Initially, I had a problem with my engine smoking at idle. The smoke would go away once the engine was revved (worn out valve stem seals). During the cleaning stage, the problem didn't completely disappear, although it didn't happen as frequently as it used to...almost seemed as though the problem went away. I followed the heavy oil burning application, and changed my oil/filter after 2,700 miles (drove an additional 700 miles, as I was pretty busy).
After the oil change, I noticed the smoking problem returned to its previous state as far as frequency is concerned. 300 miles into the rinse stage I had to change oil again, however, due to a leak. The oil drain bolt's thread pattern wore out and was leaking oil as a result. Afterwards, the smoking problem completely disappeared with no trace whatsoever.
Today, my engine started smoking like a freight train - even when revved. Clouds of smoke would continually puff out the exhaust. When I returned home and parked my vehicle, there was no sign of oil burning again and I let the car idle for a couple of minutes. I haven't had the opportunity to check oil level just yet, as it is dark...but I'd like to find out if this is normal. I remember reading that everything happens during the rinse stage, so I thought I'd ask. Thanks a lot!
Falcon, what kind of vehicle is this and how many miles do you have on it, I would also recommend that if you have not done so to change your PCV, and to also check the PCV hose if you have one. It may take a little time for the smoking to go away, have you checked your spark plugs, keep us posted. Brent
Many thanks for your quick response. The vehicle's a '00 Mitsubishi Pajero/Montero with 135,450 miles on the clock. The PCV valve was replaced at the 132,000 mile mark, along with the spark plugs, water pump, head gaskets and timing belt. The PCV hose hasn't been replaced though...should I go ahead and replace that as well? Thanks a lot!
Many times alot of contamination is released during the rinse phase. Contaminants could be releasing from the stems and guides and entering the combustion chamber depending on the valve position while the car is shut down. This will subside.
Sounds like it's time for a catch can. See what's coming thru the PCV valve. I didn't get any help from ARX with my acceleration after idling smoke in 2 arx cycles. The PCV catch can didn't show much either. THought there would be alot more oil in the catch can with the amount of oil I was burning through.
