looked at the seafoam, saw that it is nothing special
so took a woods buggy (full sized bronco) and just did a test.
also had a subaru loyale woods buggy (I have about 6 trashed cars
I use for hauling wood and stuff at my cabin)
got nothing better to do.
seafoam vs home brew.
seafoam can sucked in via pcv valve and small funnel
same with the homebrew. all cars have a pcv valve so this type
of draw was consistent if the engines weren't.
raw exhaust on both with a stainless steel screen
-----
homebrew is a solution of 20% raw naptha, 40% distilled water, 40% 97% isopropyl alcohol
seafoam is seafoam
so anyway I used my homebrew and sucked it into the bronco and boy did it want to die. in fact it did and I started it back up after a lot of trying and a jump, but she started again and I finished adding the homebrew till it died and let it sit
then i go and seafoam the subaru same way
---
start each back up and let them run, then stopped them.
then i pulled the heads (I have 2 engine lifts and bays so this is no big deal, and isnce
these engines are mounted in open engine bays just barely attached, they come out quick.
first of all the homebrew basically steam cleaned the pistons. some big chunks of carbon were gone. some remained. it looked ok. could use homebrew maybe 2 more times and I think it would steam clean the rest right out. some flakes of carbon ended up in the screen, and a lot of black soot came out, along with gobs of steam
looking at the subaru...seafoam...it didn't have any chunks of carbon missing from the heads. didn't look like it did much. it did smoke a ton and nothing was in the screen.
my redneck analysis: seafoam might clean injectors but it is nothing super special to your heads or carbon buildup. water and alcohol does as good a job or better.
I would NOT put either one in the gas tank or engine oil. that is just nuts. seafoam doesn't have any friction modifiers.
but as a top end cleaner...paint thinner, alcohol, and water wins. I nalways knew anyway that the true way to clean your top end is to
pull engine apart and steam the hell out of it then lube and reassemble. tune-ups in a can can work but they cannot fully restore like
a good old steam clean.
so if I had no choice I guess seafoam is OK but it ain't no bg44k that is for sure.
