Hi All
I've been a member for a few months now and this is my first post. I purchased a 1987 F250HD 2WD with 7.3n/a and C6 with unknown mileage about 2 years ago. When I purchased it I replaced the gearbox and fitted a GV overdrive which made a huge difference. Recently It developed a bad knock and the oil pressure dropped to about 35psi maximum, all this happened whilst towing. I thought I had done a main bearing or worse. Oh well looks like it's time for a rebuild. Only problem is there's not many 7.3 IDI's over here. Ford trucks were only ever made with petrol engines in Australia until about 1986 then nothing till late 2001 after Ford started to make RHD's in Brazil and imported them into Australia. With the help of the internet and forums namely "Oilburners" I've been able to find a wealth of information on them. I've lost count of the hours I've spent researching posts and Tech articles. So the journey begins. I've removed the engine which I had to do by removing the radiator support panel and grill etc. I didn't have the head room to lift it out the top. Once out time to dismantle, I found I had 4 stuck injectors, 2 head bolts that were rusted in and had to be punched out of the head, 1 head gasket that was about to let go, 8 slightly melted pistons and some main bearings that were starting to "pick up". Every thing else was as you would expect. The engine is now at the machine shop for machining.
I've been collecting parts to put in and with the rebuilt engine.
With the engine I'm fitting a new Banks Sidewinder, Typ4 cam, Moose junior pump, ARP studs, new lifters and valve springs, as well as the usual replacement items. I'm also installing a facet lift pump and replacing cab mounts. Attached are some pictures, Ill add more as things progress.
Thanks to all the members that have helped so far, your advice has been invaluable.
