i think it just needs a new cambelt (AND A WATER PUMP)
i think it just needs a new cambelt (AND A WATER PUMP)
loads of people believe it though.....i think its cos the autograssers(etc) allow for skimming of the cam carrier in their regs.... if you skimmed enough of it, it would push the hyd tappets down a lot, and it might feasibly allow for more revs, but i can't see it happening much......so i think its more for getting a clean surface for resealing.Originally Posted by Andy
It is a good un isnt it
Both the belt and pump are new, but I think that the belt has been in and out so many times it looks old.
What arrow is that?HTML Code:mowgli this engine is so old, i don't think it has the bottom marker arrow like the later ones.
Steve I have had the bottom sprocket off but there is no painted marks at all. How do I set it all up now?
Cheers

just put your bottom pulley back together & retime it to the pointer & notch. re time the top pulley, and when you come to put the belt back on, maybe try the notch one tooth to the right of where it is in the photo. then run it up.
Steve on removing the alternator/bottom sproket, I could not find any paint marks where someone has set the timing in the past, so have you any idea's how I am going to set it now with no reference to go by?yes your right with regards to spark timing
what needs to be done/checked is the timing between the crank and the cam.
i just took some pics but my phone cable is at home so i will post up later
unless someone can post some up earlier

notice the pointer on the pulley above this needs to line up with the notch/mark/cutout whatevers on your engine see the little cutout just below the pointer?
the cam pulley below lines up with the notch on the back cover, its a painted mark on yours so line up with that assuming the back cover has not moved as you said earlier
this is the physical engine timing, now fit the belt
one this is done turn the engine over a few time by hand to check that the marks end up in the same place.
now replace the altinator pulley and start the engine, check spark timing with your strobe light and adjust with the dizzy
hope this helps mate
As equally importent is how do I put the sprocket back on, because on my alternator pully there is a notch taken out and what I want to know is does this notch go over the raised bit just above the red circle in your first picture?
I have asked a mate who also has a nova, and he has always set what I call setting the timing and has never heard of the setting it underneath the alternator sprocket.
Thanks for your help guys, I will be forever in your debt if you get me out of this one
By the way do you use the timing light on this new sorce?
Cheers

I have just looked at the crankshaft pully under the alternator sproket on my nova and that dos'nt have any timing marks on it either.
Surely there must be a way of setting it up for the first time, or at least the first time after the factory set it?
Cheers
Mike
like i bluddy well said before..... use the notch & pointer off your alt pulley...then time it up at the top as before. then turn it over with the plugs out..... and then recheck the cam timing.....
as i also said before... the arrow on the crank pulley is a red herring on this age of car...
