Can I change my front timing cover to a newer model?

[Arcticfury]

Hey Guys,

Can I change my early 04 6.0 front cover to the newer (100 MM) style? My truck runs hot when I pull in the summer and I just bought a toy hauler. I don't want to have any problems later. I have looked into this and see that there are two styles. One that the outlet comes out at 4 o'clock like mine and the mid release 04 ones and the 3 o'clock ones that came out in 05 thru 07. Would I run into problems if i installed the 3 o'clock style? Any help would be appreciated Thanks.

I have already changed my Oil cooler and deleted my EGR. Flushed the whole system with restore and VC-9 with a reverse flush. Upgraded to ELC coolant.

IIRC, yes you can switch to a newer style front cover. I just don't recall all the details on what other parts are needed.

I have the early '04 model with the 90mm water pump, I have no issues with keeping the motor with in temp when towing.

What are your symptoms? Overheating? Temp fluctuating? What are your coolant temps towing and not towing? OEM thermostat or store brand? The more info the better.

Thanks

My temps unloaded run from 190 to 200. When I use the truck to pull the temps rise. during a grade they spike at 220. My oil temps run higher by 10 degrees. After the grade the temps drop. What concerns me most is during the climb my engine will de-fuel dropping my boost to 4. If I push the pedal to the floor to make the trans down shift and bring my RPM up the truck cools down and the boost returns. But as soon as I back off the temps rise and i could/will lose my boost again and it feel like it de-feuls again. Very annoying. If I could run up the hills at 70 mile per I would be fine lol.

I have found a 05 timing cover down the road but I can't find a late 04.

I also had my head gaskets replaced and put in studs.
New ford thermostat.

Again thanks for the response

By what temps you posted, looks very acceptable when towing.

Defueling is not only based on coolant temp, there are other temps that the PCM takes into account that will cause your truck to defuel (limp mode).

[Arcticfury]

what other reasons would cause that?

I really haven't towed anything as heavy as my toy hauler yet. I pulled my snowmobile enclosed trailer 5000 lbs in the winter to get those numbers

[Lilpooh]

Could be several things, overboost, EOT too high, failed sensors. If you were to google "6.0 powerstroke limp mode", you'll get a whole bunch of reading material.

Your best bet would be to first check if there are any stored codes. Try to get a good code reader, all code readers are not created equal. Some of the cheaper code readers won't read the "harder" codes.

If you don't find any codes that could of caused the "limp mode", then I would suggest clearing the codes, and try using a diagnostic scan tool that can read live data and go for a drive with a load on, try to reproduce the limp mode while monitoring the live data.

[Arcticfury]

I will Google that for sure.

I have a edge monitor that i use to watch the engine. I get three codes most of the time. #8 glow plug, egr, and an unknown one.

I have checked and need a new GPCM for the first code.(as soon as I get some extra cash)
The second one is because the EGR delete
I will have to see if I can remember the last one, but i think it was from 4" exhaust. Maybe that is my over boost problem. I cleared it when I had my emissions done but I wrote it down somewhere.

Where can I get a tool to get live data? that might be the ticket to capturer the problem while it is happening.

Thanks for the help.

OK here are the codes

1-P0401 Exhaust gas recirculation flow insufficient
2-P0678 #8 Glow Plug
3-P132B Unknown

[Lilpooh]

The p132b could be causing the sensation of "limp mode", it's a code for the early PCM flashes. Sounds like you have a boost leak, exhaust leak at the up-pipe/y-pipes, or one of the corresponding sensors involved with VGT operation is faulty/dirty.

[Arcticfury]

Hmmmm

Now I'm getting somewhere!

I looked at the "limp mode" problems like you suggested and found one that sounded close. The MAP sensor. That would be on the air side. Right?`

I will look at my exhaust and up pipe really close. But why would it only do it during hot outside temps and while pulling heavy loads? I can pull my Snowmobile trailer up steep grades with no problems at all. But once the summer hits I have the de-fuel problems.

What other sensors would you look at?
