Fuel Leak !!!

Pic 1: Leaky injectors

Some time after my stage II mods, fuel smell inside the ER34 has become a norm. I took to it as nothing more than perhaps running a wee bit rich, hence the strong odour. Didn't really give much thought to it as I have a blocked nose most of the time. The little amount of passenger that the ER34 ferries would often comment on the strong odour whenever they board the car. I couldn't really be bothered because, well ..... fuel smells great to me! It's a natural high for us petrol heads. :P

What is getting a tad worrisome is that the smell is getting stronger, so much so that people standing outside of the car would get high and start doing the chicken dance. Ok I exaggerated a little bit here but you get the picture.

So anyway, I decided to take a look at what's happening under the hood. Using my nose like a blood hound, I sniff my way around the engine bay and it lead me to the centre of the engine bay. Lo and behold, those damn injectors are leaking fuel. All 6 injectors are leaking via cracked o-rings!

Now this sucked big time, I was scratching my head on where to find replacement o-rings. Order from SARD? I bet it will be ridiculously priced! Luckily one of my contact knows where to get it and promptly ordered some for me locally. With the o-rings replaced, the injectors are back to normal and no more fuel leakage.

A quick check around the fuel lines also leads to another leak. The Tomei fuel pressure regulator is leaking where the fuel lines joins the fittings. A quick change of fuel lines and new banjo clips solved that pretty quickly. After the above drama, the ER34 is now back to normal and hey no more fuel smell! Woohoo!

Is that the end of the ordeal? Hardly unfortunately. Strangely enough, a week later when I started the ER34 in the noon for a lunch appointment with alvint, it reeks of even stronger fuel smell. This can't be right at all. Pop open the hood and tracing the fuel lines, I saw fuel literally dripping off from the fuel rail adapter plate. Oh man, I can't drive the ER34 with it leaking fuel like that, I might end up with a big bang and have a burnt wreck as a car after that!

Took out my tools and gave it a couple of quick turns to tighten the banjo clips. This will serve as a temporary measure while I drive out to my mechanic's place to get new fuel lines and also a new banjo clip. Problem has since been solved and the ER34 has been running fine for a couple of weeks now. Phew! Lucky that is solved finally!

TCS and SLIP Light ON

Pic 1: TCS and SLIP light

Recently, my TCS and SLIP light lighted up permanently whilst driving. Needless to say, it's bloody annoying to see the light on my dash and what is more worrisome is that my TCS isn't working. Not a good thing as it's been raining a fair bit recently.

The problem is pretty erratic. Sometimes it lights up other times it does not. And when it lights up, it'll be gone after I stop the car and restarted it.

I've seen and heard of this problem before and a simple fix is to remove out the TCS module and give it a good cleaning and it should all be fine and well. Did just that and it has been fine for the past 4 weeks. Fingers cross that I do not see the some problem cropping up again. :)

97,000km Service

Pic 1: Time for new fluids

Just did my oil change recently. The ER34 has now clocked 97,000km and in goes the usual Torco SR1 10W-40 engine oil and of course the obligatory Nissan engine oil filter (Part No. 15208-53J00). Feels good to have fresh fluids inside the RB25DET NEO again. :)
