luckily i caught it early on, called the speed shop and they say that the 2-3 are the most common fail point when you make a reasonable amount of power. He asked what i torqued the Main caps at, I said 65ftlbs..... He told me to check my torque wrench and make sure it is not clicking early... so i did a small test and found it is about 15ftlbs off when compared to my 3/8 wrench.! That means my 65 was 50... thats not enough and the caps may have walked.
Note to self : dont buy cheap torque wrenches
I'm in Canada, so I gotta talk via my phone (which I freaking hate) But...
Are you sure that is an overfill that caused that? There looks to be a lot of heat in those carnage pics....if it were me, I'd be calling my ass off talking to the "experts" out there to see what all if the things could've happened to such a new engine to fail that way
It's how I learned about head lift on my 460 back in my ignorant days.
Back in my ignorant days,..( 1995).. I decided to dump 350 HP of N2o on 9.5cr with 36degrees of timing using pump premium.
I wondered why my freeze plugs were blowing out of the block.
I learned after talking with several experts, ( the last being Alan Moody, of original Holman/Moody fame, )that too little octane, too much nitrous, and too much timing don't like each other)
I had two stages of nitrous stacked on a 1980 Mustang with that 460/c4 and had just brought it out after having had the Cam failure mentioned earlier. I would leave on a 175 shot, and grab the second shot just as soon as I pulled second.
Just as soon as I did that, it would blow a freeze plug.
I should have known something was wrong when winging the engine would suck the lower radiator hose closed
But I ignored it.
I should've known something was wrong when it blew the plug out the first time it did it.
But I went to AZ, and bought an expandable one that night at the track.
And ignored that too.
It took wrecking the car to start to question why....
( 460 head bolts are torqued to 140ft lbs,....it takes a hell of a lot of detonation to lift those heads)
After hauling the destroyed car back home, I started trying to figure out what happened...
I just happened to call moody, and he schooled me,....cause everybody else I spoke to told me that if a head lifts, a head gasket goes right along with it.
Detonation happened..... bad detonation.
And a head gasket stays intact if compression gasses find a way out ( into the water jacket) instead.
The message here is to thoroughly check into why this engine failed...especially when you're saying there was only a little over 6 qts of oil in the drain pan.
