bottom pulley sounds 180 out try turning the cams slightly and then turning the crank , also are the cam pulleys on the right cutout?

[sri-bex]

the cam pullys are on the right cut out but havent tried turning it 180 then trying again thanks for your help i will ty o mora and let you know

[sri-bex]

do i turn the crank 180 clock wise or 180 anti clock wise from my tdc mark thanks again

i might be being thick but i dont think it will matter because you will end up in the same position whichever way you do it!

180 degrees out means the crank is the wrong way i.e on the return stroke rather than the upstroke or vice versa hence will be shoving pistons wrong way to compare with valve opening/closing = no compression normally. Thats how I understand it anyway, basically in layman's terms it wont start lol ;)

as above hence havin a timing mark on the bottom pulley!:cool:

ok ty 4 you info give it ago 2 mora nite will let u no

[FaT-AsTra16v]

i confused???
u say u turn the crank and after half a turn the cams do a full revolution?

normally 2 full turns to get the cams to do one rotation so half a turn would turn the cam pulleys a 1/4?

[sri-bex]

the cam pullys turn fine when it is lined up with the tdc mArk and the crank is lined with the tdc mark i put the timeing belt on i turn it bye hand 3 quarters of the way and it stops

[FaT-AsTra16v]

sounds seized? maybe a valve stuck open?
have the cams been removed at all?

[stumpy]

ive had this before while timing a xe first turn the bottom pulley so the timing mark is at 3 oclock postion then put your top cam timing into postion after that adjust the bottom pulley to its timing mark this will correct yor fault and allow you to put the cambelt on and time it perfectly

whats is happing is your bottom pully is incorrect at the mo ie piston to high in the bore so when u try and move the cam the one of the valves is hitting the piston this is why it wont move

[sri-bex]

ok thank i try that before i took it a part i timed it up on the cam pullys and on the crank pulley was not on the tdc mark so i maked my own mark was this ok

[Andy_gsi]

all the timing marks should line up best bet take the belt off line up all the timing marks pop the belt back on then turn it by hand, make sure it turns over ok a few times

hope you havent tried started it?? bent valves if you have

[sri-bex]

no m8 havent try to start it when i try to line it up on the crank pulley it want turn to it point it just goes to the point i made

[stumpy]

better to use the standard timing marks if you do as i said you should find there will be no probs

cheers lee

[sri-bex]

ok ty lee how can i get it to the tdc mark if it want go to it shell i line it up on the crank with the timing belt on then line the pulleys up

[stumpy]

remove the belt and time it up then put the belt bk on!
should be fine
lee

[sri-bex]

ok ty m8 ill have to try it 2morrow tanks again

[sri-bex]

hiya all ive sort the timing out now but there isnt any compression we towed it and it started and run for 5 mins now it still want turn ova with the key any help please

[rhydgte]

How did it run when started? Mint? Or misfiring?

If all is well when running, dead battery? Starter Motor? Starter Solenoid?

[sri-bex]

misfring m8 loads
