I see more digi problems than kjet..
Lots more of them left 
Only because they are newer. 
Took engine out of a 1985 mk2 gti today, stripped it down to just the block and head ready to clean up tomorrow morning. Brought a new clutch to fit before engine goes back in as it was past it's sell by date. Going to replace exhaust manifold studs for when I fit my new 4 branch manifold and sand blast a few other parts to make them look tidy. New radiator is also getting fitted, going to flush engine, replace oil & filter, replace spark plugs, gaskets, cam belt. All water pipes are going to be checked/replaced and fitted with new jubilee clips, generally I hope to go mad on it and put engine in next week so the job needs to be done properly!! Just need to find some new studs for the exhaust manifold at the mo so I'm going to have a look online now. Fortunately I have a full car of spare parts of which some parts I'm selling.
