Awesome Sasha! Those pictures looks a lot like mine from last year. Hope you are well within spec so you can just hone and re-ring. You will be much happier with the compression and no oil leaks.

Ricardo, those coveralls look well broken in...

Well, two days of cleaniong and everything is ready to g for the block tear-down tomorrow. I spent hours with razer blade, WD40 and a scotch-brite trying to clean off the block and the cylinder tops. Then Randy showed me the easy way, a wire wheel on an angle grinder. The biggest problem with being w rookie at wrenching is not knowing how careul you have to be with what pieces. It went real fast once I took the wire wheel to it. Hopefully all is well. There is a groove in cylinder 6 that is quite noticeable when you run your finger over it. It is nice and smooth like the rest of the wall, but I can't believe it should be there. This engine might see the machine shop yet. Tomorrow should tell.

Pics of the wire wheel process.

OK, there is a pretty good groove in cylinder wall 6 from a broken ringthat has been doing its thing for a long time. Funny that the compression still measured well in that one. The block is now at Gunn's andI am expecting them to confirm that I will need to have it bored out to get rid of that groove. Seems like the thing to do now. They als said the lobes are worn and pitted on my camshaft, so does anybody have a recommendation for a good source for an RV cam? Otherwise everything looks OK...

Pics: 1) Tining marks must line up on the crank and cam gears, and that oil spurter screw is a pretty critical adjustment. Mine had two threads showing.

2)Those big slotted screws are quite shallow, staked with metal and are a PITA to ge out. Randy used a cold chisel and a hammer like a big screwdriver on the appropriate side of the slot to get them started.

3) There is the crankshaft revealed.

4) The block is ready to go to the shop now. Ricardo is about to lift it up with one hand and throw it in the back of my truck. This engine-rebuilding/strength building program is really paying off for him.

5) You have to eat a good breakfast before you spend a bunch of money!

The plan was to measure and inspect the rotating assembly parts and if everything was in spec; re-ring, replace bearings and put it all back together. When the scoring of the #6 cylinder wall was discovered, Sascha made the call to take it in to the machine shop. The machine shop will go through all the measurements and get back to him with what they find. We did check the oil pump gears and found the clearances to be tight and within spec. Throughout this project, Sascha has been taking pictures and care to bag and lable the nuts and bolts. I know this group is big on pictures and I did manage to get a couple related to technical content.

Here he is removing connecting rod nuts on cylinder 6.


Before removing each piston, the connecting rod bolts are capped with tubing. This is done to prevent any damage to the cylinder walls.


Each piston came out very smoothly. Immediately upon removal, the connecting rod cap was placed back on. The connecting rods were stamped with marks which make it easier to insure the orientation of cap to rod was consistent. The cylinder numbers were not stamped, so each was labled with the cylinder number it came out of.


Along with the block, the other components of the rotating assembly are ready to go to the machine shop.


Randy had pulled the Blue Mule into the shop to install twin shifters on the t-case. Here is Sascha's rig waiting for its new heart.
