She's a smokin!

Hey guy just wondering if you guys can give me some advice on my 04 f350 6l as mech/dealers are no dam help!
My truck has recently started blowing white smoke
I've bin doing a bit of research and believe I need to replace egr cooler and oil cooler, but what I need to know is
Is if I go with a egr delete kit do I still need to replace the egr cooler or is the egr delete just to replace the egr valve? Sorry if I sound like a dumb a** this is my first diesel, also is the oil cooler a cab off job?
Something I can take on myself I feel I'm fairly mechanically inclined just don't know what this will involve quite yet I will have to do a little more research before I get to the teardown.

The egr delete replaces the egr cooler,and the you can do the oil cooler with the cab on.

A egr delete will remove the cooler always. You can leave the valve in for looks but the exhaust flow will be blocked.

Rite that's good news deletes are cheaper than coolers that's forsure now you guys have any tricks on how to check if my head gaskets Toast with out doing a leak down? I know we used to cold start our gassers and remove the rad cap and if it starts showing air bubbles then the gaskets smoked but I don't know if this is the same with diesels

Also forgot to ask is there more than one Oil cooler internal&extErnal? If so how do I know what one to change or do I do both?
Thanks guys this is a great forum

White smoke, and I'm willing to bet your HG's are already toasted. Check that by seeing if your coolant system can maintain pressure.

I've got a lot of information on this in the following thread:
Write Up: Bullet-Proofing the 6.0L PSD.

If you managed to catch it before the HG's went, its a day job with the cab on. Very doable for owner if you do the research. If you've blown gaskets, do the research here find out exactly what you want to accomplish with bullet-proofing this motor. Do the job once, do it right, and you won't have to do it a second time.

There is only one oil cooler on these trucks, and its design leaves much to be desired. Your option is to rebuild it proactively before failure, or upgrade to an external air-to-oil cooler from Bullet Proof Diesel.

Any further questions let me know, I've been down this road before. Also, I don't recommend the EGR deletes as much anymore, with the emissions laws getting tougher throughout the country. BPD sells a solid upgraded cooler, that allows you to not worry about replacing it again, and the law off your back.
