R33 GTST S1 (RB25DET)
The problem started last week, when i started the car up in the morning, it made a loud tapping sound (bit like a really loud tapped/lifter). Only lasted for about 5-10 second though, also ran rough during this time and blew white smoke?...(my wife was standing behind the car and saw white smoke). Any suggestions? i thought it might be lifters or even maybe the turbo???
I drove the car to work that day, drove around heaps on sat, and it had not made the noise again. Plus i could not see any smoke in the rear view mirror or anything. But it happened again this morning....so i just left it in the garage ....but same thing, it cleared up after about 5-10 secs or so. wierd.
One other thing, for a good while now i have noticed the bov(blitz) not working like it used to, instead the internal wastegate has been making more noise?? i thought this could just be because i have put on a bleed valve and am running 10psi. i did not think this was a related problem...but thought i would add it in anyway. the bov problem if it is has not been effecting performance, just means the wastegate is louder nowdays.
Any help on this problem would be appreciated, thanks
