Brief update on our engine replacement saga

Scott will watch the heat and is good to go. Don't have to use it. My 1991 DDEC11 8V92TA , although low mileage (97,000) is 500 ponies and is there if needed. The previous owner of a 75 fleet company of Oilfield 18 wheeler's (I'm second owner) would not have it any other way. Pyrometers and Heat Gauges are your best friend.

I like the 550 hp mine has and could not go back to crawling up the hills but mine is a newer engine with tons of gauges including eng. heat , trans heat , Pyrometers , boost , oil pressure as well as the normal gauges and the cat computer screen

go for it Scott

You have to somebody that knows the DDEC system to go to 500 hp on a DDEC ll 8v92 that is not a simple task like changing hp in the ECM

The Gentleman I bought mine off of had Stewart Stevenson, Odessa/Midland Tx. do the deed on His back in the 90's.

Donald,

I've made some mistakes along the way, but I'm still not out anywhere near the $22,000 of a rebuild even with my engine being redone and all associated expenses. I'm doing ok with this deal.

500 hp silver ddec II 8v92's are ok in my opinion. I have a laptop running ddlink version 6 software and I'm monitoring everything in real time all the time. Not too worried.

Cliff is right. Lots of stuff to change for 500hp. Ken Arnold did my last tune. Leid Diesel
Is doing the current tune.

Still ...

We used to use Delvac 1140 till it was discontinued several years ago. Moved to 1240. Or Exxon XD3-40.

I've always used shell rotella because tractor supply sells it all over for $15 a gal.

Shell is ok but stay on top of the oil samples for oil changes using it most of the time the changes are in 6 to 7k range with rotella

Do what you like, but my 8v71 had a substantial drop in oil consumption when I switched to Delvac 1240 from the Delo.

Scott & Heather · March 18, 2020, 05:07:10 PM

Bah...ok fine. I'll bite. I can't find the delvac anywhere. SS has it but I'm nowhere near them.

luvrbus · March 18, 2020, 05:25:29 PM

Order Delvac 1240 from Summit Racing 15.99 a gal, the Delvac comes 4 gal to case not 3,Delvac 1240 is a mineral based oil is the difference popular in aircraft oils for heat and stress

I think that you get free shipping on a $100. order too.
