oil in spark plug cyilinder

[92accordexpower]

Though his lower seals are the most likely to be failing right now, which definitely takes more than 10 minutes to do; you have to remove the whole rocker assembly.

if the upper tube seals are bad, it will get oil on the spark plugs 100% of the time, and they go bad quite frequently compared to lowers. it's a good place to start either way.

DIY for lower tube seals

i changed the lower oil tube seals because of the same situation you are having and my car ran much better than oil coated spark plugs. There is a weak spark emitted when the electrode is covered with oil.

[topcop182]

could it be the piston rings?

[ExplodingCake]

If it's piston rings , you'll have smoke.

[JunyAccord]

yah, you would be "burning oil" in the piston chamber due to the rings.

oil outside the engine...bad seals

oil inside the combustion chamber...bad rings

You need to take off your valve cover and replace the seals at the top of the spark plug tubes.

There are ALSO orings at the BOTTOM of the spark plug tubes but you will have to get into the head a little more to get to those.



that is what you need
FELPRO part#VS50365R

The bottom ones you see are the top seals, next are the orings, then the grommets for the 10mm VC nuts

when taking off those lil' 10mm nuts that hold the VC on, make sure your INCH POUND torque wrench is accurate...those seem to be WAY easy to snap.

So are the o-rings that come with the kit for the bottom of the tube seals, or are they to be used with the top?

The O-rings on the bottom are most likely what's leaking. The top seals do go bad, but the bottom ones experience a lot more heat and probably fail more often I would assume.

To fix this problem you'd have to remove your VC, then remove the rocker-arm assembly, making sure cyl 1 is set at TDC. There's also a sequence of removing those screws you have to follow in order not to warp anything. Took me about 3 hrs my first time ever doing it on my F22. So it takes a bit of time to do it correctly. I think I also adjusted my valves after I reinstalled the rocker arm assembly b/c I was paranoid I screwed something up, but that's not necessarily needed I found out later on. Oh and btw, if the rocker arm O-rings are all you need, don't waste your money on buying an entire Felpro kit. These are only like 3-4 bucks a pop at Honda and they're OEM quality rubber, they'll last.

I dug these pics up from when I did mine, so you'll get a better idea of what you're in for:

Here's some pics I took when I did the replacement of the Rocker-arm O-rings:






















old petrified O-rings that didn't seal for shit







new O-rings, much softer rubber

Thanks man. Pictures speak 1000 words and you've cleared up just about everything I was wondering about on this replacement.

[Jon]

What's with the manual... you should know this stuff by heart.

But yeah the pics definitely help. I've tried to explain/show people where the lower spark plug tube O rings to people without pics which is kinda hard.

top that sits and acts as "grommet seals" under the vc on top of this stated 'tube' lol. There's also the vc gasket itself there hangin out too

[dbales]

Another quick question about this, does the rocker arm assembly come out as a whole unit and go back on as a whole unit without any adjusting to do?

[CB7_213]

yes its a whole unit, u just need to do the valve lash adjustment.

I just want to thank all you guys for the info shared, I'm about to get this started myself, I'll let you guys know what happens.
