Hey guys, I have a 2015 F150 with the 3.5 with turbo.
My son just had his wifes vehicle in the shop and both turbos were scratched. He was told by the mech that it is a real problem with these engines as there is a filter on them that needs to be changed out often.
My question is that should they? Mine has 160,000 on it now and as far as I know they have never been touched.
Is there a way to just clean these out? Or do I need to change them?
Your thoughts are encouraged!!
Thanks guys!!

I have a 2013 with same engine.. I have never heard of a "filter" on the turbo... I know many who say dont let the ENGINE OIL FILTER go excessive long as the oil is LUBE for the turbo ( as all engines are) ..... Changing engine oil at 5000 mile intervals with a good filter is highly recommended.. my truck has 97,000 miles
I know they had a few turbo problems ( life) back around 2010... But i thought the "upgraded" about 2012 and have had much fewer problems since then...

Only 'Filter' ever witnessed to a Turbocharger is the Base Air filter, if there is Scratching inside the Housings for the Inlet Side the shaft moving more pronounced as bearing failure or the filter has failed. Low grade aftermarket filters tend not to be as Minute a filtration value but will stop rocks or bugs to sand grains as easily. Someone feeding someone something Foul and Brown.

They take it to Fred's Brake & Alignment at 832 Rose St. I'll have to get my sons lazy butt in gear. He was going to bring me one of them so I could take a look at em. All I know at this point is that they failed and blew out the turbos. I guess this is quite a problem in the 3.5 turbo.?
I forgot the most IMPORTANT part,,,,,,,,,,,,,HE got this info from his wife who picked it up.....that should explain a lot.

The filter is inside block on supply line connection. it's just a screen. They are like $15.00 or you can clean yours.

what does it filter ?? What is the result of not changing the screen ??
apparently there is an inlet SCREEN on the oil line to the turbo.. It takes out BIG contamination that is in the oil... If you NEVER change the oil, or if you have an internal engine problem that puts out slivers / junk ... then the screen is suppose to catch that so you dont fail the turbos also......... "NORMALLY" the screens are never changed... unless you are replacing the turbos..

If are severe enough of deposits in those to stop them up, that engine is junk.

My brother, who gets paid to test drive and write articles about all sorts of vehicles, said to stay away from EVERY 'ecoboost' 3.5 turbo engine...... get the real V8 if you want to have reliable power.
I HAVE to respect him, he's older than me, so an elder !!

I've seen good ones, I've seen bad ones. Not an engine you really want to work "hard" as they don't have the meat in them to absorb the stresses for the power they can produce IMO. The cooling system used is adequate until it is used aggressively, or at maximum performance continuously. Great economy and serves well as a grocery getter but the farmers around here go to hauling grain carts, or bale carts with them and they don't hold up so well.

If your pulling CONSTANTLY, yea you want the diesel or BIG V8... not the 5.0
If your hauling a car trailer or a bed full of 2x4 and plywood, the 3.5 turbo is great... You have a 213 cubic inch engine that can get 20 MPG at 60 MPH on the highway all day long... Then when you PUNCH IT you got 400 HP to get that trailer onto the highway or pass slower traffic... I have used mine with a 10K trailer to pull a 9000# backhoe or a 7500# Bobcat.... But i do that once every couple months for an hour... Thats what it for. "NORMALLY" i use it like most people use a 1/2 ton truck... Hauling lumber, refrigerator, tractor parts, welder... and the occasional trailer.
The F150 is the best selling vehicle in the US and the 3.5 is the most popular engine. They started using them in 2011...... 13 years later and STILL using them....Quality and LIFE are NOT a concern.

I have a 2014 F 150 with the 3.5 and I use it like a rented mule. It regularly pulls 16' gooseneck stock trailer with 2-3 horses, a 7x16 dump trailer or a 20' equipment trailer with up to 10,000 lbs on it be it hay or equipment. I have 136,000 miles and I've had it since it had 20,000 miles. The oil has been changed regularly at 5,000 miles.
These are engines that do not do well if subjected to too long of an oil change interval or not being used and worked.

Well thanks for the info on the screen, but just where is it? Do I need to be concerned about it?  My F-150 is the 3.5 and it has 162,000 on it right now and I've changed the oil at least every 5,000. I take it to the Ford dealer cause I can't do it for what they charge. I'm VERY happy with it and I'm getting 19mpg city and 23 highway. I only occasionally haul a trailer and at most it's 3 tractors and that's only a short distance.
When I ever see my son, I'll try and get more info out of him. Thanks for the help guys!! Anything else I should look out for?

Change your spark plugs every 30,000 if you tow alot. It makes a world of difference.

there is a 3/8 inch steel line that feed oil to the turbo... There is a INLINE screen that screws into the turbo, and the LINE screws into that screen holder.. Arrow points to the oil supply hole.. Circle is the filter that screws into it..
reading online it seems like all the "EXPERTS" recommend 5000 mile oil changes to KEEP THE OIL CLEAN... If you go excessive, you build up crap and carbon... That has detrimental effects on the engine / chain tensioners / and any think that COULD plug the screens.... It appears that you dont do ROUTINE MAINT to the screen.. You change it out when you install new turbos / rebuild the eng/ etc.
