Yep, I have had to clean out a GM 425 large block for my '66 Dynamic 88 convertible land yacht. Oil and water does mix... :bad:
The glass is not half full, it was engineered with a 2X safety factor.

Working on it Steve.  Sorry Pat, Lilly will not be at the rally.
As for the substance, it's what it looks like when water and oil is mixed together and pumped all through an engine.


Now, after all this time, it's time for the "Holy Mill" to be opened up. (Or more accurately, I need a good cylinder head, and it's the best one I have available) Pulling it off was easy, but holy crap was there a LOT of carbon build up on the combustion chambers.

Wasn't really worried about that because at the moment I needed to replace the valve stem seals.



Of course there's all of the plastic welding required to get the fairing jiggered back together. (Poor bugger, he's scarred now)

Can't seem to get the your tube videos to display right.

But yes. Some rain water got in the case a few days before I brought it inside.

Hey, does anyone know what the thread size is on the bolt that anchors the rear bottom most corner of the fairing to the frame? (I've got the tab that it's welded to repaired, now I need to put a new nut on it)

Mike, I tried to call but no luck. Do you mean where the side scoop connects as well?

Most of the fasteners that attach the plastic is M6 x 1.0.

If it tossed a rod -- make double sure the valves from that cylinder aren't bent.  When the rod goes, the crank tends to knock whats left of the rod/piston combo back up the cylinder and into the still functioning valves (at least for a revolution or two until everything has time to stop).  Don't want to have to go back in again -- DAMHIK!

What's with the extra valve shim that appears to be laying in the slurry, next to the #3 exhaust valves?

Draw a line from that extra shim to the #4 spark plug and you'll see the rusted screwdriver bit hiding in the fins.  Reminds me of the old Highlights magazine at the Dentist office where you'd find the hidden objects in the picture.

I don't think that it's extra...I see the edge of the bucket, so it looks like it just fell out.

The rusty screwdriver tip is a good spot....I've lost a few things in those fins before.

Mike has his hands full for sure. Anyone want to start a pool?

Confirmed the Monkey Man's assumption of which screw and which pitch.  This is on my '92:

OK, I see it now. It popped out of the bucket that it is next to.

Whenever I have a look down in the top of my cylinder head, I find all kinds of winged creatures baked to a crisp. Usually the stinging kind.  :pardon:

Freaking awesome guys! Thank you so much.  It's amazing how you get overwhelmed and little stuff like that escapes you. (I was heating and beating the snot out of the old mangled tab, got it mostly back into shape using a piece of 1"x1/4"x2" bar stock behind it as an anvil.)  It's shape is basically restored, but I need to weld where the metal is torn and tack weld a nut to the back side of it.

I have a list of what still needs to get done:

Clean Combustion Chambers
Replace Valve Seal
Put the tail section back on
Reinstall Install Cylinder head
Reinstall Cams
Mic Cams
Swap Ignition rotor over
Fix Frame Bolt (M6x1 Nut)
Reinstall Engine
Check Cam Timing
Tighten Oil level sender nuts
Transfer Oil temp sender
Torque galley plugs
Reinstall oil cooler
Put new ground lug on
Reinstall oil filter
PUT OIL IN!
Reinstall carbs
Reinstall exhaust
Put in Battery Box
Fix Tail Light
Rewire tail section
Reinstall fuel tank
Reinstall seat
Reinstall side panels
Put Brake and Shifter back on
Reinstall chain and rivet link
Install Headlight in Fairing
Fix Fairing power panel
Put Fairing Frame together
Replace throttle cables
Install Grips
Install fairing
Install and fix wind screen

Am I missing anything?
I definitely have my work but out for me. (Especially since I have the weekend tied but and I only have tonight and tomorrow night to work on it)

As for the tail section, the bike almost looks better without one. (Well from a frame stand point.)


Though, since I have the tail section off, I couldn't resist putting the hugger I just acquired in place to see how it looks. (I think it looks pretty good) The real test is going to see how it does with the full range of motion from the swingarm.

The tail section is twisted pretty badly. I know I have a picture from the rear of the bike somewhere, but it was REALLY making it look like I had SERIOUS alignment issues.


Switching gears, I did get the shift detent arm installed. Without having to remove the clutch basket. Though this is only really possible with the oil pan off.


So I guess in that sense it's really cheating.



Rub a dub dub dub, one FJ engine in the tub... This thing is thoroughly cleaned up. Now I just have to rinse it out and get the rest of the stuff back on it.



Yeah, there's always something lodged into the fins. (Though that screwdriver bit became quite handy in getting some of the stuck fasteners loose)
And the valves look fine. That piston was well down in the bore. (Skirt just below the level of the sleeve)

Funny, ever since I installed my HID head lamp, I don't see them on top of the engine anymore... The small fireworks show at night can be a little annoying....

Mike, how much time did you spend typing and posting up the pics? Your time is too valuable right now, post up later.... Sleep when you get Coleville... Consider this a spank from the Monkey...

Mark is right Mike... You can untwist the tail section after you bolt the front 2 bolts back on.  A nice 6 pipe or 2X4 will tweak it easy. They are flimsy.

Yep, I would add to your list... Re torque rod bolts.

Just a suggestion.
