Thats not what Im saying at all Keith, all these problems do need to be addressed for sure, but why is it that any cooling sytem problem will make the rad leak. I think there is a serious quality issue with these rads, that is not getting addressed by ford or the manufacturer. They just keep giving us the same crap to put back in. I often wonder if the mounting design has something to do with it. With the weight of the core with coolant in it "hanging" from the plastic tanks, then introduce body flex and vibration. How many rads have we changed with non of these other issues present?

Thats kinda the point of my post. First it was the backflow of gass buildup causing rads to fail, then it was bad thermostats causing temperature/pressure fluctuations causing rads to fail, now its low coolant levels causing rads to fail. Will they ever admit that (some of these) rads just fail? I have seen A/M all aluminium rads in 6.0l trucks, I wonder if or when they might be available for 6.4l trucks.

I have seen replaced head gaskets fail twice. One had a banks 6 gunn kit, and got studs at first gasket replace, around 60,000kms, redone at 120,000kms.(scattered the motor at 140,000kms) Second had an edge juice, got stock head bolts on original gasket job, around 100,000kms and was redone at 240,000kms.

Looks like you wont be diaging anymore oil leaks!!

Your gonna need a palet, not a box!!!!!

So, the tsb for thermostats causing rad failures is gone, as the latest recall calibration includes a t-stat monitor. Has anyone seen the latest tsb for coolant leak? Check for leak at radiator hose connections. If leak is present at either hose, replace both hoses, repalce radiator and flush and replace coolant. Apparantly it is now thought that low coolant levels are causing rad failures. (and here I thought rad failures were causing low coolant levels?)

Trans is the only cert I dont have, and dont really want it, for this exact reason. We do very little trans work at our shop, half a dozen a year (major o/hauls) maybe. Way too many trannys in warranty right now to stay current on.

Check your maf sensor as well, the old 5.7 vortec in the pickups would hesitate and stumble with a dirty maf sensor.

Check your maf sensor, It is vital in the calculation of air entering the engine, which I beleive the pcm uses with the pressure reading to determine dpf loading at all states of engine operation, not just high speed and load. If it is giving an impropper reading, dpf load calculations will be out to lunch.

Possibly a broken intake valve spring?

I did the same as Greg.

This week feels like I work at a speed shop, not a dealer. Monday installed 8 psi procharger on 2011 6.2l raptor. (That is a fun motherf*$cking truck to drive, over 600 hp) Yesterday put southbend clutch in a modded up dodge diesel, today diaged clutch problems in a modded 09 gt500 (675 hp). Then today was back to reality, drilling out broken rh side manifold bolts on an 08 f550 6.4l finning service body. Truck is too heavy to lift on any hoist, so I spent half the day on my knees.

I've also heard that as well Mike. Maybe bump the engine over a bit and air test again, to see if moving the hp pump pistons has any effect on the gurgling? Every hp pump I have changed has been a catastrophic failure, so I have never done that test.

Yesterday I rebuilt a mangled convertible top on an 05 mustang. I'll take any diesel engine job over that anyday. One side rail broke and caused the other to pile up catastrophicly. Both side linkage/rail kits later and its alive.

There are a few guys talking about this on the canadian protech board as well. Hopefully not and epidemic......

Back to the whats in your bay..., today was a strange one. Inspected a 95 f-350 last week, ex-bush truck with 280000 kms. It needed a tonne of work, guy just bought it and wants all the work done: front calipers, broken front wheel studs, clutch master, oil pan gasket, front crank seal, broken up exhaust, alternator, belt, broken egr pipe, leaking rad, broken rad support, broken headlights and signal lights, seized park brake cables, rotted battery cables. That was my project for today and a bit of tommorow. Been a while since I worked on one of these old rockets. To top it off the box is all broken up and literally falling off the truck, he wants us to find him a used box now. For what he is spending in repairs he could buy a way better truck! People are Crazy.

This is a must watch. Our GM sent it to me a while ago. We all have had a customer or two like this I'm sure. http://www.xtranormal.com/watch/7452561

Did you notice how they are blaming the p164a on excessive idle time during cold weather? Every one that I have looked at freeze frame shows it was on a decel.

Too bad they didnt assemble "kits" like that for more big jobs, especially on the 6.4s. Save alot of time at the parts computer for sure.

^^^^^Now that right there is cool.^^^^^^ The motorhome one, not the busses.

We have our shop computer hooked to a stereo unit, several speakers throughout the shop. Mostly listen to cj92 ( rock, old and new) out of Calgary, the odd time koolfm or jack fm from calgary as well.

When was the last time you heard a doctor say something bad about another doctor?

Pictures?

No doubt! Had another one towed in today, wrench light on and reduced engine power. Had the recall reprogram the other day. P00B7-engine coolant flow performance and P012F eot / ect correlation. Ended up needing a thermostat. They are definatly trying to make these things "save themselves".

Apparantly this new flash works. I had a P242F (engine oil overfull detected) Drained 22l or so. Turned out to be an injector PUKING fuel out of the injector body, where the 2 peices fit together. This truck had 7 injectors replaced on fsa 09B08,(for potential leaking injectors) when it was almost new - 15,000km. (110,000km now) The one that leaked was the only one that was not (required to be) replaced when the FSA was performed. I am now wondering how they determined what injectors were to be replaced and how accurate that system was? On a side note, when I submitted for prior approval for 1 injector, they wrote me back and said, since this truck falls in the build date range of FSA 09b08, It is reccomended to replace all 8 injectors. I checked, FSA 09b08 expired in march of last year, And was already performed on this truck. Just to be sure I re-asked for clarification, that they wanted all 8 changed, even though 7 had already been claimed, and to claim it under 09b08? Apparantly they were asleep at the other end, they quickly appoligized for the oversight, and now only want 1 changed. I put 6005PA on twice, but I doubt they'll pay it.
