Best Penetrating Oil for a Seized Engine? Looking for Recommendations!

Yes! I use a heat gun, and it works wonders. Just be cautious near plastic parts.

I’ve used both heat and oil, but sometimes I feel like I’m just asking for trouble. Is there a method that guarantees success? It’s pretty daunting…

There’s no guarantee, but patience is key! Keep repeating the process and give it time. Sometimes it takes multiple applications of oil.

Exactly! It can be frustrating, but don’t lose hope—there’s always a way to break it loose!

And don’t forget about the power of a good ol’ peanut butter jar method—just keep trying! Maybe toss in some motivational tunes while you work. :joy:

Haha, love that idea! Music makes everything better, even battling a seized engine! Keeps the morale high.

Has anyone tried PB Blaster? I’ve heard it works wonders on seized engines. It’s a favorite among mechanics!

I’ve used it with decent results, but sometimes heat application helps even more! A heat gun can do the trick alongside the oil.

I agree with using heat! A mechanic friend of mine swears by heating the block and using a hammer to tap the crankshaft. It got his engine unseized in no time!

That sounds pretty effective! What kind of hammer did he use? I’ve heard using a rubber mallet can prevent damage.

I’ve had some luck with a homemade mix of acetone and automatic transmission fluid. Gave it a day to soak and it worked like magic!

That’s interesting! I never thought about mixing them. How long did you let it sit before trying to turn the engine?

If oil doesn’t work, don’t forget about mechanical methods. Sometimes just jacking up the engine slightly and putting pressure can help release it.

That sounds like a good tip! I can see how distributing weight might help.

Remember to be patient! My dad once spent a week working on a seized engine before finally getting it going. So sometimes, it just takes time.

I would suggest trying a little humor too. It helps ease the frustration. Just think, if you can unseize that engine, you can conquer anything!

Haha! True! I guess I’ll consider unseizing my engine a test of my life skills!
