914 has been sitting too long. How do I turn the motor by hand?

[pinetreeporsche]

Yeah- my fault. Car needed a new fuel filter and probably the gas tank cleaned, so didn't get it running. For a couple of years I spun it w/the starter once in a while- after recharging the battery. Won't spin at all now- presumably a bit of rust on the cyl walls. I've pulled the plugs, inserted fat drinking straws into thee cylinders, and poured in lots of WD-40 and PB Blaster, etc.
But the flywheel nut that's easily grabbed with a wrench on non-midships Porsche 4's-- and VW air cooled (and waterboxers) can't be reached So I jacked one side of the rear, and tried spinning the jacked wheel by hand-- but no luck. Then took off the jacked wheel and tried a lever between two of the lug studs, but without major fabrication, I can't get much leverage this way either. SO- Anyone got other secrets for breaking the bond between rings and the walls?? Yeah, considering putting an electric heater under one pair of cylinders, adding more Blaster, then the other, but more leverage seems lick the ticket. Thanks for any help!

What gear did you put it in?
If you jack up one wheel and put it in 3rd or 4th you may do quite a bit better.

That being said.....if it takes this much effort....then its more than just a little rust on the cylinder walls.....and if you have that much crap on the cylinder walls....turning the engine over is just destroying the rings and bore.

Time to tear it down. Getting it broken loose is not going to buff out the damage caused by a rust ridge. Ray

if its on concrete I'd put it in gear and rock it back and forth in 2nd gear. If it's heavily rusted oh well time to replace the pistons and cylinders.

Remove the plugs, put in 4th gear and turn rear jacked up wheel backwards, if still no luck make a mix of 50% acetone/atf. That mix will break any rusted parts loose.

Marvel Mystery Oil is a great penetrating fluid. Fill plug holes and let set couple days.

Always turn backwards after putting any fluid in plug holes to keep from bending a rod as backwards will push excess fluid out the intake valves.

curious.... did you get it?
