Re: IML: Problem with exhaust manifold studs...

["howard" <parkerc@xxxxxxxxxxxxxx>]

Hi Rob and All,
Concerning your manifold Studs:
I know you said that you used a penetrating oil but Wal Mart ( and others) 
sell a product called
PB Penetrating Catalyst. It comes in a TACKY LOOKING spray can that I would 
have never bought except I wasn't paying attention to what I was doing. At 
any rate I used it on my
65 LeBaron (broken manifold stud) as a last resort and it worked along with 
cutting a notch in the top of the stud and using a screw driver to back it 
out.. Sprayed the BP on it (stud) a number of times over a 24 hour period. 
IT WORKED! I work at a body shop a few hours after school and have used this 
stuff with good results when Liquid Wrench and WD40 wouldn't. Hope this may 
be of help to you....it has worked for me.

Best of Luck,
CHAD
65 LeBaron
