Car Forum / Toyota / Camry / November 200998 Camry 4-cyl / Puff of Blue Smoke after not running for two days???
Hello to anyone left here - NOT TO SPAMMERS THOUGH! I have a 98 Camry with 126000 miles and today when I started it, I noticed a puff of blue smoke came out of the tailpipe. I know it's oil smoke but is there anything I can do avoid problems - different oil, additives, whatever. I use standard 10W30 oil and change it every 3000 religiously, just had the timing belt replaced last month, had it checked for sludge - which the mechanic says is fine. It runs great otherwise. Any suggestions or comments? Thanx, Kaz > Hello to anyone left here - NOT TO SPAMMERS THOUGH! > [quoted text clipped - 8 lines] > Thanx, > Kaz My 99 does this too. I believe it's the valve stem seals. My understanding is that these cars will act in this way. My mechanic is familiar with this problem and told me to just live with it rather than fix it. In his opinion, it ain't worth the trouble. "dsi1" <dsi1@spamnet.com> wrote in message news:7TpHm.41696\ > My 99 does this too. I believe it's the valve stem seals.

But, after you get started up, often the oil loss is not so great. You could try a high mileage oil. They no longer have the aromatics which swell seals. The new technology is polymers which do not damage the elastomers (any more than they are already damaged). This is not such an expensive job if you DIY. BUT, you need to be clever with your hands, and you need to know some basics to do the job...like how to keep the valves from falling into the cylinders when you remove the keepers. (It isnt a hard trick to learn.) > "dsi1" <d...@spamnet.com> wrote in message news:7TpHm.41696\ > [quoted text clipped - 16 lines] > how to keep the valves from falling into the cylinders when you remove the > keepers. (It isnt a hard trick to learn.) They say 50% of engine wear is on startup, so that puff of smoke should make these motors last 500,000 miles, it lubes, when you need it most, at start up. I say leave it alone my plugs burn clean. > "dsi1" <dsi1@spamnet.com> wrote in message news:7TpHm.41696\ > [quoted text clipped - 16 lines] > how to keep the valves from falling into the cylinders when you remove the > keepers. (It isnt a hard trick to learn.) This would involve getting a spark plug adapter to attach to your compressor. :-) >> This is not such an expensive job if you DIY.

In many engines you can just raise the piston to TDC and that will prevent the valve from falling...or you can feed a small diameter rope or a heavy cord through the spark plug hole to fill up the space on top of the piston. You can beat the ceramic out of an old spark plug, thread the bore, and make your own adaptor. What you really DO need, IMO, is a decent valve spring compressor. > Hello to anyone left here - NOT TO SPAMMERS THOUGH! > [quoted text clipped - 8 lines] > Thanx, > Kaz Maybe try an oil filter with an anti-drainback valve, if you aren't already? How come 10W-30 instead of the recommended 5W-30, just curious? Michael > Hello to anyone left here - NOT TO SPAMMERS THOUGH! > [quoted text clipped - 8 lines] > Thanx, > Kaz If it only does it briefly, after sitting for a couple of days, don't worry about it. If you can't not worry about it, you can try a 'high mileage' (odometer, not fuel economy) oil, which will swell the seals slightly. I wouldn't do that, though, unless it starts to burn oil while on the highway. > Hello to anyone left here - NOT TO SPAMMERS THOUGH! > [quoted text clipped - 8 lines] > Thanx, > Kaz Its probably the valve stem seals are a little worn. I wouldnt worry about it as once the engine warms up the seals will expand and prevent any burnoff. If it starts to burn oil continuously (which I doubt will happen considering your oil change intervals) I would try some sort of seal softener that can be added to the oil. this will soften the seals and allow them to prevent burnoff. Its an expensive proposition labour wise to replace the seals if you want to go that way.? I would listen to your mechanic. > Hello to anyone left here - NOT TO SPAMMERS THOUGH! > [quoted text clipped - 8 lines] > Thanx, > Kaz If you dont consume much oil dont worry, 1 qt in 3000miles is what I do and mine smoked for 10 years |
