blowing white smoke out of exhaust

Featured Replies

I was wondering if someone could help me out.

I'm not a mechanic, but I think my 87 sub GL10 is in big trouble.

Getting to the point. I started it up this morning and just a tone of white smoke started blowing out the tail pipe. It ran idle for about two minutes this way. I was hoping it would stop on it's own, but it just got worse.

I shut it off and checked the coolant and it was low. Then checked the oil dip stick and I could see water mixed with the oil, and the oil was very light milky colored.

 

 

Any chance of some good news coming out of this? Sounds like a cracked block I guess, but like i said, i'm no mechanic.

Thanks much!

Some turbo heads are prone to cracking but it most probably due to bad head gaskets. Coolent in the oil and white smoke are normally due to a blown headgasket/s. Has it been over heated much? Might also be seals in turbo if its oil and water cooled but i dont know turbos.

 

To do headgaskets you need to pull the motor.

It probably aint a cracked block but head gaskets are quite labour intensive. But if you could do it yourself...

Thanks for the reply.

 

No way I'm doing it myself...

 

Anyone mechanically inclined in the Seattle area want to come help me out?

 

Kidding.... sort of

 

About how much would it be to replace the gaskets?

It's been a great car up til now with great power and unbelievable turn radius. It's a turbo 4x4 - fully loaded. Body and interior are both in very good condition. I hate to junk it.

Try it yourself. I just did it on my 89 GL 10 about 2 months ago. I replaced both heads and head gaskets in the car. Man it was a pain in the butt too! Next time I think I would pull the engine to do the job a little quicker. But it was a good learning experience.

I don't know about that. What kind of special tools would I need? What manual would be the best to use?

It's one of two things. Either it's a cracked head or it's a blown headgasket, both require you to pull the engine. Cracked heads aren't as common as blown headgaskets to the best of my knowledge, but I'm pretty sure either way it'll be somewhat of a pain in the butt.

Do you absolutly have to pull the engine to do heads? As in, no way around it?

I have done 4 HG's now (both sides on both subies), both on N/A and Turbo, and I have never pulled an engine from either of my cars.

 

Of course it is easier access if you pull the motor, but you no not have to pull it to change out HG's.
