Seafoam--can't believe what it did to my engine!!--Episode 4--Compression Test

I want to see if seafoam makes a difference regarding compression well it actually increased the compression or will it hurt the compression by cleaning up the cylinder walls and the pistons the piston and the valves so what I have beside me is an edger that I bought about 25 years ago and I've used this edger a lot I used to have a lawn business when I was in college and I would use this every Saturday and sometimes week nights quite a bit so this engine has a lot of wear it's 25 years old so this will be the perfect machine to test off test on I know there's a lot of carbon in this engine I don't even want to bother taking the the engine apart to look at it because I can just look inside the spark plug hole and see if there's carbon in it and like I said 25 years old so we know there's a lot of carbon inside this engine so what I want to do is run a quick compression test on it when it's cold and they're going to run a compression test on it after the seafoam when it's cold so I'm going to go ahead and thread this in okay we got a really good seal there it's what I'm going to do is I'm going to record what the compression is with each pole okay we're up to about 35 pounds pressure up to 70 up to 80 up to almost 90 looks like we finally got to about ninety two point five okay so I'm going to let the pressure out okay so I just finished writing this engine for about 20 minutes it's about as warm as it's going to get so it's pretty hot engine so I'm going to go ahead and remove the spark plug and we're going to do a compression test again I have not added seafoam yet we're going to get a warm compression see what we got okay this is the first poll in this act worried about looks like about a little over fifty pounds the second second poll looks like we are up to about eighty pound and the third pool looks likely right around 90 fourth pull looks like of about ninety six looks like we're right around 100 pounds pressure so that's about as good as we're going to get okay it's the engines still warm we did the compression test so now I'm going to go ahead and run eight ounces of seafoam through the engine [Applause] [Music] [Music] [Applause] okay I'm go ahead and hot soak the engine for about 20 minutes and then start it back in about 20 minutes since I hot soak the engine so I'm going to go ahead and see if I can get this thing to start [Applause] [Applause] [Applause] okay I just finished running the engine after hot soaking it for about about 10 minutes to get a nice and warm so what I'm going to go ahead and do now is take this apart looks like the pistons pretty much at top dead center I'll try get it hold it pretty close now let's put the spark plug back in hopefully allowing sort of steam or vapor to stay contained okay it's been about 20 minutes so I'm going to go ahead and remove the spark plug and try to remove some of the excess fluid so this is probably going to go everywhere but all right that should be pretty good all right i'ma go outside and start this up and run it for a few minutes and then run a test on it [Applause] [Applause] [Music] you [Music] [Music] [Music] [Applause] [Music] okay the engine is still hot and we've just finished running it for about 15 minutes so I'm going to go ahead and run another compression test second surprise success and this one adapter hot soaking is the engine it's dumping the whole bunch of seafoam NCS into the spark plug hole all right right the first pull got us up to about 65 pounds now we're up to 90 pounds and a second pull RUP two other pounds and it looks like we're at about a hundred and five pounds yes looks like this is how I'm going to get about 105 pounds of pressure okay so it seems to me that it built it built pressure a little bit faster than before so the next test is going to be letting this engine cool and then seeing how it has super what kind of pressure - when it's cool so I'm just going to go ahead and drain off his pressure now and actually is going to take a while so it'll be a while in order for this engine to reach room temperature so I'm going to go ahead and just leave everything connected and we'll be back a little bit to test out the compression okay so the engine has had a chance to cool off it's totally cool cool to the touch so now why I'm going to do is pull on this about try to spin this over engine over about five times and I run a compression test and see if there's any difference before seafoam versus after seafoam with the cold engine compression test okay that's what about 40 psi that's what about 80 looks like that's about 95 and looks like it's a little over 100 pounds pressure okay so the verdict is there it looks like the compression test did improve so apparently like I said before this is a 25 year old tool for me been using for many years I've always taken good care of it but I'm sure there was some carbon buildup this removal of carbon I think around the Rings and valves must have caused the compression to improve this is a really fun video but I am really excited about the next video a lot of you suggested we use water so that's exactly what we're going to do in the next video we're going to use water and we're going to compare seafoam to water which one cleans the combustion chamber better I would love to hear your comments I love for us to take a boat and see how many people are voting for water and how many people are voting for see pump also do you think it's going to hurt the compression we're going to test that out some of you have suggested that water will potentially cause harm to the cylinder wall so we're going to find out if they answer that as well but once again thank you very much for watching the videos and I hope you'll consider subscribing thank you [Music]
