I seafoamed my engine last week, and changed the only that last weekend, just a coincidence.

I noticed a few things, first, my truck idles lower now, too low if you ask me, around 450 when its warm.

Also, I am STILL putting out smoke, a week and a half later. Not nearly as bad as when I seafoamed it, but before that, the truck didn't smoke AT ALL. Now, it does, (white smoke).

Why? did I hurt some of the seals in the valve train or something?

It could loosen something that was sealed with gunk before, allowing it to now flow. "Smoke" being white is not a problem, unless it is a billowing type and truly is smoke. During these cold days, you can have whiteness coming out of the tailpipe, even after warm-up. My truck idles around 500 rpms and sounds fine. Could try really blowing it out. Floor it a few times, after warm up. Vehicles need a little WOT every now and again.

It's always a good idea to change the spark plugs after Seafoaming a vehicle.

If the first time on an older vehicle, yeah. Also good to change the oil with the next 100 miles or so.
I know some people have added some to the engine oil a few miles before changing it...i never have, though.

I'm gonna pull the plugs tonight and inspect them, to make sure that they look ok. I changed the oil three days after the 'foaming. I guess that if the plugs look ok, I'll stop acting like a princess, give myself a nut check, and stop worrying.

I know its not really possible, but I was concerned about the temperature change in the head causing it to warp, and now I have a coolant leak.(already have a small leak, but I can see it on the bottom of the motor, not worried about it going into the motor until now)

Thanks for the input.

I've been thinking about trying the seafoam on the hoe. Do I just go to a local auto store get some and pour it into a vaccum line?

yup... do it slowly while its running... it should stumble a little then when you get towards half th ecan, just dump it in there quick. it may stall -which is good, otherwise shut it down and let it sit for 20mins or so.
then drive the piss out of it

the vaccum from the brake booster line feeds off of the back of the manafold

I've never had any issues using Seafoam on any of my vehicles. I did see some sparkplug fouling, but the plugs had around 100k on them.

I've basically tried to damage a vehicle with Seafoam (a 2000 Ford CVPI with 135k miles) just to see what would happen. I've ran an ENTIRE can in the crankcase for 3k+ miles several times, sucked up TWO can through the booster line, and ran a can in EVERY tank of gas for probably 10 tanks. Only thing I could tell was that it cleaned the HELL out of the tops of the heads (I.E. all I could see through the oil fill). Did it necessarily fix anything? Not really, throttle response is better, but it still has a lot of lifter noise/spark knock.
