Oil filter

[davidwheeler]

The oil filter drains when the engine is not running leading to that agonising wait on starting for the oil pressure needle to move.
Is there any  way to prevent this?

Have you heard of an Accusump? It's a bright blue anodized cylinder that stores oil under pressure. Connected to the engine via an oilway or a sandwich plate on the filter housing it can be triggered by a switch prior to startup to pressurise the engine and reduce start up wear. If you suffer from oil surge/starvation with low pressure during running the Accusump adds oil to the engine and, when normal oil pressure is restored then oil is pumped back into the Accusump ready for it's next call of duty.

Made in the USA it is available here and comes in various capacities - 1, 2 or 3 quarts.

I am in the process of fitting one during my Beta restoration.

If you order one please be aware that the valves come in manual and electric and have different pressure ranges. You would want one that triggers automatically when the oil pressure drops below normal for the Lambda.

I am not sure an Accusump works with older style engines where the oil pressure is dynamic i.e increases with revs, where as a more modern engine such as the Lampredi Beta engine the oil pressure is pretty much static at above tick over revs. I would be interested in views on this.

O wata na Siam (as I was told to sing in Junior school as the Siamese national anthem)      What I thought was zero oil pressure was in fact the needle going whizz round to the stop at maximum!       The problem does not exist - or it does but usually takes only a few seconds for the pressure to come up.

Same with mine .... caught me out as well

Just changed the oil, all 6.5 litres of it ! At 10€ plus/litre it's not cheap .....

What are you using?  I have used 10/40 semi-synthetic for many years, together with the modern paper filter it works very well indeed and helps in the cold winter.
When I stripped the VIIth engine to repair the block there was no wear at all on the white metal bearings even after 28 years of pretty frequent use and a number of continental trips.

I've just filled up with 20w60 Penrite "Classic Light"

Also I'm going to leave the undertray off for a while to see where the leaks are ...... not too bad but will be nice to know and it gives me an opportunity to clean it all
