Anyone ever considered a turbo pre-filter for oil feed?

This seems like a really good idea considering I've become the poster child for turbo issues. Clean oil and air is paramount, and this seems to be the way to go. particular for off highway vehicles.

Seems like a simple insurance policy, just make sure you inspect the element often. Is oil contamination what killed your last turbo?

Seems like it would just be more likely to plug and starve the bearings?

What oil filter do you run on the engine? Please dont say Fram

Not sure I understand why they do this. The main filter will filter out anything anywhere near large enough to get stuck or damage a bearing.

Some people run a bypass filter system. These are fine enough to pull soot out and are great for extending oil change intervals.

Adding a remote filter might work and use the same filter. Td5s have two filters. Centrifugal and regular.

Not anymore! I had no idea fram was shiite. Thats what my mechanic said today. "Stop using fram!"

What are the premium turbo friendly filters?

I agree with Adam... any filter would restrict flow and if it ever clogged, the turbo would fail quickly.

The engine already has an oil filter, so anything in-line with the turbo feed would be redundant.

You can read about it for hours on bobistheoilguy

General consensus seems to be Purolator PureOne is "one of the best". The part number that fits the Tdi is PL30001. About $7

Also what oil are you using in the engine? It's unusual that you have killed multiple turbos... there must be some consistent factor that is causing the failure.

Thanks. Where does LR genuine rank against the Top filters?
'
After break in, i switched to Mobile One Turbo Diesel for awhile then switched to Rotella T6. The first 2 turbo's died becuase of coolant contamination in the oil, due to a cracked head that i failed to recognize. so that was on me. but this last one needed the thrust and journal bearings replaced. that was a bit of a mystery. I'm going to take them to another turboshop to get a 2nd opinion since I didn't get anything conclusive from the current shop.

Chevron Delo 400LE. It's cheap at Costco.

I'd use Schaefer but it's so darn expensive. And hard to find.

This is sort of anathema to the post, but boost leaks will also kill a turbo. I'm sure that filtering helps but a lot of oem turbos on passenger cars run without them.

that was probably a contributing factor as well then. I had been battling a bad fitting seal and then a tear in my pressure side silicone hose. That is all resolved now.

Either of those oils should be OK, my personal choice is Valvoline Premium Blue. It seems to have the best anti wear additive mixture.

Good info about the boost leaks- that will definitely cause the turbo to work a lot harder!

How are your driving habits with the engine - do you give the turbo adequate time to cool down before engine shutoff if its been driven hard? (For example, if you live right off an interstate off ramp or at the top of a mountain, that turbo is going to be HOT when you pull into the driveway).

No issues with driving habits. It gets a cooldown after runs, especially on interestates. and engine always gets a minute or two idling before going anywhere.

I am going to run a pressure switch at the banjo fitting for mine just so I know for sure its getting oil. My turbo was eating itself last week and not sure if it had play before the rebuild (felt fine when I put it in) or if it wasn't getting enough oil. I cracked the line and oil was flowing to it. but for piece of mind I am fitting a switch so I know its getting oil.
