SPIN-ON OIL FILTER

[janus@iafrica.com]

Some listers' TCs, like mine, have a modified oil filter that accepts a modern spin-on. A few days ago I inspected my TC's oil flow - pump to filter line enters the top/centre of the filter housing and exits from the side to the block. I compared this to the spin-on filter I was using (GUD model Z93) and noted that it had a rubber washer/ring just below the outside holes which indicated that the intended flow is in reverse order, i.e. in through the side and out through the top/centre. I phoned the local GUD agency, and technical staff not only confirmed my suspicions but also advised that the internal paper element was structured to operate in that manner. Further, there apparently is no filter (except cartridge-type) in the GUD/FRAM range that would operate in the required manner. So the solution seems that I shall have to reverse the oil lines so they enter the housing from the side and exit from the top/centre - and bedamned that it is not according to factory standards! Any advice/comment would be appreciated. Luckily I have adapted the oil lines to the flexible variety!

Hi Joe, I make a spin-on oil filter adapter for the TC. Its an aluminum round machined piece which replicates the top half of the original oil cannister. Uses original oil lines, banjo bolts and block attachment. The adapter is CROSS DRIULLED so the oil enters the top of the adapter, flows sideways through the adapter and enters the spin-on filter from the outside. The oil then passes through the filter and exits the center of the filter into the adapter where it flows sideways to exit the adapter on the side. Hence we have proper oil flow through the spin-on filter ( outside to inside ) and still use the original configuration of oil lines. The back flow flap valve in many filters is not required on the TC but does no harm as long as the oil flow is in the right direction. Original TC oil flter cannisters had a metal screen on the outside of the filter mesh and this allowed oil flow from inside to outside. Modern spin-on filters are designed for flow from outside to inside and have a re-inforcing screen on the inside. Different design entirely. Some oil filter adapters have been made which flow oil directly from the top inlet straight down into the center of the oil filter. If you have this type of adapter, you should reverse the oil lines to get the flow in the correct direction through the filter. Personally, I don't like this solution as you never know when some other owner/restorer/garage will decide the configuration is incorrect and "correct" it and you end up with the oil flow being blocked by the filter flap valve. My adapter is available from stock and resolves the problem. You need to be sure of the oil flow direction through the adapter before you start changing oil flow by re-routing oil lines. You may be causing a problem. Regards, Bob Grunau Some listers' TCs, like mine, have a modified oil filter that accepts a modern spin-on.

Joe: The first thing to check is where you got the adaptor. If you are using the phil marino adaptor you dont have to change a thing. Just hook it up and run it. The changes are internal on the adaptor. DONT reverse the lines. Skip Kelsey...................................... At 12:43 PM 5/8/02 +0000, janus@iafrica.com wrote:
