Re: Yanmar 2QM15: How can I keep it running forever?
Rusty, I've got the 2qm20, 35yrs old.
i just took the exhaust manifold down to my local machine shop. They tanked it, cleaned it up and it was fine. A few over priced gaskets and 30mins later I was back in business.
There was no unusual corrosion in the manifold, but it was pretty clogged up with carbon.
I didn't realize that the exhaust manifold an elbow were unavailable. That sucks. We may have to settle for having them last *our* lifetime instead of forever :-)
