Hi Colin,
That's a good point actually, the engine was freshly rebuilt by the previous owner but of course I can't be certain what he has actually done to the engine. I'm sure the jets on my engine should be 1/16th so I'll measure some bits of wire and check that its a snug fit. I've been using a piece of guitar string to poke down the jets and I think its a bit thinner than that.
I haven't been able to get the car out for a proper thrashing down the road today as I've been taking it for short drives up and down the road while I try to sort out a couple of grabbing brakes. However I had the engine running for a good hour or so, driving it up to about 30mph briefly and the engine was hot enough to sputter some steam and water out of my ill fitting radiator cap (I may have overfilled the rad a little bit yesterday).
Oil pressure was around 2psi idling and a max of 8psi fully revved up. I will try removing the fan belt as suggested but really I think I just need to get it on the road and give it a good blast. The pressure definently seemed to be coming down with time, but it is starting to get bloody cold up here in the North.
As I said the engine was rebuilt recently by the previous owner and he has used Silkolene 20w50 classic oil, and supplied me with some to use with it. I've looked at the specs for the oil and it seems to tick all the right boxes. I'm wondering if this is perhaps too thick for the time of year. I might have read elsewhere on the forum people prefer a lower viscosity oil in their 7's
