is there a pilot or locate hole in the crank or cam and can it be done without removing the crank pulley?

Dave 88 2.2 bosch.I went by the book there appears to a keyway on the bottom crank gear it says to line that up with a bolt above it.this bolt is off to the left of center a bit.the top one is clearly marked.I dont know what size spark plug socket this thing takes but it did not feel right.it only feels like it is only going on about a 1/16 of an inch.since it is a non interference motor i lined up the gears and figured the worst case scenario i would only be out 180 degrees.i turned the key and it started up.i put it back together and took it for a test drive i dont know if its just me but it doesnt feel quite right.i am thinking it may be one tooth off.does anyone know if they will run if they are one tooth off?and also if the spark plugs are an oddball size.? i want to bring it to t.d.c.and check the marks.

timing belt 88 bosch.got the plug out brought up to T.D.C the keyway on the crank sprocket was at 12 oclock.the manual is poor for directions it says line up with the bolt above it.the bolt above it is slightly to the left it ran poorly there took it out on the highway had trouble going over 50mph.i would suggest anyone doing this job to put it at 12 oclock on both sprockets T.D.C.took it back out its running great now.i sure dont like doing things twice though.thx Scott.

Well that is great news! I guess it means that this proves these engines are non interference type! The other few that were saying they needed a new head probably after the belt broke probably had the garage do the initial belt replacement repair wrong!

Enjoy your ride.... and try to find a cover for your timing belt...... maybe Larry
