1200 grade wet & dry on barrel sealing surfaces. Before (L) & After (R)

These are not budging so I’m going to leave them alone.

I did get the fire rings off eventually.

Cleaned and Ready

Pulled the pistons. I use a flanged M8 nut for the gudgeon pins.

These cheapo verniers are no use here, there is no way these pistons are 0,5mm under spec. @ 93.4mm Barrels all measure 94mm. Pistons all weigh 452g

That’s it for today.

Oh and I’m done with cleaning, i.e. lost interest! This will do.

Oh cleared all the gunk out of here, but can’t remember what this hole is for, off hand.

Some numbers, 93.991mm

Rich @ Crazyquiff’s (Mk1 Golf specialist) welded a engine case for me, way back when, so I know he has a welder with sufficient power to repair the crack.
So much heat gets dissipated through the case, so it takes some doing.

Talking of Mk1’s; I enjoyed my Mk1 Campaign, we made the front cover of Practical Classics and attended a photo shoot. Pub quiz knowledge; Campaigns had green tinted windows, which I always thought was a nice extra.

Anyone got a url for Hymolar AF?

Head No.2 has issues. Need a machine shop for these broken studs ideally.



...and the barrels need honing. I don’t have that tool.




Cleaned up ok though,fire rings and valves are out.

Pushrod tubes can be used again. Bench mounted wire wheel used.
