cam locking problems
Hello-
Im trying to prep for ims change and lock everything down. I have a 3 chain motor, and have the pin in the pulley at TDC. The cam locking tool on bank 1-3(serpentine belt side passenger)will not fit. The tool only goes one way, i know. I turned the crank another 360 degrees and still no fit with the pin locked in. There is a small notch on the pulley that lines with a mark on the case, and i was making sure that was aligned as well. It seems to just not fit in the top cam slot. Yes, they both look vertical. It seems that i can get the locking tool in if the tdc pulley mark is some 10 degrees atdc, but then the punch wont fit i to the pulley lock. Im stumped. Yes, the cam tool is part of the ln pro kit and is the long one. 2004 boxster s special edition |
If my logic is sound, the tool should never fit if a cam was off by a tooth or more. The fact that i can get it to fit, but the tdc mark is a little clockwise (1/8 inch), and of course the locking pin wont sink into pulley

Will try, but won't be able to lock driveshaft pulley with the pin if at 180. I have pics here.

You are in the exact same boat that I was in last weekend...I fought with getting that cam lock tool in for about an hour (2004 Base). I had to just keep at it...rotating 360 degrees, then rotating again, etc. Each time slowly rotating until finally I got the cam tool in, with the pin in as well. It was very tight, just keep at it.

All I have done so far is removed the exhaust, 6 speed transmission, clutch and flywheel. I gave up last night as I needed to crash after some 30 minutes at it. Reaching up to that side is best accessed from under the car (bank 1 -3) , so its a back and forth from backseat (with wrench on the pulley bolt). I was convinced last night that something was wrong, but you gave me hope. Question, I have not emptied the engine oil yet, and the car has been sitting for 2 weeks as I worked on it slowly. Does that matter ? |
Not sure, but I did drain my oil before I started my project. Removed rear bumper, exhaust, transmission, clutch, flywheel. Now I have locked the cams and this weekend will pull the IMS (hopefully). Still have water pump/thermostat and short shifter sitting on the bench waiting their turn.

I take it you just just kept turning the pulley and pin-locking it tdc BEFORE you tried to install the cam lock (in-car side 1-3 bank) or what order worked for you eventually ? |
Yes basically just kept turning the pulley, with trying to fit the cam lock and the pin at the same time. It really was a matter of micro-inches for everything to fall into place. It did take several tries though.

I should have been clear - rotate the pulley until you get the cams to rotate 180 degrees.

I have them lined correctly, just need to wiggle the crank and get the cam lock tool in. If i cant get the pin in the crank pulley hole, what about putting the flywheel back on and locking that ? Just a backup plan |

That was not fun doing alone. I had to rotate crank in the backseat and then get under car and try to fit the cam lock over and over. There was almost no room to fit the lock from the backseat, so under car was easier. A small tap with a dead blow and it slid in. I then lined up tdc mark on pulley by 2 degrees and the pin slid in. Thank you all. I hope getting the transmission back in will be easier |

Glad to hear it. You are in the same spot as me now. Time to take some deep breaths and pull the chain tensioners.....

I know the 2nd lock is for the 5 chain motor but I figure it can't hurt anything to put it on one of the two. Thoughts? |

Thanks again for your help. I just realized I referred to the "bamks" incorrectly in earlier posts. Cams have 2 banks, 2 cams each. I am planning on only removing tensioner bank 1 and the IMS tensioner. |
I tried using the other cam lock (the single) on bank 2 but I couldn't get it to fit. I think on the LN instructions they say its not necessary, and if you did want to lock the second bank, you would need to make up a lock yourself.

I will try tonight and report. I figure its worth a shot. The more we can lock the better. IMS will be saturday |
