Reworked k0-4 from PG. god hates me!!

[Captain KRM P5]

Do we know the reason behind it? I can't foresee the boost from the turbo being the issue. Most of the time it's from not running enough oil in the car.
We need to get this batch of turbos out, installed, so we can post other reviews because this isn't too appealing to the Mazda community, but sounds like the turbo held up like it should have.

i agree. i am beginning to wonder, after looking back at some of ms3guy22's tuning nightmare photos where all the smoke and blue smoke was occuring, whether or not that was actually the engine or the turbo pissing/consuming oil now.

I find this totally weird. How can he spin a rod? All he did was a turbo. Coincidence is a b****. Just a very random issue here. Please let us know EXACTLY what happens here.

sometimes you have to look at an automotive problem not in the sense of immediate cause and effect. you beat on a clutch for example and then baby it for a few months but it still goes out down the road, sooner than you would have liked. the damage could have already been done here by something else. the turbo can be eliminated from the cause because upon inspection the turbo was in perfect order - no shaft play, no shavings, spooled fine. if something let loose in the turbo and caused a rod bearing to spin (which is, for the record, a near mechanical impossibility), the evidence would be in the turbo. lets not forget he pretty much never boosted the engine on this turbo. he drove the car around and spooled enough to touch 5psi if that, and only once. there are people who get away with 30psi accidents on GT30s whose motors are still chugging along just fine.

i don't think in terms of coincidences. i think that all the punishment this engine took from the work and parts that came earlier turned the engine into a time bomb. bearings are in a sense, a wear item. if you beat the heck out of the engine enough they are going to wear out and do what happened here.

ur a fool!

really? is he? do tell why exactly you think that. we have speed6s and speed3s blowing motors and snapping rods on STOCK cars with ZERO modifications. we have DISI engines with crankwalk under 20,000 miles. we have mazdaspeed vehicles with more TSBs and service bulletins in two years than the regular 3 or 6 has had in five years combined and you think its foolish to consider there just might be some design issues with these cars?

all this going on while there are those who sit on the sidelines and praise the press release proclaimed strength of these engines and the genius behind the DI design. remarkable.

Someone please explain what "spun a rod bearing" means?

 

[ForceFed]

It usually means a bearing was Overloaded..or run dry and the coating on the bearing "Spins" off with the rotation of the Crank..Leaving an Irregular surface which is not good for a rotating assembly and usually causes failure and damages the crank in some cases.

I guess ur right. O god how i missed my srt-4. So namy parts for that car.

a bearing is a few millimeters thick of curved metal. like forcefed said, when it loses lubrication or when it wears down due to age or abuse, your rod is going to be rotating against the crank without the benefit of those few MM of cushion. thats why you hear that knocking noise, the rod is basically no longer tight on the surface and is rattling against the crankshaft.

LOL! I swear to god you jinxed me tonight Ken, my clutch finally gave out, I need a new one. Only mods I have right now are the turbo back and the cold air intake. Sorry for the off topic, but it's just a coincidence you mentioned that and the same night my clutch goes out. It's not terrible, but it is rattling against the flywheel when it's and not engaged.

"Now back to regular programming..."

Now I do have question. Is there a place we can go to look at possible bulletins for our cars. I know technically they are not supposed to be posted or distributed. It just amazes me. My first speed had nothing but problems. However my new Speed has no major issues except a clutch that seems to be really grabby. Hopefully the cars you have seen with blown stock motors are the ones in the early production run. God only knows.
While working on Benz's we had a ton of motors i mean a ton of motors going through oil consumption. The fix was a long block then a short block once they figured out the problem. Sadly which took almost 1. years to finally figure out. I just hope we Speed 3ers dont have any major issues.

 

[speed3se-r]

nevermind...

ur a fool!

 

[nytmar3]

Has anybody else installed one of these. My turbo is smoking and I would rather upgrade then, deal with the dealer. Just looking for some feedback.

God must hate you.

You could always put the old turbo back on and see if it still does it.

(stupid)

if you read the whole thread, you would see that the engine is blown from a spun rod bearing and that the new turbo was not the cause
