Piston Slap.

89GT2.3H · 05-03-2007

I think my 2.3 has piston slap going on. When it's revved in neutral
it knocks when it decelerates.
The real question is, if I drive like I have 2 braincells firing at a time and don't go all nuts, keep it in town at low revs, will it last a month or so until I get my 2.3T put together?
I really need a car for arround town so i can go to work and not worry about chauffering my wife.

It may last for a little while.........I would drive it until it dies personally.

If it is just piston slap it will last for quite a while. Look at GM 3.1/3.4L engines. Some came from the factory with piston slap and they run for miles.

I'm with Hotwheels. Drive it 'til she wont drive anymore.

I would say thats more like a rod bearing going bad.

I've only heard piston slap on older engine/forged piston combos. Oil burning usually goes hand in hand.

Noooooooo! Not a rod! Why, that won't last more than 3000 miles!

Just drive it. My 89 smokes a little and I get some slap too. I also drive it 60+ miles a day in the mountains going to work and back.
