What should the oil pressure be in a Jaguar?

What should the oil pressure be in a Jaguar?

Now I have great oil pressure! I have adjusted the pressure relief valve to limit max pressure at about 60 lbs. When the engine is quite warm and running at idle, the pressure will stay above 40 lbs. So, what’s the problem?

What kind of oil pump does a Jaguar 4.2 L have?

This early engine (before the revision at block G1906) was fitted with an oil pump that is not interchangeable with the later and much more available 140 pumps. So I had my machinist fabricate an adaptor plate to enable the installation of a more modern and much more available pump for 4.2 L engines.

How much oil does a Jaguar XK leak?

I know all XK’s leak oil but mine leaks more than most. I lose about 3 oz. per gallon of gas with average driving and slightly less on a long trip. It loses a lot out the slinger when it is shut down because the engine has about 170,000 miles on it.

What kind of oil pump does a 1955 Jaguar XK 140 have?

I recently completed rebuilding the engine from my early 1955 XK-140. This early engine (before the revision at block G1906) was fitted with an oil pump that is not interchangeable with the later and much more available 140 pumps.
