Looking at Excursion 7.3L/have questions

[rowekmr]

Hello

I came across a 00 Excursion with 200K miles from a dedicated diesel truck owner. He had it 9 months but wants to downsize. He said the 4x4 didn't work and he replaced it with Manual Warn locking hubs. I understand that I have to get out to switch them and that won't always be convenient in the snow patches here or on the boat ramps. I was wondering could I have the Ford parts put back on to have it back to operating it from the cab?


Also on start up he says it produces white smoke for a few minutes and thinks it is either a O ring on a injector, glow plug or glow plug relay. What does white smoke at start up mean? He says it will do this when it isn't plugged up on a cold day otherwise there is no smoke.

Any mods that are recommended for a modest performance increase with better efficiency (mpgs)? I was thinking a better exhaust, air intake or filter and some tuner. It will be occassionally driven empty and a part time tow vehicle for a 8K and 9K trailer.

The hubs are all manual. There was never an 'auto locking' hub switch for inside the cab.
The inside switch is just to enable to vacuum pump to engage/lock the up hub when turned on and the selector for the transfer case for 4hi/lo.

When it's cold out - a little bit of white smoke is normal on initial start up for the first few min's or so until it's warmed up.

As for towing - best out of the box mods are either the 6637 filter upgrade 'or' the ZooDad mod if still using the stock airbox.
Then - upgraded exhaust. Diamond eye, or MBRP 4in from the turbo back will be all you need.

I wouldn't even consider a tuner or chip until you have some aftermarket gauges in, and have driving the vehicle for a while to make sure it's ready, and solid enough to take on some tunes or a chip.
