Seafoam issue...

Hey guys,
Today I was seafoaming my jeep for the first time and I noticed smoke coming from not only the exhaust but also the engine bay.
Is this normal?
I used the brake booster vaccum line.

It will produce A LOT of smoke if done right

Like from cracks in your exhaust? Your exhaust manifolds are probably cracked and letting the smoke out. I can't see where else the smoke could be coming from.

So, is it normal, not really but pretty common on this jeep/engine.

Alright thanks guys.
I probably had as much smoke exiting the engine bay as I had coming out of my exhaust end.
I'm happy with the results though. It seems more responsive and a tad bit quicker.

Smoke from the engine bay has happened on all the JK's we have done the seafoam from 20,000 miles and up at our wrenching party's.

Hmm.
Well I'm at 117,000 miles.
And today I had a new issue come up.
When starting the jeep this morning it seemed to struggle more then often and it took longer to start.
Usually my jeep starts up instantly but after sea foaming it takes a few more seconds to start.
Do you guys think the jeep is tuned to the dirty engine and just needs to be reset?
Sorry I'm still kinda new to this stuff

Maybe you have a coincidentally occurring weak battery. It will slow down starting.

Might have fouled up the spark plugs.

Nope. Brand new optima yellow top battery.
And I did not use it in the oil.
If you try starting it hot it seems weak.
The spark plugs might be bad.
Anyone have issues with seafoam and spark plugs?

How old are the plugs and wires? They really don't last too long. My first set was done at about 50k.

How did you sea foam the Jeep? Through a vacuum line or the gas tank?

Vacuum line for the main part and a little in the gas tank is ok too I heard. But quote me if I'm wrong.

What he said ^^^
As for the plugs I really don't know haha.
I'm at 117,000 miles so I think the dealership replaced them at 100,000 or something.
