i just recently turbo charged my civic with a homemade kit and i had it on for about 3 days and i took it down the interstate and it was fine for about 5mins, then i got on it alittle bit harder, im running 7psi on a stock d16y8, it started shooting oil from the valve cover breather, i either thought it was the head gasket or the piston rings but im not sure does anyone know??

how much is "shooting" out, bc a little is normal

blackcivic

alot of oil came out, during when it was happening my car sounded like a wrx with a exhaust, there was no smoke or anything it looked like there was alittle bit of smoke in the dip stick hole

damn.. ive heard of this ---- happening.... in some cases it blows your dipstick right out

ya if its alot it sounds like blow by.

blackcivic

whats causing it if its blow by?

bad rings. It means that when your spark plug fires some of the pressure gets forced by a bad ring and into your crank case creating pressure that finds a way out. The only ways out are the dip stick and valve cover.

Open the oil cap and look for bubbles in the oil right after u turn it off.

could also try a compression test/ leak down test.
