IMS Install Issues?

[dirkdiggler]

Got the LN bearing and clip thing installed into the car tonight but cant figure out how to finish.


I cant seem to get the final part on becasue the entire assembly where the bearing is installed has shifted upwards a little. Tried to tug it down a little but No luck with that. How can I get this thing lined up straight again?


I did also remove both cam chain tensioners also.......which apparently I was not suppose too do.........dammit!

Well one article said to remove tensioners completely and the other article I read said to only back them out half-way or so......... I chose to remove them



I thought both cam tensioners where the exact same but after looking closer at them they are different. Anyone know which one goes on which side of the motor? I mixed them up and dont know which goes where now? One does have a slightly larger end on it.


What do I do now??

I guess the pic didnt attach

Pretty much the tube that the bearing sits in shifted upwards and I need it to be centered in-order to get the final piece(cap thing) on

I think I would call Charles at LN immediately...I believe I've read in the past you've likely jumped timing and now have a real project at hand.

God I hope not??

don't stress; you'll get it sorted. what year is your car? i'll assume it's an early one.

first, there are actually three tensioners. there's one on each head and one on the block. find the third one and remove it.

it sounds like your IMS is just caught on the block a bit. try tapping the flange gently with a plastic hammer & see if it pops into place.

the tensioners ARE different. look at the top of each one. each has a hole in the center. one has no rings around the hole, another has one ring around the hole, and the last has two rings around the hole.

no rings: bank 4-6
one ring: engine block
two rings: bank 1-3

get back to us w/ the year & we'll go from there on engine timing.

okay, i just saw in another thread that you have a '97.

now we need to check the timing. set your engine to TDC. on each head, there should be one side w/ two green plugs and another side w/ one green plug on the camshaft ends.

on the sides w/ two plugs, pull the lower plug out (exhaust cam). the notches in the ends of the cams should be perfectly vertical. if they're off significantly, you'll need to re-time.

i plan on posting that procedure later today w/ photos.
