Hi all
After a long time of gathering bits, and getting the courage to attack this job, on Sunday morning I finally started the teardown, I was tired of coolant leaking from the welsh plugs at the rear of the head and from the water pump.
I was a little apprehensive as this motor has not been touched internally since 1985. I was worried about the condition of the block surface and whether the liners would slip and I removed the head.
However, I was pleasantly surprised at everything. It all came apart very easily. Lots of cleaning of parts was needed.
I even ground smooth all the casting marks from the exhaust manifold, washed it in the dishwasher then coated it and put in the oven for a few hours.
I have fitted a 505 series 1 square port head with matching inlet manifold. Fitting the existing Solex carby to this new manifold took some fabrication (modifying the auto kickdown bracket and making 4 studs to attached carby to manifold). But all installed now with all hoses connected.
Since the block surface came up so clean, I did not use any sealants on the head gasket. I torqued the head down in three passes ending up at 80 ft/pds
Only issue I have is that the carbon contact to engage the fan sits about 8mm shy of contacting the fan hub. This is really strange. The hub is on correctly. So maybe the carbon is worn down or the spring inside the housing has lost its will to go on. I'll order a new one.
Here are some pictures:
All that is left now is to adjust the tappets, attached the rocker cover, install spark plugs, leads and distributor cap, fill with coolant and sort out the fan carbon contact. All before Bastille day car show on Sunday!!
