Marine injectors? Round two.

Hey Fellas,

I just rolled 150k on the ticker for the truck. When I fire it up in the morning theres a decent cloud of white which is only getting worse. I replaced the injector orings maybe 15k ago and cylinder 8 was wasted. I want to invest in some new sticks and have been told my some that marine injectors work great as they flow more while still utilizing the stock HPOP.

This is my daily driver, I already have the typical intake and 5 inch exhaust with PHP Hydra Chip which can be re-flashed for the new sticks. Im wondering if anyone has run marine injectors and how it was for towing and daily driving and what not. Dont want tons of smoke unless theres an ******* behind me.

Ive heard nothing but good things about Rev-X so I ordered some of that to free up the injectors in the morning. But if that doesnt work I want to have some good options that have been tested by others. Some WISE input would be appreciated. Thanks in advance.

As for the previous post about this my apologies. I was a few beers deep and slightly aggravated due to......well life. And for the "spool valve" that I referred to for the 6.0, I do not deal with many 7.3L as they dont fail. Much more familiar with the 6.4 and 6.7 for failures. Just looking for some input.

RevX or Arcoil may help if its an internal injector issue. What brand of O-rings did u install? It is possible that you may have nic'd an O-ring during install and it has just shown its face, so to speak. There is a thread around here that has a list of all A* coded international and CAT injectors that were ever made and the application they were used in and HP range on that particular engine.

Have you done an engine cylinder contribution test buzz test?

I'm sure it would be easier to Google it.

Marine injectors are something reffered to for cummins motors. I've never heard of marine injectors fod a 7.3, thats also because I've never heard of a 7.3 or t44e going in a boat. I would get a set of 160 or 160/100 and rock that, those will give you a good bump over stock. I'd recommend calling Tim at performance injection systems and talking with him on it too, thats who i use for all my injectors. As for dadditives, I know a lot of guys run the archoil because of the price and they say it works as good if not better than revx, but that isn't going to fix an issues other than stiction type situations in an injector.

Or at least ohm them out and check the glow plug relay.

X2 what he said, if it clears up after the engine reached operating temp. If it is all the time, then your probably gonna need an injector(s).

Get your truck buzz tested and a CCT done. That will pinpoint it more

How does it run once it is fired?

I would at least check to make sure the GP system is up and running properly prior to doing the injectors... just to be sure.

The orings were Motorcraft OEM replacement. I have access to an IDS so the buzz test all sounds perfect. The contribution flags 3 and 8 as a concern but the IDS will almost always flag companion cylinders. The smoke will clear up pretty quick maybe 2 or 3 seconds and it does seem kinda sluggish until at operating temperature. It is a 6 speed to I can feel a big difference. I wouldnt think the orings would be the concern again as it has been a few months since they were replaced and everything ran great until recently.

I am doing the oil change right when I close my computer and throwing in the RevX so I will update with the results and if this stuff is worth the price tag.

Also, I know Cummins queers have been running marine injectors for a while and I have personally seen a 7.3 in a boat (I about peed myself). I dont know if it was stock or not though. I tried to google the marine injectors with very little avail.

2-3 seconds of smoke is pretty normal, even for a non chipped truck. Normal also for not being ready to go until it gets to operating temp. Have you checked your EBPS and EBPV?
