YOU have a CRACKED INTAKE MANIFOLD!

Face this! Every intake manifold used in EVERY motor in a GMC Motorhome has (most probably) a crack between the secondary ports. This is an absolute statement of fact ….. and IF your intake manifold is not cracked …. brother it will soon! I’ve done many videos on this STILL I find folks that are surprised when it happens to their coach. Yes, I’ve been on this soap box so long I’ve got nosebleeds……guys, get off your butt and make sure your coach has this modification! It took decades for me his issue to come up but budro….. it is here. Once more hear about this and take this to heart. I still find folks hearing about this for the first time…. Good thingYOU are not in that “flat earth society” camp. Spread this word…..
