youāre running too rich.
what does blue smoke mean?
Thatās what I got some blue smoke. But, it should be okay since itās in the shop right now. Ordering rings and pistons from NOPI so the shop dosenāt try to kill me.
so blue smoke means pistons and rings?
Blue smoke means burning oil, I believe. Which typically comes from worn piston rings. I have heard, however, that if you replace your rings you should also have the cylinders honed. I donāt see why the pistons themselves should need replacing, unless you just want higher compression pistons or something.
Burning oil can also come from the head leaking. Bad valve seals or something. I donāt know much about that. HTH until someone can give you a more definitive answer.

The Bad Newsā¦
I just picked my car up from having the check completed and the guy told me $1700.00 for a new engine. He said that the engine in there with 230K is done but to me the engine purrs like a kitten. It drives like a champ but just has smoke problem. Iām going for a second look tomorrow at another shop.
If you have blue smoke, before doing anything major, like replacing your pistons/rings, make sure to check the head, valve seals, and tubesā¦ You dont want to lay down the $ to replace the Pistons, and then find out that it was only a valve seal leek insteadā¦ Most times (if you drive your car normally) oil leaks are because of worn sealsā¦

How could it be ādoneā if it still runs? Not to mention, runs like a champ and purrs like a kitten. Sounds like itās got a lot more life. I would just get a B16 swap or something. Itāll be cheaper and have more power. And a nearly new transmission to boot. Good luck.

has anyone replaced valve seals with out taking head off?
Thank Godā¦
Problem fixed. Seals. I wouldnāt have thought that but thanks to all you motors heads, I saved a dollar or two. B16A is still being bought but install went down because they want old engine to rebuild. Once again, thanks.

So is there ANY way to tell if itās just the valve seals!??

AMB012977: How was the shop sure that it was just valveseals?
Do you know how they determined that the rings were satisfactory but the valveseals needed replacing??
One way to check your rings is to do a compression test. If your compression numbers are not within 10% of each other pour about a spoon full of oil into the cylinder and try the test again. If your compression goes up then your rings are bad. You can also do a leakdown test but iāve never done them. They are better than a compression test but thats beyond my talents.
If your burning black smoke then your burning too rich. I would do a tune-up and replace the O2 sensor. If you have and adjustable FPR then lower the pressure a little. You could also have a clogged injector.
when your valve seals are gone, typically you burn blue smoke when you LET OFF the throttle. In certain cases, (my car) you burn blue after sitting idle for a decent period of time. ie, warming up in the morning, sitting at a long red light, etc.
But one of the easiest ways to tell is upon deceleration you burn blue.
Rings on the other hand burn blue when you boot it.
