Ok, this is interesting. Was that 4psi on one cylinder or 4psi on all cylinders? Did you do the test yourself or are you getting this info second-hand?
Remember buddy, we're here to help, not to yell at him.
We all need to take a step back and relax a bit. John, it's frustrating when you ask for help but provide little information when asked questions. Try to be as detailed as possible when responding so that we can help you better
Oh jeez, really? I am well aware that we are TRYING to help. Can't help someone that won't assist even themselves I'm out

No but I have some of the old oil I'm sending. And I'm 99.99% it will come back positive. But we will see!
Positive for what? Coolant in the oil? John, if there had been coolant in the oil none of the leak down/compression crap would have been necessary. Anyone could have looked at the oil and seen it, especially given the quantities you say the system is losing.
That means unless there are Hydrocarbons in the coolant you do not have a bad HG. Have you tested the coolant for HC's?
If not, it's time. If that test comes back negative it's then time to find where the leak is, get on with life, and drive.

Yea coolent this is the old oil and it's green as hell.
So there is oil in there. How would one test for HC.
Tool is available for "rent" at Autozone. I just used one. Paid $50 to rent it and got my money back when I turned it back in. See the video link for details.
The whole problem is that he's losing 1/2 gallon of coolant and maybe a quart of oil every 250 miles. He found a UV dye to put in the coolant and there is a green tint in the oil after adding the dye. This is the only test he's been able to find that indicates the exchange of coolant and oil inside the motor.
Other than that, we've identified a rear main seal leak, but that's it. He's trying to figure out where the coolant is going.
Ok, couple of questions:
1. As shown in that leak down test video, the whole point is to see IF pressure is lost, and then if it is, WHERE that pressure is going. Otherwise it's just a compression test. What exactly did they do other than identify that there was 4-7psi lost??!?
2. They stated that there was no coolant in the oil, but how did they determine that? Did you tell them about your dye test and ask for their thoughts?

This has already been done. And it passed ! One of the first things I did
10-4. No problem. You asked how to test for HC in coolant and I gave you the info. Sounds like this is not the issue anyway.
What about the front and back heaters leaking? That will leak into the truck. Dont it? I know u r not using it but who knows. Good luck.
Roger that. The thing I'm getting at is (regardless of the Dye test) coolant can't be dumping into the oil in that volume without the guys at Toyota pulling out the dip and saying "Oh crap, there's a ton of water in there". That means unless there are HC's in the coolant the head gasket is fine.
Test strips for finding HC's in coolant are dirt cheap but it sounds like the guys at Toyota did not test the coolant.
Then, if that comes back negative, put the head gasket notion to rest and find out where the coolant is really leaking.
Completely agreed. There's no froth in the oil, no milkiness, just this dye in the oil that was supposedly not there before. I also agree that the current problem is not the head gasket.
John, listen to rice!!
