ok so it offically locked up, but i did find a really good used engine out of a 98 suburban, it has 80,000 miles and new gaskets fro $600. or else i can get a reman one for $1350 with a 3 year/ 100,000 mile warranty, as for money well im in college so i dont have a whole lot of spare cash, i could have the $600 in 2 weeks and the $1350 in a little over a month. what do you guys think, which one should i go with.
