Folks -
A couple years ago, I bought a back-up A4 that had been mostly rebuilt from the journals up and is clean and shiny, with a bunch of old parts that were with the engine. The engine sat in my shop, unheated for about a year or so, covered with a plastic tarp, with plenty of airspace around it. I just took it out this week to start putting it all together again, and hopefully put it in my boat before she goes in the water in a month or two. The block is assembled and attached to the oil pan, but the head is still off.
All seems to be functioning properly, and everything turns when I put the crank on it, but the valve lifters don't want to spring back down properly and need a little persuasion. Ive been hosing them down with PB blaster every few hours for a couple of days and I'm making some headway, but most of them are still really sticky and one of them is still stuck.
Is there anything else I should be doing to un-gum them? Pour vinegar on 'em? Seafoam? Hit 'em with a big hammer?
Thanks for any thoughts,
Chris
