Ok, engine is just about down to bare block. I am conteplating on how far this rebuild will go.
Do I take the injector cam out as well as the lifter out then replace the bearings?
Do I take the block in and steam clean it? The PO had too much water in so when I drained the radiator this morning, DARK brown. Do I replace the t stat?
Will standard rings/piston be enough?
Now for the iffy stuff I found out regarding #2 problem child piston.
The piston and rings somehow ended up off center in the cylinder thus creating a minor lip for about 80% around the wall. Now I would assume that I can take a ridge reamer and take that off. I checked the construction of the piston itself and the first 10 mm or so consist of 3 sections divided by a groove. So basically where the ridge begins, the piston compression would not be affected (as far as I can tell) The piston itself has minor wear as well as slight scuffing on one side. I have seen a lot worse, so as of now it will remain and get new rings.
All the valves were caked with carbon buildup. They looked good, but will need a good cleaning, grinding the angles and re seating.
The head looks great. No visible sign of any stress in one area. Valve guides looked good and tight. I will need to clean the water passages to get rid of some minor buildup.
and finally, the crank looks great as well. I wish they you use bearings for the journal surfaces on all small engines. Makes for a cleaner and easier rebuild, in my opinion.
Well, Here is a 10 min video of the block and all the parts laied out. I ramble on and on, but I showed some goodies along with the lip (if visible) and head. Camera, I mean the phone would focus in and out, sorry.
Hmm, well the video is not uploading, sorry. I will post it up tomorrow.
