My '89 YJ hates me lately. Help!

Serpentine belts... oil leaks...bad sending unit? Ahh!
I've gone through three serpentine belts in the past month... and my current belt is being torn to shreds. This is AFTER I had a professional mechanic install the serpentine belt and my boyfriend aligned all my pulleys to ensure my Jeep wouldn't eat another belt. I can't figure out what's going on. My only guess would be that my alternator is an aftermarket alternator and has a 5 rib pulley instead of 6 rib like all my other pulleys. Could this be a possibility? I have a pretty expensive, pretty beefy alternator and don't want to get rid of it if that's the cause. Could I just replace the pulley? It's a Powermaster alternator. Not sure on the exact model.

As for the oil leak... I thought it was the gasket on my oil pan. Actually, I was pretty sure the old gasket was the cause of the leak. After replacing the gasket, I'm leaking oil about the same as I did before, maybe even worse. We ran a couple beads of silicone around the gasket and tightened the bolts to the correct torque.
The funny thing is, my Jeep only seems to leak in the parking lot at work, not at my house. Last night when I got home, I put an old white rug under my Jeep to see if it leaked at all. I had one drop, smaller than a dime. At work, I had a significant size puddle. The strange thing is, my oil level has stayed about the same. It may have dwindled a teeny, tiny bit, but not enough to say so or justify the puddle. Any ideas???

Also! Before the gasket/oil/filter were changed, for the first time ever, my Jeep was burning oil. BAD. Now, it barely even smells of oil when driving/idling. I did do a really deep clean of my engine bay-- even broke out the degreaser. When changing the oil filter, it appeared as though it hasn't ever been changed. So I think the new one has definitely helped.

I do not believe that I'm leaking any coolant, and my Jeep hasn't overheated. Brand new thermostat in it.

Sorry for rambling... but I really would like to figure out what's up with the leakage and serpentine belts.

Vehicle details: '89 YJ that originally had a 2.5 4 banger in it. Engine was swapped out for a 4.2 I6; complete engine rebuild about 22K ago. Runs like a champ, aside from the recent issues that have developed.

I'd appreciate any helps or tips that I can get. Thank you!

Oh! Also. My oil pressure guage is spastic. I think it's a bad sending unit, but I have no clue.

Big list of issues, I will start with the belt.

If you do not have the same pulley type on your new alternator, this will stress your belt and cause issues. In this case, it sounds as if you have forced a 6 rib belt to ride on a 5 rib pulley, this will act exactly like a misalignment and will cause your belt to walk back and forth across the pulley and overheat / eat itself. You should be able to get a replacement alt. pulley.

As for the burning oil / leaking oil / spastic gauge. It sounds like a faulty relief valve on the pump. The first thing to do would be to put a mechanical gauge in the port that the sender connects to, and watch the mech. gauge and see if it mimics what your factory gauge was doing...if it does, you need a new oil pump assembly, if it doesn't then you should replace the sending unit.

As for burning oil, that could be related to sludged up oil passages creating back pressure that resulted in oil being pushed past the valve seals, or the oil had been broken down so much that is was getting past the rings? The real test of whether you are burning oil would be to look at your plugs.

Leaking is a different issue, you need to know where the leak is coming from to get advice, but I would work with your potential over pressure issue first, a broken relief valve can cause lots of leaks where there otherwise wouldn't be leaks.

i would take a real good look at the valve cover gasket far a leak, they are real bad to leak and the oil get blown back and run down the bell housing a cause it to look like the pan or the rear main seal are leaking, the oil sending units are also bad to go out and give a bad reading, plus leak oil and it blow down and back and look like you have a leak farther back and lower tha where it is coming from. the oil you smelled burning may have just from where it had leaked out before you cleaned it and changed the oil and filter, i'd start with the sending unit and then clean it real good and look higher on the engine for the leaks, hope this helps.

Okay, so, I'm an idiot and kind of a newbie to fixing my own vehicle.
To check the valve cover gasket thing, I'd need to remove the valve cover, right?
Should I also drain the oil? Or will it be okay?

Don't ridicule me- I'm trying to learn.

Yes, remove the valve cover. When the engine isn't running, the oil goes to the crank case (lower part of the engine) so no need to drain oil to remove valve cover.

Okay, cool. Thank you for the advice! I appreciate it.
