Finally finished my routine valve cleaning method vid;
FWg_A
I am putting the vid somewhere that will allow me to post the vid in this post.
-
Also, I am aware this in no way does a thorough complete cleaning of all carbon build-up.
But I do this every 10k miles and yet have not had random misfires at/up to 92k miles.
It will clean the intake valves and seems to slow down future build-up. I do want to get a lighted micro-scope cam to take a look in the future at the before and after. I hope it is not too long before I do that so hang on. First I will try finding somebody that has one for borrow...

Thanks. Nice locale for this stuff to be, yes?
-
Great vids fella, well done and will definetly be useful.
:happy2:
-
I'd be surprised if this method shifted the build up but I'd love to be proved wrong. Post up some before and after pics if you get the camera :party:
-
Yes, and BG44K has one out there somewhere. Their product is mostly mineral spirits. I would love seeing if my difference matched their filmed results. If nothing else, to just see if and what the difference is for myself. Whatever I'm doing is working so far at keeping the misfires at bay.

Great Vid once again Brad :congrats: :congrats: :congrats:

Thanks. It is something easy enough to give it a go on some sort of scheduled mileage increment to help with that build-up. Most of the intake valve cleaners out there are some % solvent, some % oil, and even a small % alcohol in a few. 100% mineral spirits or kerosene should be 100% solvent strength of bg44k and seafoam respectively.
-
Is there a danger that you can hydrolock the engine doing this?
-
You would need to inject alot of water to hydrolock an engine.
Ive done this to quite a few previous cars, steam cleans the cylinders and the water turns to steam.
When running water injection you get a similar effect
-
I highly doubt it. Mineral spirits is a solvent and does not dry fast/cool fast.

Here's one result vid;

Here are today's valve pics. Impressive the amount of carbon removal this does.
The valve stems look nearly free of carbon, and the valve stem guides show their bronze again.

The video doesen't work....

Apologies...I do not know why the address differs now. Try it now... it is a fresh copy + paste :drinking:
Also, you can be creative with your own spray method including selecting your own product and delivery canister.
Just be sure to completely seal the space in the IAT port if your canister comes with a small diameter dispensing tube. Drilling a small hole through a small rubber cork that fits the port will allow for use of a prepackaged product.

Can you confirm what solution you use and how much of it. Thanks

I use 1 part fuel, 1 part NAPHTHA(quick drying solvent), and 2 parts white spirits...at least 16oz minimum.
Here is a new vid I made showing the mixture and my sprayer mods: FWg_A

This looks awesome! Where does the carbon build-up go? I've seen in your video it appears to come out of the exhaust. Could this cause any damage to a 200 cell sports cat?

I did this when my exhaust was stock and when I had a 400cell ceramic cat. So it does pass through the system safely...at least with mine, and I haven't heard of any horrible tales. I am catless now and there is never carbon debris on my concrete following this procedure...so it must burn quite thoroughly during combustion.
