Turbo 3.4pr
Moderator: Series8217
The latest update. Greddy bov installed back at the beginning of December, just in front of the TB by Abel Racing.
Now the good stuff. Piston #1 90 psi. This sparkplug kept staying wet.
Piston #5 150 psi. This sparkplug looked good.
The backside and #3 all had 150 i think psi also. All these plugs looked good also. I am going tto put it back together so I don't lose any parts and tow it out to a buddys house. He has a lift(and a heated garage) to drop the cradle. I also got to get the transmision redone 4t440. It is at 1900 at 70. I want it around 2300 if possible.
I got some scans for Ryan before it blew up. He didn't like my IAC numbers. So I recleaned it and reset it also. It broke before I could get any new ones. It sucks breaking it before I even get on it once.

The pictures are in the right order.
I expected #1 to look like #5. #1 was the only dead cylinder on it when I'd pull a plugwire off with it running. When I was coming home from Abel, I got off of 240 I let off the gas and there was no traffic coming, So I got back in the gas, thats when the motor turned into a paintshaker with a can full of marbles. The detonation thing is a bitch.

Camera was at wrong setting so they're kinda small.
Some updates,couldn't get it to my buddies shop as he was down for back surgery. So it is being worked on it in my garage. Got the pistons, out thought I would be able to just put some new ones on...
Remember these guys, 1 and 5...
they have a friend, # 6 piston doesn't look too bad
The good stuff #1 rod
and #6 rod
The bottom of #1
Looking for some forged rods now.

Bent rods are a good sign of preignition. I'm very surprised they went instead of the pistons though. Either you have extra HD pistons, or extra weak rods.
What were you running? It sounds like everything was wrong.
Next time - run plugs a couple ranges cooler than stock. Use a wideband to make sure you're running OK AFR wise. If you were using the stock fiero computer - ditch that shit! They can't handle boost safely, IMHO. The 2 bar patch is just a patch.

Not sure how you came to that conclusion, but that wasn't the cause.dgzfiero wrote:The only thing I can think that would be the cause would be the running it without the BOV even if it wasn't turning too many rpm's it was still too much for it.

Got it running again. Only had one oil leak, the distributor. Apparently you can only use the o-ring one time. Timing is set at 10 btc. Now to get it up to AbelRacing for some computer work without blowing it up.
It took a month to get a set of rings for one .020 over piston :cussing: . Finally got the last piston in and no exhaust gaskets. They took 2 weeks to get in Damn flyover state.
