Hello, sorry for so many questions, But I am on a 2007 Jeep Lib. I had all timing marks lined up, and the book says to rotate the engine twice and the marks should line back up. But of course they did not, both cam chains were off, everything else seem to stay lined up. Would being 1 tooth off cause this, or do I need to have all the slack at the bottom of the chain while installing the guides?

I think I answered this before here is verification if chains/timing is correct. Otherwise you'll need to rent a book on this as it's way to much for us to send to you

Hello, so this jeep came back after running fine for a week, pass. Side cylinder head was recently replaced due to #6 having a bent valve. Now I have codes for multi misfire and #6 again. Ran compression test, no compression on entire cylinder head, 2, 4, 6, had 20psi. Driverside had 150 psi. I took off timing cover. Chain was tight, with cam gear at level at 12 O'clock, crank marks lined up. Did the cam spin the pin off the gear? Why lose of compression on entire side with no chain slack at all? Thanks

Found the problem. Pass side cam jumped one tooth. Tensioner failed. FYI the coil packs have seals on them, if theyre crap and loose, you will get a miss fire code. The coils are junk.

Ok soooo. Its all back together, it will start running for about 2 min perfect, then shut down,
My guess is (if applicable) since the battery has been disconnected for so long, the security system needs to be reset possibly? Theres no abnormal noises or anything, acts like the injectors are just being shut off, fuel pressure test cranking was 59psi. Within spec. Any help Ken?

If the security light is flashing then yes, close all doors and lock the drivers door, then wait 5 mins and unlock the door, this should reset the system, please let me know what you find AL514

Are all the chain guides okay? If the chain is slapping the tensioner it will fail. Also did you hear any strange noises while the engine was running?

Best, Ken

Since it jumped it can be a stretched chain as well as other parts. It depends on who did this and how long ago. Because this is an interference engine probably valves were bent. If it was done by a shop then it should be warranted if done a short time ago.
