Did a short drive Saturday and everything was fine. Headed out this morning to put a hundred miles or so on the new cam before we headed out to a rally. Got about 15 miles and the coach started coughing and missing. Got off at the next exit and it idled fine. Also the oil temp was showing very high...275 degrees. Cooled right down.
Headed back toward home and it was missing bad. Tach was swinging wildly which made me think ignition but it sure acted like fuel.
Got off at the next exit at a truck stop. Idled fine, oil cooled right down. Changed the module...no spark. Put the old module back in...no spark. Checked the new pickup coil and it was open. Oh, and the Onan was running like crap and wouldn't hold the AC unit. The automatic transfer switch kept dropping out. Onan finally was running on one cylinder and I just shut it off. Shortly it was 112 in the coach and 97 outside.
At that point I called Allstate road service and ordered a wrecker. This was about 1 pm. About 45 minutes later they called and said that the wrecker would be there at 3:45. Checked at 3:30...on the way...and 4:30....and 5:30...and 6:30. At 7 I cancelled them and called Allstate back and went home. A buddy had been hanging out with me at the truck stop for the previous 6 hours. About the time I got the 15 miles home, Allstate called and said the wrecker was at the coach and did I still want to cancel them. I told them no if they would wait 20 minuted for me to get their. They did and we dropped the dead coach in her parking space about 9:45.
Not the best day I've ever had. I'll put in my spare distributor tomorrow and see if it fires and go from there. The swinging tach still makes me think it's electrical. I changed the pickup coil back in the early stages of my engine woes so it could be an early failure of a Chinese component. Certainly would not be the first time.
Ken Henderson said the hot oil is probably because I put 6 quarts in and it was frothing. I sure hope that is it. I'll drain a quart and see what happens.

Perhaps. I filled up Saturday at a local place that is always busy. Doesn't mean they didn't get a bad batch. I'll drain some and see if an water separates out.

Boy, Kerry, I don't think you should buy a lottery ticket.
I will grasp at a few straws here.
I go to timing. Retarded spark? This could make the pistons hot which would heat oil.
How was the engine temp? But if you have an aluminum radiator, it may be able to overcome extra heat.
I mostly fiddle with Electronic Spark Control modules but have seen a new US of A module that was bad out of the box. Swinging tach makes me think module. I also had a bad connection at the conning tower of the distributor and my tach was all over the place but that would not cause overheating of oil or missing. I remember we covered that the timing order was correct.
The degradation of spark makes me think coil. But modules can break down in heat as well.
1) Vac to the vacuum advance?
2) Weights moving?
3) Cam timing correct. Good compression?
4) You said you checked the damper so that should show you correct timing. Worth checking?
5) Mixture lean? Sucking air from the valley via bad intake seal? (Disconnect the PCV from carb, cap it and put a plastic shopping bag over the breather hole on the left valve cover. At idle you should have a bit of positive pressure. Hang on to it, I saw a 403 almost inhale the bag.)
6) Crack in the intake opening with heat?

Might want to check the Lobe sensor around the shaft for connection and
check run out at shaft.

Kerry,
I suggest you make a list of everything you did and what new parts you installed when you R&R'd the heads and see what could effect
engine temperature.

News...good I think.
This morning I swapped out the distributor in about 5 minutes and it fired right up. The pickup coil is definitely open. I checked resistance on the pickup coil in the spare and it was 800 ohms or so.
This may or may not be the issue with it missing and coughing but the probability is high that it is. The next test drive will be in a local subdivision that I could pull it home from if I can't make it. To be honest, I'm a bit nervous about the next test drive... The wife is losing confidence and I can't really blame her.
If the wrecker company had been honest with us, I'd have come home and got the spare distributor yesterday but I was fooled by the '...30 minutes' spiel from the wrecker company.
I'll drain a quart of oil and make another test run. Not going to drive it to the rally though.

Kerry,
So sorry to hear of this. In my experience engine voodoo comes in patches. Seldom is only one thing wrong. It seems that a gremlin lives in the machine and it begins to break things just to see if you can outlast it. The good thing is that if you outlast it, it submits, sometimes for years. Like Gene said, you will do this, one thing at a time. And, you are educating the rest of us so that our spouses won't lose confidence if we make sure bad things won't happen.
But, being on the frontier fighting the unknown is difficult. Thanks.

Gee Kerry you are supposed to keep the spare distributor hidden away on the coach somewhere where you can pull it out and screw it on before your wife gets too excited sitting on the side of the road. Save the wrecker for the times you really need it. Believe me I've been there and they never forget.

Depends upon the "tow" vehicle. Front wheel lift by tow trucks that pull 18-wheeler rigs (tractor AND trailer) to service locations work just fine. Air up the rear end to give added clearance to rear bumper, trailer hitch, black tank, sewer outlet, etc., and you'll be fine. Rob Mueller's tow procedures have additional info.

Yep, Medium size wrecker with a wheel lift. 5 minutes to hook up and drop. Didn't even have to take it out of park. Raised the back in as high as I could and home we came. the BIG semi wreckers aren't a good fit because the size of their wheel lift arms means they have to lift higher and the rear end is more inclined to drag. And the 1 ton pickup wreckers (small) can't handle the weight.
AllState paid the bill. I don't even know how much it was.

Kerry, check the ground strap on the transmission to the frame crossmember.
Also, not a bad idea to ground the distributor to the engine. I think that
Dick Paterson distributors have a stud and nut specifically for that
purpose. It is important for the longevity of distributor components. Man
you have been snake bit on this cam stuff for sure. Hang in there. Things
will change. Maybe even for the better (grin)

Kerry,
Our local junkyard usually has one or two Chevy V8 distributors on the shelf
in the back room.
If it looks decent, I pick it up. Ten or fifteen bucks. Usually genuine GM
module and correct
pick-up coil. Also all the parts except the housing are correct spares for
those Cadillac motors
you have. With a little bit of rework, the housing becomes a Cadillac
distributor. You can't
beat genuine GM parts for quality.
