So I get to change head gaskets on my sister's '95 coupe... again... but my question is: Why have I been told that you need to trim a 'drain hole' in the updated gaskets when using them on the '95?
Last time I did this 6 months ago, I know I didn't know to trim a hole, but I also used just your basic FelPro perma-blue or perma-seal gaskets, whatever was in their head-set, along with new FelPro head bolts, and the b*tch sprung a leak after only 6 months and maybe 6-8 thousand miles.
Was it an error on my part... maybe, but I've done many many head gaskets in my time, and I've NEVER had one fail before (minus on a blown 10-second GT, but that's a different story having to do with mixing forced induction and nitrous). Did I miss something, maybe. Was it due to damage to the heads that I didn't see? Maybe. Was it because I didn't trim this 'drain hole' in the gaskets? Well, since I didn't know anything about it, I guess it certainly could've been.
Thanks all.
