Mullet's Thunder Bus Build

[Johnny Mullet]

My bus always had a small oil leak.On the cross country trip I use 4 quarts for 5400 miles which was not bad at all. When I drove the bus Saturday I noticed a HUGE puddle of oil under the bus and it was 3 quarts low. I got it home and found oil leaking from the EBPV where the actuator rod goes through. I already have the EBP disabled, but now it's time to fix it.

I been wanting to do this mod anyway and the bus decided for me that it's time. I will be installing an EBPV delete kit on the bus.............

I suppose now would be the time to upgrade to a larger turbo from a 99 model, but ain't got the funds right now.

You have to use an additive or mix in kerosene if you want any chance of it running. Luckily, we're back on the + side of the thermometer so those worries are in the past.

I'm not sure whether you can readily get Stanadyne like you can DK. But the only missing from Stanadyne's Performance Formula All season, is the high concentration lube. It has a lube in it, but doesn't fall into the "high Concretate" category.
Winter blend diesel is very subjective, depending on your region and the bulk supplier. Also the rate in which places rotate their fuel, etc

here's a link from up in the frozen north, with 2 fairly common additives up here, as I've mentioned on another thread we use Stanadyne in the groomers. It's not cheap.....but nothing north of the border is.....

Right now I am waiting for my new EBPV delete kit to show up. Today is a holiday, so no mail.....

EBPV delete is cool indeed. one less thing to break or leak oil. I got lucky to have a texas bus that doesnt even have one..



what turbo does yours have? the 99.5 - 2002. has a 56mm wheel with a 1.00 AR compressor and turbine housing both.. 02.5 + went to yet another turbo..


bigger turbo might giver you less boost at low RPMs, although with an AT545 you are always running against the stall and get good turbo spool as a result.


im running non waste-gated and get 21 PSI boost at my max RPM.. im not sure what our head gaskets are good for.. the fords are good for 28 PSI, however they have a thicker head gasket to allow for the higher RPM so im guessing our cylnder pressure are a little higher.. 21 seems like a good number and my EGTs stay under control as long as i let it rev on long grades to 2500-2600 or so.. ill see just above to right at 1200.. which is doable esp for shorter times.. although some of the ford guys run 1250 all day i dont like to do it.. pulling the jellico mountain on I-75 at near 65 is damn enough power for me..

in your case if you start putting out much more power you'll wipe your tranny..

My bus has the original 1996 turbo installed and I decided not to upgrade the turbo. I will do the EBPV delete and that will be pretty much it for any performance mods. I wanted to do the EBPV delete after straight piping the exhaust anyway especially since it's disabled.

Since the engine is pushing 200K miles I am also considering rebuilding or replacing the injectors sometime in the next year or so. Of course the bus runs awesome and the old saying "If it ain't broke, don't fix it." comes to mind.

I bought a new set of stage 1 injectors a year ago and have yet to install them, I’ve got a couple that were “lazy” but once I turned my fuel up my idle smoothed out except when it’s minus 10 and the engine hasn’t warmed up.. I’m at 182k or so.. once spring comes I’ll probanly install the new injectors but I do sometimes hate to tear apart an engine that is for all intents and purpose running darn near perfect. I have the parts to do my exhaust like yours and will do that for sure. Mine comes out as 3 inches goes to the muffler, comes out as 4 then has a turn down that is lucky to be 3..
