Low Power 16v

[Tomonator1985]

Hi.

Had the timing done around 500 miles ago. seems like its losing power the same way again.

How can this happen??

might be worth checking the woodruff key on the pulley ok?

talk me through that............

Start tipex markers and check for movements dizzy, idle screws the usuall suspects
Haven't heard about the woodruff key going in a very long time guess check it to rule it out
Bet that caused a few head scratching moments

cheers. it's basically nothing i can check on my self!

when the garage sorted it out last time it was out by a long way. engine was rebuilt using a old corrado donor.....should beexactly the same engine though right??

New crank, engine out if its damaged can't weld it either. Heat damages the shaft plus if you repair it only becomes loose again. Most peeps struggle to remove the crank pulley bolt which if you get that far replace the crank bolt with a stretchy type.
I would start with basics first as most people end up dropping new block in 

Check if the crank bolt is loose it could just be that?
Was a cam belt done recently?

I've got a doweled abf crank pulley, using a dot punch stem. New bolt and pulley from vw, loads of bearing lock and loctite, over 350lbft of torque (if I recall correctly), and been fine since. It gets hammered every day as well. The old 9a I repaired using a screwdriver shaft as a dowel lasted a while, but not forever, though that was old bolt, old pulley, and an impact gun to do it up, rather than a fooking great extension bar. But yeah back to the matter, check timing marks 1st, then go from there. Do a search, the basic 16v key ingredients/ checklists have been covered many a time..

damaged keyway reapir  involves cranck out and milling out the keyway,     then broaching out the pully to new keyway size.   cut new key  drizzel in bond lock and do the bolt up FT.

1.8 crancks are generaly redaly avalible so it's not like you'd ever bother tho

what we talking price wise if i go to a garage?
