Well, if the engine is already a write-off, why not just sucks some vinegar into it, let it sit over night and then run it the next day to see what happens.
I think you'll be surprised. My next boat will definitely have a fresh water cooled diesel. ~Dan --- On Wed, 7/28/10, rmacura <[email protected]> wrote: From: rmacura <[email protected]> Subject: [IC27A] Re: Universal 5411 Acid Flush To: [email protected] Date: Wednesday, July 28, 2010, 3:44 PM Thank you Dan and Tom for sharing. My reasoning is that it might be too late for me. That is an acid flush of the whole engine will work the best if the cooling space is still open ergo prophylactic not curing procedure. Think bypass surgery versus lipitor. Since I am experiencing only local overheating I am afraid that cooling space there is already too narrow to allow for acid flow. Another thing, as a by product of acid flush I will get gas, now this gas will naturally go up inside the engine displacing the "acid coolant", in a sense forming CO2 block, and this is precisely where I need to have the most de-scaling action. And one more; what would be better; gentle and slow action of vinegar or fast and brutal action of hydrochloric acid? BTW I did see the information of flushing the Atomic 4, it appears that that engine has special access holes in the engine body so someone can be selective in choosing what part of the engine to flush. The only hole I found on M15 is temperature sender. Oh well, cest la vie. Any comments and thoughts would be highly appreciated.
