Rick, If you have great luck with that pressure...good for you. The washing I described has nothing to do with coolant or gas, I am more than familiar with both those circumstances and byproducts. I've been building engines since the 60s, all kinds, and all rpm/size/hp ranges and I won't run that high pressure ever, no matter what you believe. Until I have an engine fail, and I haven't yet, I will build them the way that has worked for me for the last 40 years. You should do the same. Just for the record, I have used full grooved mains since the 60s, they are nothing new.
