Car engine oil has water...Question.......

[cornbread]

84 Chevy Blazer.. Still running good, noticed water in the oil.. Got an oil change, and the water has come back. The antifreeze in the radiator still looks fine and isn't going down or needing refilling.
Would this still be a head/head gasket, or could this be something else?
The engine has not overheated before that we know of..

TIA for any possible clues!!

 

Several possiblities ;

(1)Blown Head Gasket
(2)Cracked Cylinder Head
(3)Cracked Block
(4)Blown Intake Gasket

It takes very little Antifreeze to make the oil into chocolate milk, watch the coolant level very closely.

ditto what roger said.

Just finished fixing an audi with this problem.

It had cracks in the head, between the valves. When I was looking for a replacement head, I found another with this problem. Must have been a problem on the '84's.

This is exactly what I was gonna say. Roger knows what he's doing, he's in the business.

Could be the oil pan gasket.....

I have always called it "baby sh!t"

Cornbread: Lemme guess. This is the s-10 version and you have the 2.8L engine?

What, did it turn into a water generator or something?

Right, only if you are driving in four feet of water all the time.
Can you please explain to me why a leaking oil pan gasket would allow water to enter the oil.

He drove into a lake. Duh!

LOL...You are correct.

Thanks you guys for the quick responses

 

Evadman, I did not want to scare him, that is why I did not reveal the lifter bore cracking problem on these engines.

In that case, I'm gonig to say that I think the air filter is leaking.

For some reason, that is the best one liner I have heard all day

I spun a bearing in mine, right at 80,000 miles. I think the engines have a timer that sets the engine to self destruct at 80k. It is an overall crappy engine IMHO.

Cornbread: Instead of putting any money into that engine, I would suggest a 4.3 or 350 swap. The 2.8 = suck. Both the 4.3 and 350 swap will require a new trans. the 350 swap has been done for a long time, and is well documented out there. The biggest problem is squeezing the exaust around the steering shaft. I have seen block hugger headers, and s-10 only headers that wrap around the steering shaft. IMO, it would be better to spend 2k on a 350 swap then $1200 on a remanufactured 2.8.

Or you could just hope it is the head gasket and change it yourself.

I had that happen once on a Gremlin. The oil pan gasket had rotted or just came apart and there was about a half inch gap in it. Yes, it leaked oil bad too. Put a new gasket on and everything was ok, for a Gremlin anyway.

Damn, you sure make that sound easy. Have you ever attempted anything like this? It's not like swapping out a processor or something.

He can also probably pick up a used long block from a salvage yard with a warranty for about $500 or so. It'll still be a DIY job, but he won't have to worry about swapping tranny's, motor mount headaches, radiators, exhaust, p/s, fuel lines, a/c brackets, etc. This is not a job for an amateur.

Actually, yes. In high school I put a 350 into my s-15 jimmy.

After your advice to the guy who's Tbird was wrecked, I think you talk more than you know. See here

About collision, yes

What did you do about the engine computer & differences in the wiring harness? You can't just splice in new connectors, it changes the resistance, which is a big problem in engine computer components. Most of them read by reading resistance, for instance, an Oxygen sensor. If you just eliminated all the emission control stuff, you're violating several state and federal laws.

Keep in mind, this was in '96, but I will try to remember as best I can The engine was a kit from PAW. Std 350 with 2 bolt mains. Yada yada. The trans, wiring harness, computer, injection ( 2 bbl ) was from a k5 blazer. We just used the sensors from the K5 for the most part. Why would I use the computer or wiring harness from the 2.8? It would be just about impossable.

.5" gap? That's a big gap for a pan gasket to leave. Sounds like the oil pan was falling off.

 

[Bluefront]

Change the oil and trade it in somewhere. A low-milage junk-yard engine would be the only other practical choice....

 

[Evadman]

An oxygen sensor produces voltage, not changes resistance. Most other sensors read restance like Map, Temp, Mass air, ect. the o2 does not.

<edit>
ok, it actually adds and subtracts voltage from a reference signal sent by the ECM, but you get the idea.
