Rebuilding a 1.8k VVC - Story
Discussion
Hi,
i wanted to show some pictures and my progress here as im currently rebuilding a Rover 1.8k VVC from skratch.
It all started as i was able to get a cheap 145ps 1.8k with a little hole in it
Fortunately a friend of mine had a spare block he gave me, so i took the crankshaft and the head from the "hole" engine and discarded the rest.
As our regulations require me to have a EU3 emissions i need to upgrade the engine to the 160ps EU3 version. So the plan is to use new 160 Trophy pistons, steel rods, keep the VVC units, new exhaust camshaft (270), rework the inlets, new valve guides, REC valves (standard size), new liners, new followers, offset dovels, ZandF ECU, R500 manifold collector.

Cam ladder bearings
I cleared them, then put 1200 sandpaper on a 17 nut and carefully smoothered
I was afraid to remove too much material, so the clearing was measured
All inlet bearings ~ 0.038mm, Exhaust ~0.076mm . Rover manual: 0.025 - 0.060 inlet, 0.060 - 0.07 exhaust (service limit 0.1mm). So that should be fine

This has already been done at my local dealer. He has balanced crank, flywheel (some material has been removed before) and the front pulley.
He balanced the parts separately and then together.
He told me that the crank didnt require any balancing. Flywheel 2g, front pulley was the worst with 4g

Recieved a new VVC Head from Dave.
Valve seats has been cut to match the REC valves, head has been peened and skimmed. Currently im copiying the porting to all the chambers
Unfortunately there was an issue with the postage, so the old head has been destroyed (cracked) and the new one has marks on the freshly skimmed surface
