Crawling under my 94 fzj80 tonight and saw this. A little help would be appreciated. Background first, got my fathers LC off his hands finally. He never drove it so Im the proud owner now. Only has 87k on the odo. It sat a lot when he had it. Anyways, looking to see what's going on underneath.

Rear arch seal maybe? Might be disguised as a power steering leak. Mine looked like that when I got it and 99% of all the crud down there was from the ps lines.

Factory undercoating

Seriously though, check all the rubber lines in the area. They are old and tired and probably leak a little.

Valve cover gasket is another culprit. It is best to degrease everything and start with a clean slate to find the root cause.

Pull it on street or in yard and hit it with a few cans of Brake Cleaner. Make sure you wear safety glasses, gloves, and junk clothes.
It's a total guess till you know source.

Valve cover seals leak and drip down the side of the motor.

Here she is! Last week she got new 285/75 duratracs, and fedex dropped off my order from Slee, a stock height replacement kit. Wanted to keep her pretty much stock as its cherry! Cheers.

You can get it steam cleaned for about $80 and often comes with a complete vehicle wash. No brainer and will get it far cleaner than you will with 10 cans of engine cleaner etc. Plus you don't get dirty! Besides making it much easier to find the leak it makes repairing the leak so much nicer.

Just had my sons new engine bay done, I would have paid $100 bucks not to deal with it!

Another vote for hitting that with a hotsie or at the very least, run a garden hose off your hot water heater & use some degreaser you let soak awhile - you have some 20 yrs of accumulated grime, so start fresh to see where you have minor leaks. You may have nothing worth changing parts over, if it's never seen the steam cleaner or degreaser before.


Attaboy keeping with the stock lift parts (heck, bet the OE springs are still worth keeping - I'd pick 'em up to toss on my 40th - so don't toss 'em!

Also, attaboy not going nuts & making a Moab machine out of this - let that happen to the higher miled rigs. If it was mine I'd leave well enough alone too!

Keep that clean, garaged if possible - and I bet you'll sell it someday for a whole lot more than alot of our modded & beaten 80's. Yours is worth keeping nice, and keeping your records - was Dad the original buyer?

You have a honey of an 80, don't let anyone tell you otherwise - that's too nice to convert to a rock runner (blessing and a curse)!
