496 hydroloc help. Help help
 

Plugs out can I roll it over with out disconnecting he ecu to prevent damage to it ?

so motor is a 2002 496 one of a pair in a formula cruiser.


water in 2 rear cylinders on port side . plugs out of the whole motor , riser off .

Question is can you crank it over without the wires and plugs atached.

will it damage the ECU without disconnecting it?

yes turn it over no it wont hurt anything

yes what?

I would roll it over by hand first then shoot wd40 in and give it a spin. If you have a teather just pull it out and hit the starter

so there is no way the water came from the riser as i can see as it is not a open design like i envisioned on the old 454 i am used to

is this year motor 2002 known to blow head gaskets it has 500 easy hours on it.

Does not have safety tethers.

Next idea?

With plugs out, This is a good plan, after that check your oil for milk.

just make sure the plug wires aren't close to anything and give it a turn.. When did you notice it was locked up?

i fired it up with the rear 2 cylinders plugs removed and it fired right up and blew water out

problem is i want to crank it and pickle it and i was thinking we are just drawing more water up through the outdrive intake and filling the cylinder again.
