Just a question. What does it mean that someone has a "sealed engine". I have heard this several times and never asked what it means! Does it mean that there is a tamperproof tag or something of that nature or a special color of permatex sealer....Just wondering.

My inquiring mind wants to know!!!

Has there ever been a case where someone has gone into an Engine and made mods and "sealed" it back up and got caught?

Thanks in advance,
Craig

i think it means the motors are sealed off to keep them clean..?? we have some lycomings that are sealed right now.. in big boxes that you can't see the motors.. look like the big rubber made containors

What I'm talking about is for racing, I've heard people say that the engines are sealed for F1 or F2 class racing? Unless I dreamed it or something

Well if its a race motor it will have some type of tag through a few different bolts so you can't take it apart without them knowing.

If it's just a motor at a shop it most likely means its on a pallet and in a bag or something like that.

As far as people getting busted taking tags off, I would ask Fever Mike.

All the ones I have seen on race motors are a piece of wire through some bolts sealed with a lead stamp thing.

Thanks, I was just wondering how they did it.

Most teams have 2 seals.

Have you ever seen those little lead weights hanging from an electric meter? They usually have some numbers stamped into the weight. Well a sealed motor has one of those going through the intake manifold. That way you can't take open the engine up to modify it.


Custom was right though. The military will rebuild an engine and then "seal" it. I've heard of people opening crates that were sealed in the 50's and the engine is like new. I believe they even pressurize some of the crates.

Thanks for the info!!

In the past if the military didn't think they were going to use some piece of machinery in 30 days.... it was "sealed" and what that meant was it was dipped in some **** called "cosmolene". It looks like brown tar and grease mixed together and sealed the surfaces from any exposure to air... easy to remove with solvent.
