OK, I am going to be using a 2.2 engine I have that came out of a "Farm Truck" that I bought a while back and stripped it then took the carcass to the crusher. Some of you might remember the video I have of it running on the driveway.
I pulled it down today and it really is in good condition considering it had almost 200,000 miles. It had .006" end play on the crank and that's great for that mileage! The rod bearing that I pulled right before I got engrossed in "The Borne Identity" looks great as well, it has worn very evenly and the journal is prime as well.
This engine ran well (after I cleaned the carb out!) but had just a tad bit of smoke when you would rev it up, so I think I am going to just do a "rings & bearings" quickie re-build on it.......that is if I don't find anything too bad when I get all the pistons & crank out of it.
Here are some pics so far:
Cylinders look good for doing this.
This engine has never been apart either......still the way the factory put it together. I took some pics of different bolts and I am going to record their length so I know exactly what bolt goes where on a 2.2 Mazda motor!
Those 14mm head sized bolts come in about 6 or so different lengths so I'm going to make sure how the factory put these in.......one interesting one is a bracket on the pass. side that the alt. pivots on.....it has 4 bolts that attach it to the block, 3 of them are the same length and they screw into the cast iron block. The last one is about a 1/4" longer but it bolts into the side of the aluminum oil pump and therefore Mazda felt it needed more threads because the metal is softer I guess. Every one of these engine's I have worked on that were never rebuilt yet, have all had that longer bolt there. The ones that were rebuilt already, always get these 14mm headed bolts put all over the place......they couldn't remember which bolt went where.
I'm on a mission to document which bolt is supposed to go where!
Even the factory would get a little too much RTV squeezed out on the inside of the oil pan and baffle.
No RTV at the pick up tube to oil pump connection, just a paper gasket.
It is still stuck to the tube.
The bolts for the pick up tube to oil pump connection.
2 small bolts for the baffle to block connection.
The same small bolt for the brace on the pick up tube to baffle.
Down to the good stuff!
The #1 rod journal.
And it's rod cap bearing half.
Front and rear of crank.
Tomorrow the rest of the rods come out, and the crank as well.
