nah im out all weekend and baby shower on sunday so yer ill be at my olds though i was playing around with my AFM my mate said that he heard that S1 AFM can unsolder on the plug dunno how true this is as i see no phsyical difference apart from a colored sticker from S1 and S2 afm Mine is green s2 is pink.

Now started my car and it died would crank over unplugged AFM started ran for at least 5 mins on a bumpy idlebut mostly above 500rpm i also gave it a rev np it wouldnt make boost and alsi seemed like it cut at about 2000-2500rpm this is from engine bay cable rev now i turn it off i gave my AFm a clean again let it dry plugged it back in started it as soon as i reved it it just died and also didnt seem like it was making boost (also led me to think a cooler pipe had split or blown off) but on a switch off then back on again i had boost this is all while AFM was plugged in then it died...unplugged my AFM started it idled without dieing for at least another 5 mins gave it a few hand revs and it still didnt die until i turned it off....So im thinking this problem is AFm isolated OR the plug or AFM loom.

Ok pulled the AFM apart i noticed that the plugs wasnt so tight in but more on one side then the other so after getting the plug off i filed all the prongs on the board and the plug to clean them up and got all the old solder off i then resoldered the prongs back on then tested with a multimeter to make sure power was running through it all four prongs were conducting nicely so i pluggged it back in started the car 1st start run np alil jumpy on idle but could be semi fouled plugs nothing major and did not stall at all seems all good so i put the top plastic lid back on siliconed it around the edges gave the inside of the AFM a generous blasting of Contact cleaner and its sitting in my garage ready to go back on tomorrow with the Pod filter lets hope my problem is solved.

Just to let you all know my problem is now fixed cleaned the AFM with CC and also resoldered the plug inside onto the board and resiliconed it on the top so far so good.

Just for others reading this thread, it should be noted that some contact cleaners contain a very small amount of lube, while proper Air Flow Meter cleaner does not, you really need to avoid using the lubricated cleansers.

      Stock rb25det neo questions

      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.
