Just need to have the crank pulley locked on TDC and the exhaust cam lock installed on Bank 1.

Which brings me to my question: I am at the point right now trying to understand the correct method of setting the engine to TDC compression stroke on Bank 1.

All seems pretty straight forward with aligning the crack pulley notch with the TDC indicator on the block, and using the cam locking tool to lock the Bank 1 exhaust cam vertical with the seam in the block ( Mine is the 5 chain system).

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

New member here. I recently inherited / purchased a 2000 Boxster S. It is a low mileage car and I have decided to take the proactive route and do the IMS bearing myself. Having built a 180MPM kit airplane (
RV-8
) and flew it for several years I know how important it is to read and re-read instructions over and over again before starting any work, which is what I have been doing regarding the IMSB retrofit.
Which brings me to my question: I am at the point right now trying to understand the correct method of setting the engine to TDC compression stroke on Bank 1. All seems pretty straight forward with aligning the crack pulley notch with the TDC indicator on the block, and using the cam locking tool to lock the Bank 1 exhaust cam vertical with the seam in the block ( Mine is the 5 chain system). What isn't clears is once those two tasks have been done. should the intake cam notch on bank 1 located on the flywheel side be facing outward or inward to be correctly set at TDC on the compression stroke?
I have come across two postings: one states that the intake notch should be facing inward and the other states it should be facing outward. I am not sure which one is correct. Any help would be greatly appreciated.
BTW GREAT forum!!!.

With the crank locked TDC, with the locking pin, you also use this lock (pictured) on the cam. This lock is located on the right side behind the passenger seat (US vehicles) front of the motor. This picture was taken with the motor still in the vehicle.
So, Once the cam lock is installed like in your picture on the exhaust cam bank 1, then it appears that it doesn't matter which direction the notch on intake cam on bank 1 is facing either in or out, is that correct?
Thank you for your reply.
Thanks for the link and I just read it and there was no mention of the orientation of the intake cam notch, so it apparently doesn't matter as long as the Crank is aligned and pin in TDC and the exhaust cam lock ( on the 5 chain system) is installed on Bank 1( Per your image), then I should be good to go.
Thanks again for the info.
Jager, thanks for the link and I read the article. I didn't see any reference regarding the intake cam notch orientation, so i guess it doesn't matter. Just need to have the crank pulley locked on TDC and the exhaust cam lock installed on Bank 1.
Thanks again
This is a source reference. Confirm exact model applicability in the original material.
