tech Forum
    Noticed this after going for a short drive. What am I looking at here? engine oil/transfer case leak? how serious is this and how easy/difficult is it to fix? I marked the spots where I can see the oil dripping from.
  4. Oil is mixing with coolant! Radiator is gummed up as well as heater core

    TJ Tech Forum
    Man do I have a mess. I bought this 1998 TJ with a 2.5L in it. It ran good for about 6 months. When I bough it the oil pressure when at a stop would drop to close to zero. I changed the oil and put Rosella in it and it held for about 200 miles then started doing it again. The heat also went...
  5. Tiny metal pieces in Transmission oil during change

    JK Tech Forum
    JKU 2013 auto transmission( W5A580) with 53k miles. Since it was due, decided to do a driveway transmission drain and refill, along with filter change. Got about 5.5 liters (5.8 qts) of old oil out of the tranny. To my dismay saw a lot of tiny metal pieces in the pan. Pls zoom into the attached...
  6. Oil Pressure Fluctuations

    TJ Tech Forum
    Trying to get better at working on my own stuff and had a question on my 1997 TJ 4.0L. Is it typical for the oil pressure to read between 20-40 psi and just randomly fall to 5-35 psi and then return to the normal 20-40 again? A little history: Not mechanically inclined. Trying to do more...

    Hello- New Wrangler Forum user here! I'm currently driving a 2009 Jeep Wrangler Unlimited Rubicon 3.8 L V6.

    So, after much debate and research on how to recondition my bumpers, trim and side steps I FINALLY DID IT!!! I was so tired of looking at grayed out bumpers and trim I finally decided to go ahead with applying Unrefined Coconut oil!!! Not the liquid kind, but the kind that looks like Crisco. You...

  10. Slighty Higher Oil Pressure

    TJ Tech Forum
    I've searched high and low for anyone having a similar issue. This has been going on for 2 oil-changes. All I come across is one of the two extremes, super low/high, no awkward slightly higher than normal. It's an odd angle, but this is what my electronic sensor reads out. Just a couple...
  11. Amsoil 5W-20?

    JK Tech Forum
    I've been running Pennzoil Ultra Platinum synthetic 5W-20 since new, and am just about at 45k mi, so due for another oil change. Reading through some threads here, some folks have reported switching to Amsoil 5W-30 quieted down the typical startup clatter/valvetrain noise on the 3.6. Looking...
  12. Ok, that sucks!

    JK General Discussion Forum
    I just changed the oil on my Rubi, and after cleaning up I discovered that the rubber gasket from the oilpan plug had came off and was in my used oil pan. I never even noticed it was gone when I put the bolt/plug back in. It's not leaking, yet, but I guess I'll be draining it again tonight. :(
  13. TJ 97 w Dana 30 and 35 oil levels

    TJ Tech Forum
    Hi, I've recently purchased a 97 2.5 Jeep and I'm going through it to ensure things are in good order. There's a small oil leak on the rear pinion seal, so I will change it in the very near future, but I wanted to check the oil level meanwhile to make sure I wont damage anything before I get to...
  14. 2012 JKU Oil smells like gas

    JK Tech Forum
    So my Jeep was due for an oil change and last night I decided to do it. Once I removed the oil filter there was a strong Gas smell coming out of it. I tried to google it but cold not find any cases of 3.6L engines with gas smelling oil. I've had the Jeep for 2 years and there was no smell...
  15. Metal Flakes / Particles in Oil 2013 JKU 3.6 50K

    JK Tech Forum
    So... the last time I changed the oil, about 4,300 miles ago, I noticed metal flakes in the drain pan. I figured they were from one of my lawn mowers. But, when I changed the oil yesterday, I cleaned the plastic drain tub very well so I would be able to tell if there were any metal flakes from...
  16. 2007 Wrangler / 3.8L excessive oil consumption

    Connecticut Jeep Forum
    I bought a new Jeep 2007 Wrangler Unlimited Sahara a few years ago. I live in Fairfield, CT. I went to SCAP Auto, in town. The car was fine for a couple years until we started noticing the oil consumption was unusually high. We’d get it changed here and there and time went by. I started a job...

  19. Blackstone Labs Oil Test

    JK Tech Forum
    It's about time to change my oil so I ordered a kit. I don't expect to hear anything bad, I'm just curious what it would say. Being a 3.8L, I wonder if they are able to tell if mine will start burning oil soon? Has anybody done an oil test on their JK? If so, what did they say?
