Somehow, miraculously, I managed NOT to dick up the timing while doing this. This is my last oil leak on this rig. Fingers crossed!

Edit: I did manage to dick up the timing. Hope it doesn't blow me up on my way to and from work tomorrow until I have the time to pull her apart again and find TDC...


Replaced the distributor gasket with a Fel Pro one. OEM gasket was determined to be razor bladed off and was hard as a rock. My 98 came with the above adapter for the bunny ears it looks like. Pretty sure I know what factory tight feels like at least.

Forget HP... Torque brother... torque...

We really did do ourselves a disservice when we went from small bore long stroke to short stroke large bore. If we want to fix the mess we need to go back...

I have a 1950 BSA pre-unit to prove this concept. I can idle up to the bottom of a hill in fourth gear and then accelerate to the top without needing to shift down at all. To this day they still dominate hillclimbing because of the small bore long stroke torque.

Sorry, yeah, I should've typed "torque" and not power, as that's conflated with BHP, which I don't really care about for a Jeep powerhouse. My mechanic neighbor said the only way he'd get a Jeep is if he had an LS to put in it :| oh well, nobody's perfect.

Oh no man... You are good. Thing is as a society we got wrangled into the "AMA HP" rating at xxxx RPMS. Drag racing RPM's was such a huge factor in that. Truth is long stroke torque when geared properly kicks HP in the you know what. We would not have emissions issues, or mileage issues, or power issues if we had stayed with long stroke small bore engines. The model "T" got about 30 miles to the gallon. Now just imagine if it was fuel injected and computer managed? An average of 50 MPG or more at 80 is not too far fetched as a reality, even more if it is a diesel.

thanks man finally got it to throw a code driving around to day and its po758 shift solenoid b

i ordered a set of solenoids over the weekend along with a gallon of trans fluid, pressure control solenoid, and a filter filter/gasket set for the 4l65e after some googling they should be here tomorrow

on the lighter side of the news i finally got it all the way back together today after work since my new trans cooler came in.

and drove it a little bit just manually shifting gears around the neighborhood. did good, it feels so alien to me now not having driven it in a year or so

Went and bought it and brought it home. That counts as doing something, right?

Honestly, they make the same power as a 4.0, just better on fuel and all mechanical, so no electronics to worry about.

As for what I did today, cut the oil sump to clear the steering linkage once swapped.

Been a couple days since I did it, but I forgot I had gotten a wj brake booster for my Comanche. Some posts I see say you need a spacer and some posts I see say the reason to use a wj booster is so you don't need a spacer. So does anyone know the answer?

Sorry, I can't answer that as I don't have power brakes on my MJ.

Nice. It was a snap to replace those solenoids, just make sure you're putting the right one in. There are a myriad of stickies available for this, if I recall correctly. Perfect timing with the fluid as you have to remove the tranny pan for access to do this. I'm sure it won't take you long.

Installed an Artec Industries Front Axle Replacement so I can put in a 1/2" Johnny Joint.

Turns out I'm terrible at welding. I'm not super happy about it, but I'm trying to get this done before it snows. Unfortunately it's going to have to work as-is.




I lined up a laser level with the factory bracket, then used it to correctly center the new one. At least it's on there straight!

The 86 needs one of everything, as in it's just a somewhat rolling chassis, well, with a squished box from a tree falling on it which makes it look totally bent.

This one might be getting built up to replace the 88 as DD duties, since it looks like it actually could be made at least somewhat nice.

Well back to the drawing board, none of the XJ's had heated seats so no switches. So it's either fabricate a new panel for different switches or just do away with them. Or does anyone have a set laying around? They are discontinued from Mopar.
