Yes, newer cars are Expensive to Fix...
Decades ago, when my "BumbleBeast" had its first Head Gasket problem, it was "Blowing" outside the engine the coolant, only at Operating Temperatures (warm), from a point under the engine, where the head meets the block, nearby the Exhaust port... the only way I could find that, was to crawl under the Subie to inspect the engine when it was off and cool; then I found a very "Clean" area right there: the Hot coolant coming out, came as Vapor which cleaned said Area, and that is the Reason why it was very Hard to find the leakage.
Maybe it is the same case happening with Ned?
Agreed! I started with a $600 bill, now its over $1300 and Im not increasing any power, just helping keep it cool.
That could be... At my work, my mechanics have a constant supply of brake-kleen so were gonna grab some empty cans, refill them and just brake-kleen the entire motor so I can see the leaks... I have so much mud that its impossible to tell where the leak is pinpointed because all I have is dry mud and then wet mud in areas... but the wet areas could have leaks from anywhere, and just be spreading.
