Hi All, I need to ask some mechanical advise from those in the know please.
I'm just about to put the head back on my block and after sussing the job out before just need to check a few points.
1/ I need to get No1 piston into TDC position, however the block is currently in an engine stand so I dont have the benefit of being able to check the flywheel TDC markings and lock accordingly.
I found a paint mark on the front crankshaft pulley and figured that this would need to be positioned at either the 12 o'clock or 6 o'clock position. At 12 o'clock No1 poston was at bottom dead centre, when the mark was at 6 o'clock the No1 piston was at TDC.
Front crankshaft pulley mark shown below (I added this one so that I could see where it was with the front belt pulley attached. The original mark is on the front face of the front crankshaft pulley).

With the pulley in this position the No1 piston is at TDC as shown below, not sure how clear this image is but the flywheel is to the left timing gear to the right.

Does my thinking make sense?
2/ Camshaft pully timing marks.
The camshaft pulleys have two marks (both pulleys are the same) one is an "indent" in the pulley and next to it is a white mark to the right of the indent.
On the timing cover there is also an indent and next to it a white mark. I feel like I'm answering my own question here but I just want to check the its the "indents" on the pulley that need to be lined up with the indents on the timing cover?
Can someone please confirm or otherwise please?
Have all F7R engines got these two timing marks (as it could be confusing) or is it something particular to my engine?
3/ I also need to tighten up the camshaft pulley bolts tomorrow and I dont have any special tool to do this. I'm going to try using the old timing belt crimped onto a flat bar in ordevto hold the pulley still whilst I put the required 50nm into the bolt.
Does this sound like a suitable method?
First time I have done anything outside of general servicing on an engine, so currently outside my comfort zone.
Any feedback or advise greatefully received 👍
