MG MGB Technical - Inverted oil filter type in Australia

G'day. Read as much of the archive that I could trying to find a suitable filter to fit the inverted adapter, but they all seem to refer to UK and USA types.

What type of filter available in OZ should I use?

Thanks
Tony

Tony. The German made Mann W917 is one of the best filters for this application. It is used on various Volvo products and has been tried by a number of us with excellent results over the years. I have to special order mine in bulk. Not a problem because my local BAP store has a manager who used to own MGs, we have been dealing with each other for years, and he will keep ordering a year's supply at a time as long as his company has the Mann filter available.

This filter has been good because of the excellent "anti-drain back" characteristics. K&N also has a line of premium filters, with the HP2004, I believe, being the one recommended for the late model MGB.

You should be able to cross reference these two filters and see what other brands provide a similar filter which is available in your area. But, after a number of years of testing, on four cars, I will make an effort to keep using the Mann filters.

Maybe there is a difference in inverting the oil filter since you guys in Australia are upside down or maybe we are upside down depending on your view of the world.

Tony,I'm not sure which type of filter you're using, but if it's the type that hangs down, a Zyco Z9 ( Ford Falcon) will fit.If it's the type that sit's up then you need one which has baffles in it to stop the oil draning out. One of the local dealers , Nepean or MG Centre should be able to help.

Tony,

My contribution to your thread "Spin on oil filter - warning" of April last.

"Not sure which adaptor you are currently considering. The one I have is from an Austin of like vintage to the Bs and it takes the Ryco Z23 filter, to my knowledge the only available filter here for the adaptor type, which has a 1/2" BSP screw fitting for the filter. Price here is around $23-26.

Important with the Ryco is that it comes with both the anti-drain valve (LOL) and the pressure bypass valve built in. The adaptor itself does not have a bypass valve...

It is possible to have a thread unit made for the changed version I have - that would be 1/2" BSP into the adaptor housing and, say, a 3/4" UNF thread for the filter itself. That would make for a wider range of filter choices, both Ryco and other brands, but whichever you chose would still need the bypass valve, with or without the anti-drain back feature."

Ryco have a website with filter details - and a search facility. That would be a place to start and it would give you a Ryco reference to check against other brand numbers available here. Those commonly cross-reference a Ryco number.

I went through this filter thing a couple of years ago after wrecking a good engine with oil starvation and ended up searching through all the filter books and found the filter off an early 323 BMW had the right sized 'o'ring seal. It is a smaller filter , doesn't drain back and has a built in bypass valve that blew off at the lowest pressure difference I could find. I think it was only about 3lb from memory. The only catch was it was a different thread (18mm from memory) but it's no biggy just get another threaded piece made up. Also, don't get caught out using too thick of an oil. I used to run 50 weight race oil but went back to 40 and this filter and all is well Hope this helps Gary

Tony I have tried a few of the popular makes and with the upright position of the filter the drain back valve has always been the weakness (leaking over time) I have now settled on the Baldwin BT216. You get instant oil pressure even after lying idle a couple of days. I am using them on three cars and time will tell but so far so good.

Thanks Gents. I'll be taking my list of 10 filters to my supplier to see what he can get. Obviously I will be insisting on a drain back valve. My knowledge of oil filters is at best non-existent so am I right in assuming the by-pass valve is there to allow oil flow if you don't change the filter for a few years.

"am I right in assuming the by-pass valve is there to allow oil flow if you don't change the filter for a few years"

Well, yes, but also - and more importantly- in the event your filter medium blocks or collapses and ceases to allow oil flow through its membrane. In that event oil passes straight through the filter cannister.
