lol i do know however its hard to explain without pics, an this is from memory about 3yrs ago-olly actually showed me the difference as when i were there were askin about em and baffled sumps.

My lack of technical jargons really gonna fcuk things up here-theres like a solid tubular piece of steel that slides up and down inside a tube-the solid piece slides to operate pressure relief(moves to expose oilway im`guessing) the std ones got maybe 1-2mm deep maybe 3mm wide recess about half way down the sliding solid piece-the modified one doesnt have the recess its a completely solid piece-what happens is muck in the engine oil builds up in that recess and eventually causes the piece to stick in one position-hence modded one doesnt have it-now im not sayin to anyone take the piece out an get it welded up re-machined bk down at all-obviously if youre an engineer ya laughin

Its no higher flow for ppl reading this its just a safety thing though jun do do a high flow oil pump for scoobys.

If i had an open pump in front of me could show ya but without one in bits its very hard to explain-soz about the crap description.
Best sealant used to date- Fourstar ultimate paint protection *Now discontinued* Rebranded as sonus SFX4 paint sealant-Try some ya wont be dissapointed.
