also does anybody recommend a specific brand of oil... valvoline, quaker state, penzoil, castrol etc.

 

look at my last post, you put the seafoam through the fuel pressure regulator vacum line.
post a good pic of your motor and ill circle and label everything for ya.

 

IMO i recommend castrol full synthetic. been using it n all my cars and never had problems. i use castrol 10w40 full synthetic oil on my 95 civic ex... and ur pcv valve is on the top part of ur intake manifold by the injectors.

 

ok all the people i talk to said only put sea foam in the oil cranks case if your going to change it in the next 50 or so miles because if you have like oil gunk it will clean it out and thick in your oil. but on the can it says its fine. i dont now.

 

well im going to change the oil anyway its been 3000 since my last one. my civic takes 10w30 so what the difference between full synthetic and non synthetic oil? also if the guy who owned my car previously was using synthetic and i change it with conventional would that be a problem?

 

after putting the sea foam in the oil run the car for about 50 miles then change it and you should be good.
