Thanks for the info. I plan on pre mixing the fuel so I can run my kicker off the main tank and will be removing the VRO. Would the bad seals on the reset pins cause the oil/ crud to go into the pulse line to the block?
No, that would be a rip in the air pump's diaphragm ...at the very least it would need a diaphragm repair kit...but being so old.....
My concern is it is coming from the block and not the VRO. I haven't had time to dig into it further but just received all the gaskets and plan on working on it over the weekend.
If the oil crud is not in the pulse line, but at the bottom...I would suspect some other gasket leak....which is beyond my knowledge
I have another question. Is there a way to test the overheat alarm.
The simplest thing to do is follow each temp sensor wire, under a sheathing there will be a blade connector that disconnects like a switchblade. Disconnect each one....and with the KEY to ON....ground each one to see if the horn sounds.
If not....chase down why....bad wiring or bad horn.....horn should chirp when key is turned to ON
if so, then remove the temp sensors, get a multimeter, attach the leads of multimeter to the blade connector and the front face of temp sensor....dunk temp sensor into a pot of water along with a thermometer, and bring water to boil.
With multimeter set to CONDUCTIVITY you should have 0 connectivity initially then the contacts close before the water boils.
The motor had to be running hot and I never got an alarm. The upper grommet on the water uplift tube was in bad shape and leaking when I put the water hose to it. This was the reason I pulled the power head. The water tube itself was bent in places it shouldn’t have and pretty beat up. I purchased a new tube and it’s 3/4” longer than the one that was in it because of all the bends. It couldn’t have been seating all the way down in the water pump and it was going in at an angle. I wouldn’t think it was cooling properly and should have gotten an alarm. I also had the regulator, Stator and a power pack go bad. I’m guessing from overheating.
oh wow you are going DEEP
