Hey,



After changing my oil just 2000kms ago (first change since rebuild),

i checked the oil level yesterday.. and its down to the "low" already..



Is amount of consumption normal? my motor is completly standard

It should consume a quart every 1500 miles or so once properly broken in. When freshly rebuilt I think it consumes more but Im not sure on the exact amount. Im sure someone around here will know.

With a leaky oil cooler line right now, I lose about a quart every 300-400miles....the leak isn't THAT bad, some of that is consumption...its a newer SP engine with ruffly 7500 miles on it. Before this motor, my other had 160xxx miles and it didnt burn a drop...so you never know.

so your other did not have any working oil injection?

if you have the metering pump wired open, it will burn more oil than normal.

My oil cooler lines seap a bit too. I plan to replace the copper washers next time I change the oil.

seems to be a little much to burn on a rebuild. maybe the metering pump

no OMP, block off plate on mine. On my old motor I was running stock OMP, it ate up a little..but you

hardly noticed it..nothing like my new engine...I'm pulling it apart again here soon anyway..

mild streetport sucks! Heavy is next... https://www.nopistons.com/forums/pub...#>/biggrin.png

Oh yea, and if the cooler leaks..or the lines...its really messy..can't miss it. my lines are covered in oil..and they dont even leak THAT bad!

replacing oil cooler and oil cooler lines would cost about how much?
