Just had oil cooler and egr delete and the delta is as stated above. The head gaskets are gone not bad just pukes a little. Going to have heads done next week. I think that spread is way to high at 70- 75 mph. Just wanted more opinion on the spread. Thanks a head for any input!!

 

Mark my cooler is year and a half old and i see 10 to12 all the time , i just live with it. Hell my friend has and 04 never had coolant changed he's at 110000 or so and when i put my scangauge on his truck and had no more than 3 or 4 diff made me sick.

 

did you do a good job and very thorough cleaning and flush of the system? it sucks but people have had ir reclog very quickly... dont be too upset im at 25+ on long hauls on the highway unloaded... ill be doin mine soon ... once i do an injector or whatever else is making my truck run like sheeet like it is

 

first off get some vc9 and flush it again. replace the oil cooler again when the heads are off.
from there I would still put my egr valve in and plug it in it wont do anything but take up space and possible keep the pcm on the happer side.

 

Thanks for the input, didn't do the flush on the last repair. But will it hurt to before she goes back under the knife HG & oil cooler to drain whats left of the coolant replace water and vc-9 X's 2 for three to four days?? It doesn;t get drivin that much as long as I'm not in the pilots seat

 

I would not leave a boiler cleaner in my engine for more then a few hours. I would do the flush and then reuse your old coolant for the time being.

 

Ya they say vc9 shouldn't be there over 3 hours...
They say not to but run the vc9 in there for an hour or two then flush it with the hosefor a while and make sure it's alll out and then go back with old coolant if only for a few days...
To be honest if I were doing hg and oil cooler I'd probabl go ahead and remove the radiator and have it cleaned at a radiator shop... Just for piece of mind... But you should be good then

 

What are your actual ECT and EOT numbers? If your thermostat isnt functioning correctly, it can throw your oil/water delta off as well.

Just a thought.
