hey guys I believe iv found the problem causing tons and tons of :banghead:
ok the drive shaft that sits on the back of the water pump connecting it to the timing chain looks as though the teeth are bad and been just riding along and scraping the water pump spline teeth, it fits snug and spins the water pump when i am holding the pump but when ever i press it aginst the block the WP fins spin freely (if that makes since), but timing gear is good it doesnt spin at all and splins look fine, does anyone have an extra drive shaft from converting to EWP or something?
