intake leak????

RE: intake leak????
The common intake oil leak makes no noise, it just makes a mess. An air/vacuum leak in the itake may or may not make noise, but it will make the car run bad. If it is bad enough to make noise, it is usually a high pitched whistle.

RE: intake leak????
The reason that most LT1's leak from the intake manifold is either a bad casting or the bendable little tube right behind the intake manifold(egr?) is too close to the gasket and needs to be pulled away, and heat wrapped. I youve ever fixed one you can see a yellow stain/burn mark on the seat right by where that tube would be, its not a problem if the mark is there it just confirms that it was the culprit. usually the rear left if looking at it from the front.
