Default Seafoamed Today -- Smoke from area around coil

Hi All,

I did a seafoam treatment today by sucking in through the PCV hose. Have done it many times before on many vehicles, and know to expect white smoke from the tailpipe.

But today I see something strange ... there was white smoke from the engine compartment. I figured it was an exhaust leak, but it wasn't coming from the exhaust, it seemed to be coming from the valve cover area around the coil pack.

I have been trying to track down an oil leak on this car as well, from the rear of the engine.

I am thinking the valve cover may be cracked, and that is why I saw the smoke today and probably where the oil leak is al.

Anyone have any other ideas?

Your guess sounds good since the rear of the valve cover ends right where the coil is. You can try taking the coil off and see if the rear bolts for the valve cover are tightened to spec. 105 in lbs.

it is probably just smoke lingering around by the coil(not coming from anywhere around it). every time i seafoam a car, i see smoke come from the engine compartment. it is more than likely coming from the flex pipe or an insignificantly small exhaust leak. i would not worry about it at all. it's completely normal. i usually use half a can at a time through the PCV hose, and in my experience, seafoam always causes smoke from strange places.

What's this Seafoam thing? I've never heard of it being sucked in through the PCV. Do you dilute the Sea Foam or using it straight? Is this done to free up the carbon in the engine? What's the procedure?

Inquiring minds want to know.
