hi
got a 4 speed tranny but no 5 sorry

thinking this thru a bit it seems to me that adding more spring or taller pistons will only give higher oil pressure when cold once the oil is hot and able to flow easier it strikes me as it doesnt make much difference as the piston is not being pressed of the seat anyway or?

this is where the seat becomes important that the oil cannot get passed sneekily while it is actually seated is quite important for warm pressure .

at the moment i see just under 5 bar cold and when at start up this gradually reduces down too .5 bar 7psi at hot idle after a long pull i have not seen my oil light on and i have not checked the acuracy of my vdo either so it could be off either way by a bit?

my sender unit is screwed into a typ3 adaptor that is screwed into the top of a 5 cm tall brass adaptor screwed into the original oil pressure sender hole now it stands to reason to me that i will be showing a lower than actual pressure at my gauge with my sender just horizontally level with the base of the distributer cap base (am i making sense) .

this is the highest point of the oiling system higher than my cooler which sits to the left hand side of the tranny.

with this in mind would it be safe to assume that everywhere else will see slightly better pressure ?

im not overly concered at the moment ive a stock oil pump stock possibly tiered spring and piston and was thinking that i could at least put in a new piston and spring and if i can get hold of the tool reseat the piston seat to allow for the pressure drop i get by running an oil cooler thru a filter mounted sandwich plate adaptor.

i have decent stainless covered braided 13mm oil lines to my cooler and they are relatively short but even here there is a possibility of some buldeing (sp expanding) in the heat of the summer .

it would be reassuring to know im as good as brand new stock oil pressure if not slightly better but i completely agree that to much pressure is also not a good thing.

be good.
