Intake valve cleaning

Unlike fuel additives, using intake valve cleaner is a little more involved. First, you must remove the air filter and locate the MAF sensor. The MAF will be between the air filter and the throttle body on the engine. You DO NOT spray this in front of the MAF, as it can damage the sensitive device. North Shore Motor Werks intake valve carbon cleaning service.

The buildup is usually significant by 50miles. Removing the cylinder heads and doing a valve job. Chemical cleaning of the intake system. We usually do the carbon blast on vehicles that have the intake valves accessible with the intake manifold remove and chemical cleaning if the valves are not accessible. Without gas washing over the valves, as it does in conventional (PFI) engines, carbon builds up quickly on the backs of GDI intake valves.

This leads to reduced power and performance. Installing an OCC (Oil Catch Can) can help prevent some of the carbon build-up, however cleaning is still necessary every ~60miles. If you are planning on removing the intake manifold and or injectors for any reason you should set aside time to clean the intake valves. I did a search but was unable to find a specific write up to our trucks. It was easy to disconnect the PCV hose and then I covered the hole with some tape and poked a small hole in the tape for the wand from the can to fit in.

The job of an idle air control valve is to regulate the car’s idle based on how much air gets into the engine. This is done through the vehicle’s computer system and then sends the information to the components. If the idle air control valve is malfunctioning, it will cause the engine to idle rough, too low, too high, or irregular. Next, spray the power foam on the throttle valve and then, clean the excess liquid on its plate using the cotton cloth. Finally, attach the air intake tube to the throttle valve.

Like throttle valve , the vacuum hose is also first detached from the inlet manifold. It catches the oil before it gets recycled through intake this oily film is what ends up causing carbon to build up on the valves because no fuel is sprayed inside the intake ports hence no detergents are cleaning them so that is where the carbon comes from. Carbon cleaning is performed port-by-port, with the engine rotated so that the corresponding intake valves are closed. There is a price to pay for the performance advantages of direct fuel injection! Direct fuel injection allows automotive manufacturers to increase fuel mileage, power and efficiency.

CRC GDI IVD intake valve and turbo cleaner is an aerosol spray that’s applied through the engines air intake or throttle body and delivered directly to the backs of the GDI intake valves.

CRC GDI valve and turbo cleaner contains the highest concentration of PEA available on the market to provide the fastest, most thorough chemical cleaning.

On most engines, the intake valve already starts opening before the exhaust valve is completely closed.

During that overlap perio the intake manifold’s vacuum can suck exhaust gas backward into the intake manifol especially while idling. FREE Shipping on eligible orders. Severe carbon build-up can cause several issues such as rough cold idle, hard starts, decreased acceleration, misfires, black clouds under hard acceleration, and the illumination of the check engine light.

Repair of this condition once severe requires the physical cleaning of the intake manifold and intake ports on the head. Scrub intake valves (no extended soak time required). Remove dirty solution with Mityvac or similar vacuum tool.

Rotate engine until the valves of the other cylinders have close then repeat Steps 6–on these intake chambers. If valves need further cleaning , repeat Steps 6–14. We sifted out the walnuts vacuumed up after the procedure and recovered all the carbon (quarter for size comparison) All this was blocking the intake ports. To perform the intake cleaning process, the intake manifol EGR valve , EGR cooler and all connecting pipes must be removed. This is a fairly straightforward process once the plastic engine cover is removed.

The intake systems are all similar but there are slight differences between models and engine codes. Intake valves and ports before cleaning. This will also help remove carbon from the intake valves.

Seafoam is another popular product for this purpose. Or, if you prefer, take your car in for a carbon cleaning service. The down side is the lack of fuel spraying on the back of the intake valve.

This removes the cleaning effect port fuel injection engines get, a real benefit new engine designs need. Add in a crankcase breather and oil vapors, and you have a real problem. Pre intake valve cleaning symptoms: At about 50miles, the motor began intermittently misfiring at idle. It was subtle and barely perceptible at first, but I noticed it.

I initially thought it was a bad ignition coil or something. In extreme cases the intake manifold is removed and the carbon is blasted off with a special injection system that uses walnut. About months ago (at about 70miles) I have multiple misfires so I replaced all coils and spark plugs. The car went smoothly up until a few.

Did this valve clean yesterday. It is the easiest thing in the world! Thanks a million to dsire on vwvortex for posting this! FSI engine but could be easily adapted to others.

For everyone who is interested in what actually goes on during a special intake valve cleaning , here is some more information along with several other detailed photos of the process.

Ask the Car Guy: Walnut Blasting and Carbon Build up “I went to the dealer because my car was acting sluggish.

It had lost its get up and go and it only had about 60miles on it! This mist of gasoline actually helps keep the intake ports clean. Manual cleaning with a brush and.
