Valve guide seals? - This much smoke? #4104780 05/23/16 09:12 PM

On my Camry, it smokes (blue) on startup about 3/4 of the time I start it up. Usually in the morning, sometimes after its sat for like 4 hours in the afternoon. Today I started it after I was out of town (in another car) and it sat for 4 days. I let it run for 4-5 minutes to let the A/C cool the car and it had a constant blue smoke plume coming out, it gradually died down after 4-5 minutes. Is this the valve guide seals? It runs great, and actually burns a quart every 3-5k miles. Been 1,500-2,000 miles since I topped it off and it was 1/2 way between the add and full line on the dipstick, so 1/2 quart. New PCV valve last year, no sludge, very clean under the valve cover.

From 195k-200k I ran Chevron Supreme HM 5w30.
From 200k-205k I ran Pennzoil HM 5w30.
From 205k-211,400 (current) it has Pennzoil Platinum HM 5w30, going to change at 212,500.

So, valve guide seals, or something else? The smoking and burning actually doesn't bother me, but if it's something I can fix without rebuilding the engine I'd like to give it a try. Don't really care for additives.

valve guides for sure. If it smokes on hard deceleration its most likely rings. a valve job on that car would be super easy and inexpensive. are you able to take the head off yourself?

I've never noticed smoking while driving.

I could probably do it myself. Just depends if it's worth it. If adding some oil is all it needs I'll just do that. If it's hurting anything, I'll consider a proper fix if valve guide seals are the issue.

There's nothing more whimsical than firing 'ol Betsy off and having her disappear into a cloud of smoke on warm up. Drove a '70 6 cylinder Camaro for 9 years and that's the way it was every day after work. About 2 miles down the road she'd finally clear off and the show was over. Consumption was around a gallon a week but she always ran well.....

I don't think any oil choice will help unfortunatly. if you drive highway speeds and safely downshift the trans and watch your rearview mirror with no throttle at all for a couple seconds then push the throttle and keep your speed you should not see any smoke. With the harsh vacuum created the piston would pull oil up and burn it with bad rings. I'm pretty sure its the guides though.

Yes I forgot about that. In it's maintenance history on the Toyota Owner's website it shows they were replaced at like 83k miles.

I'll try to get it on video tomorrow morning, it chugs out a good amount but it isn't blinding. You can see through the clouds, not so thick that it's not visible through it.

What happens when you redline the engine? Is there smoke?

If there is it's probably not the seals.

I thought the hallmark sign of bad valve seals was if you sat at a red light for a few minutes, you would get a puff of blue smoke when you pulled away but that would be the end of it.

Either way, it doesn't take a lot of oil to make a lot of smoke, so I would just top it off.

probably not the seals, had the same thing happened to me after I change my muffler from a straight type to a S type, I thought it was the valves seals, but after I change them the issue persists. So its gotta be the exhaust collecting a lot of condensation. Besides , I notice very little (100ml) oil loss at 8000km .
