Full Size Blazer Burning Oil!!!

White smoke coming from the exhaust....

I run my finger around the exhaust and it looks like I stuck my finger in pure oil

Then my needle volleys sometimes....

What might this be? I was reading a book and it said something about the pistons or oil is getting past some chamber thing? I don't know! Confused

What can I do to get it to stop smoking?

93 Blazer (FULL SIZE-LIKE TAHOE/YUKON/ETC.)

180,000 Miles

Also, is this expensive? Do they have to go in the engine or so?

I would suggest that you take your vehicle to a reputable mechanic for further diagnoisis.

Difficult to tell here, but your comment regarding using your finger around the exhaust and oil "could" indicate that you are infact burning oil within your engine. But would best be viewed and assessed by a local mechanic of your choosing.

As you suggested in your reading, oil may be slipping past the piston rings and entering the upper portion above the pistons i.e. "combustion chamber"...hence as the motor burns fuel it would also be buring some residue of oil, hence the smoke out the exhaust.

The lower part of the motor contains mostly moving parts and a pan of oil, the upper part contains an area where the fuel is mixed with air, burned and exhausted out through the exhaust pipe.

The two areas are separated by a series of rings which fit around the pistons. Over the course of time, and 180,000 miles these rings CAN eventually get thinner, sort of sloppy in their space and allow small amounts of oil to gain entrance into the combusion fuel burning area....

Far as expense goes....suggest getting a few diagnosis and repair prices and report back ...I am sure this forum would help you determine the next course of action...

Hope this helps....

Thanks a lot! You are a genious! A few people have been telling me this is what may be happening! I really appreciate it. They would have to lift the engine correct???!!! I hope not..........Please tell me no!Cause I know that will be expensive! Do you know about how much this may run? Thank you Great day!

Thanks for the kind words....been called alot on this forum and "genious" isn't one of them :iceslolan

Chances are good that yes, they would pull the motor....if that'd be the case there ARE alternatives , i.e. a rebuilt motor, salvage yard motor with lessor miles on it would / could be cheaper than paying a local mechanic to do this for you....

But before you do anything , get a professional opinion from some one you trust as to what it would take to fix your existing motor, balance that between a "used" newer motor, and/or maybe even replacing the vehicle.

I hate to steer you firmly in any direction, cause I just don't have enough information...so I am offering just an opinion.

But don't give-up-the-ship until you have a clear reading of your trucks condition.

Thanks a billion Tony! Yes,a genious is as a genious does! How did you get the smileys as well? I was seaching for em! Thank you. I will take it to the shop! Dang, I was hopin to not pay much!

What this about the VALVE COVERS or VALVE SEALS or something someone was telling me....Does this affect the exhaust? I see a bit of oil on top of the place or around the place where I pour oil as if the engine needs to be degreased, it's not fresh it's a bit of build up there. Thanks a billion

Just a few more questions...

1) Exactly how much oil do you go through?

2) Does it do it more at start-up or does it matter?

3) Have you compression tested the cylinders?

The valve covers leaking would not put oil in your exhaust. Valve seals will allow oil to leak into the cylinder, but it is usually only noticible at start-up.

PCV valve could clear this up.

White smoke during warm up or running on a cold day is normal.

Blue smoke means an oil problem.

Also, what do you mean by you finger looks like it was dipped in oil?
