I got a 95 civic hatch with b20 turbo swap, once and awhile i will have a lost of coolant (not much) and i have to add about a quarts or two of oil about once a month, is this normal for a turbo motor? from what i seen their hasn't been any smoke coming out of the exhaust.

2 quarts a month. thats alot
hows the blowby?

i never saw smoke on mine till i opened it up

Oil consumption, to a degree, is expected on a boosted application. Loss of coolant is another story. Cylinder leak down test might be a good idea, or at the very least pressurize the cylinders and check for coolant bubbles indicating a headgasket seal concern.

i'v pulled the piping off before and their was at least a layer of oil on all the pipes

my motor smokes more than a burnout, i only lose about 1 quart a month. unless you open it up all the time

sounds like turbo seals leaking oil

VTC_CiViC

Again to a degree, normal. Factory PCV system wasn't designed to handle pressure, i'd usually have a very light film of oil on the inside of some pipes after a few months.

but that doesnt explain oil in the charge pipes or am i missing something ?

VTC_CiViC

If the stock pcv system is still in use, there's likley a little oil being drawn into the intake/charge piping somewhere, you also have to account for some oil loss at the compressor/center section seal which I think you already pointed out.

pcv can explain oil in the intake mani but not the charge pipes.

oil in the charge pipes is either the turbo seals or the motor itself

i say just take off the turbo mani and see if the exhaust ports have oil in them. then youll know if its before or after
