RE: 406 Oil Pressure Relief valve
By John Saxon - 07/08/2003 11:45:49 AM; IP 167.147.32.129
A guy gave me a call a few years ago asking about the same problem with a freshly rebuilt 427 topoiler after having him describe how he installed the relief valve plunger and spring and consulting some ford drawings we decided he must have installed them incorrectly,he had to drop his tranny and pull his flywheel to get to them but found that they were indeed installed incorrectly and proceeded to reassemble it the right way and presto he had 75lbs of oil pressure.I will try to dig up the drawings of the back of the block and how the relief plunger and spring are installed and try to get access to a scanner to post them,hopefully Shoe will read this and he may be able to post it quicker,I don't even know where to look for a scanner to use.This guy had exactly the same problem though,new 427 with 7-10 pounds of oil pressure at idle.
This thread, so far...
