First of all, remind me to Kill sonoma_zr2 when I see him in MN in about 2 weeks for hiding my air ratchet in the toolbox, instead of on the shelf with the rest of the air tools.

Long story short, after carefully inspecting all 6 cylinders (see page 3 for the borescope images of #1), I found only some POSSIBLE minor damage to the #5, and all the 'loose' material from #1 has been conveniently melted, fused, and deposited in the dished center of the piston.

Consider that I STILL have acceptable compression on the #1 per the factory service manual, I decided to cut my losses temporarily while I obtain a replacement bottom end in better shape (and this bottom end to be rebuilt at my leisure at a later date).

So what I did was install 5 original plugs, a new plug in #6, reconnected my injectors, and swapped out the large 2.3" pulley for a rather monstrous 2.5". I just couldn't bring myself to put a 2.55" on there. I have a reputation to think about.

Hang your head in shame, Bo. We have a 2.5" pulley on the Zilla.

The 2.5" pulley requires me to remove my extra idler. That'* ok, though, cuz we've been wearing it out. I think it'* 2.95" in diameter now, and needs to be replaced with a steel pulley next round.

Car is purring like a kitten. I still need to boost up my octane a bit. By my calculations, the 16 year old blonde chick that dumped 87 octane in my car left me with about 88.4 octane (I had about 3 gallons of 92 in the tank already). I just happen to have a gallon of toluene handy. My net octane in about 5 minutes will be 91.26 until I fill up again with 92.

I'll drive easy for the next 5-10 miles with nothing over 3000 rpm'*. After the higher octane hits the rail, I can drive like those normal people we've heard about. I had no KR on a 2.2" pulley with the ported heads and rockers, so I should be safe from further damage running a 2.5" pulley once the octane is bumped up a bit.

Some pics of the afternoon'* work:

Let'* see someone ELSE try to kill a moth on the TOP of the hood. This was my last kill other than my #1 piston:

Here'* an idea of what the belt path looks like now. Think about a 3" idler pulley being mounted to the hole in the bracket beneath the ICM. That'* what I normally run:

A little fuel pressure anyone? I have some to spare now:

Time to back that fuel pressure off a bit for the 2.5" pulley. And it'll stay there. The next injectors will be a bit bigger when they get here.

I'm going out to dump some Toluene in the tank, and Bo and I are going for a leisurely drive to run that higher octane up to the rail so tomorrow morning'* drive to work doesn't have any surprises.

Sounds good . I am glad you got your car running for the moment till you get a new bottom end. If you miss the 2.3" pulley so much, throw it on the SLE

Thanks, Olds.

10.1 miles on the ticker. Should be in the 'octane safe' zone. Car is running like a champ, and is now off the injured reserve list, and back at least in a daily driver role for the time being.

Don't you have another Bonneville to fall back on? I hope nothing happens to those cylinder bores you want to be ok for a rebuild.
