Speaking of oil filter adapter o-rings, is this the correct part number MOPAR 4720363? It shows for 00-01. The adapter was different before this? This is the only part number I've found for the full set of 3.
Also, is Crown Automotive stuff good (same part number)? I've always seen them, but never bought that brand.

Can anyone explain, describe, or show pictures of how an APN header does not fit on a 99 properly?
I just finished replacing my head gasket and I'm having an issue with the intake/exhaust manifold area making a huge hissing noise. I checked most of the bolts and they were snug. The intake slipped on perfectly and isnt sitting funky or anything. Its all flush. When i read about the issue with 99s it was that the intake wouldnt seat properly. I just want to make sure my issue isn't from the APN.

Not exactly your model year, but you can grab the '99 FSM here: http://cruiser54.com/?page_id=365
All the dealer tech troubleshooting and wiring diagrams you could possibly eat are inside.
If 42 lbs. residual is enough pressure to start, I guess I'm chasing spark. I used to have one of those lights, looks like I might need another. So, I take the coil rail off to expose the plugs and test from there to the plug tip? Sounds awkward but I'll give it a shot. I have to pull the rail to check plugs anyway, I found the meter test proceedure for the coils also. I'm going to test the tps today, found a good clear thread on that, then start looking for crank/cam sensor test threads. I really don't want to start replacing things, the crank sensor looks like it'll really be a pita to change without being pretty sure it's bad first. I need to get under there with a mirror anyway to check the harnesses for rat damage, not unheard of around here.
I have an OBD scanner, it pulled an old #3 misfire code (from heat sink problem) I erased that and it didn't come up with anything new, so I'm pretty sure it's working. The guy I got the jeep from seems to take good care of his rides, lots of new stuff on it and everything working great till now. Fuses and relays are the first thing I checked, I just put a sub under the seat before it decided it wasn't going to start, I backtracked and disconnected all that thinking I might have shorted something and blew a fuse

Also, if the ASD relay isn't energized (you can tell if this is working properly by checking for 12V at the fuel injectors), there's a fatal CKP/CMP problem.
0.5" last time I looked at Moog's site. Handy for lifted XJs.
