PDQ!! Seafoam question......new plugs before, or new plugs after???
Hi.
As some of you may know, I sucked in water while on a wheelin trip last week. Anyway...I got her running pretty much right, just to be sure I want to sea foam it and swap the plugs.
Do I seafoam it with the old plugs still in it, then swap to new plugs??
Or do I swap in new plugs, then seafoam it??
I've got a couple more hours of sunlight...and I wanna do it tonight.
Thanks.
Shane

If the tranmission proves to be too mcuh trouble I would suggest taking it to reliable transmission in Aloha. It is on the SW corner of TV Highway and 170th. Jim did the transgo shift kit and larger tranny cooler in my truck. He comes highly recommended by those that have used him.

My old plugs were fine after I Seafoamed. I went ahead and changed them because I had bought new ones already. I believe that it's recommended to change oil afterwards. Something about it possibly washing past the rings. Here is the Ford article shamelessly stolen from another forum. I just noticed this applies to the ohv engine, not sure if any different for ohc engine.

^ ENGINE - 4.0L OHV - CARBON KNOCK ON ACCELERATION
^ NOISE - CARBON KNOCK ON ACCELERATION - VEHICLES EQUIPPED WITH 4.0L OHV ENGINE ONLY
FORD:
1990-1997 AEROSTAR
1990-2000 EXPLORER, RANGER
ISSUE
Some vehicles equipped with the 4.0L OHV engine may exhibit an engine noise which may be perceived by the customer as a piston/connecting rod bearing knock. This carbon knock is heard only under load during the drive cycle. Carbon knock is a customer drive duty-cycle phenomenon that cannot be repaired with an engine exchange. This may be caused by carbon build-up within the combustion chamber.
ACTION
Verify condition. If normal diagnostics fail to correct the condition, de-carbon the combustion chamber to help quiet the carbon knock noise. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Use Motorcraft Carburetor Tune-up Cleaner PM-3.
2. Carbon removal:
a. Disconnect canister purge line from throttle body.
b. Attach a vacuum line to the canister purge port.
c. At hot engine idle, allow the engine to ingest 1/2 to 2/3 of a can of Motorcraft Carburetor Tune-up Cleaner. Use caution not to ingest too quickly due to potential hydro-lock issues.
d Shut engine off and allow it to soak for one hour.
e. Start engine, allow engine to ingest the remainder of the Motorcraft Carburetor Tune-up Gleaner.
f. Remove vacuum line and re-install canister purge line.
g. Road test vehicle at 3500 RPM for 2-3 miles.
h. Repeat above procedure two times for a total of three times.
i. Change oil and filter.
3. Review the customers' driving habits. The recommended drive cycle should include daily periods of engine operation above 3,000 RPM, such as a brisk acceleration from a stop position. This will break/burn the carbon off the piston head.
4. Use regular unleaded fuel, 87 Octane. Mid-grade and Premium fuels may increase the probability of carbon buildup, leading to a knock noise.
