Best spray lube to cut through stuck rusty parts? UPDATE

[notfred]

Your motor sounds like a mess. How much do you plan on overboring the thing once you get the pistons out?

Aerokroil FTW.

Try pouring some strong-ass solvent in there to destroy the sludge- and your piston rings in the process. Xylene should work, get it at paint stores.

Well the crank is still in there but I have put a jack on the rod and pushed it up until it starts lifting the whole car.

Yikes, that's scary. Sounds like the engine is going to need a complete rebuild, that's just not normal.

It's VG for wiping tooling for storage. That's all I use it for.

Kroil is OK but stinky, penitrates the skin easily and does not work as well as Nuts Off.
Kroil probably works well on clean machined surfaces but not corrosion. *shrugs*

I have Kroil here but rarely use it. I have worked in the oil patch and diesel salt water marine
and nothing works as well as Nuts Off.

OP, you must get your own Nuts Off http://www.thomasregister.com/olc/50691005/phel9_6a.htm
It's made by Spray Products Corp., Norristown, Pa. 19404. Bar code: 51661 75516
Part# on my 11oz can: 075-516
I provide the above so you can find it locally.

24 hours after being applied, corrosion melts...Period!
I had a boss that restored vintage deep sea fishing reels in his quiet field office. One day
I heard him cursing stuck unobtainium screws. I gave him an employer provided can of
Nuts Off. The next day he drove out into the field to thank me with a cold Arizona ice tea.
The stuff works!

Where does one get this stuff? I did a search and came up with nada.

Can be ordered direct from KanoLabs. I thought it smelled better than other stuff, not that I would use it indoors.

I'm talking about Nuts Off. Wasn't where you said it was.

Well I got the 4th piston out. The center 2 and 3 are moving but will not come out and number 1 has not moved a inch.
I have been using PB blaster. Now that I have piston 4 out it seems to be sludge that is holding them in not rust. Had to soak piston 4 in pure purple stuff to get the oil rings off.

But 2 and 3 piston will come up high enough for me to remove the top piston ring but gets stuck at the top? I have now even used some engine degreaser trying to see if that would help and even jacked the piston up with my jack. No ridge in the engine that I can feel. I have sanded the wall to make sure. And number 1 piston I have no idea.

How about putting a wooden block on top of the pistons and try hammering them out the bottom of the block. Also try putting some ice cubes on the piston before doing it.

Well all the pistons are out. The reason the 2 and 3 would lift the car was that the crank was not able to turn because of cyl 1 being stuck. As soon as I was able to get piston 1 to move a little I shifted the crank and 2 and 3 popped out. Another 1/2 hour of work and piston 1 was out. I damaged some rod bolts in the process, but much cheaper then $240 for a new piston, each.

Now just get the snap ring off the turbo and finish rebuilding that and then I can put the motor back together.

Sorry but the kids already did that after the car was towed to their place. Ryan, the youngest, jumped in the front seat then to the back as soon as it came off the wrecker.

Valvoline Synthetic Lubricant. I went through cases of PB Blaster, Liquid Wrench, etc. I swear by this valvoline stuff.
