LOST JEEPS :: View topic - First post question on cylinder head bolt torque.

Thanks for the reply I just can't figure out where I'm missing the 30nm part. This is the cipied text right out of the 2006 kj manual...

If cylinder liner(s) have not been removed, the same thickness head gasket that was removed can be
used.
1. Clean and inspect gasket mating surfaces.
2. Position correct head gasket on engine block.
3. Place cylinder head on engine block.
CAUTION: New cylinder head bolts must be used. Do Not lubricate new cylinder head bolts. They already
are coated with an anti scuff treatment.
4. Tighten cylinder head bolts following procedure below.
Cylinder Head Bolt Torquing Procedure
1. Tighten all cylinder head bolts starting from the center bolts, following the cylinder head scheme and the following
sequence: 3-2-1-10-9-8-7-6-5-4-11-12-13-14-15-16-17-18.
2. Without loosening any bolts, starting from the center bolts, tighten each bolt an additional 75° in the following
sequence: 10-9-8-7-6-5-4-3-2-1.
3. Tighten the lateral cylinder head bolts an additional 50° in the following sequence: 11-12-13-14-15-16-17-18.
4. Finally tighten all bolts an additional 75° in the following sequence: 10-9-8-7-6-5-4-3-2-1-11-12-13-14-15-16-17-
18..

Post subject:	First post question on cylinder head bolt torque.
Well first time poster here... I just recently bought a used 2006 liberty crd. Got it cheap has 150k miles original timing belt and two broken off glow plugs # 3 and #4. Previous owner had check engine light for glow plugs took it to a shop they broke off 3 & 4, then wanted to replace cylinder head and gave him a huge quote for.the job.... He just wanted to get rid of it. I picked it up removed cylinder head bought a kit for removing broken glow plugs off ebay... Got them out. All were original 7v ceramic glowplugs. Anyways I bought a cd with the factory kj service manual. But the head bolt tightening instructions never list the initial tightening torque it just says tighten in the said sequence then do the 2 angle steps afterward.... Can any one clarify this for me. Am I totally overlooking something in the service manual? Thanks in advance. also great crd info on this forum lot of great writeups!

viewtopic.php?p=749162 30 NM then follow the angle instructions.............I highly recommend ARP studs though. The factory bolts are known for poor long term performance.

X2 on the ARP's! Very few people on this site reinstall factory bolts. They tend to cause a leak eventually. ARP's are about $300. You also probably want to replace the rockers. Are they nice and tight, or are the needle bearings sloppy? I've never seen one that had 150k and good rockers... GDE engine tune keeps the new rockers in good condition

There are lots of things not included or just simply deleted................very common with the jeep service manuals. Just look under the Noob guide and see the link for fsm downloads from SirSams site. They are free and you can check out the 05 manual. The 06 had a lot of the missing info from the 05 year (they are almost the same) but it still isn't perfect.
