View Full Version : Spin-On Filters

08-16-2004, 09:31 AM
I'm thinking of converting my GT6 to a spin-on oil filter. Is there any downside to this conversion? Is the oil flow maintained at the needed level through the adapter? Finally, I've seen others install this conversion with the filter pointing up in some cases and down in others. Any recommendations on this?

Planning on doing the same however on talking to others you get a pro - con debate, the normal filters are not as efficent or as good as cleaning the oil as the cartridge we have on now. Mine is on back order because there was a very bad casting problem and the suppliers had to pull them all,(sorry don't know the brand), one user of a spin on mentioned something about a small gasket that is no longer supplied like with our cartridges and you can get leakage, (more than LBC normalities) good things are not having a whole litre of oil go down your arm when changing the cartridge or fiddling with the gasket and not pinching it so you get a major leak. Even though mine is on back order and not here yet I still have not decided, will do some more asking and will view this site to help make up my mind. Thanks for asking this question. /ubbthreads/images/graemlins/thumbsup.gif /ubbthreads/images/graemlins/canpatriot.GIF

I generally prefer originality but went with the spin-on adapter on both TRs... just had enough of what I called the 'Capt Hazelwood Oil Change'.

Was easy and trouble free though some have had leaks the first time around. Be double darn sure you get the old gasket out of the housing/head. You may find 2 or even 3 old gaskets up in there. I used a mirror and a dental pick to get then out and cleaned it up nice... then Hylomar and one new gasket and the adapter sealed up fine.

Don't know of a downside -- can't comment on the up or down orientation as I think this is a 6-cylinder thing.

Nice touch to paint the spin-ons to resemble the old canisters -- looks better than having that big orange (or whatever) thing hanging on the engine.

George/Larry -

Thanks for the feedback. I know for certain that I only have one gasket in there now because I have done all the oil changes since the rebuild two years ago. I've even figured out that an ice pick is the ideal tool to remove the old ones - just skewer the old one and it pops right out.

If anyone else has any thoughts on who was selling the bad castings, I would be VERY interested in hearing about it. I'll certainly give it a good once-over before installing it, especially since I'm planning a long trip in the car starting this weekend.

George, what's the farthest south ski resort in the US? It's at the top of a great TR road, isn't it?

The only down side I have heard of was a friend who DID'NT
use locktite, the adaptor worked loose over time causeing a severe oil leak(which he was lucky to catch in time).

That's it. That road was used for one of the few TV commercials Triumph ever used... shots of a TR4 winding up the Catalina Highway. Still photos of it are in Mike Cook's book, but I sure would enjoy seeing that commercial.

If the filter points up the oil will drain out of it back into the sump, then when you start your car the oil pump spends the first few seconds refilling the filter canister instead of oiling your bearings.
You would overcome this by using a filter with a flap inside to prevent oil drainback, but these may be more expensive or less readily available, so I have personally never seen it done that way. The filter my adaptor uses is a 3600 series which fits a number of modern cars including Escorts and 3.0 litre V6 Taurus, so is cheap and common.
