Walnut blasted my intake valves

[JgenG]

Finally got my intake valves walnut blasted. Did it after 100200 km and the carbon build up was pretty significant.

$475 CAD. Did it in a shop in Toronto. Got the gaskets changed too. Although they weren't too bad

Thanks, I am sure you feel a difference and better fuel economy.

I didn't feel anything out of the blue before I did the walnut blasting, but after I definitely feel the smoother acceleration

How often do you change your oil?

Smother acceleration is always a good thing.

What grade of fuel do you use?

You had a lot of carbon for only about 60k miles, got me concerned about my valves.

Yeah that has me a little concerned as well. I've got a long way to 60k but not looking forward to pecan blasting...

I will remove my intake manifold and use CRC carbon cleaner that dissolves carbon to clean my valves/intake chambers with a brush added to scrub the stubborn areas. However, walnut shell basting does work well if I was going to pay someone to clean my valves.

The valves seem pretty easy to get to on our engines, however I may have to manually turn the engine to keep the valves closed while cleaning to prevent carbon chunks entering the combustion chamber. I am curious if the engine has to turned during walnut blasting.

However, after looking at this video I may just a use brake cleaner to breakup the carbon since it did better than CRC on cold engine parts.

I use the mid grade fuel . 89 octane

One more question, Are you doing city driving or highway? Or both? I apologize for the questions! Just trying to get a feel for things. Thanks.

Thanks. I do not know if the grade of fuel correlates to the amount of carbon build-up, but it helps me compare later on when I inspect my engine. I was going to wait until 100k miles, but I may just clean my valves at about 80k miles when I change my spark plugs since it easier to turn an engine when the plugs are removed.

I do both about 60% city 40% highway

Thanks JgenG for your time and your answers to my questions! I appreciate it..
