I saw a sort of milky substance like chocolate milk when I looked into the oil cap. I called a shop and they said it was anti-freeze that is getting into the engine. Does anyone know what is causing this and how to fix this?

 

Head gasket blown, replacement required

 

Most likely a faulty head gasket.

 

I cant just tighten a nut or something?

 

tighten a new motor

 

Are you serious? Why?

 

if you leave it like that it will seriously damage your car, i had to replace a motor in my old car for the same reason. easier to replace the gasket than to replace the engine. (blew gasket before i knew anything about cars)

 

it will most likely be cheaper to replace the entire engine instead of having the work done. Our engines cost pocket change.

 

If you only saw it ON the Oil cap I think thats ok..Thats moisture that was trying to escape.. I also get that but only in the winter. I used to get it on my Jeep and my mom gets that on her Jetta...

Its Normal, wipe it off and I garentee it wont come back..

Nope it's all in there like someone jizzed in it.

 

Just look for an engine with low miles on it. It will be cheaper then doing the headgasket and better for the long run.

 

lmao...That could ruin your engine too.

 

it could also be a cracked head. if i were you i would put a nice 3.5 in it.

 

is that only on the underside of the oil cap when engine is cold? but goes away as the engine is warmed up? hopefully it's this, just some condensation...

btw, what's it look like on the dipstick?

 

Ditto. Two summers ago I helped a friend pull the engine out of his boat. It's an '85 Mastercraft competition ski boat with a Ford 351 Windsor. We were out on the lake and the boat was running like crap, so we checked the oil and sure enough it was like chocolate milk. One of the heads had cracked and water was getting into the oil. We considered just putting on a new head, but fearing that damage had been done to the bottom end bearings, he decided to get the engine rebuilt. If it had been the end of the season we would have done the motor ourselves over the winter...but it was only June and he wanted it back on the water ASAP.

Unfortunetly it would probably be best to get another motor. It's highly likely that your engine needs a serious rebuild and it probably isn't worth the cost over getting another motor. A 3.5 swap would be nice but it's costly in terms of both time and money, and from what I understand there are still bugs being worked out in this process.

If it was me and this was for a daily driver I'd swap the motor with another VQ30 and then rebuild my original on a stand in the garage, and do some upgrades while I have it apart.

 

In any case your engine is rather buggared. It would be nice to put a 5th gen motor in it, but that's going to take extra time and/or cost a good bit of extra money. If they were quickly & easily swappable like that then it would be better, but unfortunately they ain't!

BTW have you had the car overheating lately or anything?

 

good point

 

I would concider another engine too. it's better to get a motor that hasn't had hands in it, than to start pulling your's apart and back together.

 

You don't know much about engines do you? There's no tightening of anything. You need a new motor.

 

Flux capacitor has a leak. Call Autozone for a new one. About $25.

 

Tightening is a nice thought, but not how it works. I think a weakness in the gasket gets exposed over time from the internal pressures and eventually blows out. It may be in the initial stages of doing so and leaking into the engine, but at some point it will blow and your engine will overheat quickly.

Don't scrap what could be a perfectly good engine because of quick quips over one symptom though. If you drive a lot of short trips, especially during colder weather, then I think it's possible that it could be condensation build up in your engine. Whatever it is, you need to find out why, soon. If you drive it too long with an internal leak problem, a new engine may be the only option and not just one of them.

Plus it's easy for guys who aren't paying for it to suggest it. Paying for someone else to take out and put in a new engine isn't near as cheap as having a head gasket replaced. Unless you're one of these guys who can do it yourself and go without transportation for a month while you're doing it after work and on weekends while taking the bus. I'm guessing you don't have that option.

Good Luck.

 

its 600 bucks just for the gaskets, and while your at it rebuild the heads since you have to remove them anyway. it can become very costly, your talking a couple thousand i know i just had my engine rebuild. if it wasnt for my boost,i would have gladly spent 500 bucks for decent motor from the junkyard which is the way you should go. for the mean while try some of that miracle stuff thats's suppose to seal the head gasket until you pick up another motor and let us know how it works.

 

theshawn is right:

This sucks. Its not like changing a tire. Well I'll take to the mechanic and see what he has to say. I dont have the capability to change the engine myself. So I'm guessing that the mechanic would probably charge me about 12 man hours to do it.

The car has been driven over 500 miles like this. I have a 100 mile commute (round trip) I dont think it's condensation. The check engine light is on. I'll check the code. The car has not been overheating, but I have noticed that one of the anti-freeze rubber tube is leaking at the connection to the radiator.

 

then the cars fine, its pregnant! congrats! what do they start of as sentra's, then grow into altimas, you lucky devil.

 

you need help

 

lol so if you have a gangbang what u get? a skyline? or you wait till it gets old into a datsun?

 

mmm i love chocolate milk.

Try doing an oil change and use some good oil ( no proline type crap)

But ya if its as bad as you say it is , you should start looking for a new motor
