im at a bit of a loss on this one :( can you post a pic of crank pulley? im away in 10 mins going camping and wont be back til sunday i could have a re-think then :)

steve

shame he's not local :) or i would have been round there by now and sorted it for him :)

lollollol oh yes forgot to say pic of this 'girl next door' ;)

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...

no no

take the bottom altinator belt pulley off (the one in pic 1), you will then see a pointer on the bottom crank cog this should be at 6 o'clock more or less but there will be a mark the notch...

what a good idea :)

^ +1 :)

give her your nova and set fire to this one ;)

i agree with mowgli 10mm is about a tooth out cant understand how you cant get it????

as i said before, where are you?

steve

:D did you get engine running?

hey stop fookin around in the 18+ section and get that engine done! ;)

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

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

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...

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...

bro in laws eh? such fun NOT ;)

you know what and its such a school boy error (cant think why i missed it :))

ITS NOT IN GEAR IS IT? lol

from what i can make out he's been trying to just turn the engine over by hand but it seems 'jammed'. lifters either empty of pumped up would have no effect on the engine turning, gasket on upside...

i agree about crank/cam not moving much, 1 assumed the O.P has the skill to get the timing ok or at least within 1 tooth.

dont know mate, i will ask around if it comes to that :)

to be honest, i dont suspect the lifters 'jaming' the engine they are just a pivot point really and should not stop the cam from turning

ok

first take the cam belt off and then turn the crank 45 degrees, this will put all the pistons halfway in the bores and away from the valves

next, remove the spark plugs then try and turn...

so, let me get this right, once the head is back together and the cam belt off, you try and turn the cam using a 17mm socket on the pulley end and its jammed solid, right?
