My 05 f350 6.0l just started blowing white smoke while cold. After running for 20-30 min. down the road it stops. I did a pressure check on cooling system today. There seems to be no loss in pressure? Does this indicate head gascket or ERG valve or EGR cooler. If only the EGR or EGR cooler is this something I can attempt or should this be done by the pro's.

Are you loosing coolant? Mine acted the same , but I lost coolant . It turned out that the oil cooler was plugged causing a difference of temperature, which in turn blew the EGR cooler. fortunately it was covered under warranty . only $100. was told it would have 'bout $2300 otherwise.

 

I have lost a small amount but i am monitoring closely. Will I do damage by driving with such a problem?
Thank you for the help.

I drove mine quite a while. If it sucks down alot of coolant it is possible to hydrolock the engine. i.e. piston trying to come up and not being able to compress the coolant. The white smoke is the coolant actually burning. How many miles are on it ? The factory warranty should cover 5 years 100,000 mi..

 

72000 miles ,or so 183000 km Canada "eh". will call the dealer on Monday.
With the cold weather strating it could blow smoke all day.

Could the airfilter and intat have caused this????

No, more likely your oil cooler is probably partialy blocked, which causes the EGR cooler to go. It could still be head gaskets, does the smoke quit once it warms up? Is there any coolant in your oil? Or oil in your coolant? Once the dealer looks at it , if they say its headgaskets, check with them to see if they would install ARP headstuds for you. It would be an additional cost upfront ('bout $500) ,but money well spent to avoid problems in the future when it's not covered by the warranty anymore.

 

Dude 72000 miles is not 183,000km

72,000mi ~= 115000kms

 

Diesel engine warranty is good until 160,000kms

Or 5 years from original Warranty Start Date

 

Thank youI am calling the dealer thismorning. Will a stop leak product work as a quik fix until I am able the get it in for repair?

 

I would not add anything.(other than coolant as needed) Let the dealer look at it.
