My MK4 cut out on me, it turns over but won't fire.
RAC looked at it today and think it may be the timing, if it is and the engine comes out for it what else would be worth getting done whilst the engine is out?

Hmm. That depends upon a whole load of things. If everything is in otherwise excellent condition, then little more to do than the chains.However, if the chains need doing due to high mileage wear, then you might want to consider a new clutch whilst the engine is out, Rhe engine internals themselves should be in good shape, provided service intervals have been maintained. It looks as if these engines are capable of very high mileage before requiring major overhaul, the cam chains being the exception. All the ancillaries are worth a good look at , and a new alternator belt a good precaution. Great opportunity to give the engine bay a good clean .
Just my thoughts.Others on here are far more experienced .
Thanks for the response, to clarify, it's a one previous owner car with full service history, I've had it for the last seven years and kept up with the servicing via the same independent VAG approved garage, used it as a daily driver, currently at 150k miles.
Clutch sounds like a good idea.
what else is worth getting done?
prob the local bank with a bill that will be coming your way!!
glad to see youre repairing it tho :-)
Clutch and flywheel for a MK5 is a must whilst the engine is out... I'm assuming this is the same for the MK4!
At that sort of mileage, despite the excellent servicing , once the engine is out, the rule is that expect to replace most items and be grateful is some parts are serviceable . You do not want to take the engine out again for perhaps another 150k
Turbo while it’s out
Turbo over a supercharger? I realise it's more power but would it change the dynamic of the car too much?
When I had my chains done, it had a bunch of other things done
Timing chains, guides. Tensioners etc., the 2 intermidiate sprockets as they wear out too.
Water pump , thermostat as why the hell not
Check the 'crack pipe' coolant pipe for damage
Various gaskets
Changed the spark plugs
Check the vvt units work properly. Check the tiny oil screens inside them are as they should be
.new clutch. New clutch slave cylinder. New flywheel
And I fitted upgraded cams at the same time .
Check the downpipes and manifolds are in order too, if need be upgrade
Wow thanks for the whole list, that's really useful.
I'd actually previously looked at manifolds after doing my exhaust but didn't go through with it at the time due to work commitments.
Do you loose anything with a cams upgrade?

Good point, thanks.

Replace the Propshaft coupling/doughnut. Meyle HD ones are about 60 quid on ebay.
May the boost be with you
.:Rotrex powered sleeper...well sort of....
You can only plan so far.....After that, well you have to take a few leaps of faith.......
Thanks for all the response, there is some great information here.
In the end it wasn't the timing, I had a high-flow fuel pump fitted that had burst the fuel line.
