So I've done the seafoam in the gas trick, and I can't really see a great improvement. My mechanic has told me that I have a carbon build up issue and thats why my EGR valve keeps going up, and the check engine light stays on. I really don't want to pay to have my engine ripped apart and soda blasted, can anyone give a guy a little advice on seafoamin his engine via brake booster ? Whats the best way to go about this with my car, if it's even worthwhile?
sea foam?????, never heard of it??? hmmm, dose your car use oil, 9 times outa 10 your egr vale is sticking is becouse of the engine burning oil, also check your pcv valve, oil blow by is bad... you could also try bruning better fule for a while "yes I know it's expensive" but often time that'll btreak up any build up and get it uota there, "burns cleaner" hope this helps...
I use sea foam everytime i change my oil and really do think it does a great job. just follow the instructions on the back of the can. u can insert it through the intake side of the pcv hose and make sure u dont stick the tube fully in there because it will bog down the engine when it sucks it in. u can also u is in your gas and oil. hope this helps
