Here are the most frequent fixes we need to do on this Powerstroke series:

Oil dilution

Oil dilution is an unintended consequence of the emissions control process called active regeneration. Active regeneration technology injects extra fuel during the exhaust stroke. It raises the exhaust gas temperature and causes unburned fuel in the diesel particulate filter to combust.

There are two possibilities for why oil dilution happens. Some fuel injected during the exhaust stroke may bypass the piston rings and drain to the sump. 

You may have leaking injectors, which allow fuel to enter the combustion chamber when the engine is off, diluting your engine’s oil. 

You must check your oil level regularly, and when the engine oil level is over the max on the dipstick, bring the truck in for an oil change. Diluted oil will not lubricate your expensive engine as it should. We will test your injectors for leaking seals to determine why you have diluted engine oil.

Clogged Diesel Particulate Filters (DPF)

When the regeneration process fails to keep the DPF clean, the engine stays in regen mode to try to burn off the soot in the filter. The filter will become permanently clogged, and the engine will remain in regen mode, shortening its service life. As a result, power and fuel economy decline, and EGT increases. 

During the regen process, diesel fuel will be forced into the crankcase, diluting the oil and harming the engine. You can mitigate these effects using only ULSD fuel and CJ-4 low-ash specification oil. We can head off replacing the DPF by manually cleaning it during other services.

Leaking Radiators

Ford 6.4 Powerstrokes came stock with a deficient radiator design. If it hasn’t started leaking yet, it soon will. We offer a selection of aftermarket parts that will give you long service and provide better cooling for your engine.

Fuel-water Separator

Water in the fuel is a constant concern for diesel engine operators. Ford installed a fuel-water separator on its 6.4L Powerstroke engine, which has been troublesome. When the fuel-water separator isn’t drained often enough, it allows water to enter the fuel system, causing extensive damage to the fuel system. The Ford maintenance schedule is inadequate to alleviate this problem. We will drain the fuel-water separator with each oil change.

Failed Water pumps 

Stock 6.4 Powerstroke engines came with plastic impellers in the water pumps. We frequently find an overheating issue is due to inadequate coolant flow when the impeller blades fail. We offer an aftermarket water pump with a warranty.

Our technicians have years of experience working on diesel engines. We will return your Ford 6.4 Powerstroke diesel to you, running better than ever at an affordable price. Visit our website or call us at 510-793-6067 for an appointment.
