i know thats what i mean some thing has to be broken or loose im thinkin lol

just dump the oil. See if there's anything in there and go from there. If you haven't changed the oil since it came in you should do it anyway. Should be changing all the fluids.

yea just have about to have a look now n see if theres any metel in it and if there isnt ?

Put new oil in it and try again. Some times heads will tap when they got old oil runnin through em. My old evo was a clasic for it.

Bugger.

take it from me, I've been swinging spanners for over 20 years and had my own big end go in an RB and the location of the noise absolutely stumped me even using a stethoscope, but it was a big end.

Get a proper mechanic to look at it ASAP. Stop running it and revving it or you could have a rod snap and punch it through the block/stuff the head or both.

I was a mechanic for a long time and stepped up to mechanical engineering and the best advice I can give is call one of those mobile guys to have a quick look, pay your money for their rime and then start getting quotes on the job and you will be glad for the money spent. I still build my own race engines so I'm not at all out of touch. Look in the thread below in my sig if you want to see some of the stuff that goes bad in RBs.

At the risk of being way off track, you haven't stated whether this happens only whilst drivng or when parked and revving as well. The reason I say this is because just after picking up my Stagea after purchase, it developed a knocking sound just like you are describing and I did the stethescope thing nd all sorts of buggering around. Even had a mate take it for a drive with all the console out so I could probe the gearbox and transfer case etc because it was only at very certain revs we could hear it. It actually turned out to be the uni joint on the front driveshaft and I only got it just before it snapped "shudders".

not thrust bearing happens when i press clutch lol guess its big end or cracked piston should find out tonight :ninja: looks liek im gonna haveto geta JUN 2.7 stroker for it ;):thumbsup:

Is it just when you push the clutch in?? Might just be a rattly multiplate clutch, i now many a twin plate are infamous for making the car sound like its gonna fall apart when engaged.

Best of luck mate, i hope not to have to a 'forced' rebuild myself... at least not in the next year or 2.

Might be a little late for my comment, but anyways.

I had a similar problem in my CA18det in my bluebird.

I thought it was a big end, cause it sounded familiar, as I have had a CA18 with stuffed big end before..

Sold the car for cheap as it was, to find out a week later that it was the lightened flywheel coming loose.

Yes I still have my legs luckily. :D

So yeah might be another thing to check...

But good luck anyways.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
