So, which one of the Rotella's would be good for this VW TDI engine? ALH converted to manual injection pump (12mm), larger injectors and a Cold Stage 2 camshaft.

 

Sorry.. no ... certainly wasn't intending that. LOL.

 

Dude... chill. I posted the article just for the sake of discussion. I'm not running up to the jugs of Rotella at Walmart and dry humping them. I'm running Pennzoil in my XJ and Mobil1 Synthetic in my Chrysler.

I just thought the article was interesting... particularly in regards to degredation of viscosity in modern day oils.

Here's what I can't figure out... when did you hop on the hate wagon? Because towards the beginning of this post, you were "almost sold" on Rotella then all of a sudden... what?

You keep going around touting about how "there's no scientific evidence for this, no scientific evidence for that". Okay, where's your scientific evidence AGAINST Zinc? ZDP? ZDDP? Moly? Boron? Etc.?

Not to mention the fact, while some maybe be concentrating on ZDDP, that's not the ONLY reason to switch to an oil like Rotella, DELVAC, etc.

By the way... you STILL didn't provide an answer to the counter-point I proposed in the thread where the new guy was asking for oil suggestions. If you're just here to play devil's advocate, that's cool man, just let us know. But you're coming in here being the antithesis to a lot of positive data without anything to back it up. Just sayin'.

 

^^^ I wasn't involved, but nice rebuttal post dude. lol.

Sorry man.. when I read the walmart bit... people in there are usually so weird... it wouldn't surprise me me to come up on that isle and actually seeing someone doing that. lmao. I'm sure stranger things happen in that joint on a daily basis.

 

You ain't lyin!!!!

 

yep... sometimes I think I need to go scrub my eyes with bleach after walking in that place. lol.

But seriously.. you did bring up a good, valid point. There's no problem bringing both sides of an equation, but crying wolf doesn't count. Gotta bring something to back a different perspective with... otherwise it's a "hollow" argument.

 

As for that damage photo of the camshaft for a 429/460 Ford. My Dad worked all his life as a school bus mechanic, and the stories he told about the era when most of them came with 429s in them, they had terrible problems with getting enough oil to the camshaft. They were always replacing them because lobes would be completely worn off. The 370s, based on the same design didn't have the problem, just the 429s for some reason. That damage could have happened no matter what oil they used in the engine if it was one with that problem.

 

I broke a camshaft in a 4.0L before. Shot it through the side of the block at cyl 6.

 

Here's the skinny on the 429. Some brilliant engineer thought they could make automated assembly easier if they put spit cam bearings in those instead of one piece bearing like they should have. These split bearings would "walk" over a short time and become misaligned from the oil supply hole and starve themselves to death until they spun.

The 429 got a bad rep because of this one flaw. And it's too bad because when proper one piece cam bearings are installed they are probably one of the best engines Ford made because they are a big block but what they call a "square motor" if I remember right. Too bad, I have actually built some and they are bullet proof and hard to beat with the right cam bearings.

 

How the hell does that happen?

 

Never figured it out but I think just lack of lubrication somewhere. I just yanked the engine and dropped in a stroked 4.2L instead. That tank ran for 5yrs before I parted it out.

 

Edited and re-opened.

sorry shaky haha

 

Oh, I ain't dead yet. I'll resist the Rotellite Cult until my final breath.
