spring oil pressure relief valve P/N 21352


Philippe - doesnt that relief valve control the upper limit i.e.
opens at pressures greater than 35psi? - Mike

I agree but with a very weak spring, it work for me... Why not try
this first? ....


If you have a weak spring, your higher power settign OP will also be
low.

Yes, it was...



oops, sorry, he didn't say it was normal, but he didn't say it wasn't...

Bertie - my upper OP is within the limits of 10-35PSI.

your pressure above idle should be 30-40. If it's below 30 you don't have
enough pressure. 10 is the lower limit for idle only.

It's my OP at idle that concerns me.
Specifications for the A-65 show an acceptable range of between 10-35
and I'm concerned I may be below that range at idle ( at operating
temp).- Mike

Do we all agree that a pressure relief spring probably will not figure
into the fix for the problem of raising my OP at idle? - Mike

might do if your pressure above about 1,000 rpm is less than 30 once your
oil is warm!
