Oh it’s not (I don’t believe). Mine was in for oil leaks and other such things. One leak was my failed replacement of the intake manifold where I didn’t put silicone on the seal where the cam lobes are, other various aged seals etc.
it got new sump gaskets, new bearings, new oil pump, new gasket for the intake manifold (with sealant this time), new diesel return line as one was leaking (surprised my car didn’t go up in flames give the problem), and various other issues. Also fitted the new AC valve. I assume as it was body off they removed the engine, but I never asked and never saw.
All told it wasn’t cheap, but all told, I think an investment given where I want to be in it. I’m hoping it’ll see me through the next five years minimum.
