"high cylinder pressure will push the rings into the piston and cause blow by"
Simon can you explain why? As for the past 30 years I've understood it to be the complete opposite. I'm not saying run loads of boost
in fact the boost is immaterial higher cylinder pressure forces piston rings out not in. I'm confused......However Tims been instructed to run his engine in is what he should do....but on the technical side of this I'm interested as I shall soon be building up my 2.5 soon.
No I haven't built a Subaru engine but I have built numerous others, but all n/a engines. Thanks
