If thick oil helps, go for it.
Other than that, try another seal sealer, or change the seal if or when the clutch goes.
20w50 in Canada?
Would it start all winter?
Without a block heater?
No block heater.
The lowest temp it experienced was about -10c (whatever that is in american ;-) )
Honestly, at that time, i never gave it a second thought. It always started, i only remember that in sub zero temps, the stick shift transmission was a bit stiff until it warmed up.
You might ask my reasoning for using such heavy oil?
Well, I'm from the UK. There, the standard oil (the most available oil) was 20w-50
Cars there would typically last (in the late 60's and 70's) 100k miles before showing serious wear problems. These would be highly stressed, sub 2 litre engines.
When i came to West Coast North America, I saw 5&6 litre lightly stressed V8's lasting the same mileage running on 'thin' 10w-30 (the typical oil of that time)
That did not seem right with me.
So I ran with 20w50 just like in the old country.
