I had an exhaust manifold leak, which led to a valve job due to broken studs in the heads. I had the heads resurfaced also. I got it all together this morning, fired it off. I've got billowing white smoke out the exhaust. I had a bad water leak at the right rear intake area. I just got done pulling the intake off,but am not sure if I need to go further. Would an intake leak cause this much smoke? or would it have to be a head gasket?I had no problems before pulling the heads, it only has 50K miles on it.I've used the same machine shop many times before, so don't believe it's anything he did wrong. I used standard Felpro blue gaskets,really can't seee where it was sucking water? Could the cork gaskets keep it from sealing by being too thick? They look like they compressed OK.Is there a better gasket to use than the standard 90109 Felpro?

I had a ford go into hydraulic lock because of a bad intake gasket. If the resurfacing was a small amount I'd replace the gaskets and make sure you torque the intake properly. A head gasket leaking in a way where you are seeing significant steam usually also involves overpressuring the cooling system.

Also, I have to agree on the possibility of leftover coolant in exhaust from initial problem. I always had to drive the 89 and 90(bad batch of gaskets those years) chevys around quite a bit to burn out the exhaust system after head gasket change.

I just finished changing head gaskets on my 440 because of this.

The heads looked good when coming off, so would not think they took enough off to cause a problem with intake sealing. It's possible some coolant got into exhaust pipes when pulling heads, but the smoke never let up. Everything was free of coolant in cylinders.I did not look for bubbles, but also did not run it very long-probably 2 minutes each time(twice). I guess I'll just order another set of gaskets and try again.I may try for a better intake gasket set which may seal a little better. I've built about 5 318's, but never had a problem with them.

It would have to be going in after temps get the cooling system to pressure or even after I shut the car off. Any ideas on how to check for that? I guess I could try a pressure test on it....

I pulled spark plugs one by one and found the problem-bad head gasket.The leaking cylinder plugs will be very clean.

Trying to follow two questions from two people in a thread is confusing.

I would do the following: Don't pull the heads just yet Fix your intake(s) leak, and be very careful with your gaskets, and make sure everything is clean. Pull the plugs and inspect to see if you can determine which hole(s) are affected. Run the engine up to temperature, and if theres no identifiable leaks you can find--other than exhaust steam,--then pull the plugs again and look for suspects. I'd bet your intake leak is the start of the problem.

It takes a while for things to clean out after being apart. Don't expect it to run clean right from the get-go

I gernaded the 340 in my Dart. Let the car sit for three years before putting the 6.1 in it. Apon start-up of the new motor, things were fine. I took it down the road and tons of white smoke out one bank. I Swore I blew a head gasket. But after a while, smoke dissapated to nothing.

Anonymous Unregistered A	Years ago I put a low miles junkyard 340 in my 70 RR ( the FIRST gas crises) I ran that thing a week or more before it stopped burning oil. It had less than 20,000 miles on the wreck (I saw the car). I even ended up complaining to the wrecker. He assured me it would be OK and that they'd stand behind it. I put over 80,0000 more miles on the engine, before it got torn down and went into the old FJ40
