'93 engine code question

[bubbatexas]

On my '93 C3500 the valve cover decal says the engine code is RKJ and it states the est. horsepower as 200. Does anyone have any info on this engine, such as the differences between a "F" code engine and mine. It also seems to be a little louder than any other 6.5 I have ever heard, however it does have 360,000 miles on it. Thanks in advance for any info.

8th digit of your VIN?

Hiya Bubba... welcome to the site. This is THE place for 6.5TD stuff...

How about you take a minute to fill out your signature (click the link in mine and it will take you there) so we can all see that you're driving.

The 8th digit is a F, so I'm guessing that means it's a F motor? Also replacing the water pump is a PITA. Nothing like a SBC.

That means it has a F intake which is a good thing. The truck should have somewhere between 180 and 185 horsepower at least that is what my 93 says it has on the decals.

All oem 3500's are 'F' engines - at 360000 oem miles, yer in dire need of timing chainset, injector pump, and injectors, all sources of increased noise - properly done, the change in response and driveability will be startling - timing chainset should be done while doing waterpump, and doing IP is easier at that time, also

Replacement IP will be DB2-831-4911, just like on your oem label - timing will be: match crank and cam sprocket marks - rotate crank 360*, which rotates cam 180* as required to match IP and cam gear marks

Thanks for the info guys. The injection pump and injectors were replaced less than 100,000 miles ago. I will have to look into the timing chain before I put the new waterpump on (still waiting on some parts). I'll post a pic of the valve cover decal as soon as I can.

I've got a '93 as well, the 185HP mark is the S vin. My 93 FSM says the F vin is 210HP.

Kewl, i'll get one of my valve cover tag and the FSM specs & post those. There may have been different numbers for Fed, CA..etc. I know mine has the original engine, last 6 or 7 digits match the vin.
