So we are on the road for a spring break trip at a gas stop. I went to check the oil, and was greeted by the dreaded milkshake of coolant in the oil. No oil in the coolant I can see. We are in Plains, TX, which is pretty desolate.
Here’s a brief history of the mechanics of the coach recently:
I had changed out the heads last year due to a burnt valve, and drove the coach on several trips since then(including one to Florida from Texas in the middle of summer with only one issue. The coach chucked a belt on the Florida trip, which jammed the water pump briefly. I was able to stop it immediately before it overheated. I replaced the belt with the proper sized one on the road. All seemed fine at that time so I continued with the trip.
Before our current trip, I decided to change out the water pump and fan clutch as a precaution from the trauma from the thrown belt. All went well with the water pump swap and the coach ran fine for about 500 miles since then. Till now, of course.
My thoughts are (assuming nothing is cracked) intake manifold gasket leaking water into the valley... But would welcome any advice from the gurus on this site. Soonest the local auto parts store can get the intake gasket here is Wed, so thinking of buying some gasket material and cutting one out just to get us home. Then change the oil several times and hope for the best. We have a Jeep dinghy at least... But wife and 2 kids are less than thrilled.
PO had used grade 8 manifold bolts, which I reused on the head swap. Have since learned this is not a good idea, but had not changed them out as everything seemed fine.
Definitely changing them now. Any advice on how to best seal up the manifold, if that is indeed the issue? Appreciate any of advice or suggestions

Must have overheated the engine without knowing that the standard temp gage
will never go past half mark and kept driving.
My experience with customers.
Call me and I will advise you.

Is the coolant low? Are you sure it’s not just combustion water from some short trips and stuck open thermostat? I’d look in the overflow for level, and in in actual radiator. Then pull the oil plug and see what comes out. I’d say if not bad I’d Barsleak it and see what happens. Just to get to somewhere with a good shop.

Thanks to all especially Matt who super-sleuthed my phone number.
Jim: VDO gauge. Did slightly overheat to 230 before I identified a problem with my upper rad hose sucking closed. Could, be due to the heat, but that was 500-1000 miles ago.
John: yes, for sure... overflow empty... Milkshake in the breather, too

Upper radiator hose is on the pressure side of the water pump not the suction side.
How can it be sucked in? Is something putting suction on the whole coolant circuit?

When the engine cools down, the coolant contracts providing negative pressure on the whole system and sucking in replacement coolant from the overflow container. They do make some hoses with an internal stiffening wire to prevent that.
