Is anyone else rebuilding an engine or anything?
I know lee is working on a car engine of sorts.
I had amazing tunnel vision the other night after school. I brought the engine for my Honda up into the living room and started the disassembly process. Most of the screws are stripped, so I set all my focus on the removal and disassembly of the head.
It took me like 30 minutes to disassemble the head without taking apart any of the side case.
We're talking the whole jug.
I also found out what siezed and why. The pin that connects the piston to the connecting rod seized. This is good, because my engine is small and low revving. It caused almost no real damage to my cylinder. It was burned as **** though, the whole thing is BLACK. The rings disintegrated while I was pulling the cylinder off.
What I found was that someone had rebuild this engine. Rather than sanding all the mating surfaces smooth for a flush fit, they shimmed it... with liquid neoprene gasket junk.. This is probably what was causing my oil leak. They also blocked the oil port to the head. And it looks like they instead opted to pour a little oil down into the head every once and again.
The rocker arms look new, the valves look new. So I'm thinking a top end rebuild was probably the last work that was done on this particular engine. I haven't been able to split my case because like all of my screws are stripped out. I need an array of drill bits.
If anyone ever needs to get a stripped screw out of something this is how I do it. I find a drill thats about .005-.025 smaller than the threads (just guess if you don't know. Think about the same size) You drill down through the center of the screw untill the cutting edge of the drill bit is just about to seperate the head of the screw from the threads. Jam a pin punch in there, pry hard. Screw head pops off. You can drill all the way down until the screw head comes off, but you don't want to do this. You want to preserve the hole and the threads. If you **** up the threads in the hole, you might be able to tap it. You might be ****ed. You're probably going to be ****ed. This is a bad kind of ****ed to be when it's holding together something like your crank case.
When you pop off all the screws you need, remove whatever they were holding down. Then you take some vise grips and spin the rest of the screw out.
It works better than it sounds, but it takes practice. It's essentially the same operation as drilling out a rivet. Which I'm also pretty good at doing because I've drilled out a lot of screws.
I'll post some pictures later of my engine in it's current state of disassembly and what I'm doing with it.
