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.

      We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
