Re: Should I Worry About My Block Being Cracked???!!
the instructions on pressure testing? It just says to plug off all hoses and put 15 ibs of pressure? What do i need to do that do i need to rent something to do this and if so where i hook it to the block at?
If you have the time and the lake is nearby, I would do it as Bondo suggests......splash the boat and run the snot out of it.....watch the oil closely.....
Otherwise,
It's a fairly easy job......You'll remove the hoses that feed the manifolds since you really cannot easily cap those.
Then plug the hose from the transom. Basically the water comes from the transom connection (raw water pump discharge) and goes to the engine (usually the t-stat housing) ............
Water FROM the engine (t-stat housing) goes to each (and thru each) exhaust manifold and riser, and then out with the exhaust.
You have to "cap" the hoses that supply each manifold and the single hose from the transom.
Connect your compressor, bicycle pump etc, can of R-134 refrigerant etc.......AND connect a gage to any of them using what ever "junk-box" or "HomeDepot" plumbing nightmare you can assemble......Any sort of pipe will work, galvanized, black pipe, plastic, etc..... 15 PSI is more than enough. Ensure that the compressor (if used) is off and it's otherwise quiet and listen!
If you're lucky, you won't hear anything........(unless your plumbing nightmare is leaking!)
If you're not very lucky, and you do hear leaks internally, then your block was more than half full and you may have internal cracks. Pull the intake manifold to inspect.
