3.3TT Cleaning the intake valves with CRC

This is the vacuum line that I used...




....However, you may get better distribution by removing the cold side charge pipe (while keeping the coupling attached to reduce overspray), and then just spraying directly onto the throttle plate. This will also clean carbon deposits off the butterfly.

I ended up removing the surge tank/intake manifold to inspect the runners and valves, and noticed that the CRC cleaner left a substantial amount of oily residue all along the inside of the manifold. Cleaning said residue wasn't difficult, though. Anyway, if I were to do it again I'd just clean the valves by hand, and use the CRC spray directly on the valves (it dissolves the carbon buildup very effectively when allowed to sit), as removing the IM/ST is not difficult nor time consuming.
Is there any issues using the crc through the throttle body while having an occ? Or should occ be removed first before using crc?
 
I have used this product on my 19' Stinger GT1 and my sons 12' VW GTI and there was a noticeable improvement in how the engine sounded and ran. I will plan to do another round after 1k miles on these cars and also do the 1st round on my wife's 18' BMW X3 m40i and daughter-in-laws 17' Hyundai Elantra. So far I am happy with this product.

Did the CRC yesterday and before the CRC the car would crank for 10-15 seconds before starting now it starts right up, yet next time I will be removing the intake manifold and clean the valves manually it just feels more effective this way.

I have the ADD W1 V3 OCC. I empty it and wipe it down. Start the engine to warm it up, then remove the dipstick and spray into the hole. I do it before every oil change.

So you're adding the cleaner to your oil? I don't think that's the intended way of doing it.
 
He adds it to the dipstick in the OCC, then it gets pulled into the intake from there...not the oil dipstick.
Some OCCs have dipsticks some dont.

Oh okay that's makes sense. I did it the traditional way by removing one of the vacuum lines in the manifold, but if I'm being honest I would just get the valves walnut blasted and be done with it for 50k miles.

With my OCC catching blow by and the CRC I think ill save my money. When its time to get the plugs changed, Ill splurge and get the dealer to do it and take some pictures of the valves when the lid is off.

Where you sprayed it in did wear gloves? I find the engine bay gets nice and toasty as your spraying in the fluid.

I loosen the coupler and slide the CRC plastic hose into the intake pipe at this location this way the TB also gets cleaned:1693495504937.webp

CRC cleaner leaves an oily residue on the throttle plade and then dust will stick to it. Screenshot_20230831-113533.webpif you want to clean your throttle use this stuff.
