I just replaced the head gaskets on my 2000 grand am gt. Got everything finally put back together yesterday. When I turned the key on and the fuel pump starting working I noticed fuel jetting out of the fuel line where it connects to the injector rail. I dont know if an oring is supposed to be on there and fell off or what. Anyone got any advice?

The threads on my 00 Grand am Cylinder head, for the rocker arms came out. So I went and got a helicoil. It fit on the bolt but once I got it in it seemed to have shrunk a little. Now my rocker arm wont thread on. Could I possibly use a tap the size of my bolt and slightly enlarge the helicoil without damaging the threads? Please help I dont have money for a new head.

A few weeks ago I noticed that my passenger side floor was wet, so i ordered a new heater core thinking that the problem, well first off where is it located. But now the problem is there has been no other water on the floor but I have no heat and the car overheats if I turn the heater on. I replace the thermostat a few months ago which id hate to do again to much of a pain. Any ideas on which it might be? Thanks.
