Hey guys , I just tried the "Seafoaming" as i was injecting the sea foam i realized that it was leaking onto the ground after i did the front upper intake manifold nipple. My problem is at high rpms a bucking or a hesitation issue. i havent recieved any codes recently so im very curious here. it sounds almost like an f1 car at high rpms.

LBrown8

Bump please help

LBrown8

I was recently Seafoaming the eight when I notices that the sea foam was dripping onto the floor , I injected into the rear and front intake manifold nipples as instructed. My issue is my car is hesitating at high rpms and makes a slight gurgling noise or even sounds like an f1 car. I am thinking my ssv is the culprit here but why would the sea foam leak onto the floor? I also only have a pending code p0420

LBrown8

Sorry , I have a
Turboxs exhaust with race pipe so most likely why I am recieving this code I also have a arm cai.
Any idea for the high stutter at 7k? Car has 1

Seafoaming trashes your plugs. It is recommended that you replace your plugs immediately after seafoaming.

That CAI could easily be causing the problems too. Most aftermarket intakes cause a power loss. Only a handful of known ones don't ad I don't recognize that brand.

thanks for the heads up, I have a set in transit, the issue is still lingering here though. Which is at high rpms my car seems to gurgle or even buck to some extent, car runs flawlessly idles perfect starts without a hitch doesnt over heat, burns the right amount of oil. and doesnt throw codes.
The codes that have been thrown have been P0300 P0410, a miss fire and im not sure on the other. I checked for vacuum leaks and i didnt find any, but like i said when i injected seafoam into the car the sea foam actually leaked onto the ground via something im not sure of, if someone can explain to me what caused this leak and where is the exit point. Or if someone has any idea what could be wrong with my car. I thought my SSV could be stuck open or working but just not working as good as it should. which would cause a power loss?? please help

LBrown8

My problem is my car is stuttering or bubbling at high rpms around 7k+ its annoying as hell when your car will not run perfect, when everything seems perfect. I have no CELS i had a cell in the past p0300 and p0410 but ever since i put my exhaust on i have not seen those codes. My car Idles fine sounds fine burns oil normally everything works flawlessly besides the A/C and this slight power issue. Here is a video of me reving the car and you can hear the bubbling/ hesitation at 7k
please someone have an answer for this, My thoughts are to do with the SSV and maybe its stuck? but wouldnt i receive a code? and another thought is maybe its the fuel sock being dirty? but again would these issues cause such effect?
I have an 04GT mt
104000km
engine was replaced at 99,883 km
I have a AEM Cai
Turboxs Full exhaust (w racepipe)
plugs wires coils all done at 10100kms
coolant transmission and oil changed all at 104k
Seafoamed yesterday.

I appologize for being a forum ***** but as soon as my question is answered i do not need to keep posting

LBrown8

Also, While i was seafoaming , the seamfoam was injected into my front upper intake nipple and ended up under the car right next to the oil pan

Ignition problems will typically manifest at high RPM first. Seafoam fouling your plugs is a version of "ignition problems". This isn't abnormal and should be fixed with the new plugs.


As far as the seafoam leak, it depends on where it leaked FROM. You haven't told us that part.

If it's leaking from...
- your oil pan, there is serious problems
- your exhaust tips, it's normal
- your header, you have an exhaust leak
- your side mirrors, you were probably applying seafoam wrong
- your ***, you were definitely applying seafoam wrong






Detail how you seafoamed, as there are a few methods, and WHERE it's leaking from.

Otherwise, just wait for the new plugs and check the high RPM stumble then.

+1 on the Ignition issue ... new plugs

I have an embarrassing story that I probably shouldn't telling you RIWWP but it looks like this poor guy needs some moral support, and it may help.

I did the seafoam thing using the lower in intake nipples ... all went well.
Went for a beer while the seafoam sat for a couple hours.

When I came back ... there was a small pool of seafoam on the ground (translates to Newfie as Floor )

It leaked out my from my Spark Plugs holes!
So yeah I didn't have the plugs in tight enough.

Worse still I wasn't by myself, I had another forum member with me so I couldn't even hide my shame.

Funny thing is the weekend before I was pulling 190 rwhp on the dyno.
<shrug>

Anyways LBrown .. check around the spark plugs.

I now double check my plugs, and I have noticed occasionally they seem a bit loose and need to be snugged up.

LBrown8

I believe if its leaking from anywhere it will be leaking from my header, It is not leaking from my spark plugs because i changed them, it is not leaking from my exhaust because i just installed it, its not leaking from my mirrors because seafoam looks good on mirrors, and its not leaking from my *** because i wiped today. Thanks for the story. but this is frustrating as hell

I think you missed the point I was trying to make.

The point is: You need to trace where the leak is actually coming from for us to be able to help at all.


Just saying "seafoam leaked onto the ground" gives us nothing at all to work with. There are many other possibilities, including a cracked tube, the tube wasn't on tight, you used a funnel into the tube and when pouring slipped a bit out, the engine block is cracked, the plugs are out or not tight, the LIM gasket is bad, the LIM is cracked.....see what I mean? And that is assuming that it leaked near where you would be doing it, because it CAN leak from anywhere under the car because it gets swept into the exhaust system!


We can't help you if you aren't willing to give us information to work with.



never fear. I'd only be critical or bash you for it if I was hypocritical enough to ignore that I've done stupid stuff over my ownership period. Like cleaning the MAF and then not reconnecting it and panicking when I can't rev over 3k rpm and it's flooding out to the point that gas is streaming from the exhaust tips....

LBrown8

I will do more research when i get home!

Well keep us posted.

My mazda dealer has informed me, " you have a noisey aux port valve and a noisey air pump"
Noisey doesnt mean **** to me? I have a 3 inch exhaust and a aem cai do they not understand its not about noise?

LBrown8

Ok, so I have found the leak. It was a vacuum line below my LIM I do believe it was into my SSV as it was right behind my right wheel well, god knows how long that has been unplugged for. I changed my coils tonight as well and still no improvement. Now im worried that I have to declare another dead rotary engine. here is another clip have a look at this one. I hope someone has an idea

Compression problems manifest low and then climb higher in the rev range as it gets worse. This is because our compression improves the faster the engine spins.

Ignition problems manifest high and increase down the rev range as it gets worse, because higher RPM puts a higher and higher load on the coils, heat builds due to the firing rate, and weaknesses get exploited.

ESS problems can happen anywhere, depending on how it's fouled

MAF problems typically get exaggerated the higher you go in the rev range, because the MAF is further and further out of sync with what is actually happening. Typically.

Vacuum leak problems manifest down low, and fade the higher you go in the rev range, because the leak is a smaller and smaller portion of the total air flow, so the MAF data is closer and closer to what is actually being pulled

Cat problems manifest at high rpm AND high load, and expand to include lower and load levels of load. This is because it's basically capping the air flow through the exhaust more and more, acting as a bigger and bigger restrictor.

O2 sensor problems can show up anywhere, depending on how it fails.

SV failures show up as having problems entirely before 3,750rpm, entirely after 3,750rpm, OR only at 3,750rpm, as that is the SSV's trigger point. Could be stuck open, stuck closed, flutters, etc...

VIV failures show up as having problems entirely before 7,250rpm, entirely after 7,250rpm, OR only at 7,250rpm, as that is the SSV's trigger point. Could be stuck open, stuck closed, flutters, etc...

APV failures show up as having problems entirely before 6,250rpm, entirely after 6,250rpm, OR only at 6,250rpm, as that is the APV's trigger point. Could be stuck open, stuck closed, flutters, etc...

VFAD failures show up as having problems entirely before 5,500rpm, entirely after 5,500rpm, OR only at 5,500rpm, as that is the VFAD's trigger point. Could be stuck open, stuck closed, flutters, etc...

air pump is always fuxking noisy.

and ... u do know your carmera is off the center so I can't see the rpm ... right ?

LBrown8

The idea was to hear the sound. I appogize for not having my iPhone fixed to the rpm. Thanks so mynah riwwp I'm going to just bunker down and wait for my plugs now I guess .

Bonesy

Wait a mojo, Where is this nipple under the LIM in the wheel well? Is it the service nipple?

DarkBrew

The line to your LIM should be from the vent on the accordion tube and used for the port jet intended to improve air velocity.
