coolant in oil

[AG 305]

i just checked my oil and it was all milky. checked my oil cap and also milky oil under it. im already suspecting a bad HG/cracked head but i wouldnt want to! ive driven the car before with absolutely no loss in power or anything of that nature. idles fine. no leaks that i can see

how many other possible things are there that can cause coolant in the oil??

bad VC breather/PVC set up? turbo? oil filter housing? water pump? IDK

car right now has a new 16psi rad cap, new thermostat (cooler then stock) ac/heater out, 14b with minimal shaft play.

if its a HG/cracked head then so be it but ill hate to replace it to then later find out it wasnt the issue AT ALL

i have no means of getting a compression/leak down test done so i really dont know whats going on 100% besides the fact the car runs fine and holds 15psi all the way to redline without a problem. i DID however have some random water on top of my intake manifold in the area where it bends how it got there i have no idea.

what are some of the stuff you guys have ran into over the years that have cause you to have coolant in the oil without it being a bad HG or cracked head?? car is a 91 gsx basically stock (intake exhaust etc)

Head gaskets can leak in many different places, oil to coolant, coolant to cylinder, cylinder to cylinder etc. how long since its been replaced if you know.

I have heard a cracked turbo can also do this.

 

[smorton]

Im going to vote headgasket.... Theres not a whole lot of places in the engine where coolant and oil touch! <-- sarcasm

MY mom actually had the same problem with her 4g63, usually it will mean bad hg..But in her case it was shitty oil..I replaced the oil with good oil for the last year, and no milky crap ever since..Not saying that's gonna be your fix..Just saying It's most likely a hg..

But a leakdown test would be a good idea..If you can afford to take it to your local shop and get checked..You could try tightening your head studs, sometimes they can back out..So try getting the lekdown test done, and checking the headstuds for sure..

Then go from there..

thanks for the quick replys!

it was replaced by the previous owner (or so he claimed) ive driven the car about 2k miles since ive bought. had 114k now has 116k

ive heard about that headstud issue plenty of times. my last oil change was with some mobil 1 oil that was said to smoke a bit (mine did for the 1st start up. white. never again) do to it being thin something about a bad turbo or something

 

[Bud92gsx]

So you had a bad turbo cause that would cause smoke..

But try my suggestions, and if that don't work..It looks like your going to have to remove the head in wort case scenario..

i still have that turbo and it has a bit of shaft play actually but nothing crazy just up and down mostly. WHITE smoke tho!? when i 1st saw that i already assumed bad HG and that was a while ago.

i dont overheat either ever since i put the new radiator cap

 

[Bud92gsx]

So bad turbo and possibly bad hg....

Still try those things out, the leakdown test, and tightening the headstuds, then change oil and see if the problem is still there..

alrighty ill give it a shot thanks. wouldnt a bad turbo smoke like crazy out the back tho? or maybe its just bad enough to mix water and oil together...

 

[4g63 PowerBlock]

White smoke means water burning. I would get problem fixed soon cause -_- that white smoke damages O2 sensors bud.

and well you could try head gasket sealant, just in case the is a couple hairline cracks in gasket the sealant can fill those in with liquid copper...

just chipping in to see if you solve your problem.

i suggest you try something soon, before you spand loads of time and or money on gasket job.

the car isnt moving anywhere till i figure this thing out and spending time/money on a gasket job exactly what i dont want to do which is why i started this thread to see all other possiblities of coolant and oil mixing.

by gasket sealant do you mean that stuff that you put into your oil!? ive been told that stuff is no good

Blows turbo's smoke like crazy..I smoked up a whole block once letting my car idle witha blown turbo..

You could have added the 02 sensor thing withought attacking me..On your very first post I might add..Also can be bad turbo causing white smoke.. Read here.. http://www.dsmtuners.com/forums/newbie-forum/123603-smoke-colors.html

 

[griffin81]

you could go to sears and get compresion test for close to $50 bucks
Start with compresion test first then move from there

 

[AG 305]

my turbo doesnt smoke 1 bit it only smoked that 1 time which was on the initial start up after the oil change. its the same oil thats in the car now. doesnt smoke not red blue green yellow black white or orange.

how about having over tightened the oil filter and breaking something? i would THINK that causes some crazy mixing

 

[Bud92gsx]

You can rent a compession tester from the local auto parts store.. That's also a good idea, since you don't know what your problem is for sure..

Tightening the oil filter too much should just crack the housing..So if you think that could be a problem, take off the filter, wipe it off and check for cracks..

MY computer is gonna die..I'll be back in a few hours to check up on this thred..

 

[AG 305]

ok thats cool thanks.

if it turns out to be the HG which im 95% sure it is... is a felpro auto parts one good? my car is bone stock on 14b. might as well get a new timing belt and water pump. parts store brands good for what i got going on now or OEM all the way?

Blows turbo's smoke like crazy..I smoked up a whole block once letting my car idle witha blown turbo..

???
i wasnt attacking nobody bro, woah!?
i guess things are rough out here, and yess i know all this because i had blown seals and that caused my to fill the streats with white smoke and made both my o2 sensors go bad

(Im just tryin to help man, relax)


Now back to the question, no you add it to your radiator, its a copper color they sell it at autozone or advance auto

i used that on my N/T and it did the trick, just process took about 1 or 2 hours
its called "BAR LEAKS HEAD GASKET REPAIR"

Do not try to plug a cracked head or leaking HG with some miracle fix-all fluid. All you'll do is clog up small passages where you want oil to flow, or gum up the radiator (for coolant additives), if anything. With the cylinder pressures that your gsx sees, you have to fix these problems correctly or you're asking for more trouble than you already have.

It's a horrible idea. With water in his oil (and in the bearings and every other part of his engine), the last thing he needs to be doing is repeatedly cranking on it to find out something that doesn't matter right now.

Tightening the oil filter too much should just crack the housing.

No.

On a water-to-oil cooler it will crush the internal fins and cause oil and water to mix.

*********

Guys...he has water in his oil. Whether or not the car smokes, the turbo has shaft play, what his compression is...it's all irrelevant. The fact is that water in the oil means he may already have possible bearing damage. His first priority is to figure out WHY he has water in the oil, and then make sure he hasn't damaged the bottom end.

OP...

There are two likely sources for oil and water to mix; the head gasket, and the oil filter housing...if you have the water-to-oil cooler. (I believe they appeared during the 91 model year, but not sure exactly when). It's possible for water and oil to mix in some turbos, but probably not very likely (Justin could speak more to this). There are a couple of other places where it could happen (cracked block or head for example), but they aren't as likely.

Your best bet at this point is a leak-down test. You can buy a tester for $30 from Harbor Freight, or probably get a loaner from a parts store for free. All you need other than that is a source of air pressure. Here are a couple of articles they may help you out if you haven't seen them:

http://www.dsmtuners.com/forums/articles-engine-fuel/338152-compression-leak-down-testing.html

If you have the water-to-oil cooler, pull the oil filter and you can then remove the cooler from the filter housing by removing the large center bolt that the filter screws onto. It's not very easy to tell if you have crushed fins deep inside it, but you may get lucky and be able to see something obvious.

You have the right idea in not running the car until you find the source of this and can keep some fresh clean oil in it.

Mitsu OEM composite will work just fine for your setup.

i am a strong believer in no band aid fixes. i know the 90 models were the ones with an external oil cooler so i must have what youre talking about. then again on my last oil change i really didnt tighten the filter all that hard.

general question: when you overheat a car to the red point what happens is the head gasket fails and the head warps right? and i dont mean just reach the red point 1 time i mean STAY at the red point.

Most likely...except the head warps first, and then the gasket fails due to combustion, oil, and/or water being pushed through and over it.

Dare I ask how that happened?

BTW - Unless that was a rhetorical question, I'd say you already know why you have coolant in your oil... whether you want to admit it or not

didnt happen just a genereal question

oh well i see myself pulling off ANOTHER head. woohooooo fun

 

[92AWDHX40]

Been there now i have pulliing it down packed, and the engine which i miss rebuild time, oil, water sounds like hg.

I mean pulling it fairly simple, let us know what you find.

Did you happen to drain the oil yet? Doing a leakdown test is never a bad thing to do to be sure.

Also, is it WATER or coolant in your oil? There is kind of a difference. I would drain the coolant. Put 100% water in it. And run the car, see if it mixes straight water in the oil? Bad idea or no? I personally would at least do a leakdown test.

i havent but its what imma do next. im just mentally preparing myself for it its coolant in oil. funny that you would mention it because i HAVE been running 100% water due to me living in where its constantly like 85-90 degrees out. i just put in coolant like a week ago and checked the oil today for the 1st time and saw the milkyness. NEVER was milky when i had 100% water

That's most likely a coincidence. If coolant and oil is mixing, it doesn't matter if it's straight water or a mix.

The only exception to this would be if you have major blowby, and enough water vapor is condensing out of the crankcase gasses to show up as an oil/water mix. Running E85 would make it worse, but still...that would be a considerable amount of blowby and some really humid air.

So.. when did you overheat it and warp the head?
