Project 7.3

[Bduck]

Bob, injectors are in the future and could be very near. As much as I've been wanting a newer truck (used, won't buy new), I don't need a mortgage payment and loving the life I have without a vehicle payment. The newer ford diesels have had costly issues with repairs & some replacement motors. Cost of injectors for my truck can be $1200+ depending the performance grade type and or replaced by dealer amounting to $5000+. My labor since I know how to do it might involve a special tool if any for a far less expense. Their newer ford diesel is getting better now but the 7.3 (1992-03) is made by International has been a proven motor. I've owned mine for 23yrs now. My other 2 vehicles are gas operated with injectors. My goal is to get another 10yrs out of my truck.

Roger,

One last tip.  When it comes time to replace your injectors, do it with factory rebuilt/certified injectors.  After I had mine repaired, I was told this by a friend that shopped auctions, rehabbed the purchases, and sold them to dealerships.  OEM injectors for that Chevy were about $800 X 8.  The factory rebuilt injectors at that time were $120 X 8.  $6400 vs $960.  Your money; your choice.

That is a good tip, Bob, we both are on the same track. My research has taken me to factory origins or to a reputable business that deals in rebuilt injectors, I have been making certain purchases from one business. When it comes to the sensors surrounding the 7.3 motor its best to stay with OEM, same would be for any motor. Sold on eBay are a lot of repackaged to look like OEM sensors. I won't purchase any type of performance product from eBay.

I was watching a movie one evening, since it was the holidays, I just happen to have my laptop. For a longtime always wanted to install a new front bumper on my truck but everything was on the expensive side of $2G+. I don't do a whole lot of looking at eBay but this time I did, found a bumper that caught my eye. Showed it to my wife & to my surprise she said go for it. It was well within the budget of temptation at about $850. Triggered pulled and within 4days delivery made. Opened box and found it was well packed, a 3-section bumper with each piece wrapped individually with a heavy bubble wrap & packed in a separate thick mill plastic bag. Next, I spent a good day bolting together the 3-piece bumper. At the seams where the 2 wings attached to the main section, I put a bead of sealant to keep out moisture & dirt from migrating in. Over the outside of the seam a bracket was supplied to bolt over the seam to hide seam. After installing bracket, took more sealant around both side edges of bracket.

The old bumper was an easy removal with 6 bolts accessible from front. Had it removed in 2 minutes. The original OEM tow hooks had to be removed, easy peasy. New install brackets came with bumper.

That's a nice bumper Roger, did you have to run new wires for the lights?

[Bduck]

Yes, ran my own wires. The wing lights are tapped into the high beams, the lightbar is on a separate switch from the 2 front mounted lights.

Next Task, there is a fuel pressure regulator spring located in the top of the engine mounted in fuel/water separator housing, very easy access with 2 screws in its own external cover attached. This stock spring is a noted culprit for engine to quit running which weakens under heat cycles of the engine not supplying adequate fuel press to fuel injectors. So, prior to replacing spring I installed a fuel press gauge in the cab. Fuel press at idle was 62psi, when accelerating to 75mph on interstate fuel press as it should drops off between 50-55psi and once speed is stabilized press recovers to 62psi. Truck runs really well which I would think its ok. Now, I replaced the spring and surprisingly fuel press at idle came up to 92psi which is 30psi more than old spring. I then drove truck on a lessor speed trip at 55mph, acceleration press dropped off to 76psi and recovers to stabilized 92psi. I don't know if the limits of the fuel press has changed but previous limit was 75-85psi. Research indicated the original stock spring was not heat treated and was the issue of weakening. The new spring is treated. New spring is $25.

That's amazing that one little spring could make that much difference in your fuel pressure.

Oil Leak at oil dipstick mount on passenger side of oil pan. 
This is one I avoided doing after finding out what needed to be done. This dipstick mount is inserted from the inside of the oil pan with an Oring that fits in a groove and a large thread protruding thru pan with a large nut attaching on the outside. The oil leak has been going on for a long time, dealer said back in the early years it would require engine removal to gain access inside oil pan. A $5G job I'm not willing to part with. I was able to stop the oil leak for a while just by snugging large nut, did this 2twice over the years until nut finally bottomed. Now I am that crossroad of having to address a fix. In the past 3yrs I found a couple of new fixes from diesel shops that sell those fixes. A tool was designed to insert into mount after dipstick removed so mount would not fall into bottom of oil pan. This aides into removal of Oring from outside. There are a couple of YouTube videos on the different methods of fix. One method was a total replacement redesign mount for the outside of oil pan. I didn't like this one which required old Oring removal and letting the OEM mount drop into bottom of oil pan, it has been claimed that it poses no threat to any moving internal engine parts. The threat would be the old Oring floating around if it fell in the pan bottom. What I opted to do is replace Oring on mount and Oring on dipstick about a total of $6.50 to OEM.
