Re: Cleaning your engine of evil carbon

Top Engine Clearner: update
I performed the TEC carbon cleaning last night. With the engine idling, I sprayed it in the PCV hose... unplugging the vacuum hose made the car start to run rough.

I sprayed about 90% of the bottle in, and then thecar stalled when I plugged the hose back in.

Turned the car back on, and raised RPMs to ~2000 until the white smoke began to come out.

This morning I cranked her up, and raised RPMs to 2000 and so much white smoke kept coming out forever, and ever. I think I may have startled other neighbors--some lady got on her cell phone, or maybe she was already on it.

Easily a cloud the size of two 3 story buildings. Wow.

I then went for a brief drive to the dealership with a coupon for a $22 oil change. On my way I put it in 2nd and raised it near redline, then let the engine slow down. I did this twice--and no smoke or anything came out.

I got my oil change, then repeated the 2nd gear to redline, and engine braking down to 30 on my way in to the office.

Clean as a whistle.

The engine sounds crisper, more mechanical--top of the engine still has ticking sounds which are likely normal valve/cam sounds.
