Turbo Oil Supply Screen Cleaning

Recommended Posts

I have worked on big V16 2500hp Quad turbo diesels for years and they never prefilter the turbo supply oils, the engine oil is just filtered thru four big oil filters. Sounds like they have engineered a problem into the bloody oil system,, clowns,,,

I will be negotiating this pretrubo oil filter change out every 30,000kms as a part of my lease I am sorting out,,

Nothing at all to do with the massive clearnaces in the large plain bearing full floating turbo's?......... Nothing to do with the massive reserve of oil that large medium speed diesels have in there sumps. Nothing to do with schedulded oil sampling being able to trend eng wear and carry out particle counts that will pick up particles much smaller than the clearances in the turbo's prior to eng failure. Nothing to do with turbos being inspected at 4000hr intervals and being changed out prior to failure based on component hours.

Ford haven't engineered a problem into the system the bean counters have. thats why this part doesnt get changed every service and this is also why ford specify a 15000k service interval. It makes fleet maintenace cheaper. That is where this problem comes from.

nobody but ford uses filters pre turbo,nobody loses turbos due to clogged filters but ford owners.

wake up and get rid of your filters!

I drilled mine out

It probably wasnt a ford thing you know. Youll probably find that garret requested this

Anyway. Ive been looking through the BA manual and I cant find any informaition on the filter what so ever. There isnt even an image of it :tonguepoke:

does anyone know how much for the full assembly and can they be bought after market or only from ford. lost the original turbo after 55000km due to a new mechanic using low quality oil, so not taking any chances this time by simply cleaning the oil supply screen.

Leave the filter out alltogether man. Dont worry about it, they are like 80 bucks at fraud. You are taking a chance even by putting a new one in as they are so restrictive.

to everyone who thinks you need this troublesome filter think about this.

you trust your oil filter to protect your main bearings,big end bearings,camshafts,cylinder bores,timing chain etc but you think its not good enough to protect your turbo.

in that case you are putting your entire engine at massive risk of failure at any minute!!!!!!!

the same debris that is trying to kill your turbo will surely wreak havoc on the rest of the engine internals.

the fact is its just not needed and can be the cause of catastrophic turbo failure so why risk it.

yes.

eliminate the risk involved with oil starvation due to the filter restricting oil flow to the turbo.

as I have stated before there is literally thousands of turbos running with no oil filter pre turbo (apart from the regular oil filter) yet I have never heard of such systematic turbo failure due to oil starvation as I have in regards to ford xr6 turbo cars.

I drilled mine out as soon as I got my car.no probs

Over engineering on fords behalf?

Why didnt you just remove the circlip and pull the screen out?

Yes the Circlip is tricky to get out but can be done. I was lucky enough to remove mine which enabled me to remove the fine filter assembly completly. I then reinstalled the circlip, just for some extra support for the banjo bolt due to the groove in the banjo bolt for the circlip being quite deep.

I guess you could leave the circlip out all together, but cant see it doing any harm being reinstalled.

Just take it out hey. Completely un-necessary. Runs better without as the turbo can actually have a drink. You cant even see through that gause its so dense its a wonder there was not a recall like subaru had. If I knew about this thing when my car was brand new, it would have been out at once.

Kinda makes sense. I mean how many other Garrett turbo powered cars are running around that never had this type of filter?

As mentioned earlier, the oil filter does a good enough job in protecting the engine, why would it not be good enough to protect the turbo?

at a guess guys what would a professional workshop/tuner charge to pull this out for me or should I do it myself???????

Cars booked in for monday just wondering if I should add this to the list or on my diy list?

I found it quite time consuming as space is quite limited. Was easier to take the oil filter off and remove the entire air box assy.

I wouldnt say its easier, I thought it was quite a sh*t of a job. I needed to pull airbox/oil filter out to get to it from the top and bottom. I put the car up on car stands.

I honestly dont think cleaning the filter is a good idea, as ive mentioned before, I pulled mine out, cleaned it then checked it under a microscope and it was still blocked. I then put it in the ultrasonic cleaner, tried a few more chemicals then had another look under the scope and there were still metal fragments in there.

I think its either remove or replace. Dont clean.
