Engine question on piston rings for a 93-97...

^up, 4A-FE gurus out there, need your advise...

question on piston rings for a 93-97...

what are the symptoms for piston rings and valve seal replacement? my mechanic advised me to have my piston rings changed because my exhaust occassionally emits white smog... pls advise...

How many miles?

What do you mean by "my exhaust occassionally emits white smog"? Does this happen just when you start up? If it's white, then that's water... possible head gasket problem. If the rings were gone you would be getting blue smoke.

nah, i'm not getting the blue smog, but the white one, yes... my mechnic told me that my engine is already eating up oil, is that one symptom too?

The blueish smoke is easily confused with white, are you having to put oil in all the time? It would puff a big plume of smoke at start up if the rings were completely shot. Sounds like the problem might be valve guides or gaskets or both if you are burning some oil sometimes. Here's a little info for everyone who might wonder;

White smoke = Coolant/water
Blueish white smoke = Oil
Black smoke = Fuel(running rich)

i might hafta change an oil seal or something

Is that a question?

man, i'm also confused right now, haven't had much time to visit a service center... i was initially advised to have my oil seal changed... my ride has 150K kilomters on its mileage...

blue smoke is the sign of leaky oil but i dun think white smoke hav to do w/ oil... must be something hav to do w/ your cooling system...

turbo your ride, and the smoke will disappear. It works!
