I have a really bad oil leak on my 1993 subaru impreza and blue smoke coming from the exhaust

head gasket is blown

have the cv boots split check these if not check for cracks in box could be a faulty oil seal where shaft goes into gearbox

Hi this sounds weird does the smoke come out from the front engine covers? the squealing could be the cambelt trying to turn a semi or completly ceased waterpump which would cause the smoke after a while, also without the waterpump working properly the engine will leak water and anti freeze out the overflow and overheat really quickly

i would thank bad turbo. turbo leaking oil in to motor

White smoke is usually coolant, oil is usually a blue color, most turbos r cooled by coolant so U may have a coolant leak in the turbo, may B a seal or crack in the turbo. Check your coolant level occasionally to C if it drops.

check your turbo
turbos tent to leak from the seals also its always good to buy an oil catch can

probably leaking rocker cover gasket ,oil slowly lands on exhaust,ive got one and had exactly the same symptoms and rocker cover gaskets were the issue

Hi, you may have a valve cover gasket leak that is dripping on the exhaust manifold. I would inspect the valve cover area for oil spots and rim leaks. The smoke is coming from the dripping of the oil on the manifold or, lower exhaust pipe.

Please rate and god bless:)

this could be down to one of the seals in the turbo leaking and letting oil through
