There's different specs for it. A couple have a higher spec than the others. Good thing it didn't strip the threads.

That was for lsj not sure about lnf.

I need the specs for the ones right by the cam gear. Seems 10 ft pounds but not sure

lnf is 22 ft lbs first pass and second pass is 100 degrees for the vvt motors.... the cam cap bolts are 89 inch lbs, tensioners 55 ft lbs, cam position sensors are 89 in lbs

note: the camshaft sprocket bolts should not be re used.

89 inch pounds??? wow i over did it lol

talking about journal cover bolt specs here. and do i just blue lock tight so they dont work loose? like my valve cover bolts did

Omiotek

ive never had any of that stuff back off with torque specs. the cam journals are crucial to be even... i really think you need to get a tech to help you out man.

tomj77

well i checked one and it was about 130 inch pounds, so i put a little blue lock tight on it and set it there, we shall see i guess, ill take it apart when i get stock bolts and see how it is.

Omiotek

yeah they are always over torqued. most people wrench them down

tomj77

well she runs. lol tick is still there seeing as i chickened out of changing tentioner, but at home it was gone, it comes and goes, maybe someone is living in there. lol ill just get a stock bolt and replace the hardware store temp one im using and ill leave it alone. the tick ill take into another dealer to look at and screw it

You really need to reset the timing chain tensioner whenever removing the timing chain for any reason.

If you don't it could cause premature timing chain wear.

no one removed the chain

ordered my new bolt from create engine, learned 89 inch pounds, well i learned by screwing up, yay. lol

Omiotek

iTrader: (2)

Yeah and there is a torque procedure aswell

FasterIsBetter

Yeah, and if you don't have an in-lb torque wrench you can convert it to ft-lbs by dividing by 12. I ended up having to do that cause the in-lb torque wrench I ordered from summit doesn't read out in in-lbs but rather ft-lbs....89 in-lbs would be approx. 7.4 ft-lbs

i got one of those ones with a screen that attach to a normal socket. but i misunderstood how much to torque em and went made one way to tight, thats why it broke

not on those, they are just 89 inch pounds. thats all the repair manual says

there are the 10mm bolts that hold on the cam caps, they are all 89 inch pounds from what i read on the manual

Omiotek

its one of those things you just gotta know... its always good to go from the center and work your way out. its it a 100% neccisity? no but its good to do it. just like its also good to get them started and after then tighten up give them like a half turn so theres tension and after you have done that to them all you go back a torque them all to spec. thats just what i do

tomj77

iTrader: (2)

i know but its only one bolt on the end lol no need for all that. just replace the bolt. but still good to know for someone who changing them i guess

Omiotek

yeah i figured u had them all undone. no big deal
