Scotty shows some things you should never do when fixing your car IF you want your car and your own body to survive unscathed.
Have the cat pressure tested, the old blown gasket may have clogged it up
Now my car doesn’t start up after throwing up p0420 code
Plus it smells when I turn on the fan in the cabin. Never had this issue before.
Hey Scotty, I’m the 03 civic with new head gasket. So the smoke is gone now but my car starts to over heat very fast when I drive it for like 5 mins. It doesn’t over heat while idling even for long time. Plus it doesn’t blow heat in the cabin. What’s the issue now? Thanks
