Wow, what a great discussion!

<blockquote id="quote">quote:<hr height="1" noshade id="quote">SeaFoam is an oil additive available at Walmart and similar stores and every auto parts store anywhere I have been. A very old company and product that will dissolve carbon deposits from rings and oil passages, ect.<hr height="1" noshade id="quote"></blockquote id="quote">

Here's my question: I have an older motor running good, no leaks, etc. How much of that is due to the integrity of the motor and how much may have been self correcting (carbon buidup in the right place at the right time)? By using something like a SeaFoam product, am I at risk of messing up a good thing by cleaning it up? Or, do the benefits of cleaning outweigh the risks?

The Fisher's Island Ferry never comes bearing down at you from the end of the driveway when you can't get the mower started, does it?...

No, it doesn't, but if I were out on the water, I would certainly be aware of both the ferry route and schedule so I wouldn't have to resort to frantically starting my outboard to avoid a collision.

If you want to clean the crankcase with less risk add less, say half as much as normal and start changing the oil very frequently, as soon as it starts to darken. Normally there will be deposits coating all the metal surfaces inside the engine and carbon bits in the rings, and no risk at all. If there are deposits that are so thick or globs of muck that will accumulate in the pan or the top of the cylinder head than there is no risk either it is a certianty that peices will break free as they dissolve and plug the oil pickup. Knowing what you have is not simple. It is very unlikely that it will be a problem unless someone put non detergent oil and did not change it for three years. If you know that there has not been black oil in the engine for many years than there is little risk.
