Reply to "Mangusta Freeze Plug Leaking / Blown Out"

bosswrenchMember

There are six and few can be done with the engine in place. There's only about 10-20 psi ever developed inside the cooling system, and that high point is only momentary. If the blown plug is not rusty, someone installed one incorrectly. There have been millions of SBFs made and very, very few actual plug failures.

Hammering a plug in will distort the shape and relax the wall tension that actually holds the plug in place. Some use epoxy, RTV or other glues when installing but that's unnecessary and makes a real mess to clean out when replacing plugs. THere's a rather complete article in a recent POCA Newsletter on this very subject.
