Hey fellow Colorado XJers. It’s time my 4.0 got some serious TLC and some beefing up. I’ve had my 90 Laredo since 1994. It’s built up nicely for exploring the Colorado trails. However, the 4.0 is tired and stressed pulling all the extra weight of larger tires and armor, especially over the...

Darn, I had hoped it would be so! Thanks for letting me know.

I did! Just unfamiliarity with the old ports, actually. Didn't know the old ones had to be opened/used also in order to allow flow. I did not do the filling myself and wish I had asked for the pressure numbers. They just told me it took a charge "as designed". Now I have to troubleshoot what...

Searched, but just couldn't find... Is it possible to replace the AC low pressure switch on a 4.0 Renix ('90 Laredo) without purging the R134 (converted from R12 years ago)? Just had the system re-filled after not using the AC for years. Clutch not engaging on compressor (it will when I send...

You guys are awesome. I’ll check those out. Thanks!!

Part of R134 conversion used to charge the system. Seems it lost the ball valve. Thanks for the help! Sent from my iPhone using Tapatalk

Has anyone installed BW 4dr cutout flares recently (purchased since July)? The latest install instructions (Rev J; June 5, 2006) are MUCH more detailed than previous versions and include a lot of photos. You can see them in color on their website for better clarity, as well. Have these new...

How about in the Colo Springs or Castle Rock area? Any good junkyards around there fro XJ parts? I have a lot of nagging trim and other low-priority parts that I don't feel like paying "new" prices for - especially since the trails will usually do their thing to them again!

I wish it were as simple as the PCV (good idea, but I checked that already) or the sender unit (it looks clean in 360 deg). That's why my last guess has been the pressure sender unit - I can't see that readily - now that I know it's in the oil pump. I'm bringing it in Monday and want to point...

My oil pressure sending unit looks good. Actually had that swapped out last year. I think it's the only "clean" thing left in there! All the oil found is below that point. Thanks for the info guys. I'll keep trying. Know a good place to get a good H.O. cheap?

Anybody know where the oil pressure relief valve is located on a 1990 4.0L? I've got a lot of oil coming out, the oil pressure guage is reading high and I've already replace the valve cover gasket, main seal, and the oil filter o-rings. My last guess it the pressure relief valve, but I can;t...

I have a 90 Laredo with 169000 miles on it that needs some engine attention (dripping oil, overheating, poor starting) before I begin modifying it (hence the name "BoneStock"). Anybody know a good place in the Springs (preferably north) that does good work? I just moved to the area and assumed...
