Dry Ice and the LT5

[Russ]

I will be doing the dry ice treatment on the undercarriage etc on the 91 once weather permits driving the two hour mountain pass route, and wondered if anyone has experience enough to comment on a lighter dry ice treatment on the engine itself. The engine bay should be fine to do. The engine has some light staining and is not that bad and the original finish appears intact but it is not a clean as it could be. If it is a disaster waiting to happen I will go the various successful routes many have described here. Starter valley etc already cleaned during resurrection. The lt5 looks so nice when spotless.
