For full features; Go to Daewoo water in oil
Ok I bought the car from my son-in-law. (Never did like the kid, but you
know how wives are.)
The car is a 2000 Daewoo Leganza. At sixty thousand the car developed an
oil leak near the water pump on the engine. The dealer repaired it and I
had him install a new timing belt at the same time. At seventy thousand
the car suddenly started blowing oil and water out of the surge tank. Ok
warranty is out so I’ll change the head gasket myself, no big deal. Off
comes the head, hum the gasket looks good. Head goes to shop for pressure
testing and new valve job. Head is in great shape valves are re-faced and
lapped in, head sheaved .004 to insure flatness, cams ok, found one bad
HLA, replaced. Checked block found no cracks, minimal lip on cylinders,
cyl walls smooth no scratches, etc. Everything looks good. Head goes back
on (and all the time this little nagging voice in the back of my thick head
keeps saying something else is wrong and it won’t shut up). Installed the
head, found a bad bearing on the snake belt Idler pulley. Fixed that.
Filled engine with oil and water, Ran compression check on all cylinders,
check ok. Disconnected coil plug and cranked engine for thirty seconds to
oil cams and hla’s, and then says to myself, gee I didn’t put white oil in
this engine. Checked oil and found three times as much oil then there was
supposed to be. Whoops! Can’t be a bad block. Can it? This is a big
leak. An awful lot of water was transferred in a total of maybe 40 seconds
cranking time.
The car is 2000 Daewoo Leganza with 2.2L DOHC 16 Valve D-TEC. This is a
Holden engine from Australia, The engine is used in several Gm cars (a
Buick I think) , and the 2000 Rodeo and Amigo. I have tried searching the
web for knowledge of Holden engines with no luck.
They must have an agreement to keep their mouths shut for some reason.
Daewoo has little support here in the US. Europe seems to have more
support. Tried to find TSB’s with no luck. I have the Daewoo service
manuals, six inches thick and no clue.
My question, Has anyone seen this? Is there a weak spot between the water
pump and oil pump which would account for this problem? This thing has a
cast iron block and I still have trouble believing the block cracked.
Foolish me! Engine has never been overheated and has been serviced on
time.
My next step is to pull the pumps and check them out. At this point it
might be better to pull the engine then try to fix it in the car. What do
ya think?
Tanks for the help in advance,
Daewooless John

From everything you have stated, it does seem that you have a major leak
somewhere between the cooling system and the crankcase. You said that
coolant is getting into the crankcase and mixing with the oil.....is there
any coolant getting into the cylinders themselves? I would presume not due
to you not mentioning any type of hydro-lock or anything from the cranking.
Have you pressure tested the cooling system and attempted to see where the
coolant is getting into the block? You could pull off the oil pan and then
pressure test the cooling system and while underneath, look to see where,
up in the engine, the coolant is getting in. You may have to run dye in it
too. If the leak is that large, it should not be that horrible to
determine where it might be getting in. You might have a cracked block
too, definite possibility for a leak that harsh.
When they started playing the Daewoo commercials here in Virginia on the
radio, I thought it was a joke. I would never own one but hey, I never
have so I can't really judge them other than from the assumption that they
are not too popular around here.
I would make certain the head job you did is bullet proof and that the
gasket is solid and then start exploring other options. Is there any
leaking of coolant exteriorly such that it pools on the ground or is it
just mixing with the engine oil for the most part internally?

Thanks for the repley cmeseadoin.
No water in the cyl.
No water on the ground.
Head tested and repaired by some of the best in the business, is there any
other way? :)
Coolant system will not hold pressure.
I have not pulled the pan.
The oil pump is not in the oil pan, but mounted on the block arround the
nose of the crank. Something new to me. The water pump is just above that
and driven by the timing belt. They're so close together I though there
might be a shared gasket.
I really love this car. It handles well, will cruise at 80 all day. The
engine is filled with gm parts, and the car is fully loaded with all the
acc's. The stereo is Bose six speaker. All the goodies. I liked it the
moment I drove it. I had a 1998 Lexus, but I think this is a better car.
The car was designed by Mercedes, The 2000 Mecedes 430 is identical except
fot the badges.
jcutsh
Hmm, you might then want to pull that water pump out again and have another
look. Are you sure that if you had this apart before that you did not
forget to install some bolt in there that closes off a hole in the block or
something? I really can't think offhand of anything else. :banghead: It
sounds like a MAJOR leak and that is why I wonder if something internal is
missing or worse yet, if you have a block crack? :doh: You might still
wanna pull the oil pan and pressurize the system first to see if you can
see where it is leaking into the crankcase. Perhaps if the water pump is
on the lower front of the engine you can see that from the inside of the
crankcase with the pan off?? Just a suggestion.
cmeseadoin
Uhmmm...there's a huge reason the Daewoo has neither the recognition nor
the reputation of a Mercedes or Lexus.
Here's one: http://www.carcrashtest.com/news_releases/2000/pr041100.htm
There's a saying that goes something like...
"You get what you pay for."
When comparing the Daewoo to a Mercedes and/or a Lexus...that certainly
holds true.
But...you like it and that's what's important.

One question.Does the water pump and housing serve as the timing chain
cover also???????
lectroid
Only thing that comes to my mind to keep it simple is water is leaking out
of the head bolts and into the holes drilled into the head for the oil from
the valves to drain back into the oil pan. You should have put sealant on
the head bolts before re-installing them. Assuming they cut into the water
jackets along the cylinder walls. Pop off your valve cover, fill with
coolant and crank. Get back to us..
HTH.. :thumbs:
It's not a Ford dude :laughing:
DodgeRida67
this may sound like a stupid question but i just want to make sure
You do use coolant/water 50 50 not just water right?
water along wont keep your car from overheating especially when cruising at
80
and whether that's the case or not it sure as hell sounds like a cracked
block to me
he sounds liike he's done a few head gaskets before quit harassing about
his install harass him bout the other weird things he's said like I am
doing

sad reality is that the head will more than likely have to come off again
to look internally. You've either got something very simple yet hard to
find going on, or you have a major engine problem, ie) cracked block.
You've got coolant getting into the oil and therefore the cooling system is
open somewhere.....you sould like you know what you are doing so get
diagnosing it. Start at point A and work down the list. I think we've all
given you some good information so it is up to you now to fix it or R/R
it.
Yes I agree with Bav on the Daewoo theory and stick to mine.....I would not
touch one with a ten foot pole. Yes the Leganza has buttons and gadgets
but it's a Daewoo. Hell, common sense tells me that if it does not have the
reputation that other automakers have, has not been built for as long, and
does not have raving reviews then it is best to avoid it. They may be good
cars, I don't know, BUT I don't want one. That is what makes the world
interesting though, people have different opinions and attitudes even
though I'll be damned if I can understand some of them :laughing: !!!
Hell, any automaker called Daewoo surely can't have much sense, LOL. I'd
be embarrasses to tell my friends I drove a "Daewoo." :hi: NO offense
jcutsh! ;-) all in good fun.
cmeseadoin
DUH! can you answer my question? :ticking:
lectroid
Thanks pieface, There are no stupid questions, only stupid answers. The
timimg belt was changed by the dealer only 10k ago so all the fluids were
new.
jcutsh
is there a heat exhanger on the car?
cinqyg
Great Idea Wally, I have tried to find all the Aussie forums, but so far
none that I have found have any troubleshooting threads on them.
The car was put together with a new GM cyl head gasket set, and new head
gasket. I'm to old to do things twice.
Yes Cold crank produced almost two gallons of water in the oil, in only
about 40 sec.
Yes holes were cleaned with stodard solvent (mineral spirits) It has been
80/90 degrees here. there was no water in the block during installation.
jcutsh
No the water pump sets in the block, about a five inch hole. the oil pump
is located on the front of the block arround the nose of the crank.

Ya know, I came on this website looking for a little help from what I
considered some very knowledgeable people. If I had wanted to be beaten
up, I would have jumped on my bicycle , road down to the local truck stop
and had someone beat me with a tire bat. I bought the car because My
son-in-law did a stupid thing and caused hardship on my daughter. Most
fathers would do that sort of thing. I never said it was the greatest car,
just that I licked it. However, Only a few were sold, they are
disappearing everyday. The price is dropping like a rock. IMHO I think
the car will be a great collector. Remember the Edsel? People buy cars
for different reasons. Just because you don't like them is not a reason to
judge their intelligence.
I changed my first head gasket in 1956, at age 15. It was on a 1951 Nash
Ambassador. I made the head gasket from a shoe box. I didn't know a
gasket only cost $1.35. The car ran for a week on the shoe box gasket.
Then I had to fix it again.
I have learned a lot since then, but I didn't really start getting until I
turned about 50.
I will fix this car, and then put in in the back of my garage with the
others and someday I or one of my children will sell it, hopefully at a
nice profit.
Oh, incase your worried about my safety, the car was recalled in 2001, and
the Mercedes bracing (Daewoo decided to leave out) was installed.
jcutsh
Sorry for coming off strong...didn't mean it that way.

Maybe now we've, got that Alpha male stuff out of the way, you and I will
be great friends. I Apologize also :)
(Don't ever ask what I think about Fords!) He-He_

Now that we have that Alpha male thing out of the way, I think you and I
will become good friends. I apoligize also.
BTW, I love BMW.
Don't ever try ask me what I think about Ford. he-he
(second time I have tried to post this)

Sorry about the guys. :mrgreen: We all mean good, we really do.
So how about what I suggested, try it yet?

Ok all,
Obviously this is a problem no one has seen, and there doesn’t seem to be a
regular fault with this engine. So I have a ‘one of a kind problems’. I
dropped a dime, well a couple of dimes, to Holden and they are as mystified
as we are. They said they had never had a block failure and would help pay
the cost, if I would write a report about what I found. Now that’s a
company who is worried about its rep. I am pulling the engine for a full
inspection.
I’ll let you guys know what I find out.
Thanks everyone for all the help. I enjoyed all the efforts by
everyone.
Thanks again
John
Keep in touch :)

Now that is AWESOME!!

our mechanic friend suggested pullthe oil sending unit out and air pressure
it up from the and see if you can see where the air is leaking from.
rayray0071963
I think the problem was resolved sometime throughout the last two years
lol.
chris_knows
I think the car's probsbly dead now, lol

Rayray to the rescue!
