that and the bang bang puter, had to of upset the bearings

no i dont think knock was only ever 30 odd at bang bang, it was definitely already damaged before then

What type/brands of oil are getting ditched at 5000Kms?

i used to use Nulon fully synthetic a lot of people go for motul

its to do with synthetic oils passing by the rings and burning out your exhaust so when people say "oh it doenst burn oil' there mislead

i used to think the same 10000 is fine with synthetic but better safe than sorry

there is also a better reason but i cant explain it as good as i was told it :P but thats the gist of it

The reason I ask is, in the time I did 10,000 Kms I didn't need to top up the oil level at all. When I drained it, it was of course dirty coloured but certainly didn't look contaminated (ODO now reads 119K and I've never had it past 5.5-6K RPM).

A few people I spoke to suggested using Motul 8100 or 300V and changing at 10,000 simply because the oil is of a much higher specification than that used in 1995 when the engine fired up for the first time in the Nissan plant. I don't really know, this is my first turbo car!

keep in mind that 2 things stuff up oil....fuel & heat.....hence why regular changes in summer are handy not to mention tired motors need the oil dumped more often cause of fuel by-passing old rings

EDIT: and as Adrian said, peeps that boost more than others need to be more regular also (because of greater fuel by-pass under boost)

One that was daily driven to work, running stock boost should though..

My 20 only lived to about 105,000 before she died. Car was pretty much stock. Sometimes they just die young :P

I use fully synthetic and change it at 10,000, is there any particular reason why RB's need changing at 5000?

I thought it was for the turbo's. Turbos aren't supposed to like contaminated oil, wears out the bearings sooner.

And here's another I heard, that all these "race quality oils" we use dont have any detergents in them and cook mega easy because they are designed only to be used for say one trackday and then be thrown away...

We need oil Mythbusters :D

Chad, I guess mine fared a little better than yours then :P

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
