Bubbles or no bubbles?

[Aretoo]

I am going to look at buying a truck on Wednesday and had a question about the Bulletproof method of testing head gaskets and EGR cooler. It is a 2006 F350 with 104xxx miles on it. The truck body and inside is immaculate. I am taking mt Insight CTS to get a delta on it to check the oil cooler.

Here is my question, if the head gasket and EGR cooler are both good (which the dealer said they are because they tested them) will I get no bubbles during the test. Everything I have read about the test is assuming something is wrong (EGR, head gaskets, or puking). What should my test results be if there is not problem

Thanks for the help

Not sure if this will help you by Wednesday unless you can pick up the block chek locally but here is a post I had previously.

TINY BUBBLES....TINY BUBBLES...??

Thanks! I had read about hat before and forgot about that test.

I found one at Oriley's that they can have here by tonight, so I have one. Cross my fingers it stays blue. Although with the price of the truck I could dump studs and gaskets in it and still come out ahead!

Just plug the CTS takes about 2 minutes setup time, check ECT-EOT-FICM take it out for about a 30 minute drive doing 60-65mph after 2-3min on flat ground so if you work your engine under heavy load (WOT or on a hill with a load behind you) to test the deltas. If you are near a 15 degree delta without working it hard , you will most likely be over under an actual load. Mine on flat groung runs ECT 192-194* EOT 198-200* and the FICM should read 48-48.5 volts.

Thanks for the advice. That is my plan, I have been buying stuff for the truck I don't even have yet. You will be glad to know my first purchase was the Edge CTS, I figured I would then at least know what I was getting into with the truck I bought!

regardless of delta you HAVE to put a gauge between the degauss and radiator in line and see where it goes.

Get a fuel gauge with a reset button and a 3.8" Tee so you can check it often and reset it, like a tire pressure gauge. 0 - 20 would be perfect and needs to go at least 15.
