Rebuilt engine, slight loss of oil pressure plus other symptoms.

Already got them.
One closest alternator is my drain back.

I'll take it as no one has any idea about the oil pump?

Your pump ate metal, something not right on your build.

Haha I know this!
The whole reason for this thread is to try and find out what, everyone's jumped on the breather wagon like that's more important lol

So back on topic, took the pump off and it looks like this

The gears are all pitted aswell so that's why my oil pressure is low.
Now to find the cause of the pump failure. Either it's sucked up crap from the sump, ran dry from cornering or the cranks bent right? Can't think of anything to cause this.

I've got a weld in baffle in my sump and never had this issues before so I think running dry is unlikely. Although from research it appeared @tama666 had this issue with weld in baffles and changed the pump and sump and ran perfect since.

Personally I think cranks to blame but can't be sure yet.

My issue was much the same, the pump ate metal on the B series. It was really due to a poor weld job on the pan baffels [used part]. I then put in a morosso pan... Do you know where the metal came from that killed your oil pump?
 
Have you cut open your oil filter yet? Was there more metal in it?

It's clearly picked up some ****, the fact you found a piece of piston in the pick up tube would be enough to confirm it I'd say.

Turning it over with out any lube would not of done that sort of damage, the most damage that would do is some scores/scratches,
something's been mashed around that pump

Something really bad happened. You should open it back up to find out what is being eaten up.
 
I found a piece of metal on the sump plug on the oil change before the trackday. I'm not sure where it came from which is a concern.
Swarf could have fallen out of my new cam cover(had breather ports welded on)
I'm yet to check the filter or the cam cover for any signs of swarf/metal.
The oil pickup had been in contact with the sump, the sumps got shiney marks on to proove that.
Sumps not been hit by anything so not sure what's happened here either?

I can't just buy a new long block, I'd have to rebuild that again with my Pistons and rods
 
So everyone here is thinking the pumps eaten metal through the oil?
Going to fit new pump, clean everything up beat I can and flush the engine oil. Replace and pray lol
 
Thanks bud.
Just seemed strange the engine ran great until the trackday.
Time will tell I suppose, thanks for everyone's input. Will update later
 
Tbh I wouldn't even bother with classic car running in oil, Just use some cheap cheap semi flush it out a couple of times. Before sticking in your normal stuff. Providing you lube the bearing before hand and prime the pump a couple of times before sparking.
 
It's just beause I've got it sitting there and saves me buying some.
Will report back once I've sorted everything out.

You have to sort the clearance between the pick up pipe and the sump also!

I'm a little worried about this on mine. Fitting a type r oil pump to a b16a block gave me issues fitting the sump on over the oil pick up.
I've seen ALOT of smashed in oil pick ups off Hondas though where people have clearly had this problem and had to squash it in and they haven't had any issues?

What's the idea here? Try and bent the bottom of the sump down to give clearance? Or new sump?
 
Use the correct pickup for the pan that you are using.

I am.
Both b16b parts. On a b16b block....

I've seen this issue kill many an rally engine!

It must of had a thump at some stage to be so tight, you'd want to double check the the sump is flat and that the dimple for clearance for the pick up is deep enough. In the rally cars I weld a 3mm plate and braces down the sides of the sump to stop this happening!
 
Change the filter aswell Jesse, then investigate the old one.

Out of interest did you check your ring end gap whilst inserted inside the cylinder bore?
