    Oil Pressure Alarm

    Sometimes the float in the gear oil bottle gets goobered up and gives constant alarm, even when full. 3 possibilities: Lube oil alarm Oil pressure alarm High engine temp. All 3 are the same alarm with 3 sensors in parallel. Disconnect one at a time to see if goes away.

    Oil Pressure Alarm

    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.

    ‘96 mercruiser power steering leak,

    It was a hose on mine, down low where you couldn't see it

    Trim Hydraulics

    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.

    Topped off battery with Distilled water....Why not with battery acid???? Opinions???

    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...

    Topped off battery with Distilled water....Why not with battery acid???? Opinions???

    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...

    lifter issue and rock arm registration

    Nice work and congrats on sticking it out to completion.

    lifter issue and rock arm registration

    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.

    454 dies over 1800RPM loaded

    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...

    lifter issue and rock arm registration

    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...

    Great. Now you get it all back together and run it like you stole it.

    You should be OK, then, with the resistance readings on the hand held meter.

    lifter issue and rock arm registration

    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...

    lifter issue and rock arm registration

    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...

    Puffing steam out vents

    Question: Has that been run in salt / brackish water? If so, that aluminum manifold will not hold up in those conditions and can corrode the water passages pretty quickly on a raw water cooled engine. Other than that, some of the cyls (6 and 8) show signs of head gasket possibly leaking by...

    That circled valve also looks tuliped and too deep into the pocket.

    Going straight at low speed?

    All Deep V's with single prop I/O's wander to some extent, even brand new, unless mods have been made. Nature of the beast

    2002 5,7 Mercruiser exhaust manifold keeps cracking - 5 times this summer

    Yeah, zoom in real close and look at it. I would be sending to shop to see if it was any good. Looks like seat isn't touching casting in a spot. Could be the pic. Never had a valve job done that looked this bad.
