Hi,

I am changing the seals and washer at the weekend. I watched this really good and comprehensive video and note that he cranks the engine a little but doesn't say why other than to see the rockers rise and fall.... Can someone explain why he does this please?

Injector Seals and Washers

Thanks!

Found this, just in case anyone searches and is looking for the same:

Workshop - Injector Removal / Seal and Washer Replacement.

Rotate the engine until No1 Cylinder is at TDC (top dead centre). No1 is the pulley end of the engine. There is a couple of ways to know when No 1 is at TDC, you can either watch the rocker shaft lobes and continue to rotate until No 1 stops "lifting" or if you look at the back of the camshaft pulley (where the timing chain is) you will see a slot or key way cut out of the back.......picture arrowed below....
