Great.
My mechanic said he put the motor at top dead center so I can only assume it is. What can i expect going forward now? |
well, you can expect this to take a little longer.......
go ahead & pull the firewall cover behind the seats in the car. this will give you a view of your front pulley & we can guage where the motor is currently positioned. |

Thank you for the diagrams I got the tensioners figured out now based on the rings they have....thank you! When I install the tensioner for banks 4-6 into the left-side of the engine ...... the IMS moves slightly from side too side ......... but not downward unfortunately. Keep in mind that I have NOT loosened the tensioner on the front of the motor located under the ac compression yet. The motor is still at top dead center according to the pulley. Do you think by removing the tensioner on the front of the motor it may move downward a little? ........or is that a long shot? pics attached |
before you do anything else, lock the motor. you do that by sticking an 8mm pin / bolt thorough the hole marked OT on the pulley.
which tensioner did you poke back in? the one that goes in sideways, or the one that goes straight up from the ground? Quote:

i put the one that goes sideways back in

I actually put them both back in for the time being becasue my buddy needed his rack to fix a customers car.............we have been working on this at night
|
Looking at the pic of your IMS bearing, it looks like the flange would slide in OK. Get it started, and then use the 3 bolts to pull it in. If there is resistance, do not proceed, but it looks like you'd be ok. Once the IMS flange is in, put the tensioners back in, and roll the engine over a turn or two and check your timing. If it's in time, consider yourself lucky, if it's not, you'll have to go through the timing procedure to re-time the engine.

The IMS is outa center pushed up and too the right............ it really doesnt have any play or wiggle too it (as far as I can tell) which would allow it to go back to center where it needs to be to get the flange on. With it being off-center I dont see how it is possible for the flange to slid on ........ everything has pretty tight tolerances and it seems the only way the flange will actually go on is if the IMS is dead nuts centered.....which mine is not.
Im thinking about maybe rotating the camshaft pully a little to the right or left and see if the IMS will straiten itself out............. or is this a very bad Idea? From what I have read, it doesn't seem like removing the third tensioner located under the ac compression will have any effect on what my problem is ............ or am I wrong?? Thank you very much for all the help thus far guys!!! i appreciate it! |

If you locked the engine at TDC and removed the tensioners (you only need to remove the tensioners for Bank 1-3 and the IMS drive chain, not the Bank 4-6 tensioner (the one under the A/C compressor), I still can't see how you got the thing off center in the first place. I suppose it MIGHT gain you just a little bit of movement potential to remove the 4-6 tensioner, but you shouldn't need to do this. |
Thanks for all the help guys
i did end up getting the flange in after removing the tensioner on the front of the motor. Anyone have a link as to show me how to check the timing on the motor just to make sure I didnt jump a tooth? I did remove the green seal things on the front of the motor and the rear but not sure what the timing marks are exactly? |

Thanks for the nice write-up Kenvin ......... this should be the standard for DIY threads!
I do have one more question regarding the intake cam notch location. 1.) My pulley is set to top dead center 2.) my exhaust cam notches for bank 1 are lined up parallel to the seam between the head & the valve cover My question: My intake cam notch(one next to air oil separator thing) is pointed too the right but its not perfectly horizontal like to ones in the pics you provided. Mine is sorta at a angle pointed upwards a little. Pic attached of how mine is situated with all other things lined up. Red arrow shows the angle. Is this normal?? |
totally normal; you're fine. the one in my pic is actually pointing up a bit, too. the angle makes it look perfectly horizontal.

Mine is definitely positioned a little higher than yours is in the picture......... does it matter just as long as it is pointed in that general direction. I also put the put back in and siliconed the green cap before I checked on the timing of the other banks the motor does turn over by turning the pulley and does not bind or get stuck on anything. I think I should be ok. if the timing is off on the 4-6 banks will my motor blow up if I start it? |
you're in good shape. FYI, the green caps are supposed to go in dry.
the timing has to be off a LOT to generate interference between the pistons & valves. the concern here is really drivability; if you're off a few degrees, the car will just run crappy. |
