Ian Foster Posted March 19, 2023 Report Share Posted March 19, 2023 I've settled on using a Mann W713/9, which is 100mm long. Ian Link to comment Share on other sites More sharing options...

Pete Lewis Posted March 19, 2023 Report Share Posted March 19, 2023 why there is so much faffing around trying all the alternative filters is still a mystery to me ive used club filters since 2003 on both the Vit6 and 2000 spin ons and have no trouble at all drain back is a an ongoing been doing it for 50 years some hold better some dont and depends on filter angle as most have found is never quite where you want it the original side mount and the spin on herald/spit side mounted all work well as designed on their side . what ever you do with the filter will not stop gravity emptying the gallery and crank journals so what are going to worry about next Pete 1 Link to comment Share on other sites More sharing options...
rlubikey Posted March 19, 2023 Report Share Posted March 19, 2023 Pete, years ago a group of people over on the Club Triumph forum tested several different manufacturer's oil filters and decided that the Mann filters had the best non return valve. Not all the Mann's have them, but others have not one but two non-return valves and these were considered the best. 2 hours ago, Ian Foster said: I've settled on using a Mann W713/9, which is 100mm long. Ian Good choice Ian. That is one of the double non-return types. As for my choice of very short filter, an engine-back 6-pot Spit has very little room to squeeze the oil filter below horizontal between the pressure relief valve and the chassis. The W77 juuuuust fits. Cheers, Richard Link to comment Share on other sites More sharing options...
Steve P Posted March 20, 2023 Report Share Posted March 20, 2023 I have a Mann 713 on my 1500 Herald, that always drains back anyway so i spin it over without choke for a few seconds to get the oil going. S Link to comment Share on other sites More sharing options...
johny Posted March 20, 2023 Report Share Posted March 20, 2023 yes theres very limited choice for that filter thread so difficult to find a double non return valve version and I believe some owners do a conversion to a more common type....

S Not so much a trick, but part of a security system?. Hidden switch behind the dash in the Ignition supply line, also allows to spin the engine a few times and raise oil pressure, before switching on for start.

Pete Lewis Posted March 20, 2023 Report Share Posted March 20, 2023 be it single or double anti drain it is just a rubber flap closing the return flow its not anything hi tech and some the double resists priming so it can make what ever you think you are trying to solve even worse its really not a thing you need to be paranoid about ..... but so many are I will stick to cheap and change on alternate oil changes as the service manual suggests for the mileage and use we put our cars through they are more than adequate sorry i just dont support the drain back as a problem happy motoring Pete 1 Link to comment Share on other sites More sharing options...
johny Posted March 20, 2023 Report Share Posted March 20, 2023 Probably right Pete because of course each NRV must add a little pressure drop to the oil flow and it seems our engines certainly cant afford to lose any of that😁 Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 20, 2023 Report Share Posted March 20, 2023 Johny its only my views, after years of testing everything its fair to say you cant replicate what the manufactures manage from your shed . i just like if its good enough for Triumph it works for me without any preconceived myths or must haves everyone can do what they like but if you do what was developed you dont tend to need any aspirins every day rules for every day drivers , if you like specialised thats fine lets drive Pete Pete 4 Link to comment Share on other sites More sharing options...
Steve P Posted March 20, 2023 Report Share Posted March 20, 2023 I agree Pete,modern must haves etc. I am a tinkerer as both my extensively modified cars show and having thrown more money at them than I ever could get back but, having spent a small fortune building a modified 1500 for my Herald, and grenaded it after 500 miles due to coolant getting in cylinder no. 2, and then another complete rebuild at more expense (3k) I tend to want belt and braces.
