Well for a while now I have this nasty noise when I start the car up in the morning. It usually lasts until the car is warm and then it goes away. Which alot of mechanics and others are saying this is most likely piston slap. The motor is a 94 JDM H22a that was rebuilt and installed by previous owner. The thing is it started happening after I had the distributor replaced (H23 external coil, with a TD-61 distributor, supposedly same distributor). Would that have anything to do with the noise?

Also say I am in 4th gear going about 40mph, when I shift to 5th it makes the same noise. Or when I am going over a speed bump, and while slowly rolling over I keep in 2nd gear and begin to accelerate and the noise is present then as well. I seem to think this is that I have to much gear for the speed. This used to happen when I worked for a A/C company while driving a ford f-150 pickup, if I started out in 2nd it would make almost the same exact noise.

I have been trying to find a way to diagnose but all I got was to let the car idle for 15 seconds, turn off put to squirts of oil in each cylinder put the plugs back in and start the car. It should be quieter for about 15 seconds but will eventually will return, and if the oil quieted it down then it is most likely piston slap.
(mechanic my dad knows told me this) have not tried yet.

Any help would be greatly appreciated.

I will try and get a sound bite of it, ASAP.

Thanks
Mike
