ooops!!! need urgent help!


so i was trying vigorously to remove the crank bolt on my 1.8 when all of a sudden something gave way, but it wasnt the bolt loosening it was the intake side camshaft alignment pin breaking, in doing so, the crank rotated, the exhaust side camshaft rotated but the intake side did not and now my whole motor is all out of alignment...how do i get the crank back to TDC and my cams aligned with it?
thanks again

quot;Once the belt has been removed, do not rotate either the crankshaft pulley or the camshaft pulleys. If you do, you will not be able to figure out the proper rotational alignment. quot;
and
quot;CAUTION: Do not rotate the belt counterclockwise. Someone recently did and managed to shear the exhaust cam pulley. You'll require some help installing the belt. Someone will have to hold the camshaft pulleys steady while you thread the belt on. This will take a couple of tries to get it right. quot;

see thats my problem , that is basically what happened and i need to get them back in alignment

ooOOOouch. Hmmmm well, the fix is past me scott. I didn't see further info on how t'rectify it. Someone will surely pipe in.
Good luck!

It's not impossible to get them back. If you position the cams so that the front-most lobes are at 3 and 9 o'clock (pointing away from each other), and put the crank at top dead center. That's a good approximation. From there, just get your marks lined up.
EDIT - I'm assuming you've fixed the broken locating pin?  The above won't work if the pulley is not properly aligned to the cam.  The locating pins would be straight up with the lobes at 3 and 9.

Excuse me?  What do you mean you will not be able to figure out...?

quot;Do not rotate the belt counterclockwise. Someone recently did and managed to shear the exhaust cam pulley.quot;

Shearing the camshaft dowel pins as nothing to do with direction of rotation.  The crankshaft may be rotated either direction.  Shearing dowel pins is from trying to hold the camshaft on its flats while putting a wrench on the crankshaft bolt.

quot;You'll require some help installing the belt. Someone will have to hold the camshaft pulleys steady while you thread the belt on. This will take a couple of tries to get it right. quot;

I need help and it will take a couple of tries?  No.  I'll do it myself and it will be correct on the first attempt.
For the OP:  You make sure you have two good dowel pins in the camshafts, position the pins both at 12:00 o'clock, install the camshaft pulleys with index marks pointing at embossments in center (quot;Equot; on the intake gear and quot;Iquot; on exhaust gear), position TDC notch on crankshaft cog to pointer on front of engine, install belt.  Follow tensioning procedure in Shop Manual.

Don't ask me Lance, I just cut and pasted from the garage lt;shruggt; Perhaps it could be updated with the info you two have provided here.

It would be the same if belt broke. The crank has turned, the cams are in whatever position. As Lance said, put crank on TDC, align the cams, install belt. Good to go.

We need the video from the King

thanks lance...i've got it all lined up and it makes perfect sense now im good to go...thanks to all others who offered advice

Some days I just have the instinct to change my tagline to quot;Dont brake till you see Lancequot;
