that's the only real way , by unscrewing you pressure sender and connectioning a MAC gauge. Good luck.

I`m thinking scratchchin If the shells have shown wear then what condition will the cam ,cyliders and top end be like ..

I could have a knackered cam ,scratched bores ,burnt out pistons and worn rockers !

I`m sick and tired of TVR ownership furious

I wanted to have a new carpet and tidy up the body a bit ,that looks like it not going to happen .

Daz, get a full report before you open your wallet.....a "new" engine might not be too much more.

One tiny area .
I still don't get this.. yes.. it will blow only in 1 tiny area... the weakest area... but you'd need a few hundred PSI to bend the metal lip out!... who fitted the filter... It's been done wrong??... arn't they responsable for this ? rolleyes

I once had a h/c oil pump on a Ford engine that blew the seal out of the filter when the pressure releif valve jammed.
It emptied the sump very quickly!!
I hope it isn't as bad as it seems Daz.
I would be tempted to replace the shells and run the engine for a few minutes on some cheap oil and then drain it and change the filter again.

Update on my pressure drop probs,
Fitted a mechanical gauge, held 25psi at tickover and 50 psi at 4500rpm with no pressure drop, immediately refitted the electrical sender and performed the same test and it was back to pressure drop at 4500rpm so its electrical and at least not a pressure problem with the engine

Ahh, that's good Rich, Daz I'd do as others have said regards shells, the crank is probably ok mate, soon as it's running I'd do a compression and leak down test and go from there.

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 .

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 .
Didn't centrals fit your new diff? They would have to remove the exhaust first so surely they would have seen that your oil filter was not square onto the face , or was leaking oil?,
as they would have been in that area undoing the exhaust clamp from underneath the engine. I would say it would be pretty much impossible to miss? Just asking a question?

Got my car back , I had a new oil pump the front cover was damaged on each side of the pump so it had to be flattened off . The big end shells have been replaced ,there was only one shell showing a small amount of wear .

I had a new clutch slave cylinder and a couple of cheap oil flushes then Millors 10w60 sully synthetic and a fresh filter .

The Racetech oil pressure sender had failed so that has been sent back and a new one from TVR Power .

His pressure test rig was showing between 30 and 60psi and the new sender consistent to the test gauge .

The front cover was removed ,we looked at the oil filter fitted and there was nothing stopping it being screwed fully in ,it`s still a mystery why oil the fell to the floor in a few seconds .

Its cost me a packet mad That was my carpet money !

glad your engine is ok. Just a word of advice though. Try to stick with the same TVR specialist to do all your work. They will get to know your car between services obviously enough, and it all goes down on your duplicate service service records that the garage will keep. So they will get to know your car inside out and what needs replacing and checking , everytime you drop your car in to them.

Yes i think double that and the parts came to around £400 .. They probably reduced the labour by half .

Result, more money than you wanted to spend, but a lot less than it could have cost.
