Changed to Synthetic...now turbo whistles more

[toast]

Is this common? I used the Amsoil Engine cleaner, and then put in Amsoil Diesel /Marine blend. There is definitely more whistle than before, with no noticeable performance change. I also installed a pyro, but its not leaking, nor does it sound like an exhaust leak, just a louder turbo. Still have the stock intake and exhaust on...

I never noticed anything, maybe you're foot is just in it more? lol

I asked about engine flush myself and a few people told me not to use anything but oil in the crankcase, because of the HPOP system in our PSDs and the possible crud/junk getting up to it from the cleaner. I wouldn't worry about it though, just my 2 cents.

I'll probably need another change to get it fully synthetic as the Rotella dino oil that was in the HPOP system diluted with the Amsoil that I stuck in a few months ago.

I wouldn't use the engine flush on any diesel. The product is made for gas engines. How many bottles did you use. if you have some still in the HPOP it wouldn't be a good thing at all.

yeah i agree with dieselman, that engine flush might be diluting ur oil and that is what is making the turbo whine more. if ur oil is diluted with cleaner, it wont protect or cool the turbo like it should and u risk ruining the insides.

Well the bottle said to use the entire contents, which I did, and it also says to be used before switching to synthetic. It said to run the motor at high idle for 15 minutes, then drain the oil while its still hot, so thats what I did....

Another thing, my previous oil drain plug leaked, so I bought a new one, with a new copper washer, but it still leaks.....anyone have this issue? RTV the threads?

did you get a factory copper washer? I never have drain plug leaks. the bottle you used is for gas engines an is to be added with 7 qts capacities.

engine flush in diesel is not a good idea, especially psd with oil controlled injectors

Just my opinion here. I work on cars and trucks for a living and have been for about 12 yrs. I have never seen anything good come out of using an engine oil flush in anything. It will generally cause more problems than it will solve. I have had several vehicles come in that were flushed and now have an oil pressure problem. Usually find that the flush didn't remove, it just loosened the sludge and oil deposits. People drained the oil and followed the directions on the bottle. What I foud after they done this is all of that stuff that broke loose ended up in the pan and then stuck to the pick-up screen on the oil pump. Again, this is just my opinion and what I have seen. Just wanted to throw out a little bit of caution and my own personal experiences to ya. Good luck with getting it figured out.

I would generally agree with you 100% I had bad experience with flushes before.
But the product we are talking about is alone in the market place as far as flushes go, I have personally done over 80 vehicles with Amsoil flush and never had an issue with one, including diesels. generally diesels dont sludge up as bad as gasoline engines, I tend not to worry about doing the flush in them.
Now your information would be very valid in an engine that is extreemly dirty and I would have second thoughts of using a cleaner, what it would really need is the pan and screen removed for cleaning.

a cleaner turbo is a happy turbo, did you notice any extra boost or quicker spool up? I have had great results with the 7.3 and Amsoil AME blend

This drain plug is quite irritating! I just verified that its at 28 ft/lbs. The plug, and copper washer were bought at autozone...
