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


How quickly would it fill up??
My catch can only ever had moisture in it. Do you have breather lines of the back of block?
 
The b16b would fill the can up in around 25mins.
I've got breathers from the back of the block and front of the cam cover.4 in total. One of the block vents I've got doubled as a drain back.
The can is very small, around half litre, it's one of those things I've had on the list to change but obviously had more important things to do.
 
I'm on my 4th engine and none have ever left a sign of oil in the can.

:-s
 
Seriously small issue in the grand scheme of things. Never left any oil when n/a but turbo is when it started.
 
shouldn't be getting that much oil in a breather can, my b18 turbo like the others doesn't have anything but condensation in it. May seem like a small issue, however if you're getting oil 'loss' into the catch can that may be an indication of your oil pressure loss too
 
Seriously guys, not that big an issue.
I'm draining back so I'm not losing anything from the sump.
Could be my setup being quite small not helping aswell but that's not what I'm needing to know about other issues more importantly.
 
I've been doing some research for you jessiej, as far as I can work out the oil colour has nothing to do with its effectiveness. The dark colour which contaminates the oil is soot and the likes.

You say "not a big issue", infact it is almost a very big issue, you are running forced induction which of course will increase blow by and also crankcase pressure, this does not automatically mean that filling your breather/oil catchcan with oil every 20 minutes is normal.

I run a 13;0;1 compression 1.9L engine that revs to 9000rpm with 4 breathers and the resulting 'blowby' is very minimal, increased oil in the catchcan is related to compression and health of the engine, if your car is blowing alot of oil through as mentioned above is a very bad sign.
 
Thanks for takin the time out to research for me, nice of you.

I could argue mine sees higher cylinder pressures than yours though but let's not go there.

It can stay " a very bad sign" for now then.
You guys are going on about abit of heavy breathing like the engines never going to run again! Lol sure abit of blow by, I already know this.
The oils black because of the blow by, found this out yesterday, obviously its trapping soot etc in the oil.
B16b did it aswell, this is only on track btw. I'm not talking about driving normally.
It doesn't burn oil so the rings aren't THAT bad. Probably bad run in procedure like I've already said in my build thread. Didn't have much choice but **** happens.

To me a very bad sign is low oil pressure.
Which is the issue Im asking of.
Abit of blow by isn't going to harm anything? Won't see a bearing mash the crank because of some oil in the catch can! 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.
 
I will put money on it that it's just the fact that the pump was not pre oiled put a new one on there and of you go (flush the engine first:nice:)
 
Going to do the same thing as you did, engine lube the gears this time.
We live and learn don't we.

Forgot to reply to this.
Try running without the breather running from the alternator side of the block. Im sure I have read somewhere this one can cause the can to fill up quicker. Might be talking pie in the sky, but it is worth a try.
 
I'll give that a go Murray. For a test on track I can just block the line with a bolt or something and see how it goes.
New pump on the way and exhaust silencer.
Should be back up and running in about a week or so.
Next trackday is brands april 13th.

I've it some sae30 Classic mineral oil I used to dip bolts in before tightening(rod bolts and head studs) this will be ok to put in as a flush right? Run it up to temp and then drop it out and replace with the good stuff?
 
Valve cover breather setup. Try two from the valve cover and one return. Return should be one of the points next to the oil filter [B series].
 
I've got two in the cover and two in the block.
 
This shows the two points that I would access for a return, the -10AN fitting.

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

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