Or a wiring fault dont run it till you get an independent gauge on it 1st 
if its the bearings then there is a good chance your oil cooler fault as dumped oil previously (this being the case your arse needs kicking) no engine will tolerate oil pressure failure for long 
stay positive
I did not fit the oil filter ! if its the bearings then there is a good chance your oil cooler fault as dumped oil previously (this being the case your arse needs kicking) no engine will tolerate oil pressure failure for long stay positive Sardonicus said:
nlikely on the Serp front cover IMO and then you need to ask yourself what contaminant as caused the valve to stick open 
unless the releif spring as broken (possible) still its worth checking whats to lose? but Daz let someone else do this because in situ compressing the cap & seating the retainer/circlip will be a swine in situ and if I was this far I would be removing the sump and checking pump pick up security etc etc I would also knock the oil cooler out of the loop incase one of the cooler hoses have collapsed internally 
wouldn't be the 1st time ......
I contacted Mocal regarding the problem with the oil filter catching the the nut which holds the stat in ,they said if the stat fails it is impossible to starve the engine with oil. If the stat fails it just goes round the engine . unless the releif spring as broken (possible) still its worth checking whats to lose? but Daz let someone else do this because in situ compressing the cap & seating the retainer/circlip will be a swine in situ and if I was this far I would be removing the sump and checking pump pick up security etc etc I would also knock the oil cooler out of the loop incase one of the cooler hoses have collapsed internally wouldn't be the 1st time ......The guy at Mocal seemed very concerned regarding the problem . The nut should not be anyway near the oil filter .
What is a the relief pin and what could be stuck ..?

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 .

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 .

So the filter fouls the nut, so not sealing, ok so you blow the oil out.
Why have you been loosing pressure since, something's not right, put that right and your engines saved or have you been running it with low pressure, is the engine sounding metallic!
That sandwich plate, am I thick or is that nut fouling simply because it's not able to turn a bit more. It's a disaster waiting to happen, what a pathetic design or have I mis understood? That nut would foul most filters FFS.
I can't work out who's screwed up here?!!
Is the plate bespoke or ripped from some other application, shaving edges off a nut, I'm well confused?!!
I did not supply or fit the oil filter ,its down to the fitter to choose the correct filter and fit it properly .. I know mistakes are easily made but .Why have you been loosing pressure since, something's not right, put that right and your engines saved or have you been running it with low pressure, is the engine sounding metallic!

The oil filter was not leaking until it let go then the lot went in seconds .
The oil filter was not married exactly to the face of the sandwich plate because the nut was pushing against it .
The guys at TVR Central who investigated it found the problem . They said there is no way they would not of seen the problem ,you could see the problem ,i`m surprised it was noy picked up when fitting it .
TVR Central are nothing to do with the problem ,they simply helped me after the disaster .I just happened to be there when it happened .

Not defending anyone here Daz but, your car is not standard, the mechanic would choose a filter for a standard car, as you said it wasn't leaking until it let go, so not apparent that there was any problem with the filter initially after it was fitted, once you change things from standard and fit sandwich plates and the like, the chances of things going wrong increases, like I say I'm not defending or directing blame towards anyone, and I hope its sorted soon for you.
It was fitted by TVR specialist .so no excuses . Mocal sandwich plates are used all over the world ,they are nothing special .If there were problems with the unit they would of gone through years ago .Edited by SILICONEKID345HP on Thursday 3rd July 22:58

I've took a job in a garage to bring me upto speed, specialists my arse!
Care and attention are what's needed as much as fancy full knowledge!
Someone asked me to polish an oil fiter because he's selling his eurobox, car dealer, punks half of em and I told him to ask someone else to do it,,,,,, he had the hump, he also nearly had a black eye, wker.
The real question is has any damage occurred to Daz engine?
I've been through a kind of hell with my Tvr, not impressed with the cars,
I feel Daz pain, you need a bottomless pit and zero brains to own the average Tvr, that's before you mod it.
Anyway, if Daz has saved his engine what should he be looking at other than taking it to Dom!!!!!!
What should his plan of action be, I'm assuming the plate/ oil pump is the issue?
Its going back ,sump is being removed and I will be there to see it . My friends dad who rebuilds diesels and sells vans will be taking it on his transporter.Care and attention are what's needed as much as fancy full knowledge!

I'd not take the sump off... its electrical... if it was actualy going to zero you'd know about it by now!... engines don't run long at zero pressure before they have done in the bearings... 10 secs at speed and its all over
.....anyway.. back to Daz.. any news yet
Waiting for it to be picked up ......anyway.. back to Daz.. any news yet
The plate which sits on top of the oil pump is scoured and the cover where it sits .. The crank shells have some scours which you can feel with your nail and in one area worn through ,i can see a copper colour metal .
The crank it self is fine .
The crank shells are on order with a new pump and pressure relief valve .The timing cover and plate is going to be cleaned up .
I`m not going to take any chances ,the oil filter will be secured via a jubbalee clip .
We can`t work out why the oil filter let go ,the filter does not foul anything when screwed in .
ll i can say is i could see the rubber seal hanging out the side of the filter .
This damage was caused by running with no oil for a short time then what made it worse driving back 78miles .
When i got home and turned the engine off then the oil pressure valve locked closed ,it was clogged ,blocked with something from the timing cover .
I`m feeling a bit sick .
