[QUOTE=bmwman91;4871618]So I had a long phone conversation with Jim Rowe at Metric Mechanic yesterday....
Outstanding data point, and I feel better even though I just dropped $80 and a good used set of "square tooth" gears. Mine are pointy, although the wear is dead even on the contact side and non-contact. I would love to confirm somehow that the gears came stock with pointy teeth, that would be very interesting. Now on the oil conversation, like politics I often feel this discussion is best left alone among enthusiasts as emotions can run high, but did there happen to be any discussion of Shell Rotella? I have been an avid user for the 8 years I have mine and swore it was the highest ZDDP content oil out there. Just curious if that came up as I think we all agree that is the one thing these engines need later in life.

Yeah, the oil discussion might as well be an argument about religion, or politics. I do not know what all else they tested (I think he said they have done over 100 oils over the years). If it has high ZDDP content, then chances are it is perfectly good for this engine. I think that regular changes of the oil+filter and keeping the fill level up are at least as important as WHAT the engine is filled with!Last edited by bmwman91; 02-15-2018, 11:41 PM.

Thats about the same price i pay for a 5qt jug of it at Walmart. If you were to buy 5 qts of it. Cause it comes out to around 18 bucks before tax

I live in northern VA. So normally 1 qt. is around $7. I bought the oil at a military base, so I did not pay taxes. I bought 15 qts for $52 out the door.

The e30 market is an interesting mix of the "held together with bailing wire and duct tape" and " I can afford dealership prices for door gaskets" (I´m not knocking either of the spectrum, classic car ownership shouldn´t be exclusive to those only with deep pockets)
I think BMW may end up catering at some point to those with disposable income, to the detriment of those that love their e30´s but can´t really justify spending $1,000 on newly a minted sprocket from BMW Classics .
The e30 community is full of such talented and gifted enthusiasts. These are people who can fill the NLA void that BMW is neglecting to fill.
Maybe the community should form a Cooperative for the sourcing and manufacturing NLA e30 parts.
Like mentioned above I believe metal 3D printing technology will help fill the void in the next 5-10 years as it becomes less expensive, more perfected, and profitable from a manufacturing standpoint. Also if over that time data can show that a 3D printed part is equal or greater in strength and durability we may see some more NLA parts come back.

That depends, are the sprockets sintered or forged? The ones I had certainly didn't look like cast pieces. I don't think 3D printed metal components will ever be anywhere near as strong as machined forgings. A cheap replacement for small batch casting? Sure. Sintered parts? Maybe. A reliable alternative to forgings for high stress components? Highly doubtful.Last edited by varg; 02-18-2018, 05:35 AM.
