Hey guys ive notice a strong fuel smell in my car everytime i hit the throttle? ive did some checks like checking the engine for any smell or leaks but douldnt see any, so i go to look under the car for leaks on exaust etc... still no sign, so checking to see if they are coming from the air vents while window is up still no sign, but once i drive my car with windows down, the strong smell just appears?

any ideas?

cheers

Hows your fuel economy?

I sold my old R33 a while back and it had a similar problem, (could always smell fuel but could never find any leak) the guy who bought it off me said when he got it tuned the oxygen sensor on the exhaust was faulty and it was causing it to run too rich using too much fuel. If you have no fuel leaks and it's not been replaced in the last 40K thenit may pay you to replace it.

Check fuel filler, fuel tank breather lines, etc for perished hoses.

mechanics have tried looking for leaks through the fuel lines etc... but had no clue?

*note* ive got a dump pipe straight of my wastegate welded onto the manifold? could the smell come from the dumpy?

Fuel filler, from what i've read here. A mate of mine had the same thing (very strong smell when cornering) and it ended up being a crack in the rubber surround of the filler... which is added when complianced. (at least on his car it was)

i have the same prob with mine, i noticed a while ago wen i turn the car off i could hear a hissing sound from the fuel cap and the smell seems to be coming from there, going to put a new cap on it now to see if maybe thats the problem, u no, the cap not shutting properly, mite resolve my other acc issues, maybe im losing fuel pressure.just a thot, check it when u turn ur car off, listen to the fuel cap and smell that area.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure

      Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15

      J50 clock date suddenly reset to January 1

      Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.

      Wheel Sizes & Offsets For Skylines

      8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
