Question regarding cam timing

The Monty · 05-08-2010, 09:59 AM

Question for the tech heads, if my head has 12thou off it, how far would I need to advance the cam till its at 0 degrees?

only a guess but - nothing, wont the tensioner make up for it?

I have no idea, thats why I was asking. I was thinking a 160 000km old engine will have a slightly looser timing chain, and added to the 12 thou off, my cam set at 0 would be a couple of degrees retarded.

Anyone have an idea?

To be sure, you'd have to set the cam by its specified lift @ TDC rather than relying on degree marks on the vernier.

Back in the day we used to have EL cabs with timing chains so loose they'd slap against the timing cover at idle

Nah it's just been so, so long since EL's were cabs.
And for me also it's a world away since i was turning a spanner on EL's
