"Hi Andrea & Enrico,
Thanks for the prompt reply to my query: "At any point of the Merak SS production run did Maserati
start using solid exhaust valves?" Just for the record I live in Atlanta, Georgia. Prior to buying my Merak SS, I read the "Please Help"- Merak section of your web site very carefully....it was very helpful. You do a great service for the Maseratisti.
In my recent visits to the site, it appears that no new posts have been added in that section. This is in no way a complaint, just an observation. We are all busy, so what you have put out on the net is great. I would just like to see more on the Merak SS. Maybe, I am just not looking in the right section of your web site. Forums are great, but a lot of times it's a hit or miss proposition.
My 1980 SS has had an ongoing driving history with about 22,000 miles on it. I took your advise about buying one in really good shape, and not one that has just been sitting around either. All the vitals oil pressure etc., look good, 3,000 rpm is my shift point, and 4,000 rpm is about as high as I go. So I don't anticipate exhaust valve problems for the time being. I just enjoy driving it. Later on I will look into replacing the exhaust valves.
The reason I asked about the valves was that on one of the forums there was a long discussion about the exhaust valves of the C 114 engine. As the discussion went the original valves were EL BM FS for - Eaton Livia Bi
Metallic Filled Sodium. The SS C 114 Engines were labelled EL ST BM FS [ST
for the STellite hardening process to reduce wear]. Finally, it was said that
the factory shipped solid valves marked EL BM. However, some of the exhaust
valves it was said were solid and others were marked as solid but were not. The discussion ended saying that a magnet should be used to truly know what kind of exhaust valve is in that engine.
Just thought you might want to know.
