I just got my cam and heads done. I'm using amsoil signature 5w30. As far as I read it's good enough. I'm thinking about putting in some zddp additive.
I don't have cats so I don't really care that much about that.

It has more media and a thicker case. I have them in stock but they are over double the price of the PF48 at $12.95.

In the last few years we have seen a good amount of cam/lifter failures. All different brand cams so I rule the cam out. Most common answer was using whatever oil was on sale.
I think the cams falling apart is what causes the oil pump pressure valves to stick. I've had a mellings stick before.
So, best I could say is use the correct oil and filter, change regularly.
The zinc issue is more related to none roller flat tappet set ups and there haven't been any findings stating that lower zinc levels affect roller set ups. I've seen this exact same thing on 100% stock LS3 and L99's so I wouldn't attribute it to only aftermarket cams needing higher grade oils. I've also seen it on multiple camshaft brands so you can't say it is a Comp Cams issue. I've talked with a lot of long time GM LS builders and they generally say the check valves stick due to dirty oil and that can happen with any oil on the market or pump for that matter. It could be the detergents being used in the newer oils as well but this is all speculation at this point.

I also recommend changing your oil and filter regularly as I stated in my original post. Going forward we will advise customers to use Red Line 5w30 or other high grade oils with the PF48R filter on ALL vehicles including 100% stock cars. The cost is double but at the end of the day it is cheaper than replacing parts or an engine for that matter.

Kind regards,

Is the PF48R any better than a Mobil 1 or K&N filter?

Is the L99 pump any different than the Ls3s?

Has there been stock oil pump failures of L99s with cams? Dont think an LS3 conversion is Required for All cams (VVT?)

Seems to me the pump could still fail as a result of a cam failure on a L99.


Also (mentioned in one of my other threads):

Any reason besides cost why one shouldnt run a higher zinc oil such as the Joe gibbs LS30, even if the car isnt cammed (stock internals)?
.
This is a good question because I can only think of one L99 oil pump failure from this site in 4 years. There have been many LS3 oil pump failures reported and yes the L99 and Ls3 oil pumps are different.

Back on the road again...

Picked the car up on Friday. Now running stage two JDP grind and making 456 RWHP and 418 RWTQ. I am happy to have my baby back and will be changing oil more frequently!

Thanks for the lively discussion on this thread everyone. I hope no one has to go through this expense and at least takes away some learnings from my experience.

Thanks to Jordan and Jeremy at JDP Motorsports for the outstanding support and quick turn around of "UGO2SLO"!

-Dane

If I remember correctly, the oil pumps on the L99 can provide the higher pressure/flow required to modulate the cam phasing.

The Mobil1 and K&N Filters are both manufactured by Champion Labs. I prefer the A/C Delco PF48R to either of those filters personally.

I've seen the pumps fail in both LS3 and L99 applications although they seem more common with the LS3..

It certainly won't hurt to run a higher quality oil in any application.

I've just recently started running VR1 in my '69 after reading about all the oil issues.
Interesting, I'm currently running non-synthetic VR1 as well. Coming up on my first change since FI and Cam....hopefully it's coming back if it really did get pulled.

I heard the same. In fact that's what my shop was going to swap mine out for during the cam install (but we forgot ).

I tried searching, but is there any thread on C5, comparing the oils? Im an oil noob, and will be installing my cam in a few weeks.

I read in a few places that the Zinc content is a concern mainly with flat-tappet cams?

What weight do I need, and how often should I change it? (Its my DD)

My shop uses Mobil 1 on everything, so im still trying to decide....
