Good job Paul, its a good feeling to fire up an engine for the first time.

I had the same over heating problem when I fired up my 401 for the first time. I ran over and grabbed the garden hose and ran it slowly over the radiator to cool it off a little. Later my electric fan controller died on me twice causing the engine to overheat while driving, finally went back to a mechanical fan that works every time.

No, it is definitely oil. Smells like oil, looks like oil.

I was all excited and happy for you as the engine sounded great but now I feel bad for you since it seems to be burning oil. Check the plugs to see if one cylinder is the obvious culprit. Hoping for the best.

Oil being drawn in thru the PCV. Check inside the breather cap and hose.

Rings not seated yet. The time depends on the type of ring, I would say at least 2 or 300 miles.

I wasn't looking at your thread when the head was done, valve guides were ok?

The machine shop said the guides were ok. It idles great, has good oil pressure, my computer connected to the diagnostics port says the TBI is not running rich. But it puffs thick oil smoke when blipping the throttle. Do not see it any other time. I'm done for now. I will call the machine shop and see if they have an opinion. Right now I just want to give it away and call it quits.

I guess I will ignore it for now. The whole reason for the break-in now was to address any issues before the CJ was completely assembled. Once I am on the road if it continues to do it I guess I will address it then. Unless someone has a strong opinion to take it apart and inspect, rings, etc. I guess a leak down test would tell all, huh?

If you can find the part numbers of the valve seals, check them out. On the engines with bad valve seals that I've had, there would be no smoke at idle. Blip the throttle , blue smoke. The smoke also presents itself at first start up on a cold engine.

On a AMC V8 there are a 2 different kinds of seals, one requires machining of the guide shoulder. This is why I would check.

The valve seals were part of the comp cam kit I purchased. Came with the cam, springs, seals, timing chain, lifters. They are the rubber umbrella type? Can I reach inbetween the springs with a screw drive and push them down?

Take a break Paul. Walk away from it. I have been there countless times. I understand completely! Wait until the motivation and energy return to pick up your tools and fiddle around again. There is no penalty for that! You will be motivated again, and you will solve this mystery. But working on it when you hate it is not good for anything.

Plulled the plugs before stopping for today. Something going on with 5/6. Oil on the base. I could see oil smear on top of the #5 cylinder using a flash light.

You should be able to, are they up a little?

I disagree with Scott, when something like this happens to
me I jump right in on it. The longer it sits the less I feel like working on it.
I would go on NAPA or CarQuest and search for seals. See if I could find a picture. Then compare them with what you have. Or go to the the store have them look and bring up a picture. I would also skip a JF search and go right to Google.

Some of the V8 seals have a metal band around the bottom, some don't.

I would suspect the intake side , before the exhaust, oil coming down the exhaust valve when it opens would be pushed right out the exhaust. The spark plugs would tell the story.

I've never done a I6 I've only done a 360 and 304 .

Off topic but the last seals I put in a V8 Chevy 350 used different seals on the exhaust .

Given the plugs above, and the fact that 5 and maybe 6 are oil fouled, what would you do next? If I need to open up the engine I am not gonna screw around trying to do it in the rolling chassis. I would just pull it and put it back on the stand.

For kicks and grins, maybe a compression test to see if 1 through 4 are different than 5 and 6.

Swap the plug wires from 5 and 6 with 2 from 1 thru 4 , whichever fit. Fire it back up.

Also put the plugs from 5 and 6 in the 1 and 2 spot. Simple things first.
