Question
Coolant is leaking into cylinder #3.  I am told the head gasket is ruined and it cannot be replaced. The only solutionis:  the engine must be replaced.  True or False

Answer
There is a very well known problem with the steel head bolts stretching out and even stripping out the aluminum threads in these engines and I would strongly suggest that you REPLACE the engine and make SURE that the engine has been modified correctly.
