i beilve its so much pressure in the cyl that it blows right by the piston rings. but i could be wrong too i got my info second hand a long time ago from an old engine builder.

washing out sounds like too much fuel and you ruin your rings....just a shot in the dark though

yes washing out the cylanders has to do with to much fuel that it just forces it past the rings

with my mods can i wash em out?

i havent heard of wash out problems (i'm sure there's more) other than extensive low rpm idling, lugging, extended crank time and REDICULOUS fueling... something a sled puller would be modded for. washout is as simple as it sounds... the diesl fuel dilutes the oil film on the cylinder walls increasing friction and wear. actually i've read in principle; the design of a piston ring will increase how well it seals through pressure differential; low crank case pressure and high chamber pressure results in a better seal.

i blew a head gasket and now have studs i wish i would have had the extra money at the time of repairs to have it o ringed its the only way to go


and no that i'm trying to get twins water/meth and nitris

i really hate thinking about the decision and what i have to do over again and truck down time head gasket etc.....

live and learn save up and do it right the first time

or do what i do learn from mistakes , have a bunch of funn, and waste more money because i didnt have enough in the first place

Washing a cylinder is when you have a injector issue and the cylinder is filled with more fuel than it can burn,thus it ends up being pushed down the cylinder walls past the rings and into the crankcase.It will cause premature failure of your rings and will cause them to score the walls also.Most times on a 12v its done because a injector tip has been broken off or blew off and the sparay pattern gets compromised severly.

When you have a coolant issue in the cylinders and it either will not start or while its running it fills the cylinder and bends a connecting rod thats considered "hydraulicing" a cylinder.

Either one is bad and if they happen they will lead to a rebuild.

so if you are building more that 35 psi of boost and do not have head studs you are on borrowed time with you motor and how would you be able to tell if you are washing the cyclinder and are o ringed and fire ring head gaskets the same?
