richhl Posted January 17, 2021 Report Share Posted January 17, 2021 Just had an (too) exciting Sunday afternoon - on starting up my 2L Mk3 Spit (GT6 Mk2 conv) I had the oil filter get blown off (spin on adapter type).. Newly replaced oil everywhere, fortunately had tray under the car that caught most of it. Unfortunately I didn't do the usual and assure pressure turning over first as I usually do, engine ran for probably 2 mins before I stopped it. My bad, I thought pressure gauge issue and I wasn't watching the oild light as I have the speedo out... Didn't get to pump out all the oil, about half, and no load running so now not sure of possible bearings damage.... On inspection I had a wrong filter (or badly manufactured).. although had used this type previously, this is a Mann W 71328, I have now successfully fitted a WIX WL7074. The inner diameter of the thread on the WIX filter is at least 1mm smaller (tighter overlap) than the MANN filter which explains it. When I refitted the MANN filter and over tightened it I was able to get the threads to jump. Anyway, with the new filter have had the engine up to temp with no apparent side effects or noises so far, oil pressure good as before (60 - 80 psi). Any thoughts on whether I should drop the sump and have a look??? Your thoughts and inputs welcome.. from now on I will check the filter internal dia before fitting.. Cheers, Richard.

Pete Lewis Posted January 17, 2021 Report Share Posted January 17, 2021 no ,, rest easy on any ideas of sumps off its just run a while with less than best lubrication , so sleep easy this may be wrong thoughts ?? but here is the down fall of playing around with non specified filters and mythical obsessions of oil drain back why people worry about the filter when the rest of the engine drains off amuses me ( sorry getting bored with lockdown Ha ) Pete Link to comment Share on other sites More sharing options...
Clive Posted January 17, 2021 Report Share Posted January 17, 2021 Not the filters fault, it has the wrong size thread https://catalog.mann-filter.com/EU/eng/catalog/MANN-FILTER Katalog Europa/Oil Filter/W 713~28 says it is 13/16 thread, bigger than the correct 3/4UNF. The wix is indeed a 3/4 thread filter. Almost any ford, and many VW etc filters will work. Link to comment Share on other sites More sharing options...

Peter Truman Posted January 17, 2021 Report Share Posted January 17, 2021 Well that would be enough excitement for one day. Around 20 yrs ago heading back to the office I was following an unknown to me roundtail Spitfire thro the beach suburb of St Kilda here in Melbourne when he stopped very suddenly, I pulled in behind to see if I could help, the driver explained his oil pressure just dropped, on opening the bonnet it was obvious the oil filter was off lodged near the suspension turrent oil everywhere and half the screw in adapter was still in the filter. Having a Spit also I asked was he using a modified adapter/filter he responded yes a local Triumph guru?? ( not popular with us Trumpeteers) had provided it and he was on his way home, obviously the adapter wasn't up to it and sheared at the filter to block joint, it was too thin, overtightened or something, funnily enough I'd picked up 3 very rare but original Coopers Spitfire oil filters with adapters just a few days previous from a getting rid of old stock sale, and they were still in the boot. We removed the old adapter remnants and fitted a new original filter got some oil from a local garage and fired her up, IT WAS TERRIBLE a real set of hammers. The driver arranged a low loader to get home, I advised he should take the supplier on for full restitution as the adapter wasn't fit for purpose the two threads ran up to each other no shank length or hex between the different threads, I never heard how he got on, but advised our club members to be aware and only get the adapters from a good resource, not a back street charlie, specifically this back street charlie! I recently brought 4 modified adapters from a NZ machine shop he was advertising in the NZ "Trade Me", delivered they cost a measly $10 each, there of good quality with a short hex shank between threads, delivery was a little slow as he had to make them and Covid Mail issues. I only needed one for a Spit 1500 engine I was building up for the daughters car, but good to have spares in case one gets thrown away with the filter, and if need be help others.

This might have been done before - but, if not, why not have an oil filter cross reference 'look up' table on the Forum pages somewhere ?

Gav With the filters it would be difficult. You can get a super neat short filter (I recently posted it on here) that would suit these engines, and handily small filters fill quicker too, so drainback is less of an issue (and the filter has a one-way valve,) But most people simply buy from their preferred supplier. Wheras those with a bit of nouse buy a quality, branded filter, usually at a much better price! The troublesome filter is the 4 cylinder version with the original stud, "classic gold" are about the only supplier, which is not of any quality as far as I am aware. Change the stud to a 3/4 adapter and you have a choice of hundreds of filters. And I did import 30 of those adaptors, I may have made a fiver profit absolute tops on the whole lot. But too much grief to do again. Sorry, wasn't meant to be a rant. Link to comment Share on other sites More sharing options...
Nick Jones Posted January 18, 2021 Report Share Posted January 18, 2021 Mann 714/2 3/4" thread. Check Compact. Check internal NRV flap. Check (two in fact) internal relief valve. check (1.5 bar pop-off) https://catalog.mann-filter.com/EU/eng/catalog/MANN-FILTER Katalog Europa/Oil Filter/W 714~2 Work for me.

poppyman Posted January 18, 2021 Report Share Posted January 18, 2021 Heard that before Nick, but a lot harder to get and more expensive than the Mann 712/1 very similar filter but only one NRV flap from memory. Tony. Link to comment Share on other sites More sharing options...
Nick Jones Posted January 18, 2021 Report Share Posted January 18, 2021 I usually buy them from ECP when they have one of their bigger discounts on. Listed for various Alfas and Fiats. Don't go through them all that often as I change the filter every other oil change. 714/3 seems to be the same except having a single flap.

Pete Lewis Posted January 18, 2021 Report Share Posted January 18, 2021 Nicks quite right from many of the triumph service schedules is filter change every other oil change again all down to personal preference filters have far more capacity then most of us will use Pete Link to comment Share on other sites More sharing options...

I am sometimes tempted to do the same with the oil as it comes out clean, but can't bring myself to chance it. Tony. Link to comment Share on other sites More sharing options...

I was always a great believer in regular engine oil changes although mostly on my moderns - the Triumphs get it once a year. To me, oil was cheaper to replace than an engine.

Nick Jones Posted January 19, 2021 Report Share Posted January 19, 2021 Yep. Temperature. Oil temperature gauge is a relatively recent addition and gives something extra to worry about. To be fair, 135 C has only been seen on the track with sustained full throttle and 4500 - 6500 rpm (rises from 60C to 135ish in 15 minute session and still climbing!). I’ve not seen it above 120C on the road and that wasn’t in the UK. UK use max seems to be about 110C, which is why I’m resisting an oil cooler. Not much room for one on a Vitesse anyway - considering ducting some airflow to blow over the sump as it’s tucked behind the x-member. The exhaust collector being almost in contact probably doesn’t help either! Link to comment Share on other sites More sharing options...

blubayou Posted January 20, 2021 Report Share Posted January 20, 2021 Just to clarify, the 4 cylinder equivalent is the Mann W713 / 14. Been using these for a few years after a trusted recommendation on here. As above, bulk bought from ECP a few years back. Link to comment Share on other sites More sharing options...
