Early AAA VR6 Engine Timing

[jim_cliff11 0]

Hello all,

I currently have the engine dropped out of my mk3 VR6 so I can give it a good overall. Milage is currently on 136k and as expected she has lived up to the notorious wearing upper tensioner rail, its literally eaten 90% of the way through. Anyway I am after some advice........

I have turned the engine over and over by hand to make sure the timing points match up. However I cant find the notch on the lower crank pulley to match it to the little line mark on the block. I have locked the cams off using 3mm plate and made sure piston 1 is at TDC so I know everything is locked off as intended. However can anyone explain to me why my pulley does not have a mark as shown in http://forums.vwvortex.com/showthread.php?1264409. The block does, just not the pulley. The only markings are the ones shown in the pictures below:

^^ Link above shows block notch, but there is nothing on the pulley.

Do the indented circles on both pulley and block mean anything? As these are the only ones I can get to line up.

Engine number : AAA031017

Any clarification would be much appreciated.

Thanks,

JIm

i had same problem pal i couldnt find any marks on the aux pully either so i ended up timing my bottom end using the notch on the flywheel and maching it to the point on the bellhousing/clutch inspection hole

Strange that you have no notch on the crank pulley, never seen one that doesn't! You can time it up using a dial guage in cylinder no. 1 if the engine was still in place but since youve yours out, line the chamfered tooth up on the crank sprocket at the rear of the engine (timing chain end) with the join in the bearing cap and block. Make sure the pointer on the intermediate shaft sprocket is lined up too. It shoud be pointing to 12.00.

My crank pulley also didnt have the timing notch . i just set visualy cylinder 1 to tdc and then double check using the intermidiate sprocket to be sure . I have to say it is a pain in the arse tbh .

Thanks for the feedback chaps.

V6Horse how did you double check using the intermediate sprocket? I think ill just use the dial gauage option on cylinder one. Should both cam locking slots be dead horizontal?

and towards the top, not the bottom
