1996 Lincoln Mark VIII Seafoam Treatment
I seafoamed my 1996 Lincoln Mark VIII today. I haven't done it in a while
and it shows. There was a lot of smoke this time. The white '97 Mark VIII
LSC next to it is much cleaner. The last time I seafoamed it, there was
very little smoke. According to the descriptions on the can, Seafoam is
supposed to break up carbon deposits and clean the induction system,
valves, tops of pistons, etc. It is also supposed to get rid of the rotten
egg smell associated with clogged catalytic converters. Fortunately, my
cats are still in pretty good shape. I don't know if Seafoam really works,
but I know my engine runs smoother after a treatment. And it sure is fun to
Note: Eventually, I'm going to make a more detailed step-by-step video with
someone else holding the camera. This was obviously done very quickly. Next
time, I plan to use 3 bottles. One for the crankcase, one for the intake,
and one for the gas tank. Now, you've got to remember to change your oil
IMMEDIATELY after seafoaming your crankcase. Or else the stuff will destroy
your seals and gaskets. Running it through the oil is like high performance
Motor Flush. It cleans the crap outta your engine block.
The Mustang Cobra Has A Mark VIII Engine
Contrary to popular myth, the Lincoln Mark VIII does not have a Cobra
engine in it. In fact, it's the other way around. The Mark VIII got the
4.6L DOHC aluminum V-8 in 1993. The Cobra didn't get it until 1996.
Therefore the Cobra actually has a version of the Mark VIII's engine.
