Sealing the oil filter bowl cover with silicon.

[fergycool]

I'm having trouble sealing the cover for my oil filter bowl (Perkins 4.270). The old washer is pretty shot. The new ones I've got with the filters are narrow and quite small. I just cannot get a decent seal.

I cannot source a suitable washer. It needs to be 83mm OD and 70mm ID. I guess the thickness is less critical but a few mm would be fine.

I'm thinking of making my own. Smearing a bead of liquid silicone gasket around the cover. Letting it go off then bolting down. I assume it would need to be replaced every time I change the filter. But that's fine.

Is that a daft idea or should I just persevere and find a suitable washer?

Thanks.

I was trying to seal a CAV filter and the ones which come with the filter are smaller than the original ones from 1984 so I put 2 in, one on top of the other. It worked otherwise I would have been looking at silicone.

Some years ago I had the same problem with the primary diesel filter of my vp 2030.
Each filter replacement were a torture
I simply couldnt get a seal without leaks.
The surface finish of the available glass gasket lips were irregular and not smooth enough.
Also the available seals were not dependable
Sometimes the normal vibration of the engine promoted a minor displacement of the gasket generating a leak.
Finally I decided to use a filter unit without glass. During the last 6 years I am using a gas oil filter MANN WK 836 or a Bosch N 4106 and are very happy with it.
Now changing the filter is simple. done in seconds, just lubricating the seal and screwing on the new unit

good luck

Junk it and get another one?

There is a screw on conversion kit for a similar engine (none for this one) from Lancing Marine for £48. Perhaps I should go for this.....!

I've said it before on here some of the non branded filters are rubbish. They are cheaply manufactured and the sealing faces are too small and / or not true. I had to junk a box of 12 filters I bought of eBay - I know, it know! I just couldn't get them to seal. I then used a genuine Fram and got a seal straight away. Having said that it racks me off that they only supply two, not three big seals with the filter and despite their widespread use the design is nowadays crude at best. I'm fitting Racor spin on filters next winter.
