cam position at TDC..?
Sorry but I have more questions...
My car has a BBI underdrive pulley that does not have a timing mark...
and I am trying to lock the crank at TDC.
Can I lock the crank at TDC based on the position of the cams ..?
Somehow I cannot download the picture better go to bed and try again in the morning :-(

The purpose of locking the crank at TDC is to prevent the crank assembly from moving while releasing the cam drives. You should not be attempting this without the pin locking the crank at TDC as locking the cams will not stop the crank from rotating, even if it means temporarily putting the stock pulley back on the engine.

Hello Jeff,
I am sorry when I posted the message it was way past my bead time... LOL
Yes, I WILL be locking the crank at TDC (at the flywheel side of the engine), the question is can I determine TDC by the position of the cams since my underdrive pulley does not have a mark on it.
Sorry for the crummy picture

If both cam locking tools will not slide in completely it is not at tdc. hopefully you still have your old crankshaft pulley, it can't be more than 15 mins of work to slip that back on. Otherwise how are you locking the crank at TDC?

HS,
1) The cam locking tool I was able to borrow does not have the tabs that slide into the cam notches, it has two bolts that press against the cams to keep them from rotating (by friction)
2) I was planning to lock the crank at the rear (flywheel side) using a steel bar between the crank bolts and the bellhousing
3) Unfortunately, when I installed the underdrive pulley, I used plenty of locktite red (yes, shame on me...) and I don't have a big enough breaker bar that will be required to loose the crank bolt, however, I do have the OEM pulley
By any chance do you have the locking tool that locks the cams by inserting the wedges into the cam slots? I live in Yorba Linda and I am very close to Tustin...

You can line the cams up using the notches, but be aware they are not symmetrical (centered):

Jeff,
Thank you much for the picture, I will ensure that the cams are aligned the same way as the picture, 2-6 bank center picture (Cayman driver side) and the 1-3 bank right picture (passenger side)
NOTE: The Smaller 1/2 moons are facing towards the outside of the engine, right?
Once I align the cams I will lock the crank, then the cams and I can move on and remove the chain tensioners and lastly the IMS cover..
Getting there... Thank you for the support!
