Head Gasket

what do you mean by slight? 1mm 2mm? slightly thicker would open the valves slightly more. however if they are more slightly, say 5mm for instance then you could be reaching the max that the valve strings would crush too and that would jam things up.

where are you? i have some old ones knocking about i think.

for what its worth a quick check would be

head off
remove all the rockers
put 2 of the old gm ones on say no.1 piston (inlet and outlet)
refit the head and just nip it down no need to torque it
turn the cam via the pulley bolt

this should turn ok

now do the same but fit the 'new' rockers

if it jams then theres your answer

Hi Steve that is very nice of you. I will try and sort it out with your tips and if they do not work I will willingly buy them off you

no worrys mate nothing drastic just beer money how much difference between the rockers then?

[gunner1x1]

Ok I had to strip the head back down again, and although I found no obvious cause, when I put it back together again it now turns ok with the risers and rockers working as they should.
But that is not the end of the matter because frustratingly now when I turn it over by hand if the top two notches are level with each other the bottom notch and pointer are about 12mm out and visa versa. What is the best way to sort this out?

Secondly I cannot fit the fuel pump without moving the above out of wack. Help

Cheers

glad you got the jamming sorted yay

forget the fuel pump for now

take belt off

turn bottom pulley so marks line up (TDC)

turn top pulley to marks

fit belt

turn engine by hand if you turn bottom pulley twice run the top should line up, i allways turn it over 3 or 4 times to confirm everything lines up each time

that should be the timing done now bear in mind that the top pulley could and its not uncommon to be 1/2 a notch out, dont worry too much if it is

now fit the fuel pump

Nice one Steve, I'll pop out now and will let you know how I get on

I really do not know what owners like me would do if the help you and other members freely give was not available. I obviously cannot give much advice to new members, so I think the least I can do is join the forum and hope that my pennies can be of some help.
