Gang, It Looks Like We Have a Mystery to Solve

Oh My Cruella! What mystery?

Well, this is a rather long and involved explanation (read: boring, I don't insult anyone or talk of anyone's bad behaviour). But what happened was Dad complained that his car was making a "humming" noise he could not figure out, and made a quip about it being unlikely not to know the words.

So I finally stop working long enough to look at the car, and after touching various places in the engine to see where it is coming from, it appears to be the PCV valve. I suggest replacing the PCV valve. We do this.

The "humming" noise does not stop, and I discover the PCV boot is loose. I suggest replacing this.

We go to - several- auto parts stores. The people at Autozone enthusiastically recognise me . . . I was there earlier with Black Rook and got into an undoubtedly noisy and entertaining debate about who was going to pay for the tool I needed to work on Black Rook's car. For the record, I would have considered splitting the purchase, but two of my cars are too elderly to require this special tool. GM apparently has a special whole division dedicated to coming up with stupid new shapes for screw drives. Torx wasn't complicated or stupid enough. I bet every single fastener on a newer GM car requires a completely different kind of driver. There's probably a kind that has a hole/slot in the shape of a small religious figurine. At any rate, since it was for HIS car that the special tool was required, and it would ONLY work for his car, I felt HE should pay for it, and loudly voiced this opinion.

Yet I digress from the Mystery. So Dad has time while I am driving to inspect the PCV boot- and discovers it isn't a PCV boot at all, but is stamped Dist-Coil. So it's a boot off of a coil wire instead.

We hunt for a replacement boot at several auto parts stores, and for some reason they only seem to have boots for Ford and Chrysler products. There are a few GM boots but none of them appear to fit. I get irritated and decide to solve the problem with a bit of exhaust manifold hose.

This works. But the mystery is, how did the PCV boot get replaced with a coil wire boot? I know I did not do it. Dad did not do it. The only other person to have fooled with the car ever is Rick, and the last thing he replaced was the water pump last spring-ish. Had he in fact replaced the PCV boot with a coil wire boot, it would have started making the noise a long time ago, as the noise resulted from the boot collapsing around the PCV valve . . . So we have a mystery as to who did it and when and why didn't it start doing it before now? It only started doing this after the snow!

I am hoping for a full on Scooby doo mystery.
