again, thank you
I am so thankful for you links and tips Rex, I just ordered some bushings for the IRS rebuild for now.
Spent the morning reading and learning more. Than I had went over to samba to look up some articles about the pressure relief valve.
I got more of an education than I expected, read a lot of questions and answers, took piecing together this and that to figure out what might be going on with my engine.
First off, when I decided to put the temp. sensor in place of the plug to the pressure relief valve, well it dropped out and I could not tell how it went back in, flat side first with the cup side facing the spring is what I gathered as the proper way it sits. The control valve is same, flat side first with the cup side facing the spring.
The diagrams I looked over were not 100% the engine and oil route, so a question ?
Does the control valve actually control the flow of oil through the stock cooler that is mounted in the fan shroud, or is the oil always flowing through the cooler ?
Now if I have the, lost the name, adapter plate that covers the original cooler mount, for the external cooler, the bottom line out of the fan shroud is the supply line of oil ??
and than the top port would be the return line from the external cooler ?
I also had water drain out of the valve covers when I had checked my valve clearances the other day, but no sign of water in the oil I drained out of the engine. And the white oil/water film was present, really got me wondering how water got in.
My mind told me condensation, water from the air. Still not sure where it came from, but today I read about how if the pressure relief valve spring is to strong, keeping the valve closed, than a back up of condensation can occur and as the engine and oil heats up this turns to steam and increased pressure can cause the valve to open. This makes me think than all that crude goes into the oil pan.
regardless, I checked more as I read and it is a long chromed spring that takes a lot of strength and pressure against to thread in the plug or sensor, they both are the same length, so as I read I found the chromed spring is aftermarket spring to improve oil pressure, basically stronger than stock so it keeps the pressure relief valve closed to long, and that is not stock operation.
So earlier I took off the hoses and removed the breather box to see what it looked like inside, and of course clean it up, have new hose on the way.
than I had to look inside the box.
So the real question is, does this crude come from the valve covers up into the breather box, or does it come from the breather box down into the valve covers ?
Yes the oil fill tube has the vent port and the hose ran from there to the breather box, so is this the path it takes to enter the breather box to accumulate and than it drains down into the valve cover's ??? lost on this one.
I do know I spent some time cleaning the extension tube of the fill tube, the vent port was just full of the white oil/water crude, or is just the foam created by water/oil and heat ?
I did not look for the sensor adapter that would allow it to be inline to the oil cooler, not yet, but if it is not available, I think I can make it, 1/2" dia hole drilled thru the block, tape threads for the nipples, come down center from the side drilling and tapping the sensor port. In line sensor mounting block, or is the control valve plug the better location ?
