TR6 TR6 oil pressure

What should the oil pressure read when the 6 is warmed up and at idle?

After a spirited drive of at least 20 minutes in warm weather, around 20 to 25 @ 900-1000 rpms should be nothing to worry about

Thanks, I was a bit nervous with it at 20, at a cold start it's around 70 sound about right?

I'd say so. Cold start up doesn't mean much, at least to me. What is it at 2500 rpms about 20-30 minutes into a drive ?
Also, what oil and weight are you using ?

I am using Castrol 20/50.Also what is a good dashpot oil for the stromberg 175cd carbs?

What weight oil is recommended? Is the Brad Penn oil that much better?

People seem to think highly of Brad Penn oil.
Sundown are you familar with the ZDDP "controversy" ?
If not I'm sure you soon will be.
No doubt in my mind that a ZDDP component in lubricants is needed during the break-in process of a new camshaft and probably for 500 miles thereafter.. Whether or not it's still needed after the cam lobes and tappets are burnished during their mating process remains questionable in my mind.
However I still use oil that still contains ZDDP since I can find Valvoline VR1 20w-50 locally and on sale frequently enough where I pay a little over 3 dollars a quart.
There are supplements that contain ZDDP if you have a supply of regular Castrol 20w-50, such as blue containers of STP or Rislone with added zinc.

Dash pot oil. Well I use a special concoction, the major component is Bars Rear Main Seal Repair Oil.It's about 30 weight and I use it to keep the damper well's O-ring oil seal lively Straight is perfectly fine, BTW. I use a concoction with 3 in 1 oil or Marvel Mystery Oil @ 20%
But for simplicity sake just using whatever you use in your engine is fine too. It only takes 3.5 cc's per carb.

While there is nothing noted for oil pressure at idle, the Haynes manual for the GT6 & Vitesse (the 1.6 and 2 liter version of your TR6's engine) says: Normal oil pressure at 2000 rpm...........40 to 60 lbs.
