Whose car is the other one?

 

Ecaulks.

Gonna sandblast them anyway, watch number 2 be clean but 1, 3 and 4 be all gunked up lol

 

I still think running them rich like when that car was trifecta tuned and tuned by James gunks them up faster (more combustion deposits and more oil blowing by as things get dirty and wear) and once dirty you have to pull the mani to clean them well. Mine were clean as could be at 34K miles when I checked them. The other factor is how well seated his rings are and oil type (brand) used.

 

I had forgot it was trifecta tuned. I wonder if that does have something to do with it. I use Mobil 1 High mileage full Synthetic 5w-30.

 

Unfortunately for the first 32k of this engine i'm not sure how it was treated or if low ash oil was used. Compression test comes back good, but I havent had a leak down done. I think driving style has a lot to do with it also, short little trips spending more time idling vs longer highway drives at 2500rpms and higher.

 

Does anyone make a tool like they do for bmws/minis?

Could be a lot easier for cleanup.

I'm going to have to tackle this job soon. Getting bad hesitation in boost and during startup.

 

Duct tape a 5/16 line to your vacuum that helps with controlling the material coming out of the runner, the tool would cost more than it's worth just cover everything

 

My thought is to 3D print something to spray and vacuum at the same time. But I don't have 3D CAD experience

I'm sure someone has dimensions of the intake port on the head.

 

^^ It doesnt really matter. By the time you spent all that time and money developing a tool you could have done a kazillion valve cleanings.
Use a lot of duct tape and towels to isolate the port and a vacuum. The blaster will fill the port up soon enough, without a vacuum and you need to do it carefully, It takes about 20 mins total per port so just over an hour. It takes another couple of hours to remove, prep and replace, along with clean up. Four hours if its a first time job. GM cleaner helps for touch up. New gasket and valve helps. Eliminating the valve and running all the blowby ports through the Mann Hummel seperator works great for me. Just costs more time and money to do it.

 

Hi John,

If its a 4 hour job why are people charging 600$? Does the media cost that much?

 

Labor plus materials. You have to get equipment specifically for it and you have a mess to clean up after, thats not included in John's 4h. And John has it down since he's done so many, most shops would take closer to 5-6h due to infrequent blastings.

 

oil. filter. inlet manifold gasket. pcv valve. media is not a big expense at all. However, GM upper cylinder cleaner is not cheap . It is hard to get mobil 1 in canada for under 50 dollars to start with. Many times the inlet manifold is screwed up with gunk as well (especially LSJ) and that takes a lot more than an hour to do right, the air filter is dirty and needs replacing, and the throttle body needs cleaning.

service tools count for a lot and it takes a ton of clean up afterwards. Duct tape and laundry for the towels I use lol . I am not trying to justify the price, it is what it is, but as eCaulk points out, it all adds up. Tax in Canada is 13 % pretty much

 

Maybe this will explain why i idle rough sometimes...

 

could be, how many Kms dude?
John I'm loving the seperator and job you did on my valves, definitely worth it for imo

 

Mine did when they were dirty. At 32,000 miles they looked bad.

 

I have to get this done.. 135 kms on my car.. Getting the rough idle. I also am due for an oil change and have a set of new plugs.

 

Great time to do it. Good luck. Take your time and tape off everything you can imagine.

 

Is everyone just walnut blasting or does soaking it and cleaning it with picks also work?

I don't have any of the walnut blasting supplies.

 

I've heard they do both things

 

If you don't have the ability to walnut blast easy, then by all means get the cleaner and soak the valves overnight. I bought a set of picks and a gun cleaning kit with all kinds of brushes and pads. Worked pretty well.

 

Sweet thanks guys, guess i will order the PCV and Intake Gasket and go to town this weekend. Also have my CABs to do as well.

 

you can get a blast kit from harbor freight for a good price man.

 

Unfortunately we do not have harbor freight in Canada.

Is this the top end cleaner that everyone is using??

Yes or this

A lot of people like both.

Don't use on open valves obviously.

 

Also get a gun bore cleaning kit for the brass brushes and handles, those work great
