latinopikachu Posted April 19, 2006 Report Share Posted April 19, 2006 1. What is it for? Originally answered by: J-allan, Jan 21 2006, 09:07 PM Cleaning out the carbon deposits and whatnot in the top half, as well as possibly quieting lifter noise or valve tap. (if you use it through the pcv hose or brake booster line) If used in the crankcase right before an oil change (100-150 miles before, per engine guru Renboy), it will help remove sludge and varnish in the lower half of the engine. Users report a smoother, quieter engine, with possible increases in fuel economy. 2. How do I use it? Originally answered by: J-allan, Jan 21 2006, 09:21 PM Well, if you want to do it through your pcv hose or brake booster line, use about three ounces in a cup, and make sure you only 'sip' the seafoam from the cup with the hose, do not immerse the hose end completely into it. When you disconnect the pcv line, the engine might want to die out. You may have to keep the rpms at about 2000 when you do this. In the crankcase, just pour the contents in and drive the car for about 100-150 miles, then change the oil. Seafoam is the brand name, I don't know if they make a generic substitute.

enginph Posted March 18, 2007 Report Share Posted March 18, 2007 Can anyone tell me where this pcv hose is? I dont wanna suck it into say oil:) Picture would be great actually. I ll post one when sure.. 1. What is it for?

Renboy Posted March 19, 2007 Report Share Posted March 19, 2007 To add to lat's post, the pcv hose comming off the front valve cover is short, so you'll have to do some maneuvering to get it properly. Or extend the hose with a brass barbed connector. And warm up the engine before you do this, don't do it on a cold engine. Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted March 19, 2007 Report Share Posted March 19, 2007 u shouldnt be able to do ANYTHING on a cold engine. nonetheless, thanks for the thread...im not sure if i wanna do seafoam as my car has alot of miles on it. but then again, it has proved itself to be a great motor with minimal problems. maybe seafoam will further extend its lifetime? (i have to beat this 530,000 mile millenia!) Quote Link to comment Share on other sites More sharing options...

Frankzao Posted March 20, 2007 Report Share Posted March 20, 2007 At what intervals do you recommend this? And at how many miles would you start? Also "3 ounces per cup"? Do you mean 3oz per cup of oil? The hose on the PCV valve will suck it into the engine? This is better than just adding it to the oil? What about the other side? Just questions.....

Renboy Posted March 20, 2007 Report Share Posted March 20, 2007 Honestly, don't bother with the pcv thing, toss 1/3 of the can in the oil, and the rest in the gas. Do it before every oil change and you should be good. Quote Link to comment Share on other sites More sharing options...

enginph Posted March 20, 2007 Report Share Posted March 20, 2007 Why did you say that now?? Will it be the same in oil?

Renboy Posted March 21, 2007 Report Share Posted March 21, 2007 The reason you feed it through the pcv is so that it cleans the intake manifold and combustion chamber. Though this process can damage your engine (small chance, but still a chance), and with the pcv and egr venting into the intake manifold it gets pretty dirty, fairly quickly, so this won't help much. The consequence outweighs the benefit IMO. You'd be better off putting more in your gas which will safely have the same effect on the combustion chamber, and every once in a while remove the intake manifold, toss it in degreaser for the night and put back shiney and new.

enginph Posted March 21, 2007 Report Share Posted March 21, 2007 I thought it cleans the valves and lifters when applied from pcv? How hard it is to remove intake manifold?

mohamedeladawy@hotmail.com Posted March 21, 2007 Report Share Posted March 21, 2007 the intake manifold is that reallllly silvery thing right above the front intercooler. thats the front anyway. the rear one is that same shiny silvery thing in the back. looks like a fat log of silver. ren...can i use this seafoam? i was advisd not to cuz of my mileage but i mean..everyone keeps saying that and my car runs better than most millenias Quote Link to comment Share on other sites More sharing options...
enginph Posted March 21, 2007 Report Share Posted March 21, 2007 It seems to me impossible to take out Ren did you mean we can hydrolock with seafoam? Or something else? I plan to put 2-3 hoses to PCV and use one to sip seafoam others to take in air. the intake manifold is that reallllly silvery thing right above the front intercooler. thats the front anyway. the rear one is that same shiny silvery thing in the back. looks like a fat log of silver. ren...can i use this seafoam? i was advisd not to cuz of my mileage but i mean..everyone keeps saying that and my car runs better than most millenias Quote Link to comment Share on other sites More sharing options...
Renboy Posted March 21, 2007 Report Share Posted March 21, 2007 I did indeed mean you can hydrolock. Camel, if it's broke, don't fix it. Given the mileage the seals are probably old oil, rather than oil seals in your car. I would say use at your own risk. Lift the oil cap and look inside, is it all black and shitty, or nice and clean? If it's black and shitty, then I wouldn't risk it. Quote Link to comment Share on other sites More sharing options...

mohamedeladawy@hotmail.com Posted March 21, 2007 Report Share Posted March 21, 2007 its actually very clean and slightly brown. Quote Link to comment Share on other sites More sharing options...
Renboy Posted March 21, 2007 Report Share Posted March 21, 2007 Oh, and you'll clean the lifters with it in the oil, not intake/pcv. The seats you'll clean with it in the gas, so putting it through the pcv is just to clean the manifold(s). And even at that, it still won't clean them well. The shit inside the manifolds is basically baked on. But if you toss in degreaser, they sparkle how clean they come out. When I had my manifold powdercoated the inside looked like the manifold had just been cast because the pc place let it soak overnight in degreaser.

enginph Posted March 22, 2007 Report Share Posted March 22, 2007 Why to clean the manifold then. It looks pretty big, it will just make a path to air. So even if there are some crap it wont affect that much right? I thought PCV stuff would clean the lifters, valves (noise).. How hard it is to remove?

Renboy Posted March 22, 2007 Report Share Posted March 22, 2007 Any degreaser should work, it's about $20/gallon and can be thinned. Removal depends on engine. The 2.3 is quite laboursome to remove, in all respects, it's a pita the first time. The 2.5 is easy to remove. You clean the manifold for the same reason people port/polish heads, to increase airflow, and for smoother airflow. Not only do the ports in the intake get smaller as shit builds up, that shit causes disturbances in airflow. Cleaning that crap out minimizes the disturbances and gives you the opportunity to port match the intake manifold to the head, to further minimize disturbance. Don't expect much, but anything is better than nothing. Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted March 22, 2007 Report Share Posted March 22, 2007 haven't actually used seafoam before, go back and forth on it, for some people it seems to create problems Quote Link to comment Share on other sites More sharing options...
mohamedeladawy@hotmail.com Posted March 22, 2007 Report Share Posted March 22, 2007 i think it depends on the severity of the engine. if its too gunked up and gaskets have been replaced by shit...then yaa itll create problems. im still thinking about mine.

enginph Posted March 22, 2007 Report Share Posted March 22, 2007 I put 3/8 pint to half tank. Kind of smoother or nothing happened. I aimed to clean the injectors and the vapour inside the tank. No problem at least. And since Ren told it will clean the chamber as well, I will add it to couple more fillups. How many would do the job? i think it depends on the severity of the engine. if its too gunked up and gaskets have been replaced by shit...then yaa itll create problems. im still thinking about mine.
