Thread: Bypass Oil filter spin-on adapter.

I understand why a spin-on full-flow filter cannister is used in the conversions (convenience, availability, cost etc.) but is it the best thing to use ? Only filter a percentage of the oil (as per original) but filter it at a coarser level (not as per original).
I realise that the original bypass filters are slightly less common than rocking horse poo so something is better than nothing but bypass filter systems are readily available so maybe a better solution would be to base a conversion on a readily available bypass filter element ?

Just my thoughts.....

Interesting read. If it can use a Franz roll how is it better than Franz.
What is the difference?. I heard that roll filters were not highly regarded.

I don't think he is saying his filter is better/worse/different than Frantz, it's just that you can buy his filter assembly & use either his or Frantz filters.

Father-in-law talks about them being a very common fitment on trucks years ago. He always refers to them as 'dunny roll filters', if you read the Frantz info the original patent was based on using a dunny roll but they now use purpose designed filters (that look like dunny rolls !)

This one takes the place of a spin-on filter so might be a better bet for a conversion.
Not sure how they can put a fine filter into a full-flow application though....it might put extra load on the oil pump. OK for a bypass application.

Hi All

Most engines keep the oil circulation within the confines of the engine itself.
When these filters are added to those motors, you have opened the oil way to devices remote to the engine itself.
Unless the installation has been done properly there is a chance that a oil line could fracture and dump all of the oil, not good for long term engine life and defeats the point of fitting those filters in the first place.

To get the best out of these filters the installation needs to be done to a high standard.

Getting back to the series one motors, the original design of that motor before it was thought of being fitted into the 80", had only the oil strainer for the pump pickup, built into the side of the sump, made that way so that at the time for a oil change, it could be unscrewed and pulled out to clean, the bypass filter as far as I know, was only started to be fitted to Rover engines ( P3 Rover ), just prior to the development of the Land Rover.

Has anyone fitted a filter into the oil cooler lines of the 300TDi ?

And if you get caught short, you always know where there's a spare dunny roll!

Do you know where I can get one of these adaptors i've been looking every where on the net & cant find them . Wayne

I still play with by pass filters in the old pieces of junk I am often asked to work on.
Ryco Z8 is a spin on filter with the restrition built into the spin on filter itself.
That means a common and easy to get Z9 oil filter remote housing can be used.
Dont forget holden grey motor oil filter kits used R3P element type filters and housings and they are still advailible.
The WW2 jeep used a slighty larger R4P element and housing and WW2 jeep stuff is advailible new and is usually cheap.
Diana if you drop into work I can show you a continental F227 motor with a R3P filter and housing bolted to the cylinder head........interestingly the same motor can be fitted with full flow filters too.
Also my 1960 jeep with IOE motor is running both standard bypass R3P mounted on the cylinder head and a full flow Z9 mounted on the fire wall.
