Where lies the line between varnish and sludge?

Depending on how you look at it, it's either a little bit of sludge or a ton of varnish. smile

The unstoppable sludge versus the immovable varnish. Or vice versa

My perspective, as well.

VML is all the flush she'll get, along with a new HG, timing belt, and ignition tune-up. If your call has a slow coolant leak... just fix it.

15-year-old Honda, about 13,500 miles a year...doing pretty well I'd say. Whatever oil or oils were used, they did not cause engine failure...Honda engineering still doing well.


turn in your old jackets, shirts and other clothes to a Salvation Army or any homeless shelter this year...

Wish my pics to my 01 Civic at 168k miles in this thread still active (thanks PB) as similar valvetrain design to topic.

I'll say though I've seen worse (not much) IMO topic engine is sludged. As comparison mine looked very similar to the pic below from another Civic in a youtube about how to adjust valves.

That' a clean engine.

Does the crankshaft turn? smile

Looks like a good candidate for LCD's LC20. Pour it all over the head, let it soak overnight, scrub, re-soak, scrub.

Also, do a piston soak with this stuff using about 4 oz. per cylinder.

I brought a 454 back to life this way after a friend's daughter let the oil level get too low in his Burb. shocked2

The only thing we had to replace was the valve stem seals. We let the hydraulic lifters soak for about three days and they worked fine.

Scars remind us of where we have been, but do not have to dictate where we are going.

Any worse and I'd deem it out-and-out sludge. But, true, not close to the fail point yet - just not doing the car or the owner's wallet any favors. It'll have to run better after I get done with it, based on the deposits on these pistons. VTEC gasket screen is gummed up pretty good, too. Regular gas, most likely dino oil, lots of city driving - I wouldn't expect much better.

If it turns, and no one hears it.. Does it make a sound?
