Right now I have 2 pint of Seafoam and one can of Deep Creep. I was wondering what were the proper methods for using this on a TPI engine.

Will it hurt the O2 sensor?

Thank you

it is o2 safe

pull the vacum hose off of the brake booster and pore it in per the instructions on the bottle

after you stalll it and let it sit a bit then re start it

take it out on the highway and blow out all the sh*t

easy and fun to smoke out your block

LOL

I was wanting to put this in the crankcase and fuel tank also. But I just got to thinking if I use the Deep Creep to spray into the throttle body then I should not have to put the other stuff in the Vac line. Right? Or is the DC just for cleaning the plenem/runners?

Also, When should I do an oil change after putting this stuff in the oil? Could the gunk it's cleaning out clog up my oil pump?

do not put it in the oil it will do nothing but thin the oil

and dont put it in the fuel that will cause problems just put some fuel system cleaner in

if you want put some engine flush in then change the oil

if the deep creep is a spray then take the air intake tube off and unplug the maf. start the car and spray it into the tb and rev it up and let it back down till the bottle is empty

just put the seafoam in the vac line per the instructions

What will it do I have never heard of it causing probs? So will just putting in the vac line help out alot? Last question, is the DC doing the same thing?

i never heard for DC really but if it is a spray it will clean the upper intake

the seafoam is more for the lower intake and the valves and combustion chamber

i dont know if it will really cause problems int he fuel but why not just put some fuel system cleaner in

it will work better then the seafoam thats for sure

its not ment for that

OK I see.

Does it clean the back of the valves or just the face? I assuming just the face.

i think both

cool b/c thats the main thing I wanted to get clean. That and my pistons.

Thanks for the info.

welcome

i just used it in my car last week but i used the gm version(top engine cleaner) and i had a huge cloud of carbon

LOL

Did you notice any difference in performance?

a lil but my car has more problems then just that so haha
