I totally agree. Just for kicks I went to look on e-bay at engines.:
1) a guy was selling a new upper manifold air plenum that he didn't get to use since he developed a rod knock before he got it.
2) someone was selling an engine for parts - same story, he replaced the plenum and a couple months later got a rod knock.
I thought I caught my coolant leak early. No signs of coolant in the oil and I c/o the oil twice after the plenum replacement.
