Smoky exhaust
Hello. I have blue smoke from my exhaust. I know its caused by excess oil being burnt. I have an small oil leak from the manifold to downpipe connection and where the exhaust clamp meets, small amounts of oil can be found around it. Any suggestions.?.

Re: Smoky exhaust
Is it just when you start the car, or continually smoking?

Re: Smoky exhaust
A smoky exhaust is usually a sign of cylinder bore or piston ring wear. Compression test would be useful. If you get a low reading which increases after putting a teaspoon of oil down the plug hole and re-testing suspect worn rings. If not, maybe valves sticking or leaking. Presumably the car is using a lot of oil?
