Your standard hsv headers aren’t that bad if anything probably just the cats are the restrictive part, I’ve actually got a set on my ssv with some custom de cat pipes as they are an upgrade over stock ss log manifolds

You really want to give it a good clean with some degreaser 1st and then make sure it is actually coming from the oil filter housing and not somewhere else

Nice colour mate, any mods done? Auto or manual?

Man if only our fuel prices in NZ looked like that, well over $3 a litre at a lot of places:oops:

I’d run penrite hpr 10 in it

If you’re wanting a tune then get a good custom dyno tune for your vehicle and mods rather than muck around with a factory tune for another model

As the other guy said remove the drive belt and run the engine for a bit and you’ll know for sure if it’s a driven accessory i.e. idler pulley, water pump etc or internal engine noise

Nope, different throttle bodies and different locations

Hard to tell just by reading your description but that clunking could well be engine or transmission mounts need replacing

Add some nulon lifter free to your oil it’s really good stuff and will definitely quieten down your lifters as for the trunion upgrade there’s no real need to do that with your stock cam but if you’re planning to upgrade your cam then do it then

Penrite for auto trans fluid with a filter too naturally and Penrite hpr 5 for engine oil

You really need to get it tuned too with those mods for one to get the best out of them but also it will throw the fuelling etc out and you’ll get o2 sensor fault codes with the headers

Looks awesome mate :cool: nice buy, add an otr, headers and tune to wake it up nicely

Just be aware that if it’s been lowered it may well have the shortened shocks that go with lowering springs so if you put standard height springs on shortened shocks it won’t handle ideally

I thought vk heater hoses were the go to for rerouting in ve/vf commodores?

Haven‘t personally seen one in the flesh myself but apparently black ops are a pretty decent and fairly cheap system that sound good according to the boost gumps YouTube channel, having watched a lot of their content can definitely say they know what they’re doing and talking about

Apologies if you’ve already mentioned it but what engine and box are you planning to run in it?

I’ve never bothered torquing the caliper bolts and never had any issues just do them up tight and call it good, put a little bit of blue loctite on the threads if you’re paranoid

Top picture is an example of what your exhaust looks like although will be a single pipe and single centre muffler but the shape and route it follows is the same below is a ve sedan system, it says v8 but fits v6 as well so you can see why a ve exhaust system won’t fit your vu… not even close...

Not sure where you’re getting your information from but there’s no such thing as a 300kw v6 ve and also as per your other comment in the other thread a ve exhaust system simply won’t fit your car they are a completely different layout underneath, those mace 69mm throttle body’s work with the...

You do realise an exhaust system for a ve won’t fit your vu, totally different body and chassis design, also they never made a 300kw v6 either, 5L throttle body wont fit on an ecotec either they only fit with the older buick (vn-vr) v6’s

A maintenance charger to keep the battery good, car cover will help too also won’t hurt to do an oil change before you put it away

He hasn’t been logged in since 2016 so you won’t get a response

Ve v6 isn’t anything spectacular power wise they are a big heavy car, even my ve v8 with some mild mods at times feels a bit slow

Naturally the alloy heads are lighter than cast iron but just curious as to weather the difference in weight over the front end of the car is all that noticeable with cornering etc?

What’s the drivability like? Any noticeable loss of down low torque?

No harm in switching to something like penrite hpr 10 (10w50) mine has half the kms that yours does and switched to the hpr 10 last oil change and all is well with it only noticeable difference is slightly higher oil pressure

The stock 5L is limited by low compression ratio and the std banana inlet manifold so you can cam it but don’t expect big gains by doing so, your fairly limited to a small cam for the above reasons

How much does it leave in there? Just curious

I tend to agree with ephect, if it’s possible to borrow a known good throttle body then put that on and see if the issue goes away

You didn’t go buying cheap plugs, leads coil packs etc off ebay did you? Could well still be your issue if so

They are also known to have throttle body issues so you may need a replacement but try the basics 1st

Try cleaning the maf, they get dirty over time regardless of how careful you are oiling your air filter, you need maf specific cleaner for it can buy it at the likes of super cheap auto and repco etc

I’ve also had issues with aftermarket caps leaking straight away from brand new, go genuine they are cheap enough

As the others have said would need to know what it was before hand, it’s just a tuning tool at the end of the day if you’re happy with how it drives then don’t get too hung up on dyno figures

He was last logged in April 2016 so your chances of getting a reply are slim to none

Can’t go wrong with either penrite or nulon, just make sure you use the correct type which is green in your case

Yip good stuff that 100 octane I run in it the ve and noticed it actually seems to get slightly better fuel economy over 98 on open road cruising

Wouldn’t imagine that would happen as it’s just engine oil with more detergents in it not an engine flush, if you’ve already got plenty of that oil probably just keep going with that
