What's up with my pistons? Pics inside!

Ok I figure with me driving around with a bad MAF sensor for a while that was causing some bad air signals which in turn resulted in the computer sending the wrong fuel amounts to the injectors. Could that have caused this? I don't even wanna know what the inside of my heads look like now

look fine.....other than dirty

Looks good, maybe a litle fuel isnt combusting properly. Its hard to tell on film though. Rather see it in person you know.

i remember when ernan took his heads off he cleaned those up with a wire brush (drill attachment?) is that what you should do here to clean those up, if you wanted to?

Those look remarkably well. How many miles do you have on it? When I did my HCI last summer I had TONS of carbon buildup. Why did you pull the heads?

looks pretty clean to me. use a dremel tool with a wire brush attachment, clean them up. use some brakleen clean and dry them up nice and good. put the heads back on.

I wouldn't worry about cleaning the pistons. The only thing you are achieving my cleaning your pistons with a wire brush is skanking up the cylinder walls and taking chances of dropping some of that carbon into your oil. Neither is a big deal, but neither is necessary either.

I'm going for 351W so I'm parting out the 302. Was dying to finally dig into my first engine. This one has 120,000 on it. I was really suprised how well everything looked. I'm the third owner and I can tell the first two took really good care of this car. Those were the two worst looking pistons. The rest were virtually clean.

I agree with joe... but if you do decide to clean them, bring the piston up as close to the top of the block as possible so you wont skank up the cylinder walls. Just make sure you stick your disty back in so you dont lose your timing when you turn the crank.

Or you can leave #1 at TDC so it will be easy to find.
