so today i i checked the the cooling system and found out that my radiator went to war and came back full of holes, so i replaced it filled the car with water and tried the started went for a drive and the engine didn t overheat in fact it worked much better then yesterday.

The thing is that it kept on knocking and couldn't hold gears had to constantly downshift which is annoying, also on idle it vibrates alot and somehow the ammont of oil i have in the engine increased after half the engine got covered in oil.....

i'm guessing this could be an effect of water leaking through the head and mixing with oil ?
