Hi,

I just bought an R34GTR Vspec. It only has 30,000 km on it.

Firstly, it leaks about 4 to 5 drips of oil each night. I see it on the ground in the morning. What could this be? Are all oil leaks serious? For a car with such low kms i wouldnt expect it to be leaking.

Secondly, sometimes (i guess it's about once every 30 hours of driving--so not that often) when i have my foot to the floor revs will increase as normal then all of a sudden it's like it's only firing on 4 cylinders and i lose power. For example the other day i rev it to like 7000 revs in first gear, then changed into second gear and put my foot down again and immediately it was like half the cylinders weren't producing power. Sometimes ill just be driving slow, and all of a sudden it happens. The engine sound changes. Instead of it being the crisp ZZZZZZ sound of the skyline, it changes to Bop-bop-bop-bop-bop sound. Then all of a sudden it will be fine again and i get full power back and the car takes off again and the car drives for about another 20-30 hours without it happening again. Oil, water, temp, etc is always fine.

Any ideas? Thanks

the majority of oil leaks arent life threatening apart from the fact u have to keep replacing the lost oil..... oil leak could be anything.... u need to dip a bit of white paper into the puddle and find out what colour it is.... also shuv your camera under the car and take a pic of where the oil is coming from..... try and establish if its from the engine.... and if it is, things like is it coming from the front or rear, or either side.....also dont think just coz its got 30000kms on it things wont go wrong... iv seen brand new cars leak oil, or cars with 10000 blow a motor....

as for the missfire.... mate this could be any number of things....start off checking all the usual things.... check your spark plugs, your coils, all your electrical connections for the injectors, sensors and earth and get bak to us.

#1 If the oil is dripping onto the front diffuser from the front ie crank seal, it may very well be the 'Oil Pump' (or if you're lucky, the seal itself). If it is the oil pump, replace it with one of higher quality ie N1 Race-Spec at the very least. = big job

#2 If the car is already warmed up, it may be 'Coil Packs' rather than plugs (at this number of kms).

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
