Cut your losses. The only time you want to invest that kind of money into a car is if it will eventually become a classic or already is a classic. I do not believe the Bravada will ever be considered a classic vehicle. 

IF you go ahead..a rebuild is going to cost you a bit...in Canada @ 1500+ bucks...do a price comparison as the low-mileage replacement may be far more economical..problem there is you won't know how good the block is until you R&R it! Also consider the long-run...is the Olds a gas guzzler? When will the next issue occur and at what cost?...used vehicles are a toughie...good luck with this one. Peace.

Here are some reviews for you Woofer, to

help you to decide whether to go forward or not.

I tried several forums for you also but when people

asked for help, none was forthcoming.
