Sprite interrupted

I think I found one of the contributing factors for our engine failure. The oil filter remote was sealed with a bunch of silicone against the block. Not that that's generally a bad thing, but you don't need to use half a tube. The main artery to the oil filter was nearly completely blocked with a sphincter of clear silicone. Some oil could still get through, but really not enough to effectively lubricate an engine running at freeway speed. The oil pan was filled with bronze shavings and an unidentifiable hunk of metal about an inch long. I also found what appears to be a worn out rod end bearing inside the oil filter can. I have no idea how something like that could have gotten in there. None of the oil channels are big enough to allow something like that through. The rod bearings for pistons 1 and 4 are completely shot. The rods clunk back and forth easily. Curiously, cylinders 2 and 3 are the ones with bad compression. I also noticed that the engine had been painted while assembled. There was conspicuous overspray on surfaces that aren't easily visible when the engine is in the car. It looks like whoever did the restoration ran out of enthusiasm after completing the body work and had decided to sell the car before he got around to the engine and transmission rebuild and just painted the engine to make it look pretty. There's also plenty of Stop-Leak in the water jacket.

Oooo, sparkly!


Not much oil can get through there.


More broken things. Color me surprised.


On your left, from the deepest, darkest corners of an oil filter can, the metal with mettle... A Semi Cylindrical Chunk of Bronze!

And on the right, brimming with random destructive potential, the oilpan annihilator... A Bent Hunk of Steel!


Shockingly clean for how bad most of the individual parts are.

"Rebuild in a can" makes another unwelcome appearance.

I know of a currently unused engine of similar size that would probably fit in Oliver... It's a bit more sporting in nature and has a superfluous 100hp. Perhaps just keep the original redline?

Hmm....I doubt this is your next LeMons car (or is it? That would be interesting), so I hope this Sprite digression is temporary.

Sorry, I'm not a very linear person. I paint what I see, if you know what I mean.
