Check if its coming from top or bottom end of motor (not as easy as it sounds) If top usually lifters, if bottom end prolly spun bearing. If its a low pitched knock could be bent rods.

I can't listen to sound clip at work, but I've had a similar noise from my car for AGES. Came about 18 months ago and was intermittent, disappeared about 6 months ago for a month or 2, and now is back...

idk

Holy shit, that is SO much louder than mine. What did you record this on? I wanna record mine with my iphone and see if you can even hear it on the clip...

That sounds like something in the freaking fan or something :S

I have the exact same noise too... But it isn't constant. It comes and goes randomly but it doesn't get loader when driving. You can only hear it on idle whenever it decides to tick. Nothing has changed drivability at all either.

It's confused the f**k out of me for about 12 months now.

Spun bearing - mine sounded exactly the same just quieter. Mine went quiet at around 3500rpm.

I thought is was a noisy injector or a belt for ages - drove for 6 months with it happening - not a daily though just weekends.

Nothing changed drivability wise. It hadn't actually spun yet just started to pick up on the crank. Photo of the bearing in my build thread.

You are best not running your engine at all otherwise you will end up ruining salvagable parts of the engine.

If you want to confirm before you start pulling engines down get an oil analysis done.

my rb25 powered s13 just started doing that exact same noise...its loud every time i turn it on....and it ussually will go way after 5 secs or so..... drives normal and nothing seems to be wrong. only when i turn on the car it makes that sound...?

it used to do it much quiter before,but it stoped doing it for a while and now the sound came back much louder and uglyer....im just glad it goes away after a few seconds of being on.

not sure what it could be...Lifters/ near spun Bearing..? hope its not a spun bearing....

how much are lifter kits? ill try to record it and post the sound.

This is most likely metal on metal contact that goes away once oil pressure gets up to speed after starting. My spun bearing did this at startup for the first 3 odd months before the ticking began from about 2000-3500rpm which would have been load / oil flow related. Higher up in the rev range there must have been enough oil flow to separate the bearing and journal again.

Again I say spun, but what I had was actually just the beginning before it actually spun and seized the engine. Engine was ripped out and rebuilt before it had the chance to go all the way.

Just gunna put it out there, check all the belts on the pulleys, I had a similar noise and it was just the power steering belt that had shredded and was knocking on something in the bay everytime it went around.

      So it should work in my case?  I does not say R34 but it say push(i have push gearbox/clutch right now) No i wont...and i do not drift/race or do anything crazy with car so even a small box should be ok for a couple of months

      Another little story of weird shit happening

      Ha ha, yeah, I've had one following me around in my parts boxes since about 2007 I believe. Just a little iddy bit hole drilled in the one I have to let it vent out once pressure was removed from the engine side. Still no idea what I'd put it on, ha ha.

      Anybody affected by the M1 minefield this morning?

      By MBS206 · Posted

      Just read this... Just a little bit of a wild one! Do you think the driver was testing out a new feature/device for how to lose the cops in a high speed chase?   I also suspect, if the box has a road sweeper that does magnetic metal pick up, he does a LOT of work in the machining industry. Which is what most of that looked like, machining chips from a mill or lathe. And I bet they're RAZOR sharp! And from an environmental perspective they really do need to actually collect all of those little pieces too. I wonder how many people still cop flat tires over the coming months on that road?   As for insurance company, yeah, it'd be interesting to hear what they say to the owner. But realistically, he's right, that "It's his fault". In the way that, it was his truck that spilled it, so they need to clean it up. However, neither he, nor his insurance company may bear the end cost if they do an investigation and find out it was caused by someone elses negligence (And they know who)...

      Yeah, no matter what bad things people can say about Julian from Autospeed, he at least was capable of thinking and his inclusion of a check/relief valve in the plumbing for the Audi boost controller, that I made a copy of and used for years**, completely eradicated that problem. **It's still lying on my workbench where I put it about, um, 18 years ago and have never found a home for it!

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      I didn't actually know this! I've seen photos of the H1, mainly outside shots, and they just look "different". I guess there'd be a few little changes like nicer rims, and probably the fact they have nicer looking paint with some depth and shine, which will make any vehicles body look different to the very flat colours of the defence force.   I've watched the guys on GHPC convert their Humvee to LS1, and they've done some really nice front shock upgrade. I'm waiting for the next video on it with the rear end done. I can't remember if they've already done it, or I dreamed it, but I believe they're also supercharging theres. They will be in the future doing proper long travel suspension too.   If you ditch out your big V8, as rubbish as it must be, send it to my place. I'll let the unreliable V8 motor and box be here. I just like V8s... So I'll find something to do with it... Even if that something is just taking up valuable space in the yard. I might have something Skyline I can send back in payment... Or even Ford Barra motors  (From memory you're in Canada yeah?) So you can then play with the legendary Aussie 4L version of an RB...  Except they don't have that distinctive random miss at idle like the RB25 does.
