    The only situation I can think of would be if the car had bigger injectors installed. The safc would be used to try and shorten the pulse and the PCM would then add timing. But if the injectors are too big then it would still be rich.

    So, I'm a little on edge at the moment. The car has been stored at my cousin's house since TOTD. Unfortunately, my cousin lives in a suburb of Raleigh, which in case you haven't been paying attention, is about to get slammed by hurricane florence. I've been in contact with him, and its been moved away from the trees. I have insurance on it so if something happens, I should get paid. I still don't wanna lose it...lol. Way too much time is in it...although I prolly don't need to tell y'all about that. So, here's to hoping it makes it out unscathed.

    The turd is home! Woohoo! She's a bit dirty from sitting in a tree line for the last 4 months but was great to see her again. Gonna do a compression test then pull the motor. Might start today but I'm super beat from the drive. I'm just excited to finally see what the hell happened at the dragon.

    Those 5 spokes look good on the SL2.

    So finally had a chance to tinker with the turd this weekend. Did a compression test before starting to pull the motor. got 65-230-240-235. I think I know where my problem lies...lol. Same cylinder that fried a spark plug on the way into the dragon. Plan on having the motor out and car tucked away this week. Might not be able to get into it until I finish up the disaster of a roof I'm working on.

    So I finally cracked open the motor last night. Turns out I cracked some ringlands. Well, actually all of them...lol. All four pistons have significant damage. The #1 piston lost the second compression ring as well. I'll take more pictures once I pull the pistons but she's fucked. I'm pretty sure the block will be salvageable, especially since I am at stock bore. I think the head is trashed. #1 and #2 chambers look more like a acne ravaged teen rather a cylinder head. I have no idea as to why this would have started, although I assume that once they started chipping i accelerates quickly. Coming out of the mountains, I thought I was hearing some pinging but wasn't sure. Definitely didn't hear anything while there. I know I often ran rich, anything beyond half throttle seemed to make the computer dump fuel. So, any thoughts as to what happened? And finally some pic

    Ouch! Those look rough, though I wonder why you had good compression on the three cylinders when all four pistons are wrecked...

    Ouch for sure!!

    I need to pull the engine in my 93 (again) as it's go like 90psi in #1, been trying to get motivated as she sits for months.

    Side note, like the look of the big spokes on your car. I usually don't like larger wheels on Saturns but they look good on yours.

    I blew up my first two engines like that, but it was from running too lean. The pistons over heated and the ringlands got weak and they designed to leave the party.
    You have a few options as to what happened:
    #1: running too lean.

    #2: the carbon on top was holding excess heat causing the piston to be too hot.

    #3: The carbon was gooked up in the ring grooves, expanded too much from heat and caused he ring land to pop off to relieve the pressure. This happens on the GM's newer 2.0 turbo and 2.4 non-turbo ecotecs...the new new ones, not the good ecotecs in the Ions. In GM's case it happens with the Mobil 1 oil for some reason.
