In my 93 del sol si..a lot of smoke(burnin oil im guessin from the blackness above my exhaust) is comin from the exhaust..what could this mean?..thanks

AHHVTEC

what color is the smoke

ghsbaseball91

the smoke is white

YBLEGAL

white = coolant
black = rich fuel mixture

AHHVTEC

yea what he said ^^ and blue =oil burning

ghsbaseball91

so does that explain the black right above my exhaust on my bumper? and does that mean im leakin coolant or what?

YBLEGAL

it's possible your running rich AND burning coolant. the next thing i would do is a compression test.

AHHVTEC

if the smoke is real white and stays that way, there is coolant getting in the motor somewhere

Time for a compression and leak down test.

i have no idea what u mean by runnin rich, and what is a compression and leak down test?

norcalgsr

They are tests to determine the condition of your engine. I would recommend you take your car to a shop and have those tests done as there is definitely a problem with your engine, and with your limited knowledge doing the tests yourself would probably not be a good idea.

Usually when you have white smoke coming from the exhaust it is caused by a blown head gasket, warped head, or a cracked head or block. The only way to know for sure is to have those tests performed on your engine.

and running rich means that your car is putting too much fuel into the engine.

ghsbaseball91

how much do those tests usually cost?

YBLEGAL

they're not too difficult. i would expect $10-30 depending on the mechanic. Most local mechs do a diagnosis for 20 bucks around here.

ghsbaseball91

thats not bad..i was expectin a lot, what all will those tests be able to tell from my engine, not just where the smokes from?

norcalgsr

They will basically tell you if anything inside your engine (piston rings, valve seats, head, block) is damaged and where it is damaged. It will most likely explain the cause of the smoke, and determine what you need to do to repair it.

Hey this has been very helpful to me guys, thanks much. Sadly i'm burning oil....it's blueish smoke but only when i first start my car an when i take off from a stop....what could that be??

norcalgsr

Probably leaking valve stem seals, worn piston rings, or a combination of both.

thanks much. I'll have one of the mechanics figure out if he can fix that tomorrow or sometime this week. =]

norcalgsr

It won't be a cheap fix if that's the problem.. start with a compression & leak down test and see what the results are.

ReDCiViCSi

alright, what is your opinion on just taking off the head an doing a minime swap? an getting that stuff looked over an replaced at the same time? or should i just work on getting a new engine... i work at an autobody shop so i can get the labor done cheaper...an do some myself.. what would you do?

norcalgsr

If your block is still in good shape the mini-me would be a good idea. I would probably pull the engine and have the block inspected to see what kind of condition everything is in. If the cylinders and crank are still within spec you can replace the rod/main bearings and piston rings and have a near new block. On the other hand if you need to bore the cylinders or replace the crank it might be a better idea to start searching for a new engine since the D series are pretty cheap in comparison to a full rebuild.

I would start a new thread if you have anymore questions too.. so you're not taking over the original poster's question.
