Thinking out loud about valve guides
« on: September 21, 2015, 18:21:53 »
If my 1967 230 has had about 20 miles driven in 6 years wouldn't it make sense that the valve stems would be brittle/broken but the guides would be fine? I called the mechanic to get a quote to have valve stems seals replaced. He said I was wasting my time unless I checked the valve guides too (much more expensive). What do y'all think?

The valve guides can be checked during the relatively simple valve seal replacement. At such low useage you might as well just fit the new seals, they'll work for a few hundred miles even if the guides are worn.

I assume you mean the valve stem seals, right?  Is there some symptom that makes you think they are leaking?  Unless you are tearing down the head anyway, I wouldn't mess with them unless you are having a problem.

Seems like an efficient use of time and resources.  ;)
