All: see the picture. It has ran like this for years, but is there any solution to make the oil cap tighten down?

I've got a 2.5 motor seems very strong doesn't use any oil and is always clean at oil change but the oil pressure is low after I run it a while water temp is consistent at 185 new radiator and stat any thoughts from the crowd ???

So I recently got myself a project, a 93 YJ, 4.0L, 5 speed swapped and just needed a few switches to be done. Replaced the turn signal switch and brake light switch but after fishing the turn signal switch wire through the steering column, it no longer starts. I get power when I put the key to accessory mode (dash lights, fuel pump primes) but when I turn it all the way to start it, no click, no crank, nothing. Battery is checked and is all good, starter wiring is good.

Curious if I could've damaged the ignition with the wire or something, I don't really know, I'm used to xjs so it's a little different.

Whats up everyone. I am new to jeeps I purchased an 89 yj and one of the first things I did was put 2.5 suspension. I put transfer case drop to stop the vibration, like alot of videos and comments say, but now 2nd gear pops out or wont even go in at times. What do I need to do next to get it shifting in 2nd properly again? 1st 3rd 4th 5th and reverse have no problems at all. Thank you in advance!

Having fuel pressure issues, I know fuel pressure is suppose to be around 40psi when the vehicle is running on a 4.0L, but what about when the vehicle is off, I'm trying to troubleshoot a fuel pressure issue, can anyone hook up a gauge to the rail and jumper the fuel pump relay to see what it reads while the vehicle is off, mine reads 65psi, don't know if thats right

I love my 95’ YJ, but hate hate hate the ride of the leafsprings. I know it’s been done numerous times, so coming here to ask what brands/kits people have used to swap their YJ from leafs to coils and how much did it cost you?

My 4.0 is somehow missing the idler pulley, which explains my trouble setting the belt tension. I have power steering but no A/C.

Can someone upload a picture of their idler pulley? Bonus points to anyone who can tell me the bolt size for the idler. I don't know if I am missing some sort of bracketry in order to install the pulley. Can't find any part numbers online as far as what I may be missing aside from the pulley itself.

Haven't had problems with her starting, until today. I started her up, she started, realized I needed something from the house, shut her off. Got it within 20 secs and she doesn't want to start back up. What should I checked first?

Found an 88 YJ for sale, it needs everything but a clean title. Found a 92 YJ that has everything but interior and a clean title. Thinking of buying both and taking everything off the 92 for the 88 and buying all new interior. Any advice before I make my decision?

Bought this project a couple weeks ago and haven’t explored what this might go to. Anyone have any ideas? It’s sitting under the drivers seat.

Are there two different shapes of wrangler yj model?

I'm having problems with my yj. When I start it it wants to backfire and when I push on gas pedal it does the opposite of what it's suppose to do Instead of accelerating when pushed it boggs down and when you let off gas then it wants to accelerate but then backfires??

I have a 90 YJ that was lifted in 92 ( I did the lift myself back then) with good ole early 90's leaf spring tech and yes it rides stiff . . . does removing the track bars really make enough difference to mess with or should I just upgrade to 21st century spring tech 🤷🤷🤷🤷

My daily driver got new rear brakes installed a month ago, and about a week later, the YJ started groaning when I put it in gear to park it.

I will come to a full stop, cut the engine off, put it in gear, then as the Jeep settles, I’ll hear a groan that sounds like it’s coming from the rear wheels. It will also groan when I hop in to drive it home and take it out of gear, which allows it to roll a little on our uneven dirt parking lot at work.

I took it back to the brake shop, and they said this is a drive line issue. A couple mechanic friends said it sounded more like the brakes were installed a bit too tightly.

Anyone else have this issue or any knowledge about drive lines? The nearest shop that will look at it is 100 miles away, and I’d need to leave it there for a few days, so I’d rather not waste the trip if it’s just my brakes guys passing the buck.

So we got a clutch kit from AutoZone for 90 YJ 2.5 L and put it all together and we failed to look at the trigger ring on the new flywheel to see if it matched up for the crank sensor…now it won’t crank because the new flywheel doesn’t have all the teeth in the trigger ring…. is there anything short of dropping the transmission back out that can be done to make the vehicle run? Because right now it looks like we just got to drop it back out and put the old flywheel back in… not really trying to tho

Anyone ever run the oem xj wheels on their yj? I found a set, debating running them with some 31x10.50s

I start running my YJ topless as soon as the weather warms up, but spring storms lead to wet seats and I’m hitting a dead end for seat covers. What are you all running for waterproof, well fitting covers? Looks aren’t as important as truly waterproof and fitted well enough to not slip around and not flap in the wind.

Was browsing FB marketplace, and got an ad for some current auctions happening. And this one caught my eye...till I saw the current high bid (with a day left). Who is bidding on a '91 that lived a hard working life, and with lots of rust spots??!

Anyone know what diff (gear lube) fluid I should use for the dana 35 and 30?

Having a hard time finding decent front seat covers. Would like something Black. Heavy duty maybe Faux Leather for the stock high back seats. Any suggestions?

I know it would just be easier to install posi-lock or delete the CAD entirely, but I'd prefer to keep my YJ stock.

I've checked, and I have vacuum at the actuator. The vacuum switches when 4WD is engaged as it should as well. I assume it's the actuator, though I haven't opened up the axle yet to see if anything is stuck yet. I'd like to check and make sure that I'm getting the appropriate amount of vacuum at the actuator, but I can't find what the PSI should be listed anywhere. Does anyone know either what the pressure is supposed to be or what is a general psi for the vacuum?

I use my 1992 Jeep yj 4 cylinder as a daily driver and my off-road. I sometimes have to speed up fast to keep up with on coming traffic and it does okay depending how fast people are going.

I am wanting to make my Jeep speed up faster. Do I need a super charger or is there a cheaper option. Im planning on getting a cold air intake and a cat back exhaust. Obviously those are pretty small things but is there anything else I can do besides a engine swap?

(I also just got this guy three weeks ago so excuse the dirty engine bay please)

Thanks
