I am a little confused about locking my camshaft and crankshaft at tdc. I am preparing my engine to remove and replace my IMSB. I have a 5 chain 2002 boxster base.

I am replacing the imsb with a LN eng. ceramic bearing. LN's instructs you to lock the crank at tdc and the exaust cams. There is only one locking plate suitable for this installation (5 chain).

My question is should I just lock one exaust cam or should I be locking both?

Thx in advance for you recomendation.
