Hi,

That sounds like a lot of different issues. What color is the exhaust smoke?

Take a look through these links and see if they help. Also, let me know about the smoke and if the exhaust could have a converter plugging.

Let me know.

Hello,

This sounds like you have at the very least a blown head gasket, possibly other internal damage like worn bearings or a damaged crankshaft. Here are a couple of links below to test if you have a blown head gasket:

Please go through these guides and report back with what you find out.

Thanks,
