Did Seafoam cause this?

Per their MSDS, it is pale oil, which is a light oil, naptha, and alcohol. If you could find alcohol that is pure for sale, it would be easy to make yourself. Most OTC alcohol contains water so most likely you would end up with a gooey mess. This is one of those products that folks swear by but when you look at the formulation there is nothing there of benefit. I can only imagine the damage to cats and sensors from running this stuff thru the engine but if you use it and have good results from it- keep on doing it.

Whilst it seems you guys are 90% of the way there, I feel the need to add the 10%
For the record, I agree, especially in the discussed application, liquids CAN be considered incompressible, and thanks to the bright spark who explained pressure washers....to add to that, not only would the water decompress, it'd probably vapourise.
OK. WHen you are sucking your Seafoam through your vacuum line, you are adding lots of air. Seafoam in turn atomises. Seafoam is combustible. It combusts in the cylinder as it enters. (I don't recall reading on the can it saying let it stand, but that may make sense, if some residue remained, to further clean, although I guess if you're using brake line, you're not hitting the throttle body are you?)
Therefore, you don't have an issue with compressing liquids in the cylinder, which anybody who had the 'special' engine with the leaky gaskets, would know, adding significant water/liquid into a cylinder has disasterous results.
My personal results with Seafoam have been encouraging, I bought my '92 a few months ago and it had sat more or less idle for some time. Got lots of check engine codes which eventually went with replacement of the O2 sensor, but tried injector cleaner, no improvement, tried Seafoam, did notice improvement overall. Just need to manually clean tb I think, but have noticed the thing runs better. Being used is part of it.
Seafoam will also absorb water, so is good for cleaning crap, water etc out of fuel tank. Would imagine changing fuel filter after Seafoam's a good idea.

IMO.. a 50 shot DPI of nitrous is the safest and best way to clean the engine out
not only will u see an improvement in mpg but also see a great increase in performance
