Hi......I'm considering a long-distance purchase of these motors. They are 25", and according to the mechanic......very clean. According to the owner, they have been lift-kept their whole life. (Yes I know. Take everything said with a grain of salt)
After doing research here in the archives I'm aware of issues that can be encountered with these motors. The more I read, the more I realize that even though they are Hondas, I could still potentially make a big mistake.
According to the computer, they have 830 hours. The codes are saying one O2 sensor is bad. No overheat events or low oil pressure.
One spark plug won't come out. I'm still waiting for the compression results from the others.
As I understand it, here are the problems that can develop with these motors:
-thrust bearing failure
-tensioner failure, causing timing belt failure, causing damaged valves
-block corrosion, causing pin-hole leaks (in the water jacket?)
-oil pan corrosion
-exhaust tube corrosion (is this like what's happening with Yamahas?)
Am I missing anything else?
OK, I'm pretty handy, and if I get over my head, I've got a good friend who is a very good OB mechanic. On the face of it, the only issue that scares me is the frozen spark plug. How is that dealt with?
I'm using a Honda mechanic long-distance to survey these motors. But he said something that makes me wonder if he's any good. He said, "The spark plug won't come out probably because of carbon buildup on the threads inside. Run some Ring Free through and it should finally come out."
Does anyone here buy that?
I could sure use some feedback before I make the decision. Thanks.....
