Today was good. I buttoned up the 850, and decided to start on the 122's new B20. The history of this engine is not very clear, it came with my old ES. That guy was somewhat vague, and given time, what I remember may have nothing to do with reality! What I recall, is that the guy had a '71 142 with a nice engine, with IPD BIg Bore kit, Street Torque cam and some other mods. He wrecked it, and bought the ES with the intention of putting this engine in the ES, but all he ever did was disassemble the ES, get a girlfriend, and that was that.I ASSumed that the 142 was a E, not an S, but I think I was wrong, as one of the engines I got ( the 'hot' one) was fuel injected, and had the oil temp bung, and the other was a carburetetd B20 in unknown condition. After looking at this one and verifying the nimbers, I think I have the ES's block, and the guy swapped the 142's head and oil pan.
Anyway, I started by getting the engine on a stand, and then pulled the oil pan. Looked nice and clean except for the three big crickets in the oil pan...I'm not sure how they got there, but I doubt they were happy. They were well preserved however. Cleaning those out, I also realized that the pan gasket was a used and well siliconed item, and tossed that in favor of a new one. I popped the timing cover off, and stuck in a new felt seal, and them moved to the rear seal. Wow I'm glad I did that! There was no rear seal, only the retainer! I had a nice looking used one and stuck that in.
With that, and piecing together what I think the history of the engine is, I decided that the head gasket might not have been new when installed. So I called my buddy Brooks, and he's got an extra one, since I doubt our sorry parts houses have one in stock and could get one by New Years Eve. So I popped the head off, and sure enough, the gasket was used. But I'm not sure about the rest of the engine now. Supposedly the ES had only 65K on it, but the #1 bore is scored, and something got in the #4 cyilinder and put a nice ding in the wall. There's some taper in all cylinders that I can feel with my fingers, but no ridge ( how can that bet?) So who knows how this engine will run. It can't be any worse that the old B18 with it's nice round cam and whopping 115 PSI compression. If nothing else, I have a full 2 liters of worn out engine!
So I expect Monday the engine swap will begin. Dave Matz wants to come over and help and observe, so I expect he'll hear my cussing at it's finest. It always helps with those rusty bolts ya know.
