Sludge buildup sounds like a worry. I'll check mine next service.

Sorry to hear about your uncle passing.

do an oil flush at the same time.

and if your gonna check it, change the seal while your there..its what was leaking on mine.

Part number

OEM oil cooler O-ring - B1304-43U00

thanks bud

i always do an oil flush. every car, every service. never had a problem with oil sludge.

also sorry to hear about your uncle.

maybe ill replace all the hoses etc on the new engine before i put it in. would make routing pipes much easier with no car chassis around it lol

yeh but would that much sludge affect the tune if its all taken out?

you wouldnt think so!

maybe its affected oil pressure which is driven directly from the motor, thus engine can rev freely. i dunno, im sure scotty will come along and tell us why lol

i did it at scotts house. he says he didnt think so, until i explained how much was actually pulled out.. i actually scared him and i think he's checking his. he said the same thing about oil pressure and stuff. Its the only thing i did yesterday.. unless in between then my fuel pump is on its way out..

stock pump still? no youre running E85 right so you have a walbro?

hmm might be worth taking my spare off too and checking that........

ive got the walbro in. but i heard someones gone through a few of them(i think craig) but its not making any different sounds or whining..

ok, could that be the cause of your first turbo problem?? lack of oil

yeh i know its the problem..for both of them.. the banjo bolt hadnt been drilled out.. so if this gunk got in there. would of killed it instantly..

Im suprised at how good of a condition scotts stock turbo is.. i think its worth pulling that banjo out and opening it as soon as you get the car.

18 to 19 psi doesnt seem to do short term damage, that little turbo ran hard for 3 months without issue.

Im worried about the sludge but the other engine I had here was fine, I would say yours was just never serviced in Japan mate.

Lack of oil changing by previous owner would explain the sludge (Nissan oil is a mineral base).

Sorta makes you wonder how good these detergent additives in Sougi are if they are not cleaning away the sludge.

Glad to hear the car is feeling better (about time you got a break with that thing!).

EDIT: Bah, Scott got in before me.

nah your spare one did have abit around the adaptor bolt(if thats what you'd call it) but no where near as much as mine..

well thats just it, not only that i did a motul engine oil flush.. it makes me wonder how much was in there previously.. i think ill be doing another flush on the coming service, and pulling it apart again..

more importantly.. whats everyones opinions on the tune going out? i tried calling Cihan but his phones off..

im getting and AFR of 17-18 on full throttle so im babying it around now.. too scared to push it further..and definitely wont be.

but my Idle is A+ compared to before.

:mellow: isnt anything above 15 'lean'? Pretty sure my AFR's are at something like 11 (super rich)

It could definitely need more fuel now its spinning easier. I cant believe you ran nearly 300kw with a blocked oil pump and did no damage...

hahahahah i thought the same thing.. honestly im suprised i even got up there at all on a fairly rich de tune and that oil blockage problem...

:mellow: isnt anything above 15 'lean'? Pretty sure my AFR's are at something like 11 (super rich)

anything above 13 is lean. for us on e85, we dont really need to worry about cruise, but its only on full boost full ball.. before i did the oil fix, i was at about 12 -11 AFR at 22psi.. its the only thing thats changed..

i doubt the brake sensor cable has anything to do with it

Dunno anything about the tune, but at least you have taken quite a bit of stress of the oil pump (removed blockage so considerably less pressure builds up on the outlet side of the pump), thus increasing it's life span.

With those AFR's, at least your economy will be much better!

Just a thought, could the ECU have monitored either a lower than ideal oil flow or increased pressure on the oil pump and "pulled back" the tune, then after the clean out perhaps increased the tune to where it should have been in the first place?

(sorta like a mini limp mode)

Yup, but ethanol wont ping like petrol, it just runs hot so its not too bad for a quick squirt but you wouldnt want to run it that lean for very long.

I always forget you guys are on a different fuel >_<

i doubt it, i dont have any pressure or temp sensors in the oil..

will definitely go on the list after finding this but yeh.

unless we're talking about stock ECU. then i dont know. the only thing ive noticed change is mid to top AFR's.. low range is the same(but much better sinse the oil thing) and cruise is about 2-3 AFR's higher than previous.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
