Question replaced head gaskets, coolant leak.

im ASE certified so i have knowledge on this subject but this is my first time replacing head gaskets on a corvette engine.
its my GFs car, 1995 LT1 Camaro 130,000 just replaced the head gaskets.
i had a leak coming from the banjo bolt that holds the coolant line to the drivers side of the head.
i replaced that bolt but there is still a little leak.
i think i might have missed something that goes in the back of the drivers side head.
so what all goes into the back of the drivers side of the head????
banjo bolt and what else?
picture sure would help!

Re: replaced head gaskets, coolant leak.

I had one of those banjo bolts leaking on a customers car a few weeks ago, tried replacthing just the gaskets but the coolant still kept on pouring out of there ( somebody had just done a head gasket on it and rounded off one of the banjo bolts head and reused the old gaskets). Since you can't get them banjo bolts from gm I just told the customer I had to make a new line and did something like thishttps://www.camaroz28.com/forums/lt1...cement-793480/ After I got all the pieces rounded up it only took about 30 min. to do with the engine in the car and will do it to mine if it ever starts leaking.
