I think it had been going for some time as iv done mallory park two times the first time I did see the oil presser moving about a bit so I had been keeping a eye on it about 6 weeks later we did mallory park again only because it's just down the road from my partners house any way it did not seam to bad that time but saying that it was a colder day and I was not out on track as long each time as we kept having problems with boost pipes . Then come Bedford all good all day but I had said the car had a bad vibrashion at top end and it was struggling to push throw it so I was watching the oil presser as to be onist I fort this was coming . As it's only running a standerd pump
Cold 60 psi tick over
Hot 30 psi tick over
Hot 50 psi 2500 rpm
So you can see I now it's day was numbered
Still most of the part are in the post now on there way to me and the crank goes in today for the regrind
