Crankshaft Won't Turn Clockwise After Inadvertent Counter Clockwise Turn- It Feels Locked.

[sjmcarz]

I used the cam (rear) locking tool from IPD. The tool was in the rear cam slots correctly and the allen bolt tightened in the middle at least i thought it was. The timing belt was still on and tensioned when I tried to remove the crank pulley bolt, and the crank and cams moved together (counter clockwise) because the cam teeth didn't allign with the timing belt cover after the counter clockwise turn. Everything appeared intact with the rear cam locking tool upon inspection after all this happened, meaning it appeared to do it's job but the cam pulleys still turned.

That's actually good news that the cams and crank moved together, I thought that the crank moved and the cams didn't. The engine might be ok unless the timing belt skipped several teeth when trying to undo the bolt, or if you removed the cam bolts thus possibly allowing the cam gears to turn without the camshafts turning. So the timing belt is still currently on and tensioned and was never taken off? If so, did you remove the cam locking tool to see if the engine will turn? Are the cam gears still bolted to the cams?

Yes the timing belt is still on and tensioned and was never removed. The cam locking tool has been removed but the engine still won't turn clockwise...still seemingly in a bind. I removed all spark plugs to see if that would help anything but no dice. Yes, The cam gears are still bolted to the cams.

I appreciate all the advice so far.

Given this new information, indulge me, what are you trying to turn the engine clockwise with? The same 3/8 ratchet? My reason for asking is if you are fighting a compression stroke it would be difficult to do with such a small device.

[bwebber]

I'm trying with both the 3/8 ratchet and an actual torque wrench but I'm definitely not forcing anything with the torque wrench since I'm afraid to make things worse.

The OP removed the spark plugs.

My apologies for the misinformation but I'm using a 1/2 " ratchet not the 3/8.

Hi, I did a timing belt and cam seals on my S40 not long ago and am having trouble understanding how the cams could move with the cam lock on...and the cam lock tool still be on properly after they moved.

You say you are using an IPD cam lock? Does it look like this one: http://www.ipdusa.com/products/5127/109573-camshaft-locking-tool?

If so you cannot use that type to remove the cam gears, you need one that locks from the rear of the engine (drivers side).

Also, that clicking sound, could that have been the timing belt jumping teeth on the crankshaft gear? that is something I would check.

Another thought, you didn't loosen the cam gears any at all before doing this? I'm not familiar with the C70's, do they have 2 VVT gears? Maybe the gears could have slipped on the camshafts? You were putting CCW torque on the gears, its possible VVT gears could have come loose just from that.

Have you put the car in neutral yet???

Hello all,

Not trying to bash anyone, but having the car in park shouldn't matter. If having it on park prevented rotation, the car would never crank (or idle for that matter) with the transmission in park .

As far as the OP, I would highly doubt you bent anything using only a 3/8" ratchet. If you were hitting valves, you'd have to turn pretty hard to bend them I'd imagine. I'd suspect something in the VVT hub more than anything. '01 only has CVVT on the exhaust hub, and it is spring loaded (meaning the hub moving in the CCW direction is normal, even with the cam itself stationary). Intake hub should be fixed though. You're sure the intake hub moved as well?

Livens,

I used the rear can licking tool from ipd not the front locking tool. As far as jumping teeth on the crankshaft pulley I don't think so because I can't see the mark on the crank pulley looking from above. And no, I didn't loosen the cam gear pulleys at anytime.

Keaton85,

Unfortunately putting it in neutral didn't correct the issue.

Joe,

I was actually using a 1/2 inch ratchet w/30 mm socket. I I didn't use that much torque when I went CCW. Like I said I went two CCW turns, heard clicking sounds both times and stopped at that point. I was able to turn the crank back clockwise the same amount back to where the cam markings were TDC but the crank won't turn any further (clockwise) at that point. So the cams are now TDC but the crank marking is about 10 or 11 o'clock (I can't tell for sure because the belt is still on and blocking my view. I should go ahead and remove the belt I suppose.

You need to get some advice from a pro at this point before any more potential damage occurs. If the crank won't turn, it sounds like you've got a piston against a valve(s). Do not force it! I'm confused as to how the crank could turn if the cams were locked. Had you loosened the tensioner before attempting to break the large nut free. Or was the belt so loose that the crank gear jumped teeth? The vvt sprocket will move a few degrees either way with the cams locked but not the solidly bolted gears. And if you are replacing cam seals behind a vvt, there is a very specific sequence for tightening that type of gear, so as to get it set correctly. Good luck. Try and get someone to look at it that knows these well.

I just wanted to give everyone an update. I removed the timing belt and once I did, I was able to move the crank clockwise again. With the cams TDC, the crank was about 10-11 o'clock...I think the belt jumped a couple teeth when I originally tried to remove the crank bolt. Since I was able to return the crank to TDC (had the cams locked with the rear locking tool), where everything lined up, should i expect any timing or interference issues now? I feel like I should be in good shape if everything aligns and the crank turns freely once I reinstall the timing belt.

I appreaciate everyone assistance so far.

[sjmcarz]

As long as it turns freely after you install the timing belt, i would give it a go. Start it first without the cover and without the accessory serpentine belt on just to make sure it's ok before buttoning it up. It may not be a bad idea to run a compression check at some point but make sure it runs ok first.

[Keaton85]

It will be fine, just do what you were planning, get it back together and move on.

[livens]

Make sure you turn it over by hand, clockwise, 2 full revolutions of the cranckshaft pulley and check that the timing marks all line up still. Do not try to start the car before doing this. If something is off you can just rotate CCW to get back where you started and try again.

Good luck and let us know how you make out!
