Fucker's sticking again after only two days! $@"&¥€#*+^%%+!!

Hahahaha.


Some call it pioneering. Other's call it a pain in the ass.

GL man, and next time you take the spill valve and stuff apart for cleaning, you should do a thorough how-to. It's gonna become more and more common as more and more people run the "e", and it would be handy to have a sticky for the process.

Man this process sounds familiar

I'm sure. At least it's easy to pull and clean.

I'm wondering if it might be binding issues. The E85 isn't lubricating the plunger as well as pump gas was or something. I say this because I literally could not find a single speck of debris or buildup on the spill valve internals when I pulled it apart last time.

You have been attacked by the goo. Make sure the inside of the pump isn't sticky.

[silvapain]

Pump should be clean. I just pulled it two days ago and it was nearly spotless.

Maybe try adding MMO in there and see if it keeps it from sticking?

I could do that. I have some in the car and I have to fill up today.

Here's an MSF Top Tip for you:

If your spill valve is sticking and you get pissed off at it, whacking it with a small Mag Light will get it unstuck.

When it's sticking, do you hear any noises? 2 locals here, who've been mixing like 3+ gallons e have had issues with their pumps, and both times solenoids seemed to be stuck.... but even more, there was a loud ticking noise coming from the hpfp. Sounded bad, like a stuck cdfp piston banging the cam or something.

I've never had that noise happen. It usually quiets the pump down, considerably, when the solenoid sticks. Sounds like they may have something else going on :/

[djuosnteisn]

It sounded like a seized pump piston. Just wondering if you guys have ever had anything like that happen lol.

[silvapain]

When it wasn't working and I smacked it, I could hear when it started working. It made an intermittent clicking noise; higher and quieter than the normal HPFP noise.

anybody reporting issues with running mixes of corn? like E25-35 mix.

I am very afraid to mention anything due to my past fueling issues but I am on about 10 tanks of mix without pump issues.

RV/sensor/wiring yes but no pump issues lol

BTW just last week my shit started cutting out again..pulled sensor connector, sprayed with MAF cleaner, mashed the female pins together, re-installed and all was well....real annoying....

holy fuck that is horrible....ok so is it just me or is anyone else worried about an injector getting stuck open?

[wolly6973]

I was running a few gallons for a long time back when I was chasing KR. Went back to regular gas for about 10k, now back on a 30% mix for the last 5k

[djuosnteisn]

Like Daniel said, it cleans up real well with gasoline.... so IMO, mixes should be safe.

I'm a bit worried to be honest. The only consolation I have is that the injectors should be more resistant than normal port injection injectors to sticking, due to the high pressures involved. The gunk was very soft, and could be easily wiped up with a finger.

seems someone on here has already hydrolocked a motor due to a stuck injector...can't remember where I saw it.

anyway....perhaps a good cleaning method could be to periodically fill up with 93 since it dissolves the gunk in the pump.

so when you pull the Spillvalve for inspection and see gunk, run a tank of 93 through and then go back to E.

seems like simple insurance.

I don't think anyone running a mix should have any trouble however I'll pull my valve after a few more tanks full to see if anything is going on.

back when I replaced my CPE pump with about 5K miles of E-mix there was absolutely no residue on the valve.

[silvapain]

Hmm... Not a bad idea. I'll hate being slow for that tank though.

I'm heading to St. Louis this weekend, and I'll pull the pump when I get back and see how dirty it is.

[Dano]

hahaha go 50% then.

[phate]

I can't handle going back to 93, so eff that, hahaha.

Calvin from Cobb is the one who nuked a rod due to an injector failing. It just so happened to be after he switched back to 93 from running E85...I think that post is on the second page of my thread.

That post scared me more than any other horror story I've heard about this platform, lol. Since running E85, I've switched back and forth a few times, so I don't worry about these things any more.

[silvapain]

Are there any differences between MS6, GenJuan MS3, and GenPu MS3 injectors? I'm going to look into getting a second set of injectors and swap them with my original injectors, then send off my injectors to have them cleaned and checked.

[djuosnteisn]

Probably the wrong thread to ask.... but any idea where my ITFP SST is? Does bozo have it now?

roger that...so what you are saying....and just like any other substance that can be abused...once your car is on E85 you can't go back without possibly suffering severe withdrawal such as calvin's did.

I like to believe I have it under control...I mean I started out with E28 and that was good but really I am only going as far as E35... no really... well maybe E47ish but that's it.....

[specvspeedfreak]

I see all the experts are looking in here.. What is the bird chirping noise from my hpfp? I am getting more (and longer duration) after my e mix. It happens only at cold start .. I just revved it lil when it was cold and the induced the noise as well. I know I heard very lil of this noise with pump gas but now the noise sticks around for a longer time sometimes.... is this normal?

By your description of the noise it might be what I heard today from my spill valve.

With the car idling and the HPFP chirping, disconnect the electrical connector from the spill valve. If the noise goes away, you should pull the valve and see if there is debris on it.

I never had it myself. I think it was with @glorifiedbozo last I heard.

Si senoir, I should be sending it back on Monday as long as that's not an issue.

Edit: and any post with E85 is not the wrong place to ask if I have it, I think I am subscrided to most of them

Hahaha, exactly what i hoped for.

Monday is fine. Any day next week is fine. I'll pm you my address just to make sure you have it.

Yes. There are some differences...

username speed6 killah showed me 2 injectors @ one time, and I believe the gen2 has 2 holes in the inector vs. one (in the gen one).

I believe there is a pic on here somewhere and will post it when I find it.

Interesting... @SPEED6 KILLAH, are the resistances the same? If so, going to GenPu injectors might be a minor upgrade for a better spray pattern.

I have this chirp also.

It has to be related to e85 use, given I never had it before running a mix.

Is there a safe lubricant to run in the fueling system, and if so, do you guys have opinions on how much to run?

I put in Marvel Mystery Oil in last night when I filled up. The bottle says 4oz per 10 gallons.

I had absolutely no spill valve issues last night after filling up or this morning. It's way too soon to tell how the oil has affected the valve yet; I'll keep updating as I go.

There's no difference in injectors.

I pulled my injectors off a 2007 ms6 (which is pretty much as old as they get), and snapped a pic to show they were the same:






It has that same dimple as the newer ones.

Hmm.

I distinctly remember the one injector having only one hole.

Lemme dig up the pic.

@djuosnteisn

Here is the post I was referring to.

http://www.mazdaspeedforums.org/foru...tml#post909876

I see you posted that pic in the other thread also.

I was going from memory, and that the part #'s were different between model years.

My apologies for any confusion.

[djuosnteisn]

There's 2 holes in that pic, look closely:




The dimple is on the right of the normal hole, at 3 o'clock.

Ok Dustin...

I apologize for the confusion.

Please see my post above.

[silvapain]

The injector in that thread still has two ports.

EDIT: slow typing on my iPhone owns me. See you guys already figured it out.
