Can't find TDC mark

Post by tmccar »

I am in the process of removing the cylinder head from my 1998 Corsa 1.0L. (It's got the engine mount which needs to be removed when changing the alternator belt.) I am trying to find the TDC mark on the case but for the life of me I can't see it. The Haynes manual is not that clear where the mark is found.
Would anyone have relevant pics that might show it more clearly?

And the mark on the crankshaft pulley - I think I have located it but it's very slight. Is this normally on the outside flange or on the inside(i.e nearer the case)?

There should be a mark on the crank that lines up with a line on the block

Crank shaft should be the same but if you can align the cranks to each other and it'll be fine, I'll try get pics
If it doesn't fit,
force it,
If it breaks,
It needed replacing anyway :thumbs:

Thanks Johnny - when you say "align the cranks", do you mean the cam lobes?

I ment cams but yeah basically there will be one gap in each of the cams that will be different to the rest if the two are aligned together it'll be spot on

Also if you get a locking kit it'll be alot easier

Looking into it abit the 1.0 doesn't seem to have marks on the cam

Apparently you need a locking kit, and find tdc on the crank then turn the crank slowly until the locking pin slots into the cam

That's for a c but it should be identical to the b

Ok - I've ordered a locking kit.
Can you make the picture bigger? I can't make out the text.
