There must have been symptoms of low oil pressure before it started knocking ?? There no way it will just go instantly ??

Lol no there was nothing, and I mean nothing. I was told that the gauge was reading 1/2 a bar lower than showing when checked with mechanical gauge. So fiat gauge shows 1bar at tickover, and mechanical 1.5bar. That's it.

Here is a vid

Was it warmed up to temp properly, before you brought it the oil temp needed to be really hot around the 80c mark before it would show on gauge properly .

Yep it sounds shit terminal

Yes been driving for 15-20 mins.

1 bar on hot tickover is far to low for 20vt you should be around double that for a healthy lump and the seller would have know this and should have told you buddy.

That bloody car is cursed

Didn't realise it was this one you enquired about Anthony .

On the plus side, You appear to have an M5 Tourer, So sod the coupe & hoon that around all night!!

now that is an understatement

If it has got to have a replacement engine I would get the car taken to a specialist and have it installed and before that have the front chassis legs, outriggers and cross-member refurbished so you can make a totally mint coop.

There's a forged block for sale in the for sale section. You could whack that in and then you have the pleasure of the options that go with!

Sorry to hear it's bust, good luck with it!

As much as this is a complete pisser Nismo has offered to refund 90% of the money paid once the car has been returned. Just need to wait for the V5 so we can sort.

So agreement reached, problem solved.

Good on you both for sorting this misfortune out sensibly.

Wow - good on him.

real shame about the car (think i have a mag article on this one?)

decent outcome reached by reasoning and fairness from both sides - admirable by you two.

Well played chaps.

There are some decent folks out there then good choice

Judging by the amount of posts the search bar turns up on the topic of "Oil pressure fine then suddenly metal on metal BANG!", its a perhaps a bit harsh to assume that the seller knew...

The car looks stunning so really this is a proper excuse to forge the internals and make her surely one of the best examples of an LE in the country

All a complete surprise when it was a "kent" car, but a great example for all to see an arrangement made which sounds acceptable to both parties
