Head gasket in a bottle is not a long term solution. Search forums, videos and buy a repair manual to see what is involved.

how long will it work for?

takes a bit of muscle...you may want a mechanic to do this.

i have plenty of strength...so if engine block test cofirms leak....the last i checked it appeared to be firewall side....sideways mounted engine...can you get to it without pulling engine? its the tappet cover right...or is it in the middle on that.

can anyone reccomend a video of this particular motor and model of this car if possible..i cant find any on 3.8.

may be a little heavy, and greasy...don't drop it! Clean the surfaces and remove carbon with a small wirebrush.

should be able to forensically tell where she blew---thar she blew---on a trip to LA saw the head of tne isuzu impulse sweating out gasket, and to my surprise, the headbolts WERE loose, fancy that 350 miles from home.
