03 5.4L (2 valve) head gasket replacement - parts list

[Eric M]

As descibed in this thread, my 03 blew a head gasket. As the motor has 185K, I figure I'll replace both gaskets at the same time. I plan on taking the long, slow route, by removing the radiator, etc. to more easily access the heads.

There are various parts that I'll replace while I have easy access to the motor and because I don't know if or when the previous owner replaced them. I'll paste the list below. If you can think of anything else I should include, please let me know. Thanks!

Parts (all gaskets excluded):

- cylinder heads ( resurface, valve job)

- cylinder head bolts

- spark plugs

- intake manifold

- exhaust manifolds (maybe)

- oil pump

- timing chain, gear, guides, tensioners

- water pump

- radiator hoses

Crankshaft bolt, and iron ratcheting tensioners. The Fel Pro head gasket set comes with about every gasket you'll need. The two O-rings on the coolant pipe nipple under the intake manifold should be replaced as well. Exhaust studs in the heads and on the manifold flange should be changed. The cross over gaskets on the intake manifold should be changed. Just inspect the intake manifold gasket surfaces for delamination while you have it apart. If no delamination is found it is fine to re-use the intake manifold (especially if it's a OEM Motorcraft part...). For achieving proper torque to yield settings I use a black impact socket and mark it with a silver permanent marker at 90 degree points that I can easily see while tightening. The head bolts are initially torqued to 30 ft lbs, then run through two 90 degree turns to torque to yield. Oil the bolts before inserting. The heads are interchangeable, the only difference is the tensioners oil passages are not blocked off with plugs. So make sure you have them setup correctly before reinstalling. Like leave the CHT sensor in the driver's side head to mark it as the LH cylinder head. Or just make sure you check the rear of the head should have the oil passages blocked off with the threaded plugs, the fronts should be open for the tensioners.

Like @Hamfisted suggested by linking the power steering pulley remover - get the tool and remove the pulley. Believe me, it will save time and frustration. Otherwise, the ps pump is a huge PIA to remove. Also, you will need fuel injector o-rings - 2 per cylinder. They are cheap. Need a front cover gasket and valve cover gaskets. Clean your throttle body while you have it removed. Consider replacing the heater hoses (a weak point on these), and other hoses while you have access. Would love to see photos and hear back from you about how it goes. Good luck.

Thank you! These are good tips. I will share some photos and let you know how things go. I foresee a fairly long process here, as I work pretty slowly. I will start disassembly in the next couple of days.

I would add the Harmonic Balancer. I did not replace mine on the last rebuild and it only lasted a year (250K miles total). The camshaft holding tools, for timing, are useful. I don't know what you have in your tool box for timing, but the timing tool is handy. If you want, you can get timing wheel from JEGS for $20 and innovative products long TDC tool to set timing. You can replace the oil pump with the front of the engine apart. Inspect your PS hoses. with the radiator and evaporator out, you have the best access you will ever have. Also, while you are there, if it hasn't been changed, the A/C clutch is pretty accessible. Finally, depending on the future you plan for this expedition, you are going to have a good look at the radiator support, it may be rusted out. It can be replaced with a little effort, I did mine, but don't be surprised if you see a lot of rust.

Many thanks for these suggestions. I think they will be worth the expense as I hope to keep the expedition for some years still.

A follow-up question, if that's alright:
Are these the two items you had in mind? Thanks.

- TDC tool

- Cam wheel

@Eric M
I think these are the tools you were wondering about. Camshaft holding tool to keep the cams in place. Another tool for positioning the crankshaft at the right spot. Both are needed to set the timing chains properly. They cost a few bucks and you might only use them once, but I would not recommend doing the job without them. I used these exact tools and didn't waste time fighting cheap-tool problems or failed attempts at short-cuts, and my 5.4 fired up right up after I put it back together.

Great! Thanks very much for recommending these. I will definitely get them. No sense in cutting corners on a job like this.
