So after I replaced the timing belt/ water pump, ecs stage 1 with lightened flywheel snd new throw out bearing on the 20V the engine I installed it into the golf. Pretty straight forward. Same mounts as the 1.6 and majority of plugs matched. The only concern was the miss matching plugs that plug into corresponding plugs under the wiper motors. Ended up leaving a black plug which never actually affected the car. I pressume its for climate control and sunroof controls.

I did have a problem actually starting the engine. Car would click but not pop and bang. Had the gearbox off numerous of times to check if flywheel was fouling on bellhousing as some of the casting are a few mm smaller in diameter and need to be grinded. Turns out the throw out bearing and clutch fork was back to front. Doh!!

After a while of running it it had a missfire issue so new plugs went it but did not fix the issue. Then on the day before new years this rattle came from the engine and pulled it right off the road. Thought maybe the miss fire issue was due to a defected ignition amplifier and maybe have done further damaged. Sump came off and found a piece of plastic was in the oil pick but no metal shavings. Pulled of end caps snd the bearings were fine so its off to Volksfactory this week for them to diagnose the problem.
