    Recently bought the car and have been driving it like a slug, after a week it has started to develop a new engine noise and being a potato when it comes to anything more than basics I think its more appropriate to ask a community that may know what they are talking about.

    Some other notes: It is pretty much due for a service (283,000km- so I'm assuming its would be a major service)- not sure if there is a service items list around the place, going to have a search around.

    Eitherway, behold the 'noise'.



    Edit: Additional information
    After re-watching the initial video I noticed that it isn't as obvious as when the engine is warm. So here is the noise after driving about for 10 minutes.

    Sounds like one of the radiator fans. When the noise stopped so did the fan.

    Thanks for the response. I have my doubts, but I have added another clip of when the engine has warmed up. The ticking/tapping is rather obvious in that one.

    The fan noise was overpowering and that's what I thought you were talking about, so I didn't really hear anything else.

    No problems, I did review the video and it wasn't the most helpful. I'll just post it in a response too- but this is the tap after warming things up.
    Any ideas?

    Could be and exhaust leak from the manifold. Get a piece of hose and put one end to you ear and poke the other end around in the engine to see if you can find where the noise is coming from. Like a stethoscope.

    I personally didn't even think of this one. I will give it a look over tomorrow during the day and update the thread as I go. Thanks a bunch for the suggestions!

    The ticking noise is normal with the Commodore motors after a few klms. We use some Nulon worn engine additive and 20/50 Nulon oil and the tick is nearly unnoticeable.

    Sounds like the classic lifter or valve train noise especially with those kms on it, maybe due for new lifters which is a bit of work on the LS engine due to the cylinder heads having to be removed

    I agree with vr304, sounds like lifters to me. It's more noticeable right at the beginning of the first video because it takes a second to build oil pressure with a cold start.

    Gen III & IV LS engines are a PITA to change lifters as mentioned above and the early versions of these engines were known for having crappy valve train components from new.

    Some fresh oil might quiet them for a while but it's a bandaid at best. Better start saving up for the heads to come off. BTW, might be worth considering a cam swap and a set of good quality rockers at the same time?

    As the last 2 members have said,you can change the oil however this will only be a temporary measure,the lifters etc are buggered and you need to essentially do a top end rebuild or just change the lifters however as the heads are off may as well do the cam etc at the same time, the fans shouldn’t be coming on at start up so you may need to change the sender that’s located in the radiator ,I could be wrong ,hard to tell without actually seeing it in person

    If the A/C is on the fans will run non-stop regardless of coolant temp, albeit at a reduced speed.

    Yeah, I fucked up with that first video. It was started with the AC on.

    Seems like it's time to start saving, ouch.

    Update, was unable to find any exhaust leaks, so thats a let down.

    Decided to give it a listen with the classic screw driver stethoscope and it's pretty obvious its coming from around cylinder 5/7.

    Will probably go with this after I change the lifters over. Just out of curiosity, any preference on synthetic, semi or mineral? Due to the age I'd probably go with semi- but a few people here seem to only use mineral oils.

    Decided to get a quote for 12 lifters and a gasket, ended up coming to around $489. So it was less than I was expecting, thankfully there is a long weekend coming up. :cool:

    that's not lifter noise

    it is either broken crown, ring(s) or piston slap i would get a compression test before spending money

    my vote's for piston slap, might be worth chucking that nulon stuff in and perhaps some thicker oil, 10-20 weight might be a start. I'd have a look at your battery too, it was struggling to turn it over in the video.

    If this is the conclusion, I will probably be finding a new LS1 or alternative to replace it with. After reading about the additive, I'm pretty sure its liquid lies, so I will just get some thicker oil and see how that goes at first.

    The battery is still reading a solid 12.6 volts. I would probably blame it more on the broken ignition switch.
