You are correct Donnie thumbs up
You didn't ask about the mods you needed to make
to make up for a changing your timing chain case.

Jim and I are out of order for chatting about them sad smiley

When I did this a couple of years ago I think I cut the canister off, sealed the hole or pipe stub) and soldered on another pipe in a benign convenient place in the the timing chain cover for the crankcase ventilation.

Jim from British Auto Parts clued me in to the fact the 948 timing cover has a felt seal as opposed to the later covers having the updated seal. He also said some fellows would bash the canister in and some guys would slice it the way Jim English suggested. I took the easy route and carefully reshaped the canister with a body hammer and block of wood. It did not take much and now the fan clears. If anyone is interested I used the Midget water pump pulley and the Morris fan and it all works.

Thanks for the replies

Sorry to take so long to reply about the Morris Minor question. My computer has been down.

A few years ago I purchased a recently fully restored 1950 low light tourer complete with sv engine of a whole 27 bhp. It was delightful but I found it woefully underpowered for modern traffic.
I thus purchased an ex US Sprite motor of 1275 cc and installed it in the Morris. It was in many cases necessary, and in others desirable, to upgrade to Minor 1000 specs along the way. I also fitted 9” Morris Major brakes to the front.

One picture shows the original engine as purchased. It has the cylindrical canister attached to the timing chain cover. It was of course removed to make the engine fit. Another picture shows that the hole left in the timing chain case was soldered up to make it air/oil tight. I think it is the disturbance over the hub of the camshaft
A third picture shows the ½” copper tube soldered into the side of the cover to connect for crankcase ventilation. It is just visible under the water pump. A PCV valve was inserted into the line as depicted in another photo to deal with crankcase ventilation.

For some reason this set up did not work. The crankcase seemed to be pressurized and I tried all kinds of things to fix it. These included fitting catch tanks, removing the PCV valve, plugging the timing case spigot and tapping the crankcase as well as numerous other ploys.
The problem was improved but never finally cured when I sold the car. It may be that it had a broken piston ring. I had read of other owners on the forum who had crankcase pressure problems but no definitive solution.

At the moment I am rebuilding a Datsun 1200 engine to install in another as yet unpurchased Morris Minor.
