MG MGB Technical - something missing in my oil filter housing?

I'm in the middle of changing the oil and filter of my '68 B and just taken the oil filter housing off. I've a feeling that there may be a plate missing which seals the bottom of the filter element so 'input' oil is separated from 'output' oil. Am I right in thinking that I need a rather large washer shaped plate attached to the stub inthe base? Here is what I have. The element just popped straight on here and I can see no way the elementy would be effective. The hole in the bottom of the old (an new) element was larger than the stub. The bits that can away were the housing, fixing bolt, plate on the top of the element and the element itself. Nothing on the bottom.

i think you should take a look inside the old oil filter as i think you may have sheared it off. I have the same housing on my 68 gt and you normally have a tube with thread on it sticking up at least 2 inches. is this the canister type oil filter (modern type) your using or the older one where you replace the element? mine is the modern one.

The modern canister type has the threaded tube. Yours looks more like an early type mounted above the filter housing. Try Haynes p.25 There appears to be spring, washer, sealing ring, plate, clip to hold the element in place.

No doubt someone who has this type will be along soon-mine is the canister type!

Haynes does show a big disc fitting over the boss in the middle, extending almost out to the groove for the sealing ring. If I had more time I could post a photo, sorry.

Yes you are missing a critical plate.

The filter is not the modern screw on type thus the reason for calling it an 'element'. I discovered that I'm also a sealing ring and washer missing between the top plate and the spring. Obviously the PO must have lost a few bits. I'm hoping there were no 'bits' in the oil as the filter was obviously not filtering as it was being bypassed. I'll have to make a plate up as no doubt it's not available as a spare. I believe the seal is though.

Steve,

I would think it likely that someone has changed from the canister type to the spin on type, and still has the old parts around that you could buy. Alternatively, you could change to the spin on type.

The pic looks like the adaptor that is sandwiched between the canister housing and the block casting and takes the oil off to the cooler. Thats sealed by rings top and bottom and the fixing bolt goes through it without touching it . And yes there is a big dished pressure plate that goes under the filter element and a spring that forces it up, and can be pushed down to allow oil to continue flowing if the filter gets blocked.

Haynes photo attached. The manuals only identify the filter head, not this part separately, which does seem to be NLA. The dished plate under the filter element (or above for an inverted) is a *different* plate, the spring at the closed end of the container pushes that plate onto the filter element to seal that open end, and presses the element onto the plate that should be in the filter head that Steve is missing. The bypass valve for when the filter element gets blocked is a separate part of the filter head, I think, seen at the top in Steve's photo.

So it looks like I only need to make up a plate like that show in the Haynes photo. I'll see if I have some ally plate. Should be a small piece somewhere. Looking at the MGOC website the exploded view of the components show a felt washer between the spring and the dished plate. Some rubber sheet and a hole punch should do the job. I was wondering what to do with the time I had allocated to watch the Grand Prix. It was on earlier than I had anticipated so I missed it!

Processional, with some incidents. Last time Hamilton went out when his front suspension broke when hitting someone's rear wheel, which wasn't all that surprising. This time he went out when his rear suspension broke after coming into contact with Webber's front wheel! Webber undamaged. No wonder Hamilton threw his steering wheel away. He didn't refit it (that I saw, a marshall was wandering about with it) after he got out, probably get a penalty for that as well.
