3:00 pm One day truck started right up but with a little hesitation when the engine tried to turn over.

10:00 am. Vehicle started right up but with smoke. 10 minutes past. No more white smoke while driving.

10:20 am. Park car.

10:30 Started vehicle and white smoke came out. 10 minutes past. No more white smoke while driving.

11:00 am. park vehicle over night.

06:00 am. Vehicle hard to start. Starter motor tried to turn over the engine but it can't. It took 5 tries to get it started. White smoke comes out and white smoke went away after 10 minutes driving.

06:30 am. Park vehicle.

03:00 pm. Started vehicle. Hard to start, engine won't turn over. It takes 2 tries to get it running. White smoke comes out and white smoke goes away after 10 minutes.

04:00 pm. Park vehicle.

05:00 pm. Check for code. It showed. P0138 error. 02 sensor circuit high voltage (Bank 1 Sensor 2).

05:30 pm. Checked 02 sensor for wire problem. No loose wire and no scraped wires on 02 sensor. Replaced 8 spark plugs. 1, 2, 3, 4, 5, 6, 8 spark plugs have a little white powder. #7 spark plug was dark and smell heavy gas (no white powder). Replaced all 8 spark plugs. Started vehicle and still have white smoke.

06:00 am. Started vehicle. It took 3 tries to get the vehicle started.

I have already check for the 02 sensor price. However, I will check and replace my Distributor cap and rotor first and test it.

If not, my next step would be to replace the 02 sensor.

Next step would be to replace the crank shaft sensor.

Any idea what I need to do aside from the steps that I will be doing? Thanks.

I would do a compression check before I threw any parts at it.

Sounds like valve guides, check spark plugs for heavy carbon formations.
Airjer said something about the pcv valve once I think.

Yup, he did,

i would pull a plug or two and see if there wet with antifrezze? and yes do a compression test.
