So this morning the sun came out, i decided to take a look under my hood, check for oil, power steering, antifreeze, etc. Then i pop my spark plug and WTF!!! what do i find...oil in the spark plug chamber. This never happen b4, i change the stock to the Bosch platinum 4 3yrs ago when i got the car and now this happen!? I'm guessin i didnt tighten the spark plug enough cus when i losen it, i didnt use that much force. That mite be the problem or is there a leak sum where, what do u guys think any ideas or help, thanks. I'm in the process or takin all my spark plug out at the moment.

looks like oil leaks from spark plug tube seal.
valve cover gasket is leaking too? I guess it's time to
replace valve cover gaskets. and why bosch?

What car? A CLS don't use those. Clean up & install to correct spec'd plugs.

mr2fast2thao

thanx. where can i find the NGKs, at my local auto store or do i have to order em? & u sure my valve gasket is also leaking, i look around and no leaks?

The valve cover gasket is most likely not leaking too but,if one's seal is leaking the others are sure to follow if not replaced.

mr2fast2thao

ok thanx, ill replace the valve cover gasket just to make sure

Might have been a spill from a sloppy oil change but more likely the seal is shot. Clean it up and see if you get the oil build up again.

If the Bosch plugs have been working ok for this long I'd leave them alone.

I would change the plugs to NGK and get a valve cover gasket kit with the grommets. Should be about $30 and should have tube seals, top grommets, and valve cover gaskets. When you change it, clean out the intake manifold and thorttle body.

I don't get why all these people use differen't brand plugs for Honda/Acura.....NGK#6994/IZFR6K-11 is what your suppose to use. Anything else, your on your own.

Honda/Acura: NGK
Toyota: NGK or Denso
VW: NGK from what my VW tech tells me now
Ford: Motorcraft
Chevy: AC Delco

NGK is really the mostly used brand for imports and even some Euro's.

hey sac dude,

I wanna say tube seals are going bad. Also make the change to NGK, those are the right plugs for our cars. How many miles on the engine? 105k service done on it yet?

2 mistakes.

you havent changed your plugs in 3 years

and you used bosch plugs

its just oil blowby

mr2fast2thao

back when i got my car i didnt know about NGK spark plugs, all i heard and see is Bosch, even when i walk into pep boys or autozone i see em. well i just finish puttin the new gasket in and what i see is the one that has oil, has a little crack on the seal, thats y it was leakin. sry for got to take pix. imma use the bosch for now cus the rear spark plug is a bitch takin them in and out with so little space, so ill grab sum NGK this weekend and slap em on.

mr2fast2thao

the motor has 92K. if i take it to the dealership, how much is it for the service, anyone done it b4? cus if is to much them i can just do it myself & save sum $$$ for beer

Allout

I've never changd the tube seals. What's involved?

Nicks01CL-S

the deal charges like 150ish i think i asked before i did mine. i was like i think i can handle it myself..... but the back isnt too bad. i got the NGKs love them they last and are recommended. i do believe that in the owners manual and maybe under the hood(not 100% sure) it has the NGK number. but ya the deal will charge an arm and a leg for a simple job. just tough it out

Denso ftw!

i havent done it personally but I got my mech to change them as part of the 105k. I know you have to take off the intake mani and the valve covers. but by that time, might as well do a valve adjustment, plugs, valve cover seals and thermoblock spacers if not replacing the gaskets.


naw, NGK Lazer Iridiums. Now thats the good stuff.

feel free to ask your local acura dealer how much they are.

mr2fast2thao

what types (NGK) do u guys have on? should I just grab the top or best NGK spark plug?

YeuEmMaiMai

put new tube seals in. problem solved

mr2fast2thao

yea its the spark plug tube seal that has a crack, got all 6 of the tube seal replace and brand new valve cover gasket dont know y it crap out only at 92k is it common at that mileage?

best ones are the NGK Lazer iridiums. They are pretty pricey though but thats OEM stuff and will lask another 105k.

my tubes were still good but I never touched the plugs before.
