got my seafoam maintenance today , i did it first time , car has 56.500 miles on it, is an 01 2.8 q, a lot of smoke.... but before that , guess what? the vacum nipple was cloged, i didn`t have any engine light on or anything suspecious, car drives good and i was surprise that i don`t have any vaccum on that line to suck the seafoam inside. so i toke everything apart and remove and clen the suction pump with carb cleaner for at least 20 minutes with spray from both sides.... also i got the vacum line replace with heater hose and works fine so far.

i did some homework and this is what i found related with suction pump :"The breather pump valve that sits under the Y-Pipe gets clogged, which increases the crankase breather pressure to the point that it blows out the seals." i guess i was lucky to find this in time.... at dealer should be around 30$ only the suction pump.

replacement is easy, it has 3 hoses to be pulled of. to locate the pump - from the break booster goes a hose into the engine bay where it connects the pump.
