It started about a week ago. It sporadically blew blue smoke, small amounts when going at slow speeds, stopped for a few days, then started a couple days ago again; last night it's doing it while idling. Again, very small amounts. No engine lights. Either piston rings, valve stem guides, or PCV valve? What else could it be? I'd like an estimate before I take it in :(

Brake check engine and Eml light is coming on

It into the diagnostic machine and it is coming up that the brake fluid level is low but I opened the bonnet and looked in the brake fluid is full.What could it be

It only does this at random times

After shutting off the engine taking a drive from office to home 15-20 miles, Coolant starts leaking continuously at 2 spots down the bumper. Got diagnosed for two times from two different persons wasting time and money. Performed thermostat test and done pressure test on reservoir, radiator as well the hoses & got result of good holding pressure in all three components. couldn't diagnose the exact reason for leak and still worrying of the coolant level running out from the reservoir and got frustrated refilling it. Some says its water pump problem. I have video of it. But couldn't find the option to upload it. Can anyone tell what might be the possible causes of coolant leak after the engine is shut off?

got a multi cylinder misfire

What signs would indicate that my water pump is malfunctioning?
