Thread: Hydro Lock help PLEASE!

I have my battery grounded to my block, oem battery location. We had this happen prior to another sentra, think I could hold the key over and try and move the motor by the pully and have the starter helping at the same time?

you'll burn the starter up like that. You've probably already scarred the cylinders badly by trying to roll start the car.

This is pretty much what we were thinking lol.

can i pour oil straight into the where the plugs go if i remove the plugs? will the oil seep down to the pistons & help it break loose?

How is oil going to help the situation? If you can't move the motor by hand with a long breaker bar, make sure that there's not something external jamming the engine, like the starter, or something in the driveline. Pull the valve cover for giggles while your at it, it only takes a few minutes and you might get lucky and see something.

Does it not move at all in either direction with a breaker bar?

Yeah, something seems strange about this "hydro lock" situation.

You can definitely hydro lock the engine with fuel from bad injector o-rings, but the starter isn't strong enough to impart permanent damage. Push starting it with gas filled cylinders.... will that cause damage, not sure. If it's truly locked up and won't budge in either direction, something is up. Broken timing chain maybe?

Well, he posted earlier that he has the plugs removed and the engine still will not turn over. Never did think about the chain being broken. Sounds likely though.

yeah i tried to move the motor by the pully in both directions with a breaker bar and the pully would either loosen, or tighen up, it wouldnt budge, although when i tried this the plugs WERE in, should i be trying this with the plugs out? I pulled the starter and took it in, starter is still good, i also left the plugs out over night to try and dry up all the gas in there... timing chain, havent checked, should the motor be able to move fairly easy from moving the pully?

Yea chain or guides
