Rb25 Knock/rattle From Timing Cover

[Fryer]

hi guys just need some opinions, I have a knock /rattle coming from the timing cover of the engine starts around 900rpm and goes away at 1500rpm any info would be great?

pop the cover open, see if the belt is in good nick and the idler pulley isn't hopping about

Had me confused

Pull the cover back and check as mentioned before..... Don't drive or run it too long if its behind the timing cover or bad things will happen!

Car is in getting tuned at the moment so hopefully it lasts there going to check the belt for me as well could the gears on the oil pump cause this noise?

If your oil pump is cactus, I don't think your motor would be running or that you would have any oil pressure. Best approach, is what I said before, pretty easy to rip off

If its a decent tuner then it will all be sorted so just sit back and wait

Just trying to think what it could be if it was big or small en bearings it would make the noise all time ??

Big end knocks can sometimes sound as though there coming from the head (i sure know mine did) if it does sound like its coming from the head could be a busted hydraulic lifter. Not overly hard to check but will require cams to be removed, how to repack deflated hydraulic lifters can be found online.

Keep in mind each one has 5 parts and there's 24 of them, so that's 120 tiny parts so if u decided to repack them be carefully as there not cheap

could be harmonic balancer going.

engine knock generally doesnt go away in higher rpm.

Quality right there

How far off is your 100k service? Better add a dying water pump to the list
