Customer Self-diagnosis on a 6.4L

The other day I got the pleasure of working on a 2008 SuperDuty with a 6.4L under the hood. All I am told when I am handed the ticket is that the customer wants the exhaust leak fixed. Wonderful. When it is started cold, you can hear the leak as well as see smoke coming from back by the firewall. A quick peek through the fender opening reveals a exhaust manifold leaking but the rear pipes are also suspected. In our shop, we pretty much pull the cab for a lot of different repairs. Its rather easy.

I get the cab off, see the exhaust manifold leak but rear pipes look good. I replace the exhaust manifold gasket, torque all the pipes down to spec, and reinstall the cab. I start it up and do not hear a leak, so I take off on a test drive. The truck falls flat on its face whenever half throttle or more - so I wonder, what did I do?...

Hot exhaust plus fresh oil can lead to a fire....

Tune-Up in a Bottle

Let's be honest here; if your car is running like crap nothing added in the fuel will fix it. Think of these products as preventative maintenance. There are several products on the market that advertise that you should just add it to your tank to magically clean the fuel injectors. Other products say to add it directly to the crankcase to get the gun out of the oil system. In my experience, most of these products are an expensive sham. You'll be surprised which one does the job!...
