Title: 8V92 Silver questions
Post by: Hi yo silver on September 02, 2007, 09:07:57 PM
I'm looking at an '83 MCI with an 8V92 engine.  It's a Custom Coach conversion.  Will it necessarily have the "silver" engine?  Is it important to know?  What's the difference between the pre-silver and the silver engine?  I have no indication that it's a turbo engine.
Thanks,
Dennis

You really want a silver 92 and nothing else. DD had many issues with the pre silver motor and they were all expensive to fix. I would get the number off the motor and phone DD and they may be able to tell you if it's a DD number.

Be careful about just judging one by it's color! Rattle can over hauls are common among unscrupulous sellers! It comes in any color ya want at the Dollar store for a buck a can or about five bucks for a complete spray can rebuild! FWIW ;D  BK  ;D

The 8V92 Silver engines began with serial number F73594
The 6V92 Silver engines began with serial number F83425

Any serial number after those above would be a silver engine.  Production of the silver began in 1982.

If it is a 92 series it will have a turbo. I have never seen or heard of a 92 series without a turbo.  Jack

Jack, some 8v92 did not have turbos

For all practical purposes, all 8V-92's of the '83 era were TA's.  Most likely the engine has been rebuilt somewhere along the way, and as upgrades are made available, Detroit made them standard on the rebuild kits- so long as the rebuilder did not use an older kit.  Silver refers to the components that were installed in the engine.  If you have a healthy 8V-92TA, you have a Silver if your oil consumption is somewhere around 2,200 miles per gallon.  My first 8V-92TA was built in '79 and consumed a gallon of oil every 1,200 miles, or almost every fuel fill.  Good Luck, TomC

As always, thanks everybody for your help.  I assumed the silver series referred to the components and not necessarily the paint color.  I'll call the seller and ask for the engine #, and documentation of the bearing replacement that was supposedly done around 50k miles ago...total coach mileage now is 186k or so. Thanks again.
