Nulon? u add it ur fuel? oil? and can u get it at ur servo?

Add to the engine oil. Get it at Autobarn and the like.

Yep I get a noise too which sounds like the hydraulic lifters (louder than the ticking of the injectors) on my R34 GTT. Hope it's nothing to worry about, it's only done about 67,000 k's.

R34's dont have hydraulic lifters.

R34's dont have hydraulic lifters.

Cool, actually I thought I had heard somebody say that, same as the GTR.

So what could the noise be? Maybe it is just the injectors, but it is kinda loud sometimes.

dont they all tick?. rb25's anyway.

Yer I guess the RB25's all do "tick" a bit. Maybe I'm just being paranoid about it Will stop worrying now.

[Ryanrb25]

mine doesnt...my first one did a little bit...

even my mates s15 black top sr20 has BAD lifter noise on start up for a good 30 seconds. 30000km

[siddr20]

yea s15s are known for that problem..

Asked a few more people yesterday and the tappet noise is normal for RBs..

[RB20JT]

i will give this nulon stuff a go on the weekend and lets u's know. wait....do i keep it in there and it reduces the noise? or do i put it in there drain it then put normal oil back in? in other words is Nulon a cleaner or noise reducer?

[Jsikalias]

my r34 gtt does it aswell :S lol but its more noticeable with lighter oil so i just put thicker oil in it and it doesnt do it alot
