Weird startup, white smoke chugs.
If you want to try to do your own timing use these instructions. http://www.cumminsforum.com/forum/94-98-tech-articles/257870-timing-40-minutes-12-valve-2nd-gen-engine.html

Question about BHAF?
I just wanted to comment on one of the earlier posts in here about EGT changes from having a BHAF vs. stock air box. The stock air box does not have a higher CFM than certain BHAFs They ones from napa range from 445 - to around 785 CFM, (not perfect numbers) If you use the stock intake tubing the filter will sit close to the turbo and needs a heat sheild or custom enclosure to lower the temperature of the air going into the intake from the temperature under the hood. I have heard of lowers of up to 150* EGTs when drilling a 3 - 3 1/2" hole in the firewall and running silicone tubing or pipe into the firewall hole, and cutting the same hole in the bottom of your stock, custom or aftermarket air box (as long as it's sealed) this will provide ACTUAL ram air induction and will cool your EGTs. Cummins recommends 50-80* for temperatures of air entering intake. Some people running BHAFs without heat shields run the risk of taking in hotter air than recommended. The insulation in front of the firewall moves aside to drill your hole, and can be moved back to cover the hole from sight, if need be. The turbo will however be louder inside the cab, only downside in my opinion. I want to build my own heatbox and ram induction for a Napa 2790 BHAF or should I go with the Napa 6637? What do you guys think about filter choice and what would you make the shielding with?

Easy way to set valves
I just did all my valves on my truck. Finally got the feeler gauge and some time to do it. Only a few of the valves were too loose, the rest just needed a little adjustment. I think it took me like 30 or 40 minuets in the cold rainy weather we're having. Found TDC by waiting for 1I and 1E to be loose and adjusted 1 I & E, 2 I, 3 E, 4 I, and 5 E, Marked my Top Dead Center and used Alternator bolt to turn 1 revolution. I proceeded to adjust 2 E, 3 I, 4 E, 5 I, and 6 I & E. Started the truck cold, engine lope seems to be gone now, maybe i didn't have a pissed injector. Still going to pop those and clean soon. Will drive Later in the day and post if it made any improvement in the poor state it seemed to be driving. Timing is still retarded, so I wont have much to go on as far as improvements.

Here is a link to a four part video for checks related to low power and other symptoms of issues. I don't know if this has been posted on here of not but has lots of info. Enjoy

I noticed you have the I5, what machine is that in and how do you like it so far?

- Weird startup, white smoke chugs.
Just recently in FL it's started to get cold. 30s at night... Haha real cold right :lol:Anyway, my truck has always started right up after sitting at night fine no problems.It has a brand new (as of a few months ago) Carter fuel pump fuel filter was changed at the same time.Lately however, after sitting all night long it will start up a little rough, no extra cranking, but will have to warm up slightly before taking off. If I don't wait for warm up it will run rough for about 2 minutes while chuggin, sputtering or whatever it is. If I leave it parked out of gear and give it throttle it will also sputter and spill white smoke.I might have a few ideas as to what it is, but I'd like to get some input from everyone.Yesterday I let the fuel filter drain a little while running the truck but it didn't help it today when I started it.I think it could be water or air I'm gonna change the fuel and oil filters soon. Along with the hose that was SUPPOSED to be marine diesel grade hose that seems to have some exterior cracks in it already.Let me know if I should check anything else. P.S. I think I may have the beginnings of a bad injector.Money is tight right now but I will be finishing up a job soon and should have a little extra cash to fix stuff. Let me know what you all think.Thanks Zach- Transmission Issue

- 3rd gauge for pod? water temp or oil pressure?
If money permits, get oil and fuel. My .02 centsCould be well worth it if something were to happen.There are a few places to custom mount a 4th gauge that are fun to do and original.- Power issue--Posted for VTCUMMINS
400 rpm is too low and is bad for your cam actually, with the low end torque the engine puts out. If it's a 5speed it should idle somewhere around 800 at idle. Maybe a little less with the AC on. Make sure that someone has not messed with the high end idle and that you are adjusting the low. Overflow valve could be bad too though. If it were me, I would hook a good tach up to it and adjust the idle or have someone who knows how do it quick. Only takes about 2 minutes with two tools to adjust it, while the truck is OFF. Also, once there is no more lope in your idle, from being turned low, listen to the truck as it idles, it should be constant if you here a lope you may have a pissed off injector. Another thing to check for, make sure that none of your fuel lines are bulging under pressure, if they are replace them so they don't collapse and clog the filter or fuel pump. Check the fuel heater pre-screen delete, repair or replace the heater element (middle section) because those will also draw air into your fuel. Obviously try replacing the fuel filter and overflow after you have checked all fuel lines and heater first. No sense in wasting money when it just might be dirty. Before you perform the fuel line and heater check run some Diesel Kleen through a tank of fuel. (I recommend only running Diesel Kleen and never put seafoam in your cummins.) And, see if that helps at all. After running the additive change out the filter and screens. If that fails sounds like overflowHope this helps- Help. Can't find info on green vacuum line.
I wish I could be more sure of where the noise was coming from, I believe the front axle but who knows. Unfortunately I need to do some seal work on both my tranny and my t-case, they have developed small leaks. I will be doing some more testing soon to narrow it down further. Thank you for all the info on this. It has definitely helped me, hopefully someone else can use it too.- Help. Can't find info on green vacuum line.
When it was happening I did have a vacuum leak at the time, and that very well may have been the transfer case shifting in an out of 4wd because it was losing vacuum so fast but gaining it back upon acceleration. Causing it to shift in and out, making a very audible "clunk". I really haven't been able to test the 4wd thoroughly since the repairs. I've only needed to use it for a few seconds at a time since then. - Weird startup, white smoke chugs.
