could leaking intake manifold gasket cause white smoke from tailpipe ?

oil clean , pressure test cooling system shows internal leak looking at truck for a buddy evidence of slight intake leak at lf area ( common ) more diagnostics i guess, been a long time since i seen bad head gaskets on these engines. thx pushrod !

A combustion leak test will help confirm head gasket issue!!... Can air test misfiring cylinder on (compression stroke) also.... to be sure!!

just goin on what the guy has told me havnt heard it run yet, he has to buy a battery (omg, people ) ya ill pull the plugs look for a white one or two afetr i hear it run and do compression test thx man !
