Strange "Void if removed" marking on shortblock.
A question was asked a while back in the Rotary Tech and Performance section about a marking that was found on an engine that read: "guarantee across top and 'void if removed' across bottom"
I have a similar question about a lable on a motor of mine. The engine is supposed to be a 2001 JSPEC engine, and this seal seems like it may be evidence to the contrary. I am aware that it could originally be a JSPEC engine, that was in the states for a while, and eventually rebuilt by an american builder, but with the ammount of miles said to be on the engine, that is almost impossible.
So the question remains... does anybody have any information about such a mark on a shortblock? It's located right above the spark plug inlets.
Here is a picture of the motor it came from:
Thank you in advance for any ideas you have about this mark and or engine.

I have never hear of such things on a rotary before. I have seen piston engines with a wax type plug in the freeze plugs and if that melts they do not warrenty any thing on the engine, becouse it shows that it was over heated.
Were did you get the engine? Were you running it in your car or did you just recieve it?

Interesting...
Excellent insight, I will try to get a better high res photo of the marking tonight. (The camera that took these pictures pales in comparison to the shop camera)
The engine was received in short block form, from another forum member, and has not been installed yet.
There does not appear to be any "Wax" around the plug, but it looks like it was JB welded on.

hmmm
[I apologize, I made this post as a response to an old question in the General Rotary Tech Support too]
I understand that it could be a overheat indicator... but...
I spoke again with another party that was in the shop last night, and he makes some good points.
Firstly, the position of where it was welded on seems to be significant. " It's right on the rear iron->rear housing border, so if you tried to take the motor apart you'd have to take it off."
Also, it really looked like it was JBwelded on, and not fitted with a glue or adhesive. This seems pretty pointless though, because anybody who would take the engine apart could just weld it back on...
I will post some more high res photos tonight that may provide some more information. Is it possible this is anything besides an overheat indicator, such as a "I was cracked open and tampered with" indicator?
Is it highly probable that this engine was been in the hands of a rebuilding shop, or mechanic?

Did you get it from an engine importer? These places usually put these types of tags on their engines in case the customer overheats the engine. Are you sure its actually JB weld? My buddies have had these tags fall off while pressure washing the engine with an electric pressure washer.

Got your PM's, haven't had a chance to respond.
All Jspecs I've seen have had that tab - I believe it will melt, discolor, fall off, something if the engine is run hot, etc. The engine importer likely put that on to cover themselves against a negligent install. This is NOT something Mazda themselves have ever done on a stock motor. But, considering the bulk of Jspec motors coming into the country are through various Japanese engine importers, that's not anything to worry about.
