View Full Version : What spin-on oil filter do I use???

09-14-2006, 09:16 AM
I just received the spin-on oil filter adapter from VB, p/n 17-240, for my TR4. I just don't know what oil filter(s) I can use. Can someone enlighten me and if there is anything I should be aware of when I install the adapter?

.............Cheers, Alex

If its the same kind as for the TR6 I use a Fram PH3600.

Hi Alex,

The biggest problem installing one of those adapters is getting a really good seal under it, where the oil cannister originally seated into a groove in the filter head. Perhaps the most important thing, just as with that original cannister, is to make sure the old square-sectioned rubber sealing o-ring is removed before installing the new that came with the kit (forgetting the old one in there and accidentally stacking a new one on top of it nearly always causes heavy leakage). Also check that the adapter is seating squarely within the groove and not hung up on any edge.

I think those adapter kits sometimes come with two different center post adapters, because TRs had two different filter heads with different threads there (Teculmet and Pur-O-Later, if I remember right). One or the other of the adapters will fit. Just be sure to use the right one.

Also, those center posts of the adapters are usually brass, so be a little careful not to overtighten and break it.

I think the Fram PH3600 (and it's equivalent in other brands... I use K&N HP-2005) is pretty standard for these adapters, but to be absolutely certain you could take the adapter with you to the auto parts store.

Oil filters are much more standardized than people tend to realize. The industry seems to take great pleasure in serving up a huge range of filters and printing up thick catalogs with very specific application info. The primary variables among filters is the size of the threaded section and whether that thread is metric or SAE, plus the diameter of the sealing ring on the filter. The only other key consideration is the length and diameter of the filter cannister itself, if it will physically fit in the space available in an engine compartment. TR2/3/4/4A have lots of room in that area and can actually accommodate all sorts of filters.

Once you have determined which of the center posts will be used on your car (compare with the bolt thread on the original TR fitler cannister), before installing the kit just take the adapter parts with you to the store. There you can simply test fit to your heart's content, checking various filter's threads with the adapter post and comparing the sealing ring on the base of the filter to the flat area of the adapter it needs to seal against.

Will the Fram PH3600 also fit a TR3 with the spin on adaptor?

I got the spin-on adaptor from Moss for my TR3, and it came with a Fram PH3600.

Recommended best filters are Wix 51516 aka NAPA 1516.

These also fit: NAPA Gold 1034, Wix 51034, Fram PH2825, K&N HP1002

Make sure that you remove the old o-ring as Alan said. Common source of leaks otherwise.

Thanks everyone. The conversion went very smoothly, and no leaks........yet. The old o-ring removal was a great tip. It would be easy to miss it. Thanks again.
