Easy way to clean secondary valves?

[Izzmo]

So, was looking yesterday and my primary valve air intakes are clean as a whistle.. but the secondaries are very.. VERY dirty.. coked with carbon for sure.

Is there any way to clean this?

I cleaned mine last night for 30 minutes in the hot tank

Remove the lower intake, spray with non-chlorinated Brakleen until they are clean, reinstall.

Hmm, just to make clear, I'm not talking about the intake manifolds, I'm talking about the intake ports to the cylinders (below the LIM)

I don't think your suggestion will work for that will it Mr. Anon?

"stuff a rag down there....spray, remove rag. Repeat as needed." -93rev2sev

Not a bad idea all said and done.. but I think the port holes are a little small.

Some say that's a horrible idea. What brand of tampon will you be using?

The 'right' way to do it would be to remove the head, disassemble, and hot tank. Then reassemble head and reinstall. (TIC):wave:

 

[Izzmo]

Yeah.. I know the right way lol.. but I was easy way

And... we don't have reusable head bolts... so... PROBLEM!

Actually.. didn't someone make a batch of the head bolts? I don't remember.

I know. Thank you for stating the obvious.:thankyou:

Sometimes, NOT disassembling everything might be the easiest option, and most trouble free. Don't take it apart, and it WON'T leak. And you won't need extra gaskets. And you won't need extra tools you may not have.

huh.

 

[Izzmo]

lol. Good point.

I would not have a problem with taking it all apart.. if I had the new gaskets and bolts to use.. ugh.

I like taking stuff apart.. but putting it all back together then... no way

Rock Auto has the gaskets and head bolts.

Idea off the top of my head.... Probably a big no-no



1)Close intake valves for that cylinder.
2)Fill port with non-chlorinated Brakleen and gently scrub the carbon off of the walls. 3)Soak the crap up with a heavy flow tampon and blow the rest away with an air hose.
4)???
5)Profit.

They don't list a head gasket and the bolts are for the 3.0L Duratec.

 

[Izzmo]

Ah damn.. I got all excited that someone made the head bolts again... damn

 

[SHOZ123]

Head gaskets are out there and the Duratec bolts can be shortened to fit. Or you could reuse the original stuff.

ummmmm seafoam ..........
i dont know much about the v8 sho's but cant u wire them a little open run the car a spray decarbonizer spray down the intake and after that just run some seafoam down the boster line into the engine while its running and clean everything up

heck its worth a try just trying to help u out

 

[Izzmo]

They don't sell that stuff anymore do they?

cold activated oven cleaner (valve's closed)

 

[Izzmo]

Woah... you haven't been on here in a while.. :hello:

So.. using this oven cleaner.. you just spray it in there (I assume spray it.. never used oven cleaner) and then let it sit for a while.. and then wipe it clean?

 

[midnightauto]

wear gloves and glasses spraying into a closed hole does blow back don't let it sit too long depending on the brand of oven cleaner (dollar store) 5-20 minutes should loosen the carbon for easy removal. I used a small hole brush (gun cleaning kit) to help remove the carbon. I used air to blow out the crap then used a water based soap in a spray bottle again dollar store (mean green orange cleaner) to finish and remove any leftover oven cleaner. cover all painted parts.

Nice, thanks for the information!
