do a leak down test, compression test, and get this chemical shit they sell at auto stores, i forget what it's called but you add it to the radiator, it will turn a certain color if oil is found in the coolant.

it could be anything really...
headgasket.
rings.
pcv valve.
timing could be a little off.

Sounds like Symptoms of a Generic chipped ecu. Those generic chips are all programmed to run rich @ higher rpms to prevent the motor from leaning out. Nothing beats a stock ecu on a stock motor. Keep it stock, unless you plan on getting some A/F correction.

can i just take it the chip off or do i have to modify something??

dont cheap out on a chip, get it tuned by someone right or get a setup you can tune urself liek zdyne or hondata.

ok, do a leak down test

if you hear air coming through the valve cover, you have bad rings/valve seals
if you hear air out the intake, bad intake valves
air out the exhaust, exhaust valves
bubbling coolant, headgasket
