What the hell is this?

[HardInThePaint]

I just bought this cheap ass CB and removed my valve cover to replace the gasket and discovered all this bullshit gunk in my shit. What the hell is that? And how in hell do I get it outta there? I've already drained to oil and whatnot. Can I seafoam this shit? Please help a brotha out.

i can't really make out what that junk is!! Could u post a bigger picture?? It doesnt look like rust, but it might be oxidation of some kind..

[BabyD91904]

jus looks like sludge build up to me if it was me i would take tha head off and clean it out real good b4 puttin it back on.

[Nerocb7]

metal shavings??? or maybe the last owner added some oil leak repair sh** idk was the car running fine before you saw this???

Yeah that looks like what it is to me too, some sort of sludge shit. I've never removed a head, how long does that take? And what do u use to clean it out?

Yeah the car runs. I drove it home.

maybe never has an oil change you better seafoam that engine

[Puertorican CB7]

yea seafoaming it is a good idea... just hope it does not start leaking oil afterwards tho...
i had that happen to me once on an old hyundai

Can I seafoam this shit?

Well i dunno if youve used seafoam before , but i heard that sometimes it can disolve the seals in youre block ... plus it looks like a four alarm fires worth of smoke is shooting out of your muffler i would def pull the head and clean it all out real good if youre not to sure of what it is

Seafoam is meant to clean out your intake manifold mostly, it wont have any effect on internal engine areas like under the valve cover (although seafoam may remove a small amount of deposits from within the actual combustion chamber). All that "junk" is just engine oil sludge which normally accumulates over time (although can accumulate alot quicker, if the owner gets lazy on their oil changes). Using really cheap oils (which contain less additives) and/or conventional oil also contributes to sludge build up quicker (synthetic oil is made up of uniform hydrocarbon chains, and generally does not contain as many "bad" chains of hydrocarbons which form sludge easier).

The only real effective way to remove all that sludge would be to remove the cylinder head and have it hot-tanked (or acid washed, whatever you like to call it). Or if your on a budget, you can remove the cylinder head and scrape it out and use brake-clean or carb-clean to wash away the remaining sludge. I wouldnt reccomend trying to scrape away the sludge with the cylinder head still on the engine, because the little chunks you cant pick out will eventually get circulated around the oiling system and can clog small passage ways.

They also sell engine oil "flush" kits, that you add to your engine oil, which supposably loosens up sludge and deposits, and removes them. Only problem is all that sludge has to go somewhere, and will most likely clog your oil filter or get stuck on the way. I wouldnt reccomend any "mechanic in a bottle" type fixes. Your best bet is to remove the head and go from there, but if its not causing any problems (yet) it may not be worth your time.

Yeah I will put oil back in it and pour seafoam in the crankcase and then do an oil change. Hopefully it'll get that sludge up outta there.

I hope your being sarcastic because that's not a good idea. I believe seafoam does state on the back of the can that you can add it to engine oil, but whatever sludge is removed is not going to magically dissapear, its going to end up in your oil filter or anywhere in the oiling system before the oil filter, therefore I would not reccomend it.

By the looks of the picture your engine seems to have alot of miles on it, I wouldnt worry about the sludge for now, it may cause more harm trying to get rid of it, than to just let it be at this point. Your best bet at this point would just be to focus on doing regular oil changes, and wait for a future engine rebuild to get rid of that sludge since there is so much there already.

time f0r a rebuild.als0 if ur just g0nna d0 the head.take 0ff the r0cker assembally and the cam and just use degresser and a wire brush.

Looks like oil sludge from not changing the oil in awhile.

[alb_accord]

do an oil change. put 3 2/3 oil and the rest kerosene. run the car for a few min. change the oil, drive for 500 miles. then change the oil again.... that should clean it up really good. then check if it is metal shavings in there or if it just sludge

Truthfully, If I were you, I'd drop the oil pan and inspect the crank case. Its possible the bottom end might look the same way, and possibly have metal.
