A gentle note (ie, I'm not trying to be a **** or anything), but I see the common occurance today on the forum among other posts (this one too) where folks are having gasket leakage problems or in your case a dire situation of broken gasket during major surgery.
The first human tendency is to want the quick fix or the cheap fix when in actuality, we (I mean everyone) needs to understand the risk we are taking by going the cheap route:
1: Cheap fix is indeed cheap, but doesnt work. Result: gotta do it again anyways with the right part.
2: Aftermath of cheap fix: oil everywhere, and possible fire and or engine damage due to loss of oil.
3: End cost of cheap fix: 72.00, plus a second afternoon of taking the engine apart again to repair.
Cost to fix it right the first time: 72.00 from autozone and you get all new seals for plugs and valve covers. Never worry about leakage for another 60k. Yes you might have a delay, but even Rock auto sends me stuff within 2 days. I got the intake gaskets that I ordered on monday on my doorstep by Wed.
So the question bears asking: what is your time worth, and are you willing to work for less than that.
IF you dont have time to do it right, where will you find the time to do it again?
Sorry if this sounds harsh. Just trying to share some life experience here so that you save yourself some time and headaches.
