What I want to know who fitted the oil filter ?....
Your problem is not the stat or f
k all else except the seating of a oil filter that was ok before the oil change ?.. Come on daz your a plumber apply a bit of fault finding diagnosis !, I have the same mocal set up as you and don't have a problem, the oil filters do vary and I can only manage to fit one type due to the filter fouling on the cross members of the chassis. Other that that's it , unless who ever fitted the mocal plate didn't tighten up the oil pipe fitting enough onto the sandwich plate or didn't check the orientations of the -dash fittings.
The edge of the oil filter was wedged against the nut making the oil filter not sit square . The rubber seal on the oil filter was hanging out on that side . Your problem is not the stat or f

The guys at TVR Central cleaned it all up ,found the problem and used a belt sander to take some matarial off the corner of the nut .They did not want to try and tighten the the nut so went for sanding it down
He had the same problem with a genuine TVR filter as it was only just touching when fully tight but the one supplied and fitted had a much longer lip .
They fitted a new oil filter and fresh oil . The gauge read a little lower than normal and there was never a light on .i drove it back with no problem ,showing up to 40psi .
The next day i started the engine and this is the problem i have .
Daz in all honesty if it was terminal the big ends would be rattling (the RV8 does not hide this fact/noise well) and less likely the mains grumbling/growling GET IT CHECKED OUT BEFORE DRIVING IT 
I reckon it will be OK 
but stop running it until you get get an accurate gauge on it and are certain its a pressure fault like you have been told over and over and over and over again 
and remove/bypass the cooler just for testing i.e screw the filter straight onto the front cover like TVR intended otherwise your just adding links to the chain

Hope it`d nothing to do with having the Mulfab sump fitted .

Thats a thought did you have a different p-up pipe fitted with this sump? if after the mechanical gauge test it shows low then I would be heading straight underneath and pulling off that sump 
a mate of mine years ago put a rebuilt RV8 into a Capri along with modded sump and p-up he was plagued with oil pressure problems till he was advised the pick up may be to close to the bottom of the sump thus restricting flo his ever resourceful Dad quickly put a large G clamp around the sides of the sump and tightened it till the base bowed out for diagnostic purposes and yep the gauge quickly shot up nice steady oil pressure 
needless to say said conversion company got an earful the following day 
not saying that's your problem but if the gauge test dont bare fruit thats where I would be looking but not before screwing a branded oil filter straight onto the front cover (no sandwich plate) 
Sorry to hijack (happy to start another thread if required) but I'm having an oil pressure issue too. Well, not so much an issue but a change from normal.
Basically the pressure has always been about 50psi under load and 30psi off load and has always been consistent. The last few hundred mikes had been a bit different though - 40psi under load and about 20-25psi off load. When it's off load the needle bounces around a bit as well, from around 15psi up to 30psi. Any particular reasons for this? I'm hoping it's just the sender!
Can an oil pump on it's way out cause this kind of symptom? Slightly lumpy idle as well, but could this be the cause of the pressure bouncing around?

id you not read my last post Daz? Alex is giving you a method of testing.
I did not fit the sump and did not do the oil change ,I paid a professional TVR trained specialist ,so it needs to go back to him .If the the oil pressure is low i am going to dump it outside with a solicitors letter .

I had a sender go wacky and read very similar reading, good chance it's goosed.Basically the pressure has always been about 50psi under load and 30psi off load and has always been consistent.
