For some context:
My truck is a Frankenstein of a few other fords and just so happens to be my first diesel. As it is most applicable to my questions, I'm specifically dealing with what I believe to be a 1994 7.3IDI factory turbo (I haven't checked the block code, but the turbo on it looks aftermarket/rebuilt and is non-waste gated so it could be a reg. block). When I got it, the engine was covered in old oil, leaves, and other particulate (this will come into play later.) I had decided to do return lines a few months ago and had done a poor job with injectors 5&7, causing a notable amount of fuel leaking into the valley pan. On a subsequent test drive, a friend pointed out that it was leaking quit a bit of oil on the ground. I regularly checked my oil level, and this leakage coincided with a loss of a quart of oil over 40 miles. At that point, I put it away for the winter until I had the time to work on it.
I started tearing into it this past weekend, first with the removal of the turbo. Most of my work on this truck has been a learning experience, and in getting the turbo off, the Lake Loch Ness of black fluid in my valley pan escaped down the turbo drain and most likely took some of the previously mentioned particulate with it. I am now under the impression that the leakage was just the old oil soaked diesel spilling off of the back of the block, but that would not explain my oil loss. I am pretty confident in assuming that a mixture of grimy oil, diesel, and random debris is not an ideal mixture to have drain into your engine.
With that being the case, here's my semi-educated guess, and related questions, as to what I should do.
Replace Turbo Seals.
- I've seen that typ4 has a ats/factory style seal kit for sale, but I am not sure if that is ideal for my turbo.
Drain Oil.
- Diesel is not a lubricant, and an IDI is not vegetarian so I have to 86 the plant material.
- What else can I do to deal with the introduction of foreign bodies into the oil system? It has not ran nor circulated the oil, so I figured that draining it out would be a good idea.
Remove/Reseal Intake Manifold.
- Is it easiest to remove just the hard lines to get the manifold off or does the pump need to be taken out as well?
- Is there any maintenance that I should do on it?
- Is their a gasket or gasket maker that I need to apply upon reassembly?
- What is the torque suggested for those bolts?
Remove/Reseal Valley Pan.
- Similar to above, what is the re-sealing procedure? I have heard about fel-pro gaskets but do not have the familiarity to know what is best.
- Is there anything I should check while it is off?
Remove/Reseal Valve Covers.
- Similar to above, what sealant/gasket does it require and what should I look for in terms of general engine health checks?
I've got more on the docket, but these are within my means in terms of the tools and disposable income I have available.
If you have suggestions, I'd appreciate the wisdom. If not, I can exercise my googling skills. A "TLDR" comment has never bothered me, so feel free to be cynical. Passive aggressive knowledge is still good knowledge.
Thanks,
