I had the pass side one on my 2017 an it worked awesome and caught lots of oil, it will do the same on my 2018.

Well worth it in my opinion and haven’t seen a “major” need on the drivers side on other ecoboost motors in Mustangs or F150...so I’m good with it.

I need one for my T350 3.5EB, but the JLT one only specifies 150/250. I wonder why it wouldn't work for a 350. I didn't think there was any difference in the 3.5EB engines used in the 250s and the 350s.

It should mount the same. I’ll ask them to change it to include. They used my van as the original prototype and I had told them 150’s and 250’s probably. Thanks.

I have installed and used oil catch cans on several vehicles w great results. Mainly for boosted engines, but work well for the NA motors I’ve had too.

I know there are naysayers and some even can make up how it’s bad. #rollingeyes

On my Mustangs that I have tracked even Ford makes a catch can kit for them...so if bad, why would a manufacturer offer them?

Only reason not having one factory installed is need of extra maintenance. Depending on motor and use the can needs to be dumped anywhere from 2000 miles to 7500 miles.

Most of my cars and trucks I’ve been able to just dump at the oil change.

I’ve installed one on my ecoBoost Transit and in only 1000 miles (993 miles to be exact) I had one full ounce of oil in it.

My biggest thing is this is one ounce of oil I keep from building up on the back of my van. :)

Here is a link to the one I purchased.

JLT PERFORMANCE - Home of the JLT TRUE COLD AIR KIT

I have used this company for many years and they stand behind all their products and all made in the USA :)


...bring on the naysayers. LOL

Installed JLT catchcan on new ‘19 350hd 3.5EB. Learned after My daughters VW was throwing injector error codes. Took to dealership mechanic was very experienced. Took off topend and showed me valves. They were covered in 1/4” of oilgunk. Said it was blowback. Researched catchcans. For those interested took 3min to install. Outlined in red. Basically you unscrew can and empty blow-by oil caught. Asked obvious question why not installed by factory? Response given was typical customers barely change oil cant trust them to empty

I'm seeing a lot of catch cans with filtered breathers on the top and no hose going back to the engine. Is this legal? If so, will that setup work on our EB Transits?

Also, I like that the JLT cans are customized for the Transit so it's "plug and play" and I like that it's made in the USA, but do they work any better than the generic Chinese made cans that sell for 1/5 the price?

After doing a bit of research, I think my eco-boost engine would benefit from a passenger side catch can, but since I'm not positive it would I didn't want to spend a lot of money so I built my own using a pint canning jar, two brass 1/2" hose barb X 3/8" MIP fittings from Home Depot and a home-made aluminum tube large enough to hold a stainless steel scrub pad for the filter.

FWIW, I saw a JLT video comparing a JLT catch can to a copycat catch can that didn't have a filter. The JLT catch can with the filter completely filled up with oil before it started passing oil back to the engine. The copycat catch can without a filter on the PCV side started passing oil back to the engine almost immediately thereby catching almost no oil. The copycat can did have a diffuser screen about halfway down in the bottom part of the can, but since there was no filter between the input and output sides of the can, the oil was not separated and just went back in to the engine.

I installed my catch can using 1/2" ID fuel hose (from NAPA) and a holder I made for the jar to sit in using scrap aluminum I had on hand. Total cost: $16.12. I don't drive a lot (10,400 miles in 3 years) so it may be a while before I can tell if the catch can is working.

Are these catch Can units only for ecoboost 3.5 engineers? Would the 3.7 benefit from one do you guys know?

That Brillo like metal shaving filter looks like the inside of a industrial diesel engine Breather Filter, Which causes most of the oil to drip back into the Valve Cover and into the Crankcase.

The 3.7l engine does not build up the same kind of crankcase pressure as the ecoboost, so it is more important on the ecoboost. (And diesel as it is also turbocharged)

I wouldnt worry too much about the 3.7l engine. There are tons of them out there with many miles on them with no issues.

The 3.7 is a port injected engine and does not require any catch can. There is generally only an issue with DI engines needing a catch can.

Should there also be one on the driver side?
There could be, but in my experience with my cars and trucks with them, the passenger side really catches the bulk.

On my EcoBoost and on my naturally aspirated vehicles.
I also have Orton’s question. What is the reason for the passenger side needing one and the driver side not needing one? Does the PCV valve only empty into the passenger-side intake? Does anyone have scientific evidence that using a catch can actually reduces the carbon buildup on the intake valves?

Thanks!

So far only one person reported a problem and it is unclear if there was a problem from Carbon buildup.

That's what I'm hoping for - most of the oil to drip into the catch can and not go back into the engine.

Just a "Heads Up" for anyone who might build their own mason jar catch can. You should secure the ring that holds the lid to the jar so it doesn't come unscrewed. I screwed the ring down hand tight, but in less than 200 miles of driving, the ring came unscrewed, which turned on the "check engine light" and set 2 codes. So today I put a dab of regular household caulk on the ring and lid. I don't know if that will keep the ring from turning or not, but I didn't want to use anything permanent like JB-Weld because I will want to empty the jar at some time in the future. If the caulk doesn't hold, I may drill a small hole thru the ring and lid and put a small screw thru both.
