I would install a cheapie ol mechanical oil pressure gauge in a "T" where the oil alarm sender sits, pull the spark plugs and spin it over with the starter.
That'll tell you if you have oil pressure / wiring problem or not and if it's just a bad sender or a bigger problem.
Don't forget the impact relief valves built into the pistons themselves.
If the ram is really corroded at the gland, those reliefs can blow off the pressure from the supply to the return side.
I dont know, but the old battery tenders used to boil them off pretty bad. But these new computerized "maintainer / chargers" don't seem to do that, as they are pretty precise and low powered.
My tractor and boat batteries haven't needed any water added in over 3 years using a modern "battery...
The #1 rule is and always has been :
Add water to acid, NEVER add acid to water". Adding acid to water causes very bad reactions. But that is for concentrated / undiluted acid.
If the acid in battery didn't boil off / spill out, it is still in there and just water evaporated. Adding the...
May take more than the 10 seconds to get oil thru all of them. Squirting the oil on the rockers will assist in the lubrication until it feeds properly on it's own.
Vacuum gauge needs to be on a running engine to be of any use. If going through all this, I would use a pressure gauge on the outlet. That will not only tell if the is fuel pump operation, but will verify it is correct or not.
Please be careful working on the fuel system and have a fire...
If you didn't clean out the pushrods, all bets off, but they may clean out eventually. That oil is basically there to lube the pushrod to rocker point of contact and the rocker arm fulcrum under the rocker arm stud/nut.. should be spitting out the holes if everything was properly cleaned.
If...
The oil pressure should be 45 psi at over 2000 RPM. At idle, I have some worn engines with 25 PSI (or lower) at idle and still run great. It just means there is some bearing wear.
The oil should be squirting out the little hole in the rocker where the push rod is. Oil is fed up through the...
The rockers sliding back and forth when valve is in the closed position is perfectly normal since there is very little tension on them like that.
There should be oil on the rockers after a few seconds of running / building oil pressure. I suggest putting a mechanical gauge on the the same spot...
