east-west 1275 block
east-west 1275 block
Just thinking aloud today, given their similarity from the factory, would a 1275 mini block be able to be fitted with all north-south components for an A30/35?
I did a bit of a search & saw someone who had done it the other way around (Midget block on a Mini)
any thoughts?

Re: east-west 1275 block
Not easy.
You need a Midget or Marina crank and rods and the rear main bearing cap from the same engines.
This will need to be machined and line bored to align with the other two.
I would also recommend fitting the M.E.D. rear oil seal.
You will also need front and back plates from a Midget engine. If you have all those parts then you have almost a complete Midget engine anyway.
I once put a Marina crank and rods in a spare Midget block just because I had all the parts lying around, which is nowhere near the same thing.

Much easier to go the other way, from in-line to transverse...

I do have a complete (I think) Marina engine....

You can fit a remote filter ...

Very easy modification which accommodates an oil/air cooler in the same circuit...gazza82 wrote:You can fit a remote filter ...

Re: east-west 1275 block
But not necessary as the position of the Marina filter still allows fitting of the engine. There can be a problem with the filter hitting the steering box but a smaller filter from (I think) a 2CV solves that problem.
You still need the appropriate front and rear backplates though

Re: east-west 1275 block
Small oil filters are not a good idea. Always use the biggest one which will fit in the space available

Re: east-west 1275 block
And when there is only limited space we compromise (Or as I,m sure you would advise, fit a remote filter)

Gets over the problems of smaller oil filter having greater flow restriction (and pressure drop) and the need to replace it more frequently...Dave Clark wrote:...(Or as I,m sure you would advise, fit a remote filter)
Downside of remote filter are additional fittings which can leak and possibility of the hoses chaffing to point of failure. But worked fine on Cooper S as standard fitment. Also provides means of coupling a Marina block to an oil cooler which I've always found essential even on the road: A-series cook their oil

I have seen Moss promoting a Dynolite oil of 20W- 60 viscosity. Would this be of benefit to my engine ?

Re: east-west 1275 block
Modern philosophy is to use the lowest viscosity oil capable of withstanding engine loads, minimising parasitic loss to the benefit of fuel economy. Older design engines have large clearances and oil passages so 20w-60 should be ok, but I doubt there would be any benefit over 20w-50.Countryboy wrote:I have seen Moss promoting a Dynolite oil of 20W- 60 viscosity.

Never use such high viscosity oil in a modern engine because it can starve the bearings.
Still need to keep engine oil temperature under control (max 120C) or nasty things happen. Modine oil/water coolers/heaters have some advantages over oil/air coolers especially on road cars...

Re: east-west 1275 block
I have just changed the oil in TMT and used fully synthetic 10/60.
Re: east-west 1275 block
Dave - Why do you use 10w-60 viscosity
Re: east-west 1275 block
thanks for the ideas guys, will see what we end up with once the resto starts in earnest.
Just realized I've started this thread in the wrong section <sorry!> can the mods please move it to the right one? thanks.
