I did the same on the old 5.3 sierra and coyote. I suspect this will need the same. It looks like the ring pack will be a bit more efficient, but with all the cubes it will probably produce a lot of oil through the PCV.No, I've been thinking about it though. I used to have one on a 5.3 Chevy. Before I put it on I had to clean the throttle body every 25k miles or so or the engine would go into limp mode, Can't hurt...( as long as you remember to keep it emptied.)
No question that the valves are getting cleaned but are still having to burn the oil let by without it. That can result in a small power loss depending on how much is getting by. With the Hemi lots of oil gets by even with pot injection causing buildup in intake as well. So engines with poor PVC system filtration as well as DI or boosted apps tend to benefit. The 7.3l has not been out long enough to know how much oil will wind up coating the intake before the injectors yet. My take is it can’t hurt but if the design of the 7.3L doesn’t let much oil through than probably not needed one and a waist of money. Don’t see many running a catch can on the 7.3L yet so don’t know what is actually getting caught before getting back in to the combustion chamber. I will say am completely sold on catch can on the Mopar V8 even though just port injection.Not needed on the 7.3 as was mentioned above it is port injected. This means the valves are constantly being cleaned with fuel and additives during normal operation. One of the most desirable features of the 7.3 for me is that they got good power without using direct injection.
I saw one the other day made by JLT for less than half the price of the UPR.I had a catch can on my S/C Tacoma and about 1/2 cup of crap would drain out of it at each oil change. I'd like to get one for the 7.3 but I'm not paying $350 for it.
Does anyone know the specifications are for the fittings that are used for the factory PCV hoses? If I can get fittings, hoses, and a catch can a la carte that will keep $275 in my pocket.
Bad engine design, or just engine design characteristics? The 5.0 just a dirty engine?I have one on my 2012 f150 5.0 has 147k miles but it's a Gen 1 5.0 but my catch can catches alot of oil that being put back into the intake ... That that can gunk up the intake and cause issues ... I had to clean my intake after 100k miles it has nothing but oil in it ... And with the catch can it catches 90% of the oil that gets pushed in there
I still don't see why the 7.3 would NEED one. Seems like just a novelty.
It was the first gen so I would say yes but I don't have the oil consumption that the gen 3 5.0 have so idk ... But you want port injection over direct injection ... With port injection it will clean the values where direct injection doesn't clean the valuesBad engine design, or just engine design characteristics? The 5.0 just a dirty engine?
