So, I have blue smoke.

I have bluish smoke coming out of my exhaust. Sometimes its really bad, sometimes it's not. I cant really say when it's worse. Anyway, what are things I can check to verify this is what it is? That is, if it isn't my piston rings, what could it be? Or is the piston rings?

I have almost 250k

I thought only turbo cars had problems with blue smoke

Uh, no.

It might be the valve guides, how do the spark plugs look?

I havent looked at them-- I tried once and I couldnt get it out.

i say when it happens again you should run away

I dont know the way to take them out, excecpt maybe getting some penatrating oil and get a put some kind of cheater pipe to increase your leverage. I just use my torque wrench cuz they got plenty of leverage. Just gotta make sure it dosent break aprt your plugs, its just not the end of the world if it breaks.

Alright. Anyway, what about the spark plug? If its coated with oil and crap, it means..

If it's clean, it means...

Oil might be passing through the rings into the combustion chamber and/or the guides. A normal one ( i think) is usaully white with normall wear on the tips of the plugs, or deposits in and around the plug.

hey ghetto u gotta check your plugs (they'll tell u alot whats going on in your engine), have u ever gave it a tune up? if u cant take off the plugs try using a breaker bar at the end or your rachet!!!

if you have blue smoke comming out all the time it is your valve seals. easy to replace.
if you have blue smoke in the morning when engine is cold, but it stops smoking when it gets hot. it is your vavle guides. very hard to replace.

Wow now your ride is really ghetto :rice:

I keep my engine in as good of condition as possible. All maintenence is up to date, however the previous owner didn't keep it up to date. It was ghetto when I got it, but now, other than the engine, it is clean and in as pristine condition as possible. I don't see why people dont take care of their cars. Even if you dont have money, changing the oil probably would have pushed this condition out a while. But I can't go back in time, the damage is done. I will check my spark plugs if I can get them out. As for the smoke coming out, I've noticied it mostly when cold, but occasionally I think it happens when warm. I could be wrong on this. Aside from the fact, the engine still runs very strong. It's got so much pickup and speed. I did notice on Saturday that when I had 3 people in the car, it was really sluggish.

mine does the same thing. i did a leak down test and checked my plugs and have determined that my rings are good so i guess my problem is in the head. since i need a transmission, carburetor, and possibly a head gasket as well as head work i have decided to just replace my engine and tranny with a good used one out of an 89 dx that i just bought for 225 dollars. it is smashed in the front but is repairable. other than that it is flawless. if it had a title id just fix that one. but if you need any parts from that car or my old engine let me know. the dx is perfect from the doors back.

I just finished checking the spark plugs. All four are clean as a whistle. What now? What should I do?

compression test

Done, all 4 working up to par. I have the specs if you need it.

have you noticed any slight lose of brake fluid?

my sisters plugs were so old they were rusted on the threads and when I measured the gap it was like.076

No loss of brake fluid. My plugs are new. Well, in July they were replaced. They are clean.

By the way, the compression test was done in November. Here are the specs:

Cyl 1: Low 5.3, Firing KV 6.6, High 7.0
Cyl 2: 5.1, 5.9, 6.8
Cyl 3: 5.2, 6.1, 6.7
Cyl 4: 4.0, 6.2, 6.6

I was looking through my paperwork for it, and the oil leak is from the "front cover area- not enough to be concerned with."

hey ghetto how does your oil look? does it look watery?

How should I diagnose that? Dipstick? I dont do oil changes now since its only about 14 bucks to get it done by someone else.

yea u can use the dipstick, pull it out and inspect it, put some on your hand, even smell it.. u might have a blown headgasket, or a hair line crack in your head and its leaking antifreeze into your engine, so your oil will tell u alot..

also check your radiator level, has it droped?
