Hi,
After changing head gasket on a 1.6 dohc nuberia on a 99 plate ..i cant get my crankshaft pully off to see the timing marks but i did set the pistons to tdc and the timing marks on the camshafts to the correct place but after doing this i get no compression on cyl 2.. but on every other cyl ..so my question is should the pistions be set to tdc or a few degress off?..

Cheers Gary

always TDC when you set timing. as for the cams you would have to check the repair manual to see where the marks should line up

Anybody help on this one...i have it so both marks on the cams are pointing towards each other in the middle is this right?

Cheers

That's correct. Look at the "how-to" section http://www.daewootech.com/forum/viewtopic.php?t=2746 .
I'm not that sure that the crankshaft gear timing mark is correctly aligned only by setting piston at TDC. Anybody know? Try again to remove crankshaft pulley to set mark for sure.

You are going to have to take that pulley off. Get an impact wrench. Or, get a breaker bar and wedge it somewhere sturdy then bump the starter.

first off how did you manage to remove the timing belt with the crank pully on??

try my way for removing the bolt:

1- get the correct socket size
2- get 90 deg. bet wrench that is long enough to collide with the suspension's control arm
3- install the socket and wrench and make the wrenche's arm as close as possible to the control arm.
4- remove coil pack socket
5- clear the area arround the fron right wheel.
6- crank the engine for a split second - a loud knock will be heared during the process... this is OK, make sure the car is in neutral position.
7- remove bolt then pully.

basicly we are using the starter motors power to remove the bolt off... it is kinda dangerous but works like magic, i hold no resposbilty for damages and/or injuries consequent to using this method.

P.S: when the crank notch is alighned; the #1 cyl. is at TDC indeed, look elswere leaking on #2 cyl. like a problem in the gasket's installation or a stuck valve... i don't think this is related to crank marking at all.

Just thought i better say that worked like a dream..came off no problems Also i think either the head was warped or a valve was bent either way i just got another head from the scrappy and it worked fine I did have a few other probs but im gussing your saw my other posts..lol

As for taking the cam belt off i didnt i just left it on ..but now i got the pully off i did change the cam belt

Cheers
