soooo strawberry milkshake or some other terible problem??

[Jc12]

Hey guys, so my most recent purchase ..99 4runner limited 250km soo 160miles ish i suppose.. i just gave it its first oil change and find this.. so far the truck has been running great, it does a bit of a delayed shift from 2-3 when cold but i have experienced that with a number of other runners, and hasn't hicupped in any other way. Here is what the oil looked like, in the photo it looks a lot pinker than it actually was, the color is more of a dark rusty color and the layer on the top were tiny bubbles.. the photos do make it look thicker/worse than it was :|

My initial guess would be that water/coolant would got/getting into the crank case. The reddish brown would be from rust.
Maybe you have a gasket leak of some sort somewhere (water pump, intake, head, etc.).

That is not normal, I would stop running the truck until you find out the issue.

If it was a strawberry milkshake, it shows up in the radiator. It will start pukeing out the overflow and the radiator will have trans fluid in it. I would check the radiator.

I would guess that coolant is getting into the oil. (blown head gasket or cracked head or block)

Could overfilled oil cause this? I had it inspected only a few weeks ago and it passed with flying colors.. Would I not be overheating if It were HG? Should I do a compressions test? Trying to keep the cost of diagnosing down, gotta live being on a budget

 

[PitbullRescuer]

It could've blown a headgasket since inspection. But if it's running okay, I would just do the oil change and keep an eye on it. If it had a blown headgasket it would br running like sh*t.

It may have been some type of oil additive that caused the oil to turn that color.

If you are not losing any coolant, put in some new oil, drive it for 1000 miles if nothing else happens, and then drain it and see if it is the same color as what you just drained.

Check your coolant level, if coolant is getting into the oil, it's leaving the coolant system and should be low. That doesn't look great though. I'd try a compression test as well to see what comes up.

 

[Jc12]

Will do, i just topped the oil up and checked the levels there are a number of small bubbles on the dipstick after i topped it up and ran it for a minute or so, if it makes any difference the temperature is a little below freezing here.. no idea if that impacts it but anyways thanks for the help so far ill update you after i give it a healthy road test.. any write ups done doing the HG .. never thought it was an issue outside of the 3.0's

 

[the great him]

any motor can blow a head gasket, even the 3.4l but yes your are correct that this was a major problem with the 3.0l toyota v6.

Are you guys nuts?
I would freak out if I saw that in my oil. Something is making that oil look like that. Head gasket, waterpump gasket, cracked block, etc. etc. etc...
YES it is possible for the engine to run "fine" with one of those issues going on. If you do, you are just on borrowed time and going to make a problem a bigger problem.
Compression test, check the engine for leaks, don't jump the gun and change the HG.. It could be a water pump gasket (which if it is, do a timing belt, waterpump and call it a day)... start small.. diagnose, fix the problem. Don't just throw parts at it.

Its not a "change your oil and see what happens" scenario.

 

[eplanajr]

I too had oil come out of an engine that looked like that...

... that engine had been sitting outside for several months with no intake manifold on and exposed to the elements...

It looks like coolant in the oil, most likely from a blown head gasket. I'd do a compression check on the cylinders, which might not show a problem if the gasket is blown between a water passage and oil passage.

You can borrow a coolant pressure tester from O'Reilly's (or other parts store) and pressure check the coolant system. Pressurize it to about 20# and see if it leaks down. With that much stuff in the oil, you should probably see the pressure leak down slowly (1-2 minutes should be enough to see the change). If it leaks down (or the compression test shows a problem), pull the heads and check it out. It could be a cracked head or block or a gasket, but either way you've got to pull the heads.

If the compression is good and you don't see leakdown in the cooling system, I'd change the oil and check it in a couple hundred miles (change it again) to see if it's okay. Since you just bought it who knows what the last guy might have put in it.

^He's spot on w/ this one. I wouldn't keep driving it until you get her diagnosed..

 

[Jc12]

I'm guessing this is irrelevant but when I took off the oil drain bolt I only had to use my fingers it was on there so loose..

 

[Jc12]

Okay, so I am doing a compression test today then have a friend of a friend who Is a Toyota tech who will look at it. He will be checking it out at his house so what tools/equipment should I have him bring.. Anything and everything, thanks guys!

Agree with this 100%, however I would leave the pressure on the system for at a minimum 30-45 minutes to be sure. If HG, you'll likely know within 5 to 10 minutes, but it can take longer to leak down depending on the blown spot.

The 3.4L in our 3rd Gens actually like to blow heads/head-gaskets between 175-225k miles. This observation is based on a year (only 1) of trolling T4R and my own personal experience with a cracked head at 199,800 miles last April.
