I recommend doing it yourself if you want it done right. +1 on the YouTube videos. Really not that bad of a job if you're inclined

Did you get your truck fixed? If so, what was wrong with it?

Did you check the intake gaskets?

Haven't tried yet what's the mkst efficient way to test and could it be cause of the double platinum plugs that are gapped at 0.60 or the coil?

I run the stock AC Delco plugs on my 04 6.0 Esky there platinum forget the number could look it up if needed GM changed the spark plug gap from.060 to .040 back in 08 or so there's a TSB, you could have a bad coil pack my Silverado had one but it was nothing like the bad intake gaskets I had on this truck my symptoms weren't even close

I'm having all the symptoms of intake gaskets on my 01 5.3 but I'm also losing water but can't seem to figure out where. Anybody else had coolant loss along with the other symptoms?

Head gasket? The exhaust blow white or smell like coolant?
