Oh yeah Defo agree it's not right. I was just commenting that his bearings where fine and it was the pump everytime causing the low pressure.
He didn't get to the bottom of the issue which is a shame.
I got the sump off, small particals laying in the sump, very few of them. The oil that's in the sump and oil filter is NOT gritty to the touch, after running plenty of it through my fingers I've not felt any grit.
The crank doesn't move in and out that I could notice with a pry bar.
The rods have side to side play though? Like I can wiggle them with my fingers.
The engine doesn't seem to have very strong compression, it turns over real easy by hand and you can hear air rushing out. Faint petrol smell to the oil aswell, Think that's what my black oil is about, on power stroke it's leaking carbon etc past the rings and into the oil but it isn't bad enough to let oil back past to send it through the exhaust.
Probably all the idling I had to do when it was first started, rings haven't set aswell as I'd of hoped but that's not massive issue just yet, I'd happily run that for this season and rebuild it over next winter, missing this years track season is not an option for me. I'd rather build it again next winter if I can.
At first I thought the crank was jumping around because the inside of the block looks like it's been hit/scored but I can't see anyway that's possible, the cranks in tight and there aren't any markings on the rods or the bolts etc to prove that.
I've not taken any caps off yet, I wanted to check what the torque settings where for each of them first, to check they are still tight.
I think I can see scoring on the pump through the oil pickup hole, Yet to confirm though.
The oil pickup had come into contact with the sump it would seem, shiney dot on the inside of the sump and a shiney spot on the oil pickup.
Pictures will come but obviously I've got to try and diagnose this all first.
Either way looks like I'll be building it all again, if not now then over next winter.
On the bright side the learning curve is still steep, we love abit of learning!
Shame I have to do it the hard way everytime lol
Edit: found a chunk of piston in oil pickup mesh(tucked in the rim) Don't worry it's a cast piece, must have missed it when I cleaned it out the first time! Hopefully a piece didn't find the oil pump. Also afew bits of blue roll in there aswell. Lesson learnt to be abit more vigilant with the cleanliness. I'm not convinced that's the issue though. I want to check the cranks straight and the bearings are clean first.
