Why advocate one at a time when you don't know the history of his truck or if it's showing symptoms of having problems? He might even not know one way or the other if they are mild enough or he doesn't recognize them for what they are.

It is true that some don't have a very high risk threshold, sometimes that varies between what what you are talking about. I have a very low threshold on some things, but then I act like Evil Knievel on others.

 

Reward= less time & Money Risk=oem gaskets failing

 

Not really when gearhead claims to have a 1-3 mpg increase in mpgs with the SRL tune, In the end it depends on the driver, so im hoping for more power when i want it and better fuel economy when im taking it easy. Ill pick both thank you

 

You aren't getting them at the same time though, even according to you: "more power when I want it and better fuel economy when I take it easy". You are still picking one or the other.

 

You forgot another risk is you are out even more money and time if it doesn't work doing one at a time.

 

I run Innovative Diesels extreme street, the truck makes power so easy I have a hard time keeping my foot out of it. It will pickup a few mpg if you can have restrain.

 

since were gettin technical i kinda am because the SRL tune will be on. so it will provide more power through all the rpms

 

No you aren't. If you are showing restraint you aren't getting the full power the tune will give you. Even if you are calculating throughout the rpm range. The only way to realize both power and mpg gains is if you are able to utilize the full power of the tune and still gain mpg. If you have to show restraint, the tune isn't being used to it's potential. You are choosing to get better MPG over using the full power that the tune will give you.

 

You forgot another risk is you are out even more money and time if it doesn't work doing one at a time.

ok am I missing something here? assuming he does the work himself, how is he out more money if one at a time doesn't work.
if it springs a leak and he doesn't stop driving it yes. but like every other owner, if you keep on driving after a major failure its your own stupid fault.
more than a few owners have reported success at this, so I think we need to start giving it credit. likewise a good number of credible guys have reported running hot tunes on stock bolts successfully. they tend to be guys who are "nice" to the engine til its warm. also tends to make one think that many of the earlier HG replacement were actually misdiagnosed EGR coolers
just because someone is using some "restraint" doesn't mean that they are not still using more than stock

 

Do you not value your time? If I'm having to spend time re doing a fix then that's taking away time that I could be doing to earn money or do something else, spend time with the kids etc.

Do you get paid at a job for the time that you spend doing something? Time has value or at least it should. You put in time at work, do you not get paid for that, either salary or hourly?


Things aren't as cheap as a lot of people think, because they forget to value the time that they put into something. If I'm fixing my truck instead of using my truck to go to a horse show to earn money (either by teaching clients before they go into a class or placing (or winning) a class myself) that's costing me money. Or keeping me from doing design work etc.

Also, if one at a time doesn't work, he is going to have to go even further into the engine, because somewhere it isn't kosher. Maybe he has to mill the heads, something he should have done the first go around, more cost. Then the actually digging into the engine deeper is going to cost more in time, labor and both affect cost in the financial sense.

He has the original cost of doing the initial work of one at a time, plus all the extra work of having to fix it if he had something wrong with his engine that you wouldn't spot if you did it one at a time.

Could it work, yes. Is there a possibility that he doesn't have an existing issue...yes that is true. Can you say it with 100% certainty without digging into the engine, be very hard to. It's a gamble and it's a gamble that the owner is up on all the subtle clues that his engine is either clean or not. I am not saying that it won't work, but because even if the installation and everything goes flawlessly, you still run the risk of there being a problem with this method. While if you go check everything, dot your "i"s and cross your "t"s and the installation was flawless, you are good to go. I'm not saying it won't work, I'm saying your a gambling on that your engine is perfect (or within certain tolerances) right now. There is a difference.

 

I'm a believer in the one at a time, ill post in another 30-60k that its proof it works. You do a lot of extra work & achieve the same results, if you want to...

 

I don't really see any reason why the one at a time method wouldn't work as long as the gaskets are not already blown

 

That's the assumption that you are making, that they aren't blown.

It will work as long as nothing is wrong with the engine, however, you are making the assumption that nothing is wrong when you use that method.

I am not saying that it won't work, I am saying that it is a gamble, because you don't know the status of the engine's condition. Some times the clues to engine issues are very subtle that might be missed.

 

Well in my case after my coolant flush I filled slightly over the original full marks. To allow for any air pockets. I had my slide camper loaded, total weight of truck 11000. Temp in high eighties warmed it up put it on a mile of 5% grade full throttle full boost all the way. Topped out around 90 mph temp at 230the oil a bit more. Checked it cold afterwards no sign of any spitting. coolant still right up there. Pretty sure my HG's are OK. If it was gonna puke that should have done it.

 

For engines that will be pushed harder than average, I'm not sold on the one at a time method myself.

If there are any imperfections in the mating surfaces, the HGs can still go, regardless of what's holding them together. Without pulling the heads, you don't know for sure.
