how do you clean the valve cover (inside)?

[spyghost]

hi,

how do you clean the inside of the valve cover? i believe there are baffles inside that are unreachable to a small brush.

what "cleaner" do you use?

kerosene?
gasoline?
diesel?
degreaser?

pano sya? kuskos? or soak?

[bambino]

pwede na jan ang kerosene and rinse it with water .

then sandblast . it will look like new

i used water based degreaser. soaked it then kuskos ng konti, banlawan mabuti then patuyuin... and then okay na looks nice and very neat

Kerosene then water rinse is ok.

Sandblast is not recommended as the fine particles may imbed on soft aluminum. Particles may also adhere to oily surfaces and cause possible engine damage. Sand and/or glass beads are abrasive.....

nakalimutan ko na sabihin na banlawan ulit pagkatapos i sandblast

that's what we do here in canada , we sandablast the heads , valve covers , and we haven't had a single problem 16 years now .

sand and glass beads won't damage the aluminum , or steel covers .

i use that everyday in my shop.

spy,
if the valve cover is painted, it is more practical to use paint thinner or turpentine or mineral spirits that yo can buy at ace hardware. this requires chemical cleaning as liquids gets into tiny crevices unreachable by brush. if the crud is more like hardened gum and varnish, you might want to try oven cleaner on the crusted parts and let it soak for about half an hour and rinse with tap water. i used to use simple green or kleenol to soak parts with. the only problem with these latter two is that it melts the paint on the valve cover and it's not gonna look pretty as before, just bare aluminum or steel. if the valve cover is of steel, sometimes the finish is black japan (similar to porcelain) and is resistant to these two chemicals. similar to this if the simple green or kleenol is not available is the aluminum hydroxide detergent used to clean airconditioner evaporators and condensers. it melts grime away and push them out of the cooling fins which of course is similar to the tiny crevices of yor valve cover. just be earth friendly, dispose of waste responsibly.

spy,
you can find this at airconditioning supplies. this what they use to spray the fins to expel dirt and grime. or you cna use oven cleaner, they have the very same composition. you make this concoction work its way into the tight gaps and rinse it off using water.

as with other engine internal surfaces and drilled orifices that get clogged up from overcooled engines or prolonged engine oil change intervals, i highly recommend adding engine detergent to the engine oil to dissolve sludge buildup. diesel engines already use this as regular engine oil: HD engine oil which stand for high detergency and not heavy duty as what most people have a misconception with. the detergent in the motor oil will not be sufficient to remove excessive build up when the service interval has been overextended and abused. or for the next few oil changes, it does not harm the engine if you use high detergency oil. you will notice the used oil to be dirty because it is doing one of the functions of the motor oil: to clean the engine internal components
