Engine-followup

The story, in order: 1. "Taking the car up to BC." to confirm the diagnosis (wrist pin on #5 cylinder) Which involved renting a trailer. Late May 2005

2. "Opening up the engine." Wrist pin diagnosis was confirmed. Except it was all six wrist pins (#5 was just the loudest.) The beginnings of the head disaster unfolding. Early June 2005

3. "Uh, my aching head! Where the head was found to be under-spec just about everywhere. Mid June 2005

4. "Finished!" All buttoned up. Driving home. Late June 2005

5. This page.

As promised in the last update where on the last photo I said I'd document the stuff in the box of bits, here it is. It mostly consists of valves and tappets. I don't have the wrist pin bushes or valve shims, and while I DO have the valve springs and "improper washers" pictures can't really show you much about them. I also have the valve seats, but they bet pretty banged up when they get removed from the head - hard to see what is wrong with them at that point. So mostly here are the VISIBLE bits of improper construction, overzealous grinding, and wear.

Hard to believe Classic Jaguar has this wonderful reputation if their main engine rebuild tool seems to be an angle grinder. sigh.

Sorry for the oddly stretched thumbnails... I didn't use photoshop for cropping and iPhoto decided to do some odd scaling to the smaller files. The full size images are fine.

The exhaust valves.	Trying to show the ground valve stem tops.	Three of the six intake valves are shorter than the others.
	Trying to show the difference in thickness between the thickest and thinnest valve tops.	without flash
With Flash.	Here are the exhaust cam followers	A little closer.
Not only are they worn (quite obvious on some), they are also almost all ground down beyond minimum spec.	hard to light them all evenly in my office... trying different angles, backgound and flash settings.
Here are the intake cam followers. They were not as badly worn (only one showed significant wear)	but they were also ground down a bit beyond minimum thickness.	last shot of the intake followers
The hall of (wear) shame. The one on the bottom right is an intake cam follower, the rest are from the exhaust side.
