Two problems 1 spark plug has blown out twice from cyl #3 and 2 brakes are grabing and making the truck shake bad. Any suggestions on how to fix the spark plug problem or any after market heads to replace the stock ones. I have heard that there is not enough tread on the heads so the plug comes lose.

 

Yes, you need to install an insert (timesert or a helicoil) in that hole. They are relatively cheap (compared to a new head), and they can be installed without removal of the heads.

Do a search, you'll find all the info you need.

 

Thanks I'll look into this, its making me so mad that i want to get rid of this thing
