I brought 2 of my 1.6TD heads to a trusted FLAPS to have them checked out.
One of the heads had small cracks on three of the steel preheat chambers but
had a flat sorface and no cracks between valves. The machinist called me back
and said the head was no good because of the cracked preheat chambers and
would leak coolant. I was dubious but brought him another head to check out.
He called again this morning saying this head had a cracked valve seat and
was also no good. Coincidently they have a rebuilt head in stock they would
like to sell me.
Am I justified in being suspicious?
