I just changed the oil (its at the full line on the dip stick), and changed the plugs (used the .035 champions), also had a new muffler (flowmaster 40) installed and now the engine will blow white smoke from the back after about 5 mins at idle. Any idea what could be wrong?

 

back of the engine or tailpipe?

 

back of the engine, there was some coming out the tailpipe at first but now its just the engine

 

maybe too much motor oil???
that usually happens when i put too much trans fluid in

 

Sounds like a bad head gasket, check your oil to see if it's milky. How does it run?

 

Yeah I was fearing a head gasket. The oil was looking clean, I check it first but maybe it would take a while for the water to mix in since this just started?

 

sounds like a headgasket. i recently saw mine smoking white to. but mine is comming from closer to the top of engine. maybe we have same ordeal.
