Slimy build up in water ways

[Cb7-Ba4]

Hey everyone I bought me a cb7 that had a broken timing belt.I got all Honda parts to part it back together.Had the head redone at the machine shop.

I pulled the old water pump off today and there this brownish slimy shit on the pump fins.I also noticed there is this same build up stuff around the cylinder walls,well around the outside of them in the block,I'm sure you guys know what I am talking about.

What is this stuff, is this normal build up or something? How should I go about cleaning this stuff out ?

[F20A CB7]

its normal build up and from the the water pump thats all old res due from the coolant, change that dont clean that, and as far as the outside of the block its jus old build of grease dirt etc. Engine degresser is the best, take it to the car wash and pressure wash it down have car runnin tho cover up the dist.

Ohh ok. I didn't mean the outside of the block.I mean in the block..on the outside of each cylinder wall there is a passage for coolant,that same build up that was on the water pump is in the passage way that goes around each cylinder.I have never seen this kind of build up before.

I don't care about the grease build up on the outside of the block.

If I can get the pics off the camera to the pc I will post them.But still need some ideas on how to clean that stuff out, or should I not bother with it ?

[F20A CB7]

o o ok ya that happen to me to my motor had alot of miles over 220K and it blew.

i really dunno but im sure some of the guys here would know, but i would do it get a coolant cleaner and jus flush out the coolant.. anti freeze change.

and jus run water through the motor and clean it that way and ull c some of it actually break loose

if u gonna do this take out the thermostat and jus leave the rubber gasket on so no water will leak when u cleanin it

[Cb7-Ba4]

Well what do you guys think this stuff is ? It could be stop leak stuff, cause I remember him saying he put some in at some point.

Just trying to figure out if I should clean this out while the head is still off,or just flush it out after I get it running?

F20A CB7: You need to start using normal fonts and colors.


I have seen buildup like this, only in GM's and vehicles that use either DEXCOOL, or ACDelco coolant. So someone tried using american junk on your not so american car, and well. You get the picture. In other words, someone was using an oil based coolant in the car. TTFN.

ill use wat i like

If your trying to post useful information, its best to do so in a presentable manner, not an annoying one.

[Cb7-Ba4]

Aww come on people.I know someones else has something to add to this to help me out.

I could have put it all back together by now...

[areem57]

Get as much as you can while everythings apart then once its all back together flush it, is it like a sludge? Does it seem like a flush would knock it out?

[Cb7-Ba4]

Its not really a sludge.Its more of a film of brown shit.Kinda like when gravy gets that film/coat over it after sitting for a while.Ya know?

But at the bottom of those passages around the cylinder where the slim shit is.There seems to be crumbs of harder like shit.I'm really thinking this was some sort of radiator stop leak stuff..but not sure.

I'll clean what I can out, and give it a good flush after shes running.Is there a plug on the block where I can flush the block while the head is off? I know on my lude there is a big bolt behind the exhaust manifold for that,didn't see one on the accord tho.

[NAiL05]

Prob sludge that has developed over the years in your radiator. Thats where it usually catches. Just flush out the system and rebleed and crap youll be fine.

[Cb7-Ba4]

Ok cool I just wanted to make sure.

Is there a way to tell if the timing belt tensioner's are bad or not ?

I also noticed that all pistons are half way up,all at the same position.Should I turn the crank or put those any certain way before installing the head?

Translated so that it can be seen..

Simple Green and a toothbrush does wonders also. That is what I use on my engine bay..

Also technically your ARE NOT supposed to use HIGH pressure when washing your motor... You should ALWAYS use low pressure when working around the motor. High pressure can overtime damage gaskets and eventually wear them down from the outside to the inside thus letting water in and oil out.. Just my two cents.. Later
