I found some 'rubber dam' material in Okla City at a oil field supply house. Sold by weight and is dang heavy (and expensive) Used it to block the air behind the right headlight into a 2nd cooler I have in the transmission oil line and the fresh air inlet to the cabin vent. Thought I could get a picture of it while the radiator is out but can't get a angle on it to see.

454 vortec 7.4 water in oil, trying to trace source

Google search came up with this site specific to 454 and this major problem.
We had MH ready to roll except for an oil change, on draining oil noticed color even while under MH, rusty and cloudy, cancelled trip.
Prior to this no indications, no smoke, no loss of coolant.
After discovery did see radiator overflow tank was down below min and had been slightly above max. Research came up with head gasket, intake manifold gasket failure and condensation.
Did the pressure test on cylinders and they all pressure test 160 with a couple up to 180 but all held steady, head gasket and too much water for condensation and the missing antifreeze.
From reading this forum, cooling radiator might be sharing with oil.
Too wet out right now to crawl around under MH to check the backside of radiator, to see if I have oil lines into it.

My question is: What tests can I do to isolate source and solve?
Physically getting to intake manifold gasket to see and replace requires a lot of effort, which I will do after I have exhausted all other possibilities.

Did pressure test on the radiator and it didn't pass! Isolated radiator from engine and it did. On doing google search 454 evidently is well known to mechanics for intake manifold gasket failure, I did see a small weep from the intake manifold gasket bolt next to the water pump. Upper intake manifold plenum gasket was good, when I got to the lower gasket I was amazed that the engine ran with deteriorated gasket. Plastic gasket held up 15 years, plastic was cracked, and split at the front and back of engine.

I'm stumped

Geez Keyair you seem to be everywhere and with all the answers. Good to know though. I have a 1981 280 Excella motorhome. Since it has a 454 and 454's seem to be readily available still I figured parts would be too. Nope. took this device to a chevy house and the guy had no idea what it was. An older fella in the parts house identified it but they had no part #'s and determined that the part was NLA. Since it appears to be a non-item nowadays, what do I do to replace it? The device is the cruise control assist. As you can see mine is long since DX'd. I've seen some similar, but which one(s) adapt best to the Airstream 454?
I have another question but it has to do with capt's chairs. Should I post question and photos here or is there someplace better? I'm a bit perplexed with search results as I do a search and receive an answer that there are 1-50 answers in 1349 posts which makes it somewhat difficult to find the answers needed in a timely manner. Any suggestions for swifter results?
Pulled up the carpet today to discover a nice layer of white sand underneath. Going to be an interesting fixer upper. Thanks in advance for all your help. Sincerely,
James

James, I may have the assist module. At least I had one 6 months ago when I stumbled across it sitting on a storage shelf. I'll look this afternoon.

The other option is to replace your existing cruise control system with a new electronic system by Rostra. I've had good success doing the swap as have several others on the forum. Just search for Rostra.

Here's one link for a Rostra cruise control installation.

Starting a new thread would probably be a good idea. That helps keep things organized on the forums.
