changing tappets
Discussion
Hi guys
Going to be changing my tappets in my Mk2 Golf GTI. I understand that I need to mark up all the pulleys and the belt so that they allign when I put the belt back on however I am confused about the cam shaft. How do I know what way round it should go in is it attached to the cam pulley? As I can just mark the pully up with the block and make sure I got it in line.

Well in a nutshell, the pulley is bolted to the cam and there are already timing marks on there. make sure you time everything up properly before you take anything off and replace with new belts and tensioners. Depending on if yours is SOHC or DOHC, mark the cams for inlet/exhaust, so you dont get them confused.

It's obvious which is intake / exhaust on the Mk2 Golf - the timing belt only drives the exhaust cam (one with the big pulley). Then they both have a small cog at the other end with a chain to drive the intake cam off the exhaust cam. Get a new chain from VW too as it's likely yours will have stretched over time. Blue print parts are apparently best avoided for the chain - genuine VW is the way to go.
The cams can really only go in one way, so no worries there.
Even if you lose your timing marks it's not the end of the world as it is quite easy to time it up right. Some of the VW forums have great guides on this. ALWAYS try turning the engine over by hand with a ratchet on the crank damper bolt before trying the starter (also worth doing before you've put all the covers etc on too). Triple check the timing marks all line up correctly, and you should be fine.

I take it I can get away with just losening the tensionor pulley and just take the belt off the cam pulley?yes its fine to just remove from the cam pully .
i tend to use a cable tie to just hold it upo save it dropping .
i would check with vw regarding a cambelt kit because a lot of the vw tenshioner bolts are actualy stretch bolts so need replacing otherwise failure will acure.
also handy to have a dial gauge or atleast feeler gauge
possibly the only vw engine i have never done work on but i would imagine there all the same regarding tenshioners etc .
check you have the tool to tighten the tenshioner up , undoing it is the easy bit .
as mentioned before once its all back together turn the engine twice by hand then check all your timing marks are still spot on to check belt has not got jammed or slipped as will result in the valves getting smashed on pistons no doubt , dont let that scare you quite simple job .
