    Fuel Pump Install - Cam Position?

    Sure enough, I didn't! I didn't even mess with disabling the glow plugs and it cranked over on one battery with no problem. It took 3 tries (I think) to get the cam in the right position, and from there installing the new pump was easy. I started it up on the one battery and it ran well once it...

    Driving a T19 - Is it Bad to Start in 2nd?

    I originally thought 1st was unsynchronized because I can't get into 1st while going more than 1-2 miles an hour without double clutching, but the transmission has a PTO cover on either side. As I understand it, this means it must be a T19 (I found a few sources that back you up on the 1 vs. 2...

    Fuel Pump Install - Cam Position?

    Okay, well that's what I'll do. I've already put a good number of hours in this project, so even if it takes quite a few tries, I guess it shouldn't take long relatively speaking.

    Fuel Pump Install - Cam Position?

    Haha! Mine wasn't quite that bad, but it wasn't pretty either. I had to remove the running board too, and the bolts were so frozen in place and corroded they all snapped as I tried to remove them.

    Fuel Pump Install - Cam Position?

    Okay, so I should be able to just pull the fuel cutoff valve wire on the injection pump and give it a quick crank with the key, check the cam position, and repeat as necessary till it's in the correct position? Good to know! I won't be trying to install without lining up the cam lobe then...

    Fuel Pump Install - Cam Position?

    I'm in the middle of replacing the mechanical fuel pump on my 6.9 IDI, and I'd like to know if/why the cam position matters when installing the new pump. I'm thinking that if I put the new pump in exactly as the old pump was, it should be fine and cam position should be irrelevant as long as...

    Driving a T19 - Is it Bad to Start in 2nd?

    Yes. I can't speak from experience, but from what I've read, the gassers and diesels were equipped with T19s with different ratios--wide ratio for gas and close ratio for diesel.

    Driving a T19 - Is it Bad to Start in 2nd?

    I'm not sure. The truck has 400,000-ish miles, the engine was replaced at some point, and it's had at least 3 previous owners, so anything's possible. I'll have to look into that, because now I am questioning whether that is in fact an original diesel T19 trans.

    Driving a T19 - Is it Bad to Start in 2nd?

    I always thought that would be awkward with a bench seat, but I've got bucket seats with a center console and it clears just fine... as long as you don't actually have cups in the cupholders. I'm with you on not floating gears. NEVER have done it and NEVER will. If it was meant to be floated...

    Driving a T19 - Is it Bad to Start in 2nd?

    Thanks for clearing that up. That's about what I was thinking, but I was unsure. I'll probably just keep starting in 2nd unloaded and not on a steep hill because it does not feel like I'm causing any unnecessary or excessive stress at all by doing this.

    Driving a T19 - Is it Bad to Start in 2nd?

    I hadn't heard of wide ratio transmissions being used with the diesel engines in 83/84 before, but it certainly feels like a wide ratio to me. As to axle ratio, it is 4.10:1, and the tires are 245/75-16. I can't get much past 20 mph in 2nd.

    Driving a T19 - Is it Bad to Start in 2nd?

    I do not. I tried to change the gear oil once, but I couldn't get the drain plug to break loose, so I just keep it topped off. That is on my to-do list for the truck though. I'm sure with a bit more time and effort I could get that drain plug out.

    Driving a T19 - Is it Bad to Start in 2nd?

    So when shifting into 1st with the truck moving, I'm almost always coming straight from 2nd, but it's still like the shifter's hitting a brick wall. No grinding or crunching - it just won't go into 1st at all without double clutching. If I'm stopped, I can get into 1st from 2nd, neutral, etc...

    Driving a T19 - Is it Bad to Start in 2nd?

    I imagine that 1st gear ratio is much better suited to normal unloaded driving with 3.55s, but it just feels so low with 4.10s. With that said, I also love the T19 and the way it shifts. Now I'm wondering what exactly makes a true granny gear. The combination of the 2.41 2nd and 4.10 or even...

    Driving a T19 - Is it Bad to Start in 2nd?

    So I saw the current discussion on shifting ZF5s the other day, and got to thinking about how I drive my truck with a 4-speed. It's a 1984 diesel, so it should be the diesel Borg Warner T19, with a 4.02:1 1st gear and 2.41:1 2nd gear. I've had it for about a year and a half now, and I always...

    6.9 IDI Burning Oil Excessively

    That's good enough for me! I figure as long as I keep up with the glow plugs, starter, and batteries, etc. that engine will probably just about keep going forever.

    6.9 IDI Burning Oil Excessively

    At roughly 60mph/3000 rpm, it's really loud and considerably less efficient, but I try to keep it there just to avoid getting run over on the interstate. 3.55's and overdrive are definitely in my plans for the future! Oh well, it's fine for now, and maybe I can replace the stem seals once the...

    6.9 IDI Burning Oil Excessively

    I think it's funny that an extra quart between oil changes is considered not a lot, but then they aren't called oil burners for nothing! And of course, here I am adding sometimes almost two quarts in a week.

    6.9 IDI Burning Oil Excessively

    I will do that! Even if the oil consumption continues at 10 quarts, it'll be nice to know how much oil is actually in it when it inevitably drops below full.

    6.9 IDI Burning Oil Excessively

    I'm currently driving it to and from work, 45 miles both ways, 5 days a week. It's a mix of highway, city, and backroads driving, but mostly highway at 60 mph, so maybe 3,000-ish rpm (no tachometer). I wasn't overly concerned about the oil consumption, but I thought if there was an easy fix...

    6.9 IDI Burning Oil Excessively

    I'm using Delo 15w40. I went with Delo because I'd heard these trucks love to burn Rotella like you're talking about. Also, I don't know what was in the truck when I bought it, but I've only used Delo since buying it, so I have nothing to compare to in terms of how much oil it burns when using...

    6.9 IDI Burning Oil Excessively

    Minus the lack of oil in the intake, that's exactly how mine is too. I forgot to mention that earlier, but the exhaust smoke is really only there when my foot's in it or I'm driving on the interstate (so my foot's in it constantly).

    6.9 IDI Burning Oil Excessively

    I'm not sure all that oil is being sucked through the CDR. All I know for sure is that when I remove the air cleaner and the CDR valve, I see a significant amount of oil inside the intake manifold and CDR. Maybe there's another issue contributing to the oil burning? Valve seals? Piston rings...

    6.9 IDI Burning Oil Excessively

    My 6.9 IDI burns almost a quart of oil to a tank of fuel, and all (or most) of that oil seems to be getting sucked through the CDR valve. When I realized the inside of the intake manifold was coated in oil, I replaced the CDR valve, but the problem continued. I thought the oil might be...

    Injector Cap Leak/Damaged Injector 6.9 IDI

    Update: the leak is gone! I pulled out the injector, sanded down the scratches in the o-ring grooves, cleaned it up, reinstalled it, and drove about 15 miles without the slightest sign of a leak. I sure appreciate everyone's advice!
