MG MGA - MGA oil filter

When I took my oil filter assembly apart the top part looked like that below. On Moss Motors parts list it is item 17 in the early Tecalemit picture. Apparently they don't sell this part. But mine is missing the top section of this part. Does anyone know if mine is correct or if its been modified? If it was, does anyone know where I can get the correct part? Mine was missing other parts too, like the spring. When I ordered PN 329-230 from them, it was too small in diameter to fit around the bolt. I'll contact Moss about this.

Looks like your internal filter head is broken. Pretty sure that top part is an integral part of the casting. Start watching eBay for a good used part. I don't have any of the early style parts.

These canister assemblies are interchangeable as complete assemblies. The early one-piece canister does use a different external pipe that will not swap with the others, so if you switch from the early style to a later style two-piece canister or a spin-on adapter you will need the later style pipe.

I may have a complete set of a later two-piece canister setup, including the pipe. If you're not a stickler for originality you might like a spin-on unit for convenience (but I think the Moss hanging spin-on adapters still have the jam-on problem).

Thanks Mick and Barney. I thought the part was broken. I'll keep an eye on ebay for one. I'd like to keep it original. The car won't be back together for several months, hopefully.

Barney. Have you tried the late model (18V) oil filter adapter as used on the later MGBs? I have one retro fitted to my 68GT where it easily replaced the older cannister style of filter. I think it would fit into an MGA, but do not have the engine in my A right now, so cannot say for sure.

Dave, let me know if you still need one as I think I have one somewere and the boxes of parts I have.

Dave,
I have several old oil filter assemblies in my parts piles and I will check today and get back to you. If I have one you can have it for postage. Have a good day!

John or Bill, It would be great if you can check to see if you have one, number 17 below. If you also have the small clip, number 24, and the spring, number 29, that would be great too. I'll gladly pay for shipping plus a reasonable price. Thanks in advance. Dave

Dave,
I have the complete assembly, including the pipe and mounting bolt, off a '56 MGA you can have if it is the right one for you. I converted mine to have an oil cooler and spin on oil filter (spin on from above type) many years ago.
Email me directly with an offer if you want it. I am in BC Canada.
Peter.

Peter, Let me wait until I hear back from John or Bill as I've already painted the pipe, canister and bolt head engine color and only need the internal parts to complete it. Thanks, Dave

Les, -- I've been using the MGB style inverted spin-on adapter for years. It is slightly tight quarters between the distributor and generator, but has more space with an alternator. It also obstructs access somewhat for wrenching the distributor base clamp, but not entirely. Oil cooler hose is a cinch to install with this type filter adapter.

On the plus side, filter changes are the easiest, and it doesn't spill oil if you punch a hole in the top to let air in to drain it first. It allows R&R of the starter motor and also R&R of the engine without removing the filter (for clutch or gearbox service).

For those of a suspicious nature, drain back is not a problem with engine off, because the only way oil can get out of the filter is if you let air in. It will not allow drain back any more than a suspended filter. The best you can do to stop that is to use a filter with anti-drain-back valve to slow oil from draining down from the cylinder head. Over extended engine off time oil can drain back from the head via leakage at the rear cam bearing and crankshaft bearings, but filters have nothing to do with that.
