I open this thread to inform the forum to what happened to me on 14th of february
Countrycruising already knows the story because we wrote some PM and mails in these days.
This is what happened:
14 february trip to Bologna from my town around 100 km 68 of these in highway
I very often check oil temp oil press and water temp expecially on these medium range trips. I was almost arrived and once again I checked the water and..... the indicator was stuck at 130°C .... it was terrible at 150 km/h on the overtake lane of the one of the most important and traficated highways....
I checked oil: temp and pressure were right. I immediately stopped the car in one emergency stop area on the highway and sadly I called for towing.
Steam was going out from under the expansion tank and I supposed that only 1 hose was broken...not bad.
Towing truck brought me to a garage near Bologna and when the car was down from the ramp I cant start engine, no also move from starter electric motor.
Guys of the garage removed all sparks and found water inside the chamber of the cylinder most near to thermostatic valve.
So, second towing to my usual garage.
Now the car is in Suzzara 15 km from my town in the Daniele Mariotti garage, specialized in works with Lancia Delta, various Ferrari and in general with sport cars.
He sent my 2 pics: in 1 is clearly visible an hole and in the other 1 detail of the head removed
Now some more pictures:
please note that:
- thermostatic valve was changed in 2013 (hose of death failure)
- the sleeve of the "hose of death" was also changed in 2013 (hose of death failure)
now I have the whole head the sleeve and the thermostat valve extremely corroded...why?
The coolant used was regular Paraflu and sometimes I topped it with demineralized water. Mariotti says that he had never seen such a corrosion and for him the problem is Paraflu that after years became corrosive on the alloys parts.
This is confirmed also by installes of my solar thermal system which use glycol as exchage liquid between the solar collector on the roof and my water tank in garage. I started to see similar signs of corrosions on some hose connectors. This system started service in january 2012.
The rest of engine is in very good conditions so I listened the advice of Mr. Mariotti and use from now after this expensive repair the liquid
We decided with sir. Mariotti to use in place of standard paraflu coolant a waterless coolant:
I also found this Edd China in Wheeler Dealer...Edd China Wheelers Dealers
The most important thing with Evans is to not mix it with any other liquid (water included)
Very interested in all your considerations. I'm very afraid to put again Paraflu in this engine.
