Diesel Engine Intake Decarb

[Stormtrooper Junior Member Find all posts View Profile Close Stormtrooper]

GDay all.

With the seemingly endless, confusing and frustrating(for me anyway) talk, threads and counter arguments of EGR`s, plates, blanking, rattle, injector values, throttle valves and diesel particulate filters and the like (I am getting to the point..lol), has anybody tried and tested Liqui-Moly Diesel Engine Intake Decarb or the like?

Got an email from Supercheap today of it on sale. I have never heard of the stuff and have no idea where to even stick the nozzle tube to apply this stuff!!!
Here is the sales pitch.(I hope this is allowed!!) No I dont work for them or Super cheap.

"The Liqui-Moly Diesel Engine Intake Decarb is a high-tech solvent and additive formulation for rapid removal of typical contamination and deposits which can be found in the diesel intake and throttle valve areas. The decarb is designed to dissolve and remove all deposits and contaminants including; oil, resin, adhesive residue, etc. It guarantees operability of all moving parts and helps to reduce fuel consumption. Liqui-Moly Diesel Intake Decarb increases the reliability of diesel-powered engines and is suitable for vehicles fitted with EGR (exhaust gas recirculation) valve and DPF (diesel particulate filter)."

Does it work?

Will it screw my engine by releasing garbage to travel into the motor that would normally hug components?( Don't filters, traps etc be designed to "trap" and "filter"?)

Where is it sprayed/ applied/ concentrated?

Are there cheaper treatments, alternative cleaning methods for the Joe Blow to do at home without having a brain the size of Tasmania or the focus of a ninja on Ritalin?
I have $18.95 to spend on loyalty my card. I think the product is $30 a can. So its either the can or a cheap buffing machine.

Happy new YEAR members. (Is it too late for that?)
Cheers

My Mechanic just recommended it during the last service. He was impressed with how clean my engine was (soot out the back when the cleaner is used) and he pretty much emptied a can through it.

He took took out the intercooler bolts and pulled off the TB hose just enough to get the spray hose into the TB. Hold the revs at 2K I think it was and start spraying. He said its best to do it when car is hot too.

Car feels a little more responsive if that helps.

My problem with it is that you take all that crap through your engine and I don't like the idea of a big clump of that cr$p getting stuck in a valve or something. Maybe once you have done an egr clean and the 7mm restrict you could use it for maintenance.

Agreed.

Agreed.

That was my main concern.

True, our engine appears to have well looked after its whole life (Always serviced by Toyota with no expenses spared).

So I pulled off my intake hose today and discovered this:

I purchased some of the liquid-moly intake decarb stuff. It does have me worried though that if I spray the stuff in that some things may occur:
1. a big chunk breaks off and destroys something in the engine
2. The oil will become hugely clogged with carbon
3. How long can I drive it after before doing oil change
4. What codes will it throw

I wouldn't spray that stuff into the intake. Just do a manual clean of the throttle body and the elbow of the intake manifold. There is a guide here http://www.pradootech.com/phpbb/view...php?f=57&t=330

Delete the extra o after prado in the address bar for the link to work.

Well I did it today. My outcome is it did little to nothing.
And to top it off the worst happened. The little spray thing at the end of the nozzle (about the size of a tic-tac came off the hose and into the engine!!!!
Can't find it anywhere at all and pulling apart the manifold to find it is not an option at the moment.
The car ran fine after and has so for about 20 mins. I couldn't find it on the ground behind the exhaust so I'm hoping it got burned up!

Oh shit!! Has it turned up yet?

[JimmyC Advanced Member Find all posts View Profile Close JimmyC]

Still a no show. From all accounts it came out the exhaust pipe as a puff of smoke.

A few people have recommended me Lucas oil upper cylinder head cleaner. I just put 250ml in every tank... Not sure if it helps at all. But reviews say it does.

If it goes into the fuel tank it won't do squat. The fuel is injected directly into the cylinder, it doesn't go through the manifold. Whatever makes you feel warm and fuzzy though

I've said it before and I'll say it again. Nothing will shift that gunk other than hard scrubbing and scraping after disassembling the components. There is an abrasive putty that performance engine builders use to sculpt out inlet manifolds in order to get the flow happening. But, once again, it can only be used after disassembly.
