Yea a friend of mine had some engine cleaner/armoral. It makes all of the plastics an covers an everything look nice an shiny like he armoraled his engine. All he did was prayed this stuff all over his engine an just let it sit for a few min. an then started his truck up. Where could I get something like that an what is it called? Thanks

I used to clean my Lumina ngine with Simple Green and a hose, but can you do that with a 5.3L? Is there anything you shouldn't shoot with a hose?

Only thing you have to worry about at all on the 5.3 is there is a design flaw with the rear bank knocks sensor. Water can leak in and damage the sensor and cause corrosion on it. It will turn out like this:


Just try to avoid spraying the very back end of the engine, like dont get it all up in the intake manifold. The fix for this is just to seal the sensor off with som RTV, I recomend doing it if you wheel it alot.

On my truck i cover the TBI, the distributor and the alternator with tinfoil. Then hose it down liberally with gunk foamy engine cleaner. let it sit for about 5-10 minutes and spray it down with the hose.
