How do you fix this?

I have had the same issue. For me it was a dab of DUCO Cement applied with a thinned out Q-Tip. It has  not lifted off since. I imagine that most glues would work

This is a common issue for me anymore.  I use CA gel (little dabs will do ya) and good as new!  Sharp engine by the way!

OK, thx guys. I have some CA gel. I guess I'll use a tooth pick and drop few here and there...

 

Yes, the Engine is beautiful, thank you. But I need to figure out why the dual smoke fans are not running but the heat is on....I'll check in later...Cheers!

Just make sure it's not enough to squeeze out and leave unsightly marks, they're permanent if you use too much glue.

 

I would use an exacto knife and very gently finish removing it from the shell first. It will probably make it easier to get it to lie flat when you re-glue it.

I have had good luck with this on most plastics. I use it on Ameri-Towne kits and other similar model kits. I have glued one snow plow for a Lionel engine back together with it. Unfortunately, that damage was self inflicted.
