Sorry. I’ve got no idea where it’s located. Seem pictures of it on line but no videos or write ups. Sent from my iPhone using Tapatalk Pro

I thought it was after 2007 addition, but I have heard of some early 3.7 that did have egr, one was a low mileage motor I think the guy said was from Mexico. I’m just not sure the early liberty 3.7 had them or not. Sent from my iPhone using Tapatalk Pro

If you have a EGR valve standing in front facing the engine it will be to the right hand side at the top rear of the engine. Sort of behind the where the intake is, it’ll have small piping that goes back to the intake if I remember right. It is held on by two bolts and has a wire plug...

If the pcv were clogged it could cause leaks in unusual places, not sure about the 3.7. On other engines I know clogged pcv can creat a situation where oil leaks happen at the rear main, but these were much older engine. IMO nobody wants to say go on a big job like this because With these...

could it be blow back from leaking CCV? Crank case ventilation. Sent from my iPhone using Tapatalk Pro

Is there any noise coming from the engine when the light is on? If not it’s probably just a bad sensor. Sent from my iPhone using Tapatalk Pro

Update on that Commander Transmission, well it's kaput. It was still shifting smoothly, but I think the pump has started to fail. Dropped the pan today, fluid was off color, only a year old with maybe 20k driven since we found the pieces in in the pan. A lot of fine metallic debris, silver...

"That's Impossible" Probably pure happenstance that engine ran at all. The cam timing is that sensor on the drivers side head near the front. I forget how the firing order goes but every so many seconds another piston hits TDC and 1-6-5-4-3-2 , only running on 1-5-3 probably because...

Any codes? The injectors not firing should trigger a code Sent from my iPhone using Tapatalk Pro

Sorry I have to post to reread the thread, I wanted to get the details of what it’s doing. How did you test spark? Have you tried swapping sides (cyl 5 to 4)? Sent from my iPhone using Tapatalk Pro

Well you need 100psi bare minimum to have enough compression to combust properly. These engines are spec 175-225psi. Far as I remember I don’t think these engines are interference engines. Maybe on the mistimed. But I would think it’d do something else you might notice. Sent from my...

As long as they use the original exhaust manifold it doesn’t matter if the new engine/cylinder head has egr or not. The egr port goes through exhaust manifold so the original with no egr port block it off. Sent from my iPhone using Tapatalk Pro

That $75 key sound like it’d likely be a clone on the key you do have. Not a bad option. To add a new key they need to program your Jeep to accept the new key. If they clone it all they need is your working key at their shop. You’ll need a new key added in the computer ( for a total of two...

I knew someone who taped a key near the transponder in the dash so he could use regular keys. I’d rather have the security system work as intended over convenience, but I get why you’d want to creat a work around. Sent from my iPhone using Tapatalk Pro

Yep. I’ve done the same thing. Even bought some unprogrammed Chrysler fob of the right kind frequency (miscut keys) and used those oem guts in a new key blank. There are a lot of choices but none as tough as the oem which I cannot find a equivalent of. The very cheap replacements have a screw...

Restore can help, but I’d only use it if you know the engine is on its way out. I’ve had one engine respond well to the treatment and one that had the oil pressure sender get clogged from it. But if you know there’s a problem then it’s worth the risk. IMO If you’re engine is otherwise ok then...

Water pump or freeze plugs can be a place to check for leaks Sent from my iPhone using Tapatalk Pro

We have they key with the fob built in, don’t like it. Had one of the original keys case break. Already had a cheap spare programmed in, but the Chinese keys with electronics are questionable quality while the oem electronics are better they do not sell oem quality key blanks and case so I...

I didn’t read the whole article, however what I wonder is being a 2007 does this option need to be enabled via the Star system? The proprietary software the dealer uses. I know for the Jeep fog light kit on the commander the dealer has to turn on the option for the body computer to allow the...

Nobody does this swap with GC or commanders and the engine bay was designed for these engines. On the WK and XK there are so many modules and computers to adapt to a new engine or drive train it keeps any kind of upgrade swaps from being viable. The old days of XJ and ZJ, if you could make the...
