Can the 350 engine be unlocked by pouring kerosene in oil tray?

Intake manifold gasket (lower).

First thing is to check your trans fluid level. When checking it, do a inspection of the fluid. It should have a nice red color. If it looks brownish, and smells burnt, it needs to be changed. In addition, when was the last time the filter and trans fluid was changed? Over the years, the vecosity of the fluid breaks down, and causes the valves in the transmission to stick or get sluggish. One trick I had seen used BUT I am not recommending you use it, is to get about a pint or two of k-1 kerosene, and with the engine running, pour it in the transmission, and run it through the gears, and then drain the oil and replace the filter. The kerosene cleans valves and ports in the transmission.

since they are stuck open well then all you can do is pour something into the oil like in old days . we used kerosene . or gas an let it set a few days then turn it over a few to break it all loose.
then drain it out of the oil an let set to get out fumes.
run some high detergent oil or cleaner when you have it running again.
some times we poured in some transmission fluid into the carb to burn . cleaning a sticky gooie engine is a tricky task.

carefull slow running if the oil is over filled with anything.
it takes time to break up gunk.
open each sparkplug hole an spray stuff up in it.

get some marvel mystery oil and pour a couple of ozs. in each cylinder and let it set for a day or so then try to turn the engine by hand in both directions when it moves a quarter turn each way then try the starter

"The rear main bearing seal? This is expensive to get at, about $1000. Unless the oil is pouring out I'd just put a drip tray under it and top up the oil occasionally.

These will help.Thanks.

don't understand how you got some much sludge in engine- but you can try the older sludge treatment- DO NOT START ENGINE WHILE DOING THIS OR BYE_BYE!- drain oil- pour in about 1 gallon k1 KEROSENE- til it show full or better on dipstick- WAIT 24HOURS- drain and change filter- work on a POWER WAGON with 385000- REPEAT_DO NOT START WHILE KERO IS IN BLOCK!

If you mean frozen as in, the engine is locked up due to water rusting it together, you're in for a LONG hard process. I'd order a good 12-pack of Aerokroil from Kano Labs, and ~2 gallons of it Kroil with graphite. Dump contents of the oil pan, and make sure it's all cleaned out (leave the drain plug out, pour kerosene/diesel down the oil filler, let it run out, should clean it out by the time you get 1/2 gallon). Put the plug back in, pour in the kroil. Pull out the spark plugs, and spray each spark plug liberally (With a full can) of AeroKroil. Now, on the crank snout, most likely the main pulley, there will be a bolt. Get a socket to fit that bolt, and then get a long ol' cheater bar, put the socket on the ratchet, and every day spend 20-30 minutes man handling that cheater bar. The rest of the time, put a bungee on it to keep some pressure.

when you flushed with kerosene and diesel you mixed the same two things together,,,, I don't ever do this because it loosen up debris and gunk and deposit and puts them where you don't want it...if you are concerned then change your oil more often....the one time i did do it I added kerosene to the oil that was still in the engine and ran it for less than 2mins...its scary...the problem is most likely the lifters (tapits) it is far better to let them go than flush your engine like you did.....let em go or put new ones in....hope this helps

no-please change the oil filter, the micron size on a typical engine oil filter is 20 micron-cleaning with kerosene oil will not remove any traces of wear particles
