Chuck Danke!
1) OVERFLOW tank NEVER FILLED by pressure from the hot side with my 20 lib cap on svivel tank.! I had OVERFLOW filled by 50% no change on all my driving, was tested (hence my worry that I might blow my engine head gaskets..no they are good no water in oil)
.2) will try 13 libs AND ALL CLAMPS NEW!!!
- i have a mix of clamps the old STOCK good once which I used at the
waterpump where the diamanter changes etc... all the nasty to work on parts
- dead was the clamp at the pipe at the bottem on the "forward pass" to radiator. Here I have all the crap clamps..guess >10 of them..all will go..
3) all water hoses are Silicon high end
4) cooling system is absolutely TOP CLASS, as we had 30 Cel/86F (Germyn ok! not AZ!!) outside when I tested it for a longer (save max 3000 rpm) ride. Temp stays on the scale max 110C/230 F when car is comming to stop in traffic/speed at IDLE (still need to validate the scale of the Italian "precision" instrument).
4) I measure at the BLOCK..
Danke!
Matthias..is a nice cat..brutal to drive ..what a fun car ..some set back I survive..
