8.2L detroit diesel HomeSchool 3-25-04  
Does anybody have any information on a 1988 detroit diesel. i was just wondering if there was anything i should know about these engines. I just bought a 1988 gmc school bus with an 8.2 and a 5 speed. I plane on driving it across the country, so if anyone knows of a common problem or something I should keep in mind for my trip, let me know. thanks

I'm looking at a Cobra class A motorhome with what i believe to have an 8.2L Detroit Diesel. so what is the bad rep these have? what type of fuel milage are we talking? how about power? this one has a turbo, it's gotta have power, right?

I have an 8.2. They have a bad reputation. But if it is put together right and you take care of it, you should not have any problems. Ours runs well and has not given us a lick of trouble. I do keep close track of the routine maintanence.

When we got it, it would not heat up above 142 degrees. Replacing the the thermostats took care of that. It still does want to run cold....170 or so.

We would normally crusie it at 2900 rpms. Since changing the drive axle we can now cruise at 2200 rpms. This makes a big difference in the noise level. The boost and temp seem to be about the same. The trans temp is up a bit and it actually works better at this temp.

You can get service and parts manuals for these engines on ebay or at your local Detroit Diesel store.

So, what sort of 5 speed do you have? I would like to put one in our bus.

We just purchased a bus (1984) with a 8.2l detroit diesel. I runs smooth but at speeds over 55 we are leaking fuel out of the weep tube. ( this is not good--it is leaking onto the exhaust) it idels smooth but the top safe speed is 50 and 40 going up hill. Do you have any suggestions on what to look for? I have tried to get a repair manual and can not locate one

thanks great

Hi All

I have a snapped rocker arm on the front exhaust valve. I have a full rocker assembly coming - how hard will it be for me to put on? What's involved? Thanks for any help you can give me.
