Nice write up. Fuel lines are on my list soon. Working on brake line’s now.
Did you find the fuel lines that go from the fuel rails to the frame. If so do you have part numbers and where they can be bought. My went south lost all most a haft tank of gas when it blew. I just not having any luck finding or is there a way to repair or replace the crimp on rubber line that give flex between the frame and engine. Any help will definitely be appreciated.Nice write up.

Yeah, that is what I replaced in my last post. All those photos are those lines, from the fuel rail to the hard lines down on the frame. The rubber was in very bad shape and I was worried about a pressurized leak spraying fuel on the exhaust header and causing a fire.Did you find the fuel lines that go from the fuel rails to the frame.

Yeah, worked pretty well. Easy job overall, just a pain getting the bracket back in place with the new lines. Happy to finally get this one off the list and not be worried about the Jeep burning down from those old lines.Glad to see they worked! I’ll grab some if mine ever start to look bad. 82K miles and still seem solid but I haven’t really looked close. Probably should.
PlasticFury - would you say that SEM Trim paint is a flat finish or a satin finish. I am trying to paint some factory side molding steps to match the new replacement front and rear fender trim.
The Jeep only has 61k on it and the engine was running and sounded pretty good but was leaking oil all over. I started to go through the engine, the valve cover bolts were all finger loose and two were missing in the back. This whole thing turned into "while you are in there" pretty fast. I had already been planning to replace the valve cover and oil pan gaskets, most likely the rear main, water pump, thermostat, all the usual stuff when no maintenance has been done. The engine mounts were shot and I swapped in the Brown Dog mounts I had in my previous YJ (should have waited to do that a little later lol).
I started tearing all the accessories off the engine. It was one caked, oily mess.

While I was cleaning all up the block/head I was gently using a wire brush on the core plugs

The next morning I had a little puddle on the garage floor. I realized the plugs must be pretty rusty on the inside. Great. I drained the coolant and found that the PO had been using tap water for coolant. I flushed it several times to try and get the crappy, rust water out.

Yeah, just what I wanted to see.......

I was actually glad that it leaked through one of the plugs, I may not have realized how bad they were until I had put everything back together. Much easier to replace them with it torn down.

Wow, I've always wanted to take my manifold off and see what the block holes look like after 35 years. Probably like yours with a big carbon deposit around them! Does the engine breathe better or feel/run better once you've cleaned them and opened the holes up to original sizes?
I can't say honestly, I only test drove it around the property and then on to the trailer and off the trailer into my garage before I started tearing it apart. I can say it runs awesome currently after I went through everything and rebuilt it. The intake manifold was a real mess of caked oil and crap. The ports weren't much better and I cleaned them out as well. Worth the effort for sure as it looked like it hadn't had any real maintenance in a very long time.

Dumb question time but am i right in assuming if the ports and inlets are partially clogged or caked in oil and carbon build up, then scraping all that out and cleaning them up will allow the ole jeep to -'breathe' better and perhaps run a little better? I do t mean incredible performance improvements but perhaps a smoother more efficient run?
Cleaning out the intake and the intake ports would certainly not hurt anything. As I was going through everything, I was cleaning out everything I could. I also cleaned and polished the throttle body. If you are having issues, it's probably in another area but if you are planning to do some deep diving on maintenance, it would be good to do. The throttle on mine was very oily and nasty so I knew it was a mess in the intake. I also replaced the pcv valve, grommets and the tubing. Not to mention all of the other maintenance I did while tearing it all apart, to include the K-suspension 4 hole fuel injectors.
Nice one. OK. I'll plan on doing that. To be fair my TB is spotless, really clean so perhaps the intakes are not too bad but I'll be looking at them anyway when I replace the intake manifold gasket which certainly looks like its seen much better days!
Definitely. If you are planning to replace the gasket anyway, then why not check it all out. See how clean your intake is, it could just be oily or it could be really caked up with oil like mine was. The back of the TB was really nasty as well. If you are going to have it all off anyway, that is the best time lol.
Yeah, it's going to happen. The Jeep is still at the 3rd mechanic. He's trying everything he knows to get it running again. If he does and it can be trusted to keep running, then over winter I'll be whipping the manifold off and changing that gasket and I'll be scraping and polishing the ports as recommended! I'll be taking pictures as I go along for any other 2.5 TBI 1989 owners whom like me are having to teach themselves everything about these old timers!
I assume you mean cleaning when you say polish, no need to polish any of the ports, it's basically a farm tractor engine lol. Just clean them up as best as you can and make sure if you are not removing the head that you put something in the ports to stop debris from getting down into the cylinders. A good tooth brush and some cleaner will work well. On the intake, I pressure washed it first, into all the ports and on the outside. Then a little degreaser and a brush to get what I missed.
