Our temp was staying spot-on too...

No coolant in the oil either.

We put the pressure tester on it for about 30 minutes and it barely leaked down. It looks like it may have some very light seepage, but nothing that is obviously coolant. It mostly looks like oil leaks if anything. I sent the pressure tester home with Matt so that he can leave it on over night to see how much it leaks down, and if it leaks on the ground.

Jimmy thanks for the help today. Seems to be holding pressure just fine. Glad to have a good wrench so close by!

It was also getting a bit hard starting too, so that was probably a side effect also. Is yours doing any of this?

The exhaust vapor was minimal at first, and greadually got a bit worse w/time...it never did have a coolant smell though...
I notice zero exhaust vapor, and it starts up just fine. I think it must have been low, and there could be a faint leak. Pressure held up fine under test, and no obvious leaks so just gonna keep an eye on it. Thanks for all the advice here!

You know if you lose fluid know what it means .... you won't see fluid and to be honest even though i was 99% sure my head gasket had gone I couldn't detect anything in the exhaust.

what did the plugs look like?

I haven't pulled the plugs yet, me nor the mechanic can find any sign that the head gasket is bad so I am just going to keep an eye on it. I feel that if the head gasket was going out there would be other serious events going on, truck runs great. I don't see any urgency to pull the heads off until I get some additional signs...maybe I am wrong. Jason was your truck over heating, doing anything else to lead you to believe it was the HG?

I would be topping up water a lot ... on a big run it would lose most of it ... I spent a long time in denial. There were no other real signs of a problem ... it was only when i was coming back from a trip to RI and I had to top off every 100 miles or less did i come to my senses and pull the heads.

I tried the gas tester ... couldn't see a problem.

I would check the plugs and keep an eye on it ... pulling the heads off was a 2 day job and i wouldn't want to do it unless necessary.

Keep a really good watch on it during the next few months...Ours didn't show any signs at all, during the early stages - just coolant loss. The exhaust vapor came a couple thousand miles later, and then the harder starting. Hopefully yours was just low, but these engines are notorious for head gasket issues, so keep watching the fluid levels.

Maybe I am not driving it enough to notice. When I first got it, I noticed the overflow was empty. I put about half a quart in the overflow, and drove. Checked it a few weeks later, and it was low again so I added another half quart. All in all I have only put 800 miles on the truck since January and I've only added 3 times to the overflow (not radiator). I did happen to squeeze the main hose from the radiator and a big air bubble made a noise, maybe I had air in the system?

When I get back in town tomorrow, I will hook the pressure tester back up and look again for a leak.

Matt, bring it up to Conclave for the weekend. Probably a 2-hr drive for you. Welcome to the east coast.

Both times the head gasket has failed on my truck there was no warning. Truck was running fine until it lost cooling.

There is a leak!! I hooked the pressure tester up, left it pressurized all night and came out to a puddle this morning. I had laid a new sheet of cardboard under the engine area and there is a big circular spray area the diameter of a basketball. It looks like a mist spray, and then there was a small puddle of drip in the middle of that. I am hoping it is a hose with a small hole that takes extended pressure to release.
The good news, I know there is a leak, and its not going through the engine. The bad is trying to narrow that little bitch crack or hole down.

Iconic. The Rover is holding up its end of the bargain.

You could always push the pressure up a bit ... not too much and add some UV dye to the water ... that Black light you had from you college antics will now be a useful Rover diagnostic tool!

And if you go past 17-18 psi and your pressure cap doesn't pop, you know you have another part to replace.

I think the dye is next for sure. I'm not sure how to test the pressure cap when it's not on when conducting the test...I think it's working fine though as its never popped off.

Can you explain how you would pressure test the cooling system with the cap in place? I know you can pressure test the cap separately.

You can't; I misspoke. But in a video recently posted by trailfitter in youtube, he denonstrates how some kits can test the cap seperately.

So where is the floor stain in relation to the engine, and can you see where it was coming from at all?
Sometimes the heater hoses let go. In any case, if it is indeed a hose, then ALL your hoses are suspect. I suggest that you replace every last one of them.
If it's something more dire like a gasket, well then...
