Mbl35 Posted March 8, 2010 Share Posted March 8, 2010 08 e450 been burping up coolant for a while but does'nt overheat. I think it may be head gasket issue. This thing runs non stop pretty much. Did anyone ever put a head stud kit in a eseries or recomend it? Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted March 8, 2010 Share Posted March 8, 2010 Well for starters you wouldn't have to pull the engine again for head gaskets. Quote Link to comment Share on other sites More sharing options...
DamageINC Posted March 8, 2010 Share Posted March 8, 2010 I will say that I've never seen an E-series 6.0 wipe out the head gaskets UNLESS it was a result of something more severe, like extreme overheating or a failed oil cooler or something similar. (Or someone with a tuner of course) If indeed the head gaskets are bad, I'd bet that there was a catalyst for the failure as opposed to just a regular old 6.0 TRUCK head gasket failure. On that note - if you're going have the engine out and the heads off, I think it's almost absurd to not at least OFFER head studs to the customer and let them decide what they want to do Dave Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted March 8, 2010 Share Posted March 8, 2010 I did head gaskets on an E350 6.0L that had a seized turbocharger. That is all it takes though less likely to occur in an Econoline. Quote Link to comment Share on other sites More sharing options...

Yea, I've never seen headgaskets go bad on a e-series. They are de-tuned compared to the F-series. Quote Link to comment Share on other sites More sharing options...
Mbl35 Posted March 9, 2010 Author Share Posted March 9, 2010 Our f series get the typical head gasket concerns, but we never have to pull heads for overheating concerns on the eseries just for those pesty rocker carier seals. Though this one in parrticular though got me wondering. It don't have any turbo issues. Were keeping an eye on it, next time it stops in i'll drive it good and probe eot to ect span and check into it furhter. Quote Link to comment Share on other sites More sharing options...
Mbl35 Posted June 4, 2010 Author Share Posted June 4, 2010 Reviving this post because this thing rolled in yesterday for an a/c concern. i got a chance to check the eot to ect. They are like 7 deg. apart and this things been running all day in the heat. The bottle was below half full and the the medics say it don't overheat. This thing almost never shuts off exept whrn it comes in for service. Could it be that due to the fact that it's constantly running and on high idle alot that the cooling system pressure is a bit higher than normal?

Bruce Amacker Posted June 5, 2010 Share Posted June 5, 2010 Reviving this post because this thing rolled in yesterday for an a/c concern. I got a chance to check the eot to ect. They are like 7 deg. apart and this things been running all day in the heat. EOT/ECT difference means nothing unless you're going down the road either with a load or on the highway. As soon as you throttle down these two numbers nearly parallel. I've never seen a 7 degree spread on the highway, always more, even with a new cooler. The bottle was below half full and the the medics say it don't overheat. This thing almost never shuts off except when it comes in for service. Could it be that due to the fact that it's constantly running and on high idle a lot that the cooling system pressure is a bit higher than normal? Yes, that will cause a bit more coolant pressure, but not enough to cause coolant burping. Are there any other complaints, like coolant loss? I'd "tee" in a coolant pressure gauge and go for a hard run. If the coolant pressure jumps up under load, it's 90% head gaskets and 10% EGR cooler. You'll be able to watch your temp spread, too. Another bullshit test you could run quickly in the shop is a coolant sniffer (blue liquid type) in the bottle while someone power brakes it. This might show your problem, too. Good Luck!

Aaron Posted June 5, 2010 Share Posted June 5, 2010 One I just did, the MGP and the PVT (tied into the degas hose) fuckin' near went up TOGETHER.... I had to PRY the heads off the block once I had all the bolts out, and the gaskets were burned to the head and block. Quote Link to comment Share on other sites More sharing options...
Mbl35 Posted June 9, 2010 Author Share Posted June 9, 2010 It came in this morning for a pm service. I popoed the hood to check the bottle and it was 1/4 full. I filled it to the cold fill line and did the combustion leak test, the test fluid went from blue to dark green in less than a minute. I put the radikplusa on it and only builds up 16hg vacuum and drops to 14.5 and holds steady. I then pulled the egr cooler pipe to have a look and was dry. I then took it for a nice ten mile hard accelerating drive in the sun and the highest degree difference between ect and eot was 13 degrees on the highway, but most of the drive it was like a 7 to 9 degree difference no matter how hard i got on the throttle. When i got back to the shop i popped the hood and coolant was bubling out of the degas cap, little by little i vented the pressure out by cracking the cap a little at a time and you could see a yellow bubly substance but not oily. Kind of looks like the left over residue after you just cleaned the cooling system for a mixing oil cooler. It has'nt had that foamy stuff since march when another tech flushed the cooling system out. This never had an oil cooler done before. This is weird, it's not overheating. And the weirdest thing is that i did the combustion leak test again and the fluid stayed blue . When i fix my blackbery software, i'm gona post pictures of the soapy residue.

mchan68 Posted June 9, 2010 Share Posted June 9, 2010 Don't be insulted. After reading, and re-reading this entire thread, I don't think I read anywhere where someone suggested this so I will. Does the fan clutch work? Did this vehicle set the P0528 and/or P0480 DTCs? I've had more than my share of E-Series trucks where the fan clutch was either left unplugged or inoperative, causing the puking issues.

Mbl35 Posted June 9, 2010 Author Share Posted June 9, 2010 No, this one is fine. Has no dtc's and we get plenty like that to . Quote Link to comment Share on other sites More sharing options...
Mbl35 Posted June 10, 2010 Author Share Posted June 10, 2010 Mike, it don't set fan codes or any codes. It has a yellow sudsy substance oozing from the cap and it never overheats. I was thinking of letting it go for a few days with the coolant level at 1/4 full in the bottle and see what occurs. Not sure what to make of the sudsy coolant, trace oil mixing? I just got one before, 05 e350 box, it had a wrench lite on tuesday but not on weds and no evident drivability symptoms. P012f eot/ect correlation and p0404-passes egr test. The bottle's not puking but it is expanding. I drove it good and 20 degee dif between the eot and ect, problobly going to need an oil cooler and egr cooler rite? The temp needle stays in the middle. Pcm is at the latest. Oh boy, the other tech whom shares the drivability and diag work with me is out sick and will be for quite a while and i'm overwhelmed with sick sixes and other stuff.

Aaron Posted June 11, 2010 Share Posted June 11, 2010 Had one with 42 degrees spread on ECT/EOT this week -- no gauge concerns. Wrench lamp on. Quote Link to comment Share on other sites More sharing options...
cbriggs Posted June 12, 2010 Share Posted June 12, 2010 Yeah, Ive seen 40 before. The coolant should smell good in that one for ya! Quote Link to comment Share on other sites More sharing options...
DamageINC Posted June 28, 2010 Share Posted June 28, 2010 I know that, even without an excessive ECT/EOT spread, a bad oil cooler can still cause degas bottle venting and coolant burping as symptoms. I don't recall the exact reasoning behind the problem but it had something to do with the coolant forming gas/air pockets within the cooler and excess pressure as a result, which leads to intermittent loss of coolant out the bottle. It's also possible that you've just got a bad cap, hehehe.. Dave Quote Link to comment Share on other sites More sharing options...
Mbl35 Posted July 2, 2010 Author Share Posted July 2, 2010 Caps been changed. The heads are off, cyls 3, 5 and 7 are blown out pretty bad. The compression rings are gone on the bottom next to the water jackets. Quote Link to comment Share on other sites More sharing options...
Mbl35 Posted August 28, 2010 Author Share Posted August 28, 2010 I got it completed on monday and drove it 190 miles over 3 days. The bottle is nice and dry no more burping. The coolant stays at the fill line. Quote Link to comment Share on other sites More sharing options...

Keith Browning Posted August 31, 2010 Share Posted August 31, 2010 Product what ivity?????????? I'm a diesel tech thank god I got a guarantee Same here but I am always mindful that I need to earn revenue for the company and I do have some good incentives I rarely break 40 but I always try. If I had a van in for head gaskets it would be a wash. Lastly, our service department is still in agreement not to perform head stud installations for the simple fact that we would then own the engine. We recently had two trucks in that were tuned and now have leaking head gaskets. One turned away and the other I am finishing up on a cash ticket. It's his second set. It is all wrapped up and all I need to do is drop the cab when I return from training on Wed. My productivity is generally killed y being pulled from the job many times or distracted. Bet I don't finish it the day I return. Quote Link to comment Share on other sites More sharing options...
