i bought a r33 gts-t from the auctions. sounded sweet, drove fine. Got the 100,000 service and mechanic said its fine. then i started noticing shocking fuel consumption!!1 like 290 off the whole tank and alot of black smoke on the muffler. ive driven it for a month and decided to check the oil and its almost all gone :S

does this mean the engine is dead? or something else???

cheers

yeah like there doesnt seem to be a huge leak of oil any where :S could the mechanic have forgottent o put oil in(doubt it). im not worried about the black smoke cuz i think its petrol not oil but where did the oil go?

the car drives normally, th eoil pressure seems fine and so are the temps? there is no gray/white smoke :S

Change the oil again and check it every day to see how much oil it is using.

Black smoke means its running rich - not oily so you may not need to rebuild the engine. It may just need to be looked at by someone who knows what they are doing.

A *little* oil around there is not a big issue, but check the O2 sensor thread. Apparently Nissan recommends changing that sensor every 40,000K's and I doubt your mechanic did that. Then hit up the spark plugs if he didn't change those, if he did, find out what went in there and check that they are the right gap and heat rating.

After all that, reset ECU and let it relearn?

Wat happens is the seal on the turbo goes and it will suk oil through the turbo and out the exhaust

it happened to my TX3T and i needed a total engine rebuild + turbo rebuild and a mates 2.6t sigma engine just rebuilt with no turbo rebuild and his shot oil out of the exhaust

a turbo rebuild solved it

yeah im with R31Nismod heer, if u had low oil ud see the warning lighjt and ur oil pressure would be low :S make sure u check the oil after then engine has been off for a while so it can collect,

cheers

btw if there is no grey/white smoke then ur engine is probably fine, if ur losing oil it might be a gasket somewhere, you should get it checked out either way

      98 R34GTT 4k engine stumble

      By JC71 路 Posted

      forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k.

      98 R34GTT 4k engine stumble

      By JC71 路 Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin 路 Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
