2uzfe Head Gasket

I found a drop of the dreaded milk shake while under my 2000 single cab. I opened up the oil cap and found some evidence of it being in there as well. I guess I have two questions: Is this guaranteed to be a head gasket? And does anyone have an idea of how much this is going to cost? Unfortunately it’s not something I have the time nor the skills to do mysef. It doesn’t idle rough, doesn’t have white smoke, it doesn’t overheat, and hasn’t thrown and codes.

 

It's normal to find sludge inisde the oil cap, FYI. It comes up so often I'm tired of telling people about it. Like, it's totally normal, there's a shitload of pictures of it on here. ESPECIALLY if you do short-trip driving (under 10 miles per on/off). Steam tends to build up in the crankcase (especailly if you don't change the PCV valve on schedule!!!!) and the highest point in the driver's side head is the oil fill tube, and you end up with oil butter in the cap.

What is this "drop of dreaded milkshake" you found under the truck?

 

I’m talking about like a cream/off-white colored oil and coolant mixture. The truck hasn’t been drive much recently apart from a 350 mile trip a couple weeks ago. It has been raining a lot recently and the truck has been outside during that. When I mean under the truck; near the crank case either on the frame itself or on some tube/or wires. I can’t remember exactly.

haha I can imagine your frustration. I’ve seen you on almost every post about something similar. The reason I say dreaded is the context I’ve seen it before has been the complete death of powerboat engines when the gasket goes, and seawater and oil mix.

Are you talking about The dreaded “pink milkshake”? That isn’t a head gasket problem at all. It’s a radiator problem. Investigate further and report back. How’s the radiator fluid look? How about the transmission fluid?

 

That isn't how you find HG leaks....you find that when you drain the oil. On the outside like that, it means nothing, just water mixed with the usual oil leaks, road sludge, etc.

It's when you find that INSIDE the radiator, or the oil pan that it's bad. And as noted, a little on the inside of the oil cap during wet weather, when it hasn't been driven much, is normal.

Thanks a ton guys! She’s getting some more work this week so I’ll have an update at some point. I’m new to working on cars and definitely prone to panic. I’ll definitely check out these links!
