This weekend coming up, I would like to measure the timing chain stretch on
my 6.9 ('79)
I've been told you simply pull out all the plugs, rotate the engine till its
at tdc on the crank pulley then you pull off the right hand cam cover and
check how many degrees the cam shaft is retarded... sounds easy enough.
what am I going to see, a line on the camshaft sprocket and a line near it
that it should line up with ??
the left hand cam cover gasket is leaking, so I'm replacing both and I
wanted to do this while they are off.
And to change the chain, you just have to undo the tensioner on the left
side of the engine, link the new one to the old one and feed it though,
almost sounds too easy, is there a catch ?
