Alright so about a month ago i pulled my dip stick and it appeared that i blew my head gaskets or so i thought after waiting on the new multi layer stainless steal head gaskets and arp head studs to come my brother and i tore down the top end and came to find the fel-pro's weren’t blown but there was some how a little bit of rust build up on the deck of the block so i used 180 sandpaper and got it off put everything back together and now after i drive the car for an hour i have to check the coolant usually 4-6 inches low in the radiator its a 2 core with electric fans but even if its not hot i noticed today after i did the 2nd flush to the coolant system that is under pressure and low, got some sealer stuff from Napa today also to try and see what happens the guy also gave me something else so the water pump doesn’t seize up...i just don’t know where its going i check the oil every time before i drive looks good so far...i laid under the car while it ran for 15mins didn’t see and leaks or drips....any ideas??
