Title: Oil filter Post by: pakelaan on April 13, 2018, 11:53:58 am For my Gamma Berlina 1981 I bought a couple of original oil filters a few years ago. They are all used now and because I could not find the original ones, I bought a Bosch filter. The size is different: it is smaller and higher, which causes it to contact the steel feather/spring from the clutch. It fits if you push the feather a little bit aside, but it is not like it should be I guess. Does anybody have tips, e.g. another aftermarketfilter that is similar to the original size? Is it a problem to use the higher type? Kind regards
Title: Re: Oil filter Post by: Theo on April 13, 2018, 09:30:14 pm Alternative oil filters is a common discussion topic amongst Gamma owners. The original Technocar R71 is probably the best. I have tried most of the alternatives and I found that the Coopers Z509A is by far the best alternative. Other alternatives are FIAM FT 44875 and TJ FB2086. In theory any filter for the Daimler/Jaguar V12 engine should fit the Gamma but not all have anti-drain valves fitted.

Looks like the Mann W930/13 is the same. Anyone able to confirm suitability? Title: Re: Oil filter Post by: Theo on August 07, 2018, 09:35:50 pm I still believe the Coopers Z509A is the best filter for a Gamma. Geoff used to have a few and said a while ago he can always get them so give him a call or drop him an email.
Title: Re: Oil filter Post by: Theo on August 15, 2019, 10:36:28 pm I changed the oil and filter in the Gamma today and as I couldn't get a Coopers Z509A anywhere, I went for a MANN W930/13. Meant to fit the Rolls Royce Corniche 6.9 litre and listed as a direct replacement for the Coopers Z509A as Harvey has reported further up this thread. I haven't driven the Gamma any distance yet but so far it looks OK with the oil pressure light going out quickly on start-up.
