Running Hot, UPDATED: Solved!

Did you ever happen to use a wire wheel to remove old head gasket material? I've heard of that causing micro defects in the deck and head surfaces that can cause an issue like what you appear to have.
If you do tear it down that far, check the heads and deck for trueness, perhaps your previous machinist was a bit lazy on the details.
Sucks you haven't licked this thing yet

I've been tempted to stroke it, but I doubt I'll do that. I'm thinking maybe going .010 over. I'll check wit the guy at the machine shop to see what he says. This time around, I won't be as rushed to get the engine built as I was when I did it the last time. I'm going to take care of that damned plenum one and for all by having the bottom plate welded to it for a nice, fool proof seal.

OK, so it's going to be a while before I get around to tearing the engine down since I can live with a tiny, tiny, TINY head gasket leak. This past weekend, with outside temps in excess of 100º, my son and I drove 200+ miles, round trip, to pick up some VW parts from a retired VW mechanic. All went well with the truck staying around 198º. Yesterday, when I headed to work, the temp gauge wouldn't budge above 150º. While stopped at an intersection, I turned on the heat (FULL) and placed my hand in front of a vent. The air was was warm, but not impressive. So it looks like the Failsafe thermostat has decided to stick partway open or has failed.

I did within the first few thousand miles after the rebuild. After 4+ years, would it really make a difference?

Thermostats are supposed to fail in the open position. It pisses me off that the damned thing costs too much and lasted about as long as a bag of heroin in Amy Winehouse's possession.

I use to be a hardcore supporter of failsafe's, but when I began to have overheating issue's, I bought an OE stealership stat and compared them. The OE stats open and closing tolerances were much tighter then the failsafe's. I run an OE stat now.
