And that guy though his was was running good? I guess now he knows he wasn't.

Are my days numbered, probably are mods the cause of these failure probably, but I don't think the the whole story. I think its more a design flaw that gets aggravated by something more then "OMGZ Too many mods blew mez up!" As long as people like whoosh, Laloosh, Me, andre with the SST and some others don't blow or have problems rest alittle bit easier cause we'd all be candidates for the thrown rod category

Has anyone running meth & a fuel pump blown yet, built or not?

Not yet but I'd be the biggest candidate since my meth doesn't get used on my low boost. I'm about to switch it so it comes on at 10psi and higher instead of 16-17

[boosted3]

yea im going meth also seems liek people wiht meth havent blown there motor at all.a good tune wiht the meth at lower boost levels should give us the upper hand on the popped motors.Darksun big turbo most likely goign on after the holidays

Good I was starting to feel lonely with Chris leaveing

[oskinosmee]

I think my motor might be gone. I have Meth and a tune

Fuel pump? What PSI/turbo?

[Superstretch18]

Alright, so I asked this question in PTP's thread, but they recommended that it be asked here.

So here's the question; how many of the blown engines have had smoking turbos? I'm not pointing to the turbos as the issue but...

If PTP's right and some engines are running hotter than others with higher egt's, is it possible that they're the one's cooking the oil bearings on the turbos? If that's the case, is a smoking turbo an early warning of a potential boom?

Im not blown yet i think Darksun is right about the injectors.
but yes i have looshs fuel pump, 20 psi stock turbo. Snow meth kit

if iu have his fp that means u couldn't have had a fp for long? why do u think its blown?

His old PG Fp. It knocks above a certain psi i thought it was the turbo but it seems to spool the same. I also threw engine code p0303 3rd cylinder misfire. I mean shit IDK whats wrong with it. But the engine starts and runs fine with no noises until the turbo spools at various psi for a quick second and then it stops.

Do you have access to 100 octane gas? try running that and see if it changes

[magoo]

a few owners in OZ have gone bang.

[Silo]

Over here in Europe I have read about two engines blowing (whole into block) while cruising at 60... one was a MS6 the other a CX7. Isn't it odd that engines blow while at low load and closed loop? They don't just melt something, they end up with a whole in the block! Now that I read the reports here, it sounds like a pattern to me...

100 octane wont change anything its your injector seals. your gonna need a dealer visit and your gonna have to point them in direction or odds of them figuring it out themselves and just about zero.

[Laloosh]

its its the pump, which im guessing its not, it has a lifetime warranty from pg

Could be an injector. How hard would it be to get a compression test done to the motor. I would love to see a motor torn down before it goes boom. This would really give us some details to the problems that we are seeing.

[ptperformance]

Is it still one of the front 2 cyl's that blows all the time?

So everyone will stop bitching and pussy whining about how crap this engine is, here is the 2009 wrx "i blew my engine thread"

EVERY car has its problems. Subies have been known to have questional bearings for years now. Doesn't stop ppl from buying them or modding them.

Wow...lol...after reading that thread i thought I was on a Mazda site.

[Lex]

You have to be able to distinguish between a bad DESIGN and a poorly put together motor. Even a well designed engine can go with poor manufacturing and parts. Simple as that.

These engines are mass produced and there are bound to be lemons. Further, you will sell lemons come out of the woodwork much faster when you output 300hp out of 2.3l versus the 150hp of an NA engine.

So take care of it knowing you are dealing with lots of heat and potential wear and you will be ok. If you get a lemon - then that's just the luck of the draw.

+1. Although we seem to be in a better situation since meth solves our problem. You can't really fix poorly designed oil passages that cause subie rod failure.

[Darksun280]

Add that guy Duy215 to the list from this thread
http://www.mazdaspeedforum.org/forum/foru...year-atco.html

He came in the shout box and said he threw arod and hes trying to get the car back to stock

Any details?

[Breakdown81]

i was talking to him earlier, he hammered down on second from 3k to the top of the gear, shifted and the motor popped as soon as he let the clutch out. i dont know what the temps outside or road conditions were.

[JimmyMac]

Just got back from CPe. I'll update the list tomorrow. Thanks for the info! Hopefully I'll update my "personal" incident info by this weekend. Gonna start pulling the motor apart this week. Starting with the oil pan, then working my way up to the head.

[s-retire]

Car: Early 2008, mileage at failure 3607
Cylinder: 3?
Damage: Hole in block about the size of a rod end, engine compartment fire
RPM: 3,000 to 3,500 (5th gear, 70 mph, down grade load)
Mods: Bone Stock
Exhaust Manifold: Stock as built
Situation: Highway speed (I5 in California) Cruise Control set, down grade.
Warranty: Denied – Inspecting dealer claims that servicing Mazda dealer left drain plug loose and cause was it fell out allowing oil to drain out.
Oil: Dealer supplied 5w/30 stock # 103050. Oil changed @2300 miles.

Other: There was no indication of low oil condition prior to engine failure. The low oil pressure indicator light did not illuminate until after the motor quit. There was no increase in operating temp.

The oil was last changed at an authorized Mazda Dealer, so if you think using the dealer will protect you, think again.

I have written a letter to Mazda North American Operations to appeal the denial of warranty coverage. We’ll see what happens.

With the large number of denied warranty claims, has there been any thought to injured class action?

Has anyone else filed a NHTSA complaint?

[Darksun280]

all i can say is WOW. Take it to the dealer that did the oil change they should be forced to cover it.

Also wouldn't a motor seize before it though a rod if no oil was in there?

[mouse0330]

so this is no fault to the engine/or bad engine, just stupid dealer.

[s-retire]

Here is the rub. The dealer that performed the oil change sold the Mazda franchise later in the week. They are no longer authorized to do Mazda warranty work.

I don’t know about the seize vs. broken rod, but I’d expect the low oil pressure light to come on before a catastrophic failure.

[s-retire]

Assuming that the plug was let loose and it fell out 1300 miles later, allowing the oil to drain out; shouldn’t there have been some warning before the failure?

I’m thinking there is something wrong with some component. What am I missing? What would you suggest be my next step? I’m getting no assistance from Mazda corporate at all.

[mouse0330]

you have the oil change at 2300 miles, and the failure is at 3600 miles, if the plug was loose early, you should notice a lot of oil on the ground. Now assume the plug came loose while you were driving when this happens, I don't have an answer to that, but there should be a warning for low oil.

This occurred during a long road trip home from Northern Oregon. Last fuel stop 230 miles before failure. Last rest stop before failure 110 miles. No sign of problem at either stop.

[ms3jake]

It seems overall that Ms3 motors blow due to defects if you are near stock or you turned up the boost in some way. So if you dont have any defects, do some basic bolt ons (intake, tbe, mm) keep up with maintanence and dont overly abuse, the Ms3 should last a good while?

[MZRDISI4]

The low oil light comes on after it's already too low.

[s-retire]

I understand what you are saying, but it makes no sense at all. Does Mazda recognize that this is true? Do you have instances where others have had low oil pressure failures without warning?

The owner’s manual clearly describes action that should be taken to prevent engine failure after the light comes on.

I understand that a low pressure warning light won’t indicate low pressure in a worn out motor, but this motor is brand new.

Honestly talk to a lawyer, the mechanic/service manager can still be held personally accountable. I'm not sure it's be easy to get reparations out of them, but it wouldn't be hard to prove negligence. I don't think it's difficult to get a professor from an automotive school who is certified has a master technician to prove in a hearing that if the bolt was torqued to factory specs it would not vibrate loose. Could be a hassle, but would be worth it over an 8 grand engine( i think that's what they are going for)

[booya620]

question did the dealership change names when it was sold? If not the they might have bought the name and all holding which would make make them still liable. You need to request a copy of the sales agreement.
