okay so the last couple weaks my antifreeze has been gettin low and i couldnt figure out where it was going, but we did an exhaust/chemical test on the coolant and it came out positive. do these LT1's usually have problems with the gaskets, hadnt thought so. anyways i was wondering if you guys think its just gaskets or head cracked, or no way to tell till i rip it apart. it never got hot, and never hydrolocks, just burns a little antifreeze on about a 120 mile trip, maybe a quart? anyways put some sealer in it , i know i know, but gotta try and get by till christmas break from school so i can do a complete top end rebuild. thanks for any help
