Hey guys, i picked up a y8 longblock the other day and am planning on swapping just the head onto my y7. i figured while its just sitting here, i might as well clean it up, especially the carbon buildup on the exhaust runners and on the bottom of the valves and stuff.
i was recommended to do the following:


Detergent (not liquid)
Bottle brushes (baby section)
brushes for pots and pans or any type of plastic scubing brush.
Soft mat for bathtub.
Gloves if you don't want to get your hands dirty.

Some laundry Detergent like TIDE (preferably the dry, not liquid). Get something soft to put on the botom of your bath tub and fill the tub with hot water with detergent. Scrub it with bottle brushes. Get some platics brushes that are used for scubing pots and pans. Do Not use metal brushes. Don't use any chemicals like carb cleaner or brake clean unless you're doing this out side.


other than removing the vtec solenoid what else should i do?

thank you

nada? no opinions?

 

bring it to a machine shop or places that does work on heads will clean it up perfectly for like 50 bucks

 

well with some engine degreaser i was able to clean it up really well except for the carbon in the exhaust ports. so after i do the valve lapping im gonna have it acid dipped.

should be lookin purty after that

 

i would bring it to one of those out door DIY car washes with the high pressure water.

 

Go to a machine shop and have it baked and cleaned.

 

good thinkin. my dad also suggested this. unfortunatly they closed the only close one. now its 20 mins to the next closest one

 

i honestly dont think he meant laundry detirgent. there are special detirgents for these applications. if i were you id disassemble everything and steam clean the head itself. as for the other stuff, well dont steam clean that stuffunless you wanna screw things up and lose stuff. find the apropriate detirgent and go from there.

 

here is how the head is sitting as off now. after a couple applications of engine brite. im ready to do the valve lapping now, but the stick i bought for it does not suck at all. it wont suction to anything!! its junk so i have to find a better one.

 

I've used Castrol Super Clean on a rotor and housing before... it melts the carbon right off.

It seems like the engine brite did a pretty good job.
