Ciaka, dont do seafoam for porsches, use Liqui-moly engine flush.. its designed to be much safer on the german type seal material and on european turbos.

 

Alex, what exactly do you mean in this statement ? "CRC intake valve cleaning'

do you mane this stuff?

 

Yes Sir!!!! You got it! Its tried and true for the Panamera Turbo's and V8's particularly. For Panameras, what you do is unscrew the two pins on the throttle body and then pull off the rubber y-pipe partially and have someone in the car keeping the RPM's at 2,000-3000RPM.... short bursts work the best, and you spray the entire can. It works REALLY well.. the engine will smooth out dramatically and you definitely feel the HP pick up too.

 

Thank you. Will have to give it a try

 

So what does the liquid moly engine flush do? Clean out direct injection valves that are gunked up?
Just to understand clear, I loosen throttle body t pipe and spray in while car at about 2k rpm?
How long do I take to spray in the stuff?
Where do I get it? Really want to try.
Have u seen if cleans valves well? Thanks sir.

 

So the difference between the Liqui-moly engine flush vs. the CRC direct injection valve and turbo cleaner is that the liqui-moly will clean out all the gunk build up from your Mobil 1(stock oil).... There is a lot if youve hit the 60K mile mark. That cleans up all the gunk in the valve cover, engine oil pan, and all the ports... It make a huge difference! You would do that before the oil change. If you werer to switch over to full synthetic oil, it would do this too, but over time such as using (motul or liqiomoly engine oil). For CRC intake valve cleaner, which you can get at any automobile parts store, you spray that directly into your intake manifold... I will post up a DIY for this later today... However, its quite simple... Just remove the two plastic pins for the ypipe, but dont remove completely so that the map sensor can still detect flow.... Then you spray the entire bottle in in short spurts and foloow the directions on the bottle. You'll notie a difference right away... however, after driving the car for a week afterwards, it REALLY makes a HUGE difference! Followed by a throttle reset/relearn. I got to take photos and it did make a huge effect. In the youtube videos that you see as examples, those are REALLY bad caked on valves.. nothing even close to ours... Id say, after two complete treatments, you'll have brand new, clean valves like when you bought the car new... you can do it today even...

 

it takes about 5-8 minutes to complete nearly the entire bottle..... Save like 25% of the spray so that you can do the same treatment into the turbocharger intake side.

 

SUPER SAFE.. as long as you dont spray your MAP sensor , lol. You'll feel the big difference after you've let the car dwell for an hour and then take it on the highway for 10 minutes... The higher velocity drivung on the highway will blow out most of the gunk thats left on the valves... once you get back home from that and let the car idle, you'll notie a huge difference..... Cleaning the Map Sensor with the map sensor cleaner by CRC is also a smart move right here...you'll get your throttle response back

 

So, ive become an official Panamera specialist in OC/Socal and have been servicing a bunch of panameras as a side hobby... and ive done this to every car with great success... a total of 18 panameras so far

 

So how exactly does the liqui moly stuff you just put into the engine oil, am I correct?
This would be different from the crc direct injection cleaner, which is sprayed into the intake via a small crack you create by partially sliding throttle Y pipe out (or I guess I could do this by removing one of the intake air tubes, rubber ones with metal o clamp, yes?).
I thought the liqui moly stuff is a spray too. Yeah. I may try that before an oil change. I did hear from others that doing engine flushes sometimes created issues.

As to the CRC direct injection spray, how exactly does that work? Does it get deposited on valves, and heat dislodges the gunk? Would that not create issues if it falls into the cylinder cavity?
Thinking out loud. Thanks.

 

Here are links to the products I found. I hope it is them, as related to discussion on cleaning valves and engine.



CRC Direct Injection Valve Cleaner

 

So for the CRC intake valve cleaner, the method of action it takes specifically is that it makes the carbon buildup into a looser state... The PEA is the main detergent in the chemical make up works to attack the carbon build up further when it is heated up. You dont have to worry about anything getting lodged between the valves or anything like that because the chemicals purpose is to desolidify into a gel-like suspension. The key part that really takes off all the gunk is the highway miles that you do after the first day of doing the treatment. The PEA actually stayed stuck onto the carbon for a couple of days and it will continue to work through out the couple of days. As far as the liqui-moly engine oil flush, you just add to the oil and its purpose and method of action is that it acts as a lubricating detergent... Specifically for the panamera turbos and V8 models, if you got higher miles(+60k miles), you'll actually do some good in preventing any clogging at the bottom of the oil pan where the sump inlet sits. When you get good flow there, you'll have a very happy running oil system. Afterwards, drain the oil and let it drain out warm for as long as you can to get as much of the detergent out(but no harm done if you dont with ligui-moly). If you wanna be super ****, dump in new oil, let the engine cycle through and redrain the oil.

 

Although its not an issue, but after the one week after treatment and you havent had a chance to do a ***** To Walls full throttle run, then Id suggest pulling off the spark plugs and cleaning off the electrode tips with electrical cleaner(or map sensor cleaner).

 

So is that where you spray the intake valve cleaner? remove the y pipe off throttle body a bit and slide the straw from can into the intake?
Where is the MAF, been trying to look it up, cannot locate. Not good idea to make that wet.
