white smoke
truck is running great, one issue is whitish smoke from exhaust, heads were redone about 6 years ago and sitting in bags to protect, assembled all looked good. leaning towrds running a compression test and leak down test. maybe replacing or installing the umbrella seals on intakes and exhaust valves

White smoke = water in the cylinders , but if there is antifreeze in the system you should detect a sweet smell. May just need new head gaskets , better than a cracked head or block, good luck.

What transmission do you have? If it's an auto is it shifting properly? White smoke can come from ATF being sucked into the intake due to a bad vacuum modulator on the trans. You'll know for sure if the truck stops moving after enough ATF gets consumed.

just got done pulling vaccumn line at transmission modulator, bone dry, so maybe unbolt master ans pull out to see if back seal is leaking, then go do a leak down test. need to buy a cylinder leak down tester, anyone have input on whos to use and whos to stay away from as far as manufactures of leak down testers?
Thanks
Thanks
