hello to every one.

Ive just put my cylinder head back on after taking it off to replace the head gasket and got the head skimmed at the same time (138.50). i wanted to find out how much clearence ive got between my valves and pistons but when it came to cranking it over manully the enigine wouldnt move it was solid. what could be the cause of this and what other ways are there to check the clearence between the valves and pistons.

 

does it turn over at all if it turns then locks up check the timeings set right

 

no it doenst turn over by hand at all. The engine is all timed up correctly. it turns over easy when the head is off.

 

timing 180 out >?

 

if it's timed up correctly then it can only be 1 or 2 things the valves are hitting the pistons or the cams caps are too tight/seized!

Cossie???

 

Turns over by hand with the head off because of no compression. Check your timing again.

 

All well and good checking timing but as he says he's trying to check valve/piston clearance. Have you had too much taken off the head?

Also have you tried to turn it over without the plugs in?

 

take belt off then turn each shaft indevidually, see which ones stiff. probly a cam. are cam caps on right and in the right order?
cossie???

 

call me i can probably help sort this problem

 

Hardly mixed up cam caps by any chance.

 

yes it is a cossie engine, 2wd sapphire.
all the timing is correct and all the cam caps are in the correct place and tightened correctly. the head thickness is 138.50 but i got told thats ok.

 

can any send me a few pictures of what the cam setting should look like. i know ive set it right but just to be on the safe side.

another thing does the camshaft sprockets go on the cam one way.

 

On the std pulleys the 2 pointers should point directly at each other.

 

the V in the bottum pully is not TDC its the lug that comes after it that is TDC only saying as iv nown lads to set the timing up of the V

 

All so pull all the plugs out as this will help you turn the motor over . But Dont hit the key till the motor turns over by hand at least 2 or 3 times

 

Here is an old thread ive found bud,

everything is lined up properly to the tdc marks. il give it another go again later.

 

it works know. i think it was me being weak trying to turn it over . but thank you to all for the help.
