I have coolant in my oil and the engine sounds rough... what's wrong?

your motor is blown junk the truck or get a rebulit motor project done right will cost several thousand dollars good luck

You might get away with doing head gaskets, which is likely the problem but for what you would spend, pastaking is probably right. A crate engine if your transmission doesn't have too many miles, if it does then you're wasting your money and it will go next. Time to go shopping..sorry for that news and best of luck.

Depends on if you cracked the heads or just blew the head gaskets. If you cracked the heads you might as well get a new engine

At the very minimum it is likely you have a blown head gasket or a cracked cylinder head. As "FordNut" said, you might get lucky and just need to replace head gaskets. If this is a high mileage truck it may not be cost effective to repair it.

you may have sheered a tooth or two in your time & chain .or sretched it enough to jump time & get hot.possibly knock or overheat from lack of oil flow I would not jump to conclusions I would have a real pro look at it
