Seafoam for 2009?
 

I looked at the seamfoam DIY in series 1 and it says that where you put the seafoam in pre 09 rx8s has been removed in 09s. So how would you go about doing this, is it even possible still?

I did a search of just "seafoam" in the whole series 2 forum titles only and nothing came up. A search of all posts in series 2 showed some people suggesting seafoaming but nobody ever said how to do it in an 09.

The reason I ask is because I dont wanna just go hunting through the engine bay and find something I think is correct, I would rather be told where to do it at. I have had no problems doing this with other cars I had but I really dont wanna break anything on this one, lol.

The nipples are gone?

question is, how many miles does your car have? is doing a seafoaming at this point even necessary?

I dont really know why, but I just bursted out laughing in my cube when i saw this .... lmao


there is nothing else said in your response except "the nipples are gone [question mark]" haha, i dont nkow, made me laugh, a lot

Almost 25k, on my other cars I usually seafoamed every 20k or so. Since this one has more problems with carbon than others I've owned I figured it would need it even more.

Yes, according to the DIY the nipples are indeed gone. I also just went and checked myself, I couldnt find them.

I really want to make a smart ass comment but I will hold back.

No, you don't need to seafoam your car. 20k is no where near close to enough to make this justifiable. Clean your plugs and call it a day...

you could probably use one of the vaccum hoses after your MAF in your intake? Have someone back me up on this before you do it tho ... how did you do in on your rx7s?

isnt there two hoses on the lower manifold?

Theres no smart ass comment to be made anyway. Believe it or not, I own this car. If I wanted to spend $6 to do some cleaning, then I very well could. I was not asking if I should I was asking if it was possible. From what others have said and I have seen, its not possible to follow the old DIY so i wont bother, for now. Until I find out how.

I bought this car used with 21k miles on it, for all I know the person who owned it before me didnt rev high very often and it may be dirty in there, its hard to say. I have a friend who bought a rx8 and killed the engine just under 20k because his wife drove it more and she never went past 4 or 5k rpms. Thats what mazda told him, anyway.

i looked down where the nipples were on the older ones and didnt see anything. This was with a flashlight at night though so I may have missed the hoses. I did read in the DIY it said the nipples were replaced by hoses on 2006+ but then it also stated that series 2 was missing the nipples and they didnt know how to do it. So I guess I will just have to wait until someone posts that has done it, because the DIY is confusing in the way it words 2006+ and series 2.

I think it's good idea to seafoam it now and 20 should be fine if not before. Why wait till it cakes up so much chunks fall off into cat? If there is a hose on the nipple probable can just remove hose and put the seafoam into the intake nipple (not the hose end of course).

I believe the S2 has a tube on the filler neck that splits into two hoses that go down to the lower intake manifold, you can try that one. should be the top hose on the filler neck. the lower one some how goes to the intake tube which is why if you over fill the engine oil, you still can have oil in the intake tube.

Call me stupid but the filler neck would be the main tube coming back from the air filter housing, and there is one hose directly on top of this tube? Correct me if I'm wrong please

2007 rx8 seafoam
 

I have a 2007 rx8 but I am missing the nipples that are shown in the DIYs too :wallbash:. Is there anyone out there that can help me out with this please? my car has almost 70k on it so its about time!

I performed the Seafoam in my 2009 R3 (RHD) today...

The same sensor connectors were removed, including the e-shaft position sensor (simply pushed the air-box to pop it up and to 1 side for access).

Both of the nipples are definitely present.
There is an extra sensor mounted on the Secondary Air Pump, which makes access more awkward.
However, both nipples are already in use with some pipes connected.
Both pipes are connected via a t-piece to a larger pipe which then is connected to the top of the Oil filler.
This is the same modification made to later model S1s (was present on my friend's Kuro).

After some deliberation, we decided that disconnecting the pipe from the oil-filler, and using that to feed the Seafoam would be easier and just as effective, and as a bonus feed both rotors at the same time.

We considered this a bonus - effectively less cranking whilst administering the seafoam == less time cranking without effective rotor lubrication!

So - we did a measured 8oz this way - and hoping that it was evenly distributed to both rotors.

The whole 8oz was used by with 2x 5 second cranks of the motor; a whole bottle would have been gone with any more cranking!

After smoking out the neighbourhood (chose a friends place instead of mine! ;-) )...

The engine now feels much smoother and feels like it pulls harder in general; and the idle is less lumpy. I hope it's not just a placebo effect!

FYI - the reason I administered is because I got a "below spec" reading on all rotors .. and a 4.6 on one chamber of the rear! The lumpy idle was the only outwardly noticeable symptom of the low compression... Though now I feel there was perhaps a power loss in general as well... And MPG was on a slight "downward" trend... (15-16MPG instead of 17-18MPG on average).

Just curious - what were your exact compression #'s?

this helps a lot! i was nervous to do it to my car without hearing from someone that already did it. thanks! u just helped out a whole lot of people. will try this out and post for the results so it can help others as well!
