The other day I was going to put Seafoam in my tank and went to look for the special funnel that is used in emergency situations and couldn't find it. Is it provided by Ford or do I have to buy one? I looked all around the trunk and no luck. Also, has anyone Seafoamed their Coyote? There appears to be no vacuum tube available without taking of engine cover. Doing it to clean throttle body because of members mentioning them being dirty due to oil consumption.
How do you anticipate adding seafoam to the tank will clean your throttle body since the only way into the engine would be via the injectors, downstream of the TB? Even the vac tube method wouldn't help you since there's pressure upstream of the TB and vacuum only after it.
Clean the TB, if you insist, with some good old-fashioned carb clean sprayed into it. Even if the car consumed some oil, the TB would have to be coated in 1/4" of residue before you'd see performance impacted much.
I anticipated on doing the vacuum line method but didn't want to take engine cover off. That's when I decided to put it in my tank. I know it won't clean tb when ran through the tank. That is why I asked question on the emergency funnel. Because of container they put seafoam in its impossible to hold trap door open with screwdriver and pour the seafoam in tank. It will run out the bottom of trap door isn't open. I've used carb cleaner before with a bad experience. It cleaned tb but the crap that came off fouled something in lower intake resulting in a trip to Toyota dealer.
it appears you're just remembering a valuable lesson. Cleaning TBs isn't necessary unless their so occluded they are preventing full closure of the throttle plate. look elsewhere for something to do. And don't pour Seafoam in the crankcase if you arrive at that idea.
If you insist, you can have the TB off in about 15 minutes. removing the engine cover is even easier; just tug it off.
I have a small funnel with a long spout I use for motorcycle oil changes. I got it at a local auto shop eons ago but, that suggests they are still out there.
