It is sounding more and more like an intake gasket failure.  Joe-JDC
Joe, you know it's probably an intake leak. But, now you can say that a vacuum gauge doesn't always detect intake leaks. At least mine didn't.

I don't use drip rails under the rocker stands but there is no oil to amount to anything on top of the head when I take the valve covers off. I've got a Precision Pumps oil restrictor in there and besides that. I've put 20K miles on this motor without problems. It happened all of a sudden.
One of the guys I flew with has a bore scope that we're going to look at the cylinder wall with. I won't be able to see the oil control ring but I'll be able to see if there's damage to the cylinder wall.
After that I'll pull the intake. And, I lied to you guys, I thought I used a old style Fel Pro intake gasket. My intake gasket has the word Edelbrock all over it.

Just got through taking valve spring off #2 intake. Wasn't anything wrong with the seal.

Mark,
   When I put the engine together I bought a used Streetmaster intake because Jay B. raved about it so much. Even wrote a book about it. I set it down on my new Edelbrock heads and I swear you could rock it back and forth. It was warped real bad. So, I ordered the Edelbrock RPM intake. When I set it down on the heads it was rock solid, the holes lined up very well and trying to use a feeler gauge top and bottom of each corner showed it was sitting flat. I've never had leaks front or back using RTV as gaskets for that area and for 20K miles this engine has run great. I'll watch your video. Thanks for the reply.

Joe-JDC,
 I have the better heads. When I took the valve cover off (first time in 20K miles) there wasn't a lot of oil at all standing in head. All the components had a good oil film on them but no standing oil. The engine doesn't smoke while idling but if you rev the engine and let off the next time you rev it you'll see some smoke. The real smoke comes under load when you run it up through gears and let it coast for a bit. When you get on it the next time it looks like a freight train behind you. My buddy took a video of me drag racing and it didn't blow any smoke then. It was the next weekend that I went to a car show never putting any stress on the motor that it started smoking. The seals are going to be here this morning (love Summit, order one morning, get what you ordered before 12:00 the next morning) and I'll pull the intake spring on that cylinder and check the seal.

Barry R,
 I'll remember what you said about pressure checking an intake but if the valve seals are good the intake gets pulled anyway. I hate that too because I put a thin film of RTV on the bottom and top of each intake and exhaust opening to each cylinder as well as the water jackets, it's going to be a mess to clean up. The block was a remanufactured 352 for a passenger car that I had the machinist just clean up the deck to ensure geometry of the head intake angles. I felt secure using new heads/intake and the old Fel-Pro gaskets with RTV backup. I don't think I could put it together any better. This new guy that's doing my cast heads says my 25 lb. torque on the intake bolts should have been 35 lbs. though. Just to save some time of me asking,  please give me a part number of the intake gaskets you use on your builds.

Joe-JDC,
    I'm having a set of C1AE heads reconditioned by a new machinist I've never dwelt with before. This is going on a 390 build I'm doing. And, I was telling him the problem with my 410 fouling the plug on one cylinder and going through leak down, compression and vacuum test. He has worked on FE's for a long time and he said you probably got a intake leak and my reliance on the vacuum test I did to eliminate the possibility of an intake leak wasn't justified. He said I could still get good readings because the motor was big.
What's your take on that. I'll be finding out tomorrow anyway when I lift the springs off that cylinder. Thanks

I was just kidding about the umbrella seals but best of my recollection the one's on my 1966 Fairlane GT I owned were still good at 120,000 miles. I really don't know how far advanced you get when you put valve seals on your car that lasts 20,000 miles. And intake gaskets is another one. Don't remember needing to check those at 20,000 miles either. I love progress. lol

Joe-JDC, Edelbrock uses the 9726 Viton seals on my 60069 heads. They claim they don't have any problems but I've found forums on the internet that says they've had them pop off under street use after 5000 miles. Tomorrow I'm pulling the springs and checking the seals. I'll change the seals on the problem cylinder just to be safe. Advance Auto sells their valve seals. I've heard horror stories about the Teflon seals, right now I wish I had the old umbrella seals, I know they last a long time.

The intake is a Edellbrock RPM bought when I bought the heads. I used Fel Pro gaskets (the old style) and I laid a thin layer of High Temp RTV around each intake port, top and bottom as well as the water jackets. I never intended to take them off again and I never intended to take a chance of them leaking. The leak down test was done with a luke warm engine but the comparison is what I was looking for. If the engine had been hot I'd have gotten a better reading on the leak down.
I've got to be pulling this oil through the valve guides, can't figure out where else it could be coming from. Since I've got the fitting made now to put air in the cylinder I'll take the rockers off and put air in the cylinder and take the intake springs off and see what it looks like.

Just did leak down test.  #4 good cylinder 70/80. #2 bad cylinder 70\80. By running 17 inches vacuum steady an intake leak doesn't seem possible or have I been confused on how to read a vacuum gauge.

I've got to weld a fitting on a spark plug to put air in the cylinder so while I'm at it I'll use my leak down gauges to check cylinder also. Don't really think I've got a bad cylinder though. Springs are in good shape.

Guys,
I'm having a heck of a time with my 410. Last week I went drag racing, everything OK. Drove the car that week, no problem. But, I went to a car show Saturday morning and it fouled a plug on #2 cylinder. I've done a compression check on that bank after running the engine a long time. #1-130lbs, #2 140lbs, #3-130lbs, #4-130lbs. ( I think #2 is high because of oil and crud that wasn't burnt) ( I did compression check with all cylinder plugs out).
The engine vacuum is 17 inches idling at 650 rpm. May fluctuate back and forth from 17-16 1/2 inches, more or less steady. I rev it and it goes to @8 inches and then to 26 inches before settling back on 17. Plug is always wet and when you take it down the road high vacuum on deceleration draws oil into cylinder and then burns it when you accelerate again. It will idle showing no smoke out the exhaust but when you put in under load it acts as if I've got bad rings. Changed wires and distributor cap, plugs too.
I called Edelbrock and ask them if they had trouble with valve seals popping off and they said it was unlikely. Cars got about 20K miles on it and @60 drag races. HELP. What do you think.

Sorry guys, we already covered this, I'm getting senile.

Paulie,
   At 70 mph I'm turning 1950 rpm. My 5th gear is .64.
The last truck motor I had was a 74 DTE 105 390. In this same car with same rear end and transmission. All I did was buy a new set of timing chain gears to get the retard out of the cam and I got 20 mpg with it on trips. My 1/8 mile times were the same as the 410 I have now (same tires). It went through the quarter in 15.2 sec. That's not bad for a 250-270 horse engine. I did put a 570cfm 4V carb on it and used the stock heads and stock exhaust manifolds. Making this 410 achieve what the old 390 did is impossible though. Too much engine, stroke , heads, exhaust and intake. I think this 268H cam that gives me another 8% hp and torque at 2000 rpm might let me better enjoy a trip as well as enable me to keep beating my buddies Bullitt Mustang.

I think I found my problem. A website I found that was working on a Moser 9" said that if you didn't put RTV on the splines of the yoke when you installed it you'd get oil seeping through the splines. I think that takes care of that.
