Oil Filter

[brian bax]

My TC is fitted with a modern oil filter conversion from Abingdon Spares and I have been using Austin Mini oil filters. I have now discovered that the VW Golf/Polo (Rabbit in USA?) range use a similar filter that also appears to incorporate a non-return valve which would seem to be a good idea. Can these filters be used? Is there a general preference for any particular filter type or make? Any advice would be appreciated. Brian Bax TC3550

Brian, By "non-return valve" I'm guessing you mean an anti-drainback valve. You need one to prevent oil from draining out of the filter when the engine isn't running if the filter is not mounted vertically below the adapter. I'm not familiar with the Abingdon Spares adapter, but if it mounts in the same position as the original TB/TC/early TD filter then the spin-on cannister is probably horizontal below the adapter. If so, you don't need an anti-drainback valve. However using a cannister with an anti-drainback valve won't hurt anything. What's the make and part number of the Austin filter you've been using? I have a fairly complete set of Fram catalogs, so can cross-reference the Austin filter to get the thread and gasket sizes. Once I have that I can tell you what Fram filters are appropriate - with and without anti-drainback valve. -- Chip Old 1948 M.G.

Aaaarrrrgggghhhh! Engage brain before typing, Chip. That should be "vertical", not "horizontal". -- Chip Old 1948 M.G. TC TC6710 XPAG7430 NEMGTR #2271 Cub Hill, Maryland 1962 Triumph TR4 CT3154LO CT3479E fold@bcpl.net

Hi Brian, I supply Abingdon Spares the oil filter adapter they sell. The adapter has a 3/4"- 16 TPI, National Fine, parallel thread for connection of the spin-on filter. Therefore a number of different spin-on filters can be used, as long as the oil is intended to enter the outside of the filter and exit the center and the filter connection is 3/4"-16 tpi. The adapter is cross drilled to allow the oil to enter the top center of the adapter and exit the outside to the spin-on. The oil then passes through the spin-on filter and exits in the center. The adapter is again cross drilled to allow the oil to exit the adapter out the side. The non-return valve found on some oil filters is not needed on the TC as the filter unit hangs down and will always remain full. Many filters also contain a bypass valve and this also is not needed on the TC as the oil pump bypass is still in place in the block. However, the check valve and bypass valve should do no harm if present. I use a Fram PH3600 filter unit, a bit longer than stock but easy to find. An MGB PH966 filter also works and gives the approximate original overall length when used with the adapter. Oil filter brand selection is a matter of choice. I really can't say which brand is better than others. I did have a filter test comparison but lost the information when I had computer troubles.

Aaaarrrrgggghhhh! Engage brain before typing, Chip. That should be "vertical", not "horizontal". Right Chip, the adapter hangs down and the filter is vertical with the open end up. Therefore no need for the flap valve. The adapter replicates the top half of the original filter canister and uses original mounting, oil lines and banjo bolts. The spin-on just screws on from below. However, I also make a spin-on oil filter adapter for the late TD/TF oil pump and this has the spin-on filter horizontal. In this application it may be a good idea for an anti-drain back flap valve. However, originally the late TD/TF did not have any such valve in the system. Email me off list if interested in a spin-on filter adapter for the TB/TC/early TD or late TD/TF.

Brian, I've already seen the good responses from Chip and Bob. I use one of Bob's adapters on our touring engine and are very happy with it. We use a Fram PH16 filter which does have an anti-drain back valve and is common to our '73 MGB, our '93 6-cylinder Jeep and our old 140 and 240 series Volvos all of which have the filter in a vertical position with screw port uppermost. I was about to write to the list with a related question. We use the later integral pump/filter on the racing engine with a sandwich plate to go off to the oil cooler and then an adapter for the spin-off canister. Last season was the first for a new block and I wasn't happy with the oil pressure behaviour. I opened the filter canister only to find the anti drain back flap had kinked back under the spring almost implying that oil had tried to flow from inside to outside. Could I have a problem because the filter bypass valve in the filter housing (in the block on a proper XPAG) is too weak? Could my oil cooler provide so much resistance that the valve opens and lets oil into the gallery and hence backwards into the filter at start up? I thought of trying a new valve, but would it be a problem to block it off and with what? The spring is in a special housing and fits into the filter housing with a very fine thread. The spring feels very weak to me and has no "adjustment" like the pressure relief valve in the pump. Of course I don't have a tool to measure spring tension. Is the PH16 filter type the right one to use for a horizontal application? Has anyone seen technical data on filters on the web? The Fram site only has "marketing" data. Cheers, Peter
