Fg Cams - Beware Of Wear

Is it because most cars runs full syn?

Seen the damage across 08,09 and 10 so its not limited to 08 models

But full syn was a common factor in all cases.......

I keep saying it for a reason ........

Yeah I was recomended to f**k the oil off that I was using and use some brad penn oil which is semi syn.

[JETURBO]

And an 2011 model

Just remembered that sorry

Brad penn and ulx100 are easily some of the best oils hands down and are semi syn

Nulon semi, maybe you shouldt take the rocker cover off. But if you do, take a photo , I would be interested to see the colour inside.

Well I have only been running the nulon semi for 500k's, just the ford spec 15-40. Only done 2 changes and the first time I did use penrite hpr10, which came out like water, was still quite warm.

So would you not recommended it? I thought it would be fine for a stock car. What do you use?

Ulx110 is full mineral oil

[arronm]

Well if that's the case UlX110 is going to be as efficient as JETURBO's K Mart gauges.

Maybe diff bush?

Boys don't panic until we get the tests back. Most of my lobes looked excellent with basically only rub marks on them. It's only a few that were concerning.

Again, if it was oil related, they'd all be farked as last I knew, the oil pump didn't differentiate distribution to camshaft lobes. Mineral is sh*t and semi syn is a cheaper alternative to running the proper stuff if you actually value your engine. All wear related testing you see that companies spend millions on in R&D confirms this fact.

Ulx110 is full mineral oil

Mineral with correct 3 additives, if you have an understanding of what oils job is and how grades effect ull understand why mineral/semi/full syn effect each aplication

Quote from ulx110

The oil has been on numerous engine dynos in Australia and the USA and to this date has never been beaten by any commercially available motor oil on the market in horsepower output, torque, drain intervals and fuel economy.

And if you have used ulx back to back on the dyno yourself it becomes very easy to see how good it is.

This debate aside ask any regarded engine builder their thoughts on a full syn oil on a "full roller" engine like we have and you will also get an answer that comes close to what a post above mentioned about "sliding" a rolling item

Love it or hate it engine design needs to be coupled with oil grades and blends and its no where near to suit a service cost

I completely understand case hardening and the fact there could of been a crappy batch or even pot luck bad ones but for 99% of us our engines very rarely exceed temps or conditions that the correct grade of oil can not handle, if we all "drifted" our turbos and they sat on limiter for bulk amounts of time yes the oil may not cope but knowing the fact our cars are more than likely just "driven" with the squirt here n there you will understand its working closer to stock load vs the tuned increased load that we modify for !

I believe any oil is good enough, as long as it's the right grade. (Viscosity) for your intended working environment...

I'm a diesel mechanic, and the latest truck engine technology (Volvo is my experience) is overhead cam and has four roller rockers per cylinder, has to have full synthetic oil with drain intervals up to 60,000k's

So in my eyes synthetic oil is ok, (and before somebody jumps in and says diesel oil is different, current euro5 diesel oil is perfectly fine for petrol engines, and all euro5 diesel trucks have large $15000 catalytic converters which are very sensitive to the incorrect oils, ie. anything before euro5

And I have also seen many cam lobe failures on Volvo engines, and it always came back to bad case hardening, some warranty even paying for cams with over 400,000ks

And back to the topic, I have a 08 turbo, and I'm freaking out about this, im nervous to remove my rocker cover
