Froze Motor

Guys my daughter let her 74 Nova sit for a year and now the motor is froze. Is there anything I can do about this?

soak it with mystery oil seems like ive heard thats an option, i could b wrong though....

the bbc in my nova froze up i had it in my yard covered up anyway pulled the heads cleaned all debiie with a hohe and wd it was still froze we turned the crank 180 degrees backwards un froze itself it is still in my nova 2 years later

Thought about trying some pb blaster?

The old timers use coke... Yep the stuff you drink. Pull the plugs and pour it in. Let it set.

Trans fluid in the spark plug holes. Leave it for a day and then turn the engine by hand. Back and then forward with a socket on the harmonic balancer bolt or a big screw driver on the fly wheel. If it breaks loose turn it all the way around one time. Hit the starter and blow the trans fluid out before putting the plugs back in. If the engine run and you did it without cracking a ring, change the oil. The smoke will be fun when it first starts up too. It will go away in 10 or 15 minutes.

How do you know if you cracked the rings?

The smoke doesn't go away.

He's right. It will keep on smoking.

Man does Trans fluid SmOkE!

We use to play jokes on each other years ago. One I likes was a little trans fluid in the carb without them knowing. They would start the car and get 3 or 4 blocks before a cloud of smoke would cover anything that was in back of them.
It is good for burning the carbon off pistons in a hi milage motor too.

OK, I will try the trans fluid. Wish I was going to cruise this weekend. Needed to burn some rubber and have some fun. Haven't seen my daughter in over a year so its time to make the trek to Athens Ohio. Her Nova is in bad shape too. Hope this get's it running.

I bought a '67 Mustang coupe once that smoked so bad the guy was convinced the motor was shot. Put a new modulator valve on the transmission and made a nice profit on it.

I have seen that too. The valve goes bad and the engine sucking trans fluid through the hose.

I USED THE PB BLASTER TO UNSTICK THE MOTOR IN MY S10, WORKED GREAT A COUPLE OF DAYS OF SOAKING AND OVER SHE TURNED

Did it come loose?

Yes sir. Only issue now is the fact that it has a pop in the exhaust not a backfire a pop. When you rev the motor up in park it will pop once in a while. Smooth at idle. When you are driving it will pop too. Doesn't seem to be down on power. Ideas. Oil was changed and new plugs put in.

Sticky valve? How long was it sitting?

About a year. Don't think it might be plug wires or cap and rotor? It has an HEI Distributor.

It could be. Could be a number of things. Without looking at it it's hard to say.

brake fluid works great too. doesent have metal shavings in it like trans fluid does either.

Sigh

What kind of exhaust? Running rich, little exhaust leak and some hot gas; she goes bang in the pipes?
Maybe?

That sounds more like the case. It has dual exhaust, stock exhaust manifolds, stock round 2 barrel that always seems to run a little on the rich side. What you propose sir sounds very plausible. I would love to put a performer intake and 600 vac sec on it.
