Help!!
I noticed a little smoke coming out from the back of the engine block, took the car to a mechanic and he told me I need to replace the (ring) gasket seals & that I could still drive it as long as I kept the oil level where it should be.
The problem is that when I check the oil level after the car sat overnight, the dipstick shows that the oil level is normal. Once I start the car however, the dipstick comes out with barely any oil in it, as if the engine doesn't have any.
It is important to note that the engine is a little noisy and lately it feels like it's struggling to pick up speed after first gear & it's consuming gasoline faster than when I had just bought the car, i don't know if that's all part of the same problem but it's driving me crazy!!

I'll provide pictures if needed for a clearer understanding.

 

You probably have sludge buildup. You may want to take care of the asap.
