Well just got back in town and decided to drive my winter ride one last time before moth-balling it for the good weather months. Jumped in and started it up and saw what I thought was the usual first fire-up puff from the worn valve-guides, but it didn't go away and turned very white in color and tons of smoke. Still runs good off idle but stumbles terribly at an idle. No external leaks of antifreeze (had that before and replaced the lower intake gaskets). Pulled the plugs this morning (lots of fun) and compression is equal and pretty decent for 221K motor. There is no antifreeze in the oil at all.
Can the lower intakes blow to an intake port and cause this? Number 5 plug was steam cleaned and after filling the radiator
and pressurizing the system with the plugs out there is definately antifreeze POURING into the #5 cylinder. If it is just the intake gasket I will probably go ahead and fix if not I think its will be time to lay her to rest at the big scrapper in the sky LOL.
