Timing

[milestones54]

Ok hopefully someone can give me a quick answer
When lining up the timing in my corsa (could be the same for other models)
I have a timing mark on the top of the cam cover, a notch on the cam gear and a block of no teeth on the crank, is this all right?
Thanks

if u mean what i think u mean on the crank, it's not right. the timing mark is on the timing pulley, i dont think there is 1 of the balancer, but that flattened bit should be directly up from memory, the timing pulley should have a mark that meets at the bottom to a mark on the oil pump where it meets the sump.

Ok so i cant see marks on either atm
Maybe a stupid question but i hear the 8v have low enough compression that they wont damage if theyre started with timing off. With the marks in the position they are now is it safe to give it a try?

Anyone?

no the sohc are still an interfereance engine!!!

take plugs out, turn over by hand (rathchet ect...) but DO NOT force it if it gets tight.

i'll check out the sohc we have at the factory n get back to u within the hr . (as long as i dont forget, hahaha)

Thanks heaps for that mate, really just wanted to get it on the road today. What am i looking for when i turn it over manually?

Hmmm, interesting...on most of these engines timing alignment marks are on the belt and cam sprocket gears...

Whatever you do, make sure it's right or you'll destroy the engine !

Ok there is a timing mark on the top right of the balancer (crank pulley) and a notch on the pulley to match it too. If in doubt, pull the sparkie out of cyl 1 and use a screwdriver to feel when it's at the top, this will give u a very close place to look for the marks lineing up. If at that stage the top doesn't line up, turn it a full 360deg to line it up IF u still have the original belt on, if uve taken it off. Pull the pistons down half way, line the top then the bottom. If at ne stage it's tight don't force it, as it could b a valve hitting a piston. Best to find some1 close by that knows but, it is easy to bend a valve.

Doesnt the balancer spin? How can there be a top right? and which other pulley?
Sorry im so eager to get it on the road, its just been a b*tch
