Cammed LS2 - What engine oil?

No, I don't think that is an option that will be taken... You are aware of the difference between a valve and a piston aren't you?

 

You would consider timing chain part of the valvetrain.

Whilst not directly being part of the mechanism that controls the valves, revising the oil galleries does play a role in altering the effect lubrication has on the valvetrain.

Of course I don't know off the top of my head if specifications were changed in regards to material composition and valvetrain clearances between the LS1 and LS2 design so I can't comment.

However I don't think I am entirely wrong in what I have said. Also I have personally noticed that a lot more LS1 engines I have come across have a noisier lifter than the LS2 engines I have come across. Be this due to wear, care and engine run time compared to the LS2 is a distinct possibility (and more likely than not why I commented on valve-train noise in the first place). Whilst it is unfair to make a judgement like that because it is not really comparing apples with apples due to the age difference between both engines and obvious wear that engines develop, I guess rather, I made that comment to Jesterarts more as a 'real world' comparison in that his 'newer' LS2 shouldn't sound like an 'older' LS1.

I hope that makes sense!

 

No... Not really.

 

VALVE TRAIN: Definition

Phonetic: (′valv ′trān)
Area: (Mechanical Engineering) The valves and valve-operating mechanism for the control of fluid flow to and from a piston-cylinder machine, for example, steam, diesel, or gasoline engine.

OR

Phonetic: (′valv ′trān)
Definition: The most common automotive engine type of all is the 4-stroke Otto cycle variety and this particular design uses a valvetrain. Depending upon the particular layout, the engine incorporates an arrangement of intake and exhaust valves, lifters, pushrods, rocker arms and camshafts(OHC Only). These components work together, both mechanically and hydraulically, to allow the engine to take in air and expel exhaust.

I can definitely see in the above photo things related to our LSx enigines as per:-

Not saying anyone is wrong.... but... :hmmm:

Persoanll speaking I use Extra Virgin Oil in my LS1 and have never had any issue with valve train noise. oke:

 

Kewl, well 2 of the things in that list mentioned relate to the valvetrain.

Maybe you should've read my post underneath that one to re-interate what I was saying instead of being a smartass trying to belittle me.

You haven't even contributed to the OP's query so well done, do you feel better now?

 

Just to be clear who's and what list are you referring to?

 

The list you quoted me on.

I'm not sure if you were trying to come across as being a smart ass with your original reply, but thats how it seemed to me, hence my reply to you. If this wasn't the case, then just ignore it.

 

Seriously SilverVH - You're not worth the effort... However, on one point:- I never called you anything or inferred anything derogatory in any way.

As the saying goes "Preaches who preaches listen to what YOU preach" smartass.

 

Fail......

 

Edge 10W60 seems to be quite hit and miss with LS1's and 2's, some like it and a lot dont. Pretty much cant go wrong with a good quality 10W40

 

Can't say I've heard of any negative comments towards Edge 10w60 apart from sooks complaining about the price.

 

I've read a few comments saying they have used 10W60 and it made their engines very noisy, whereas with 10W40 it was fine.

I think if you have an LS which is getting higher up in kms then 10W60 probably isn't the best choice

 

I think it is a little trial and error. GIve it a go and if its good, then keep using it. If its no good, try a different weight. I dont always reckon it comes down to km's though, it comes down to how well looked after it is. If it has been continually serviced with decent oils/plugs etc, it is going to be in a hell of a better condition than something that has been neglected.

Thats just my opinion

 

Expensive trial and error when you need 2x 5L bottles at $80 a pop

 

More expensive trial and error when you need an engine rebuild due to a spun bearing, due to judging the quality of an engine oil by valvetrain noise alone.

 

Yeah generally that is right. I'm just basing my comment on a few owners with VY's I have seen who have tried 10W60 and had more noise as a result. They have gone back to 10W40 because they didnt like the noise (who does?) and have not spun any bearings as yet.

I tried a thicker oil (15W50) and although its not 10W60 I had more noise, so went back to 10W40. But at the end of the day, every engine is different and every owner has their own preferences. And like you say, 10W60 is probably overkill for cars that dont see the track, but that wont stop people from using it, because its the 'best oil' for LS engines

 

What is everyone's opinion on running the castrol edge 25w50 in a cammed ls2 with L98 heads, high volume oil pump, double row timing chains etc with only 70,000ks

The old owner was a mechanic and has always run this oil in it since he cammed the car, the car is only used as a weekend toy not a daily driver and since iv brought it I will be using it for the same thing, just weekend etc.

Now is 25w50 to thick? Should I be running a fully synthetic oil or?

Any opinions would be great

Cheers scott

 

Regarding the high volume pump, apparently you're better off using a thinner oil. Pretty sure it's because the oil can circulate more quickly, and drain from the top end back to the bottom end more easily too

I know that's applicable to older holden v8's, not sure if it applies to all motors in general though
