Oil in plugs

[pomelo]

Had my valve cover gasket replaced last week (sa Total Baguio). Since nandun na din, had my engine tuned up (palit spark plugs) and changed oil. This afternoon, when I checked my plugs, there was oil sa #1 & #2 plugs (na wala naman before pinapalitan yung cover gasket) and when I took them off, medyo maluwag, so it seems that the service mechanic missed tightening the plugs. So ginawa ko, I took off the plugs and wiped them with a dry cloth. Pati yung kung saan nilalagay plugs, wiped it also. Ano kaya problema? Kase yung nilagay na sealant nung mechanic parang masyadong manipis (as in hindi man lang naubos kalahati ng isang tube of the sealant). Is it the sealant kaya nagkaroon ng oil ang plugs? What preventive things should I do?

Thanks in advance!

sir baka blow-by yan. observe mo muna. kung nababawasan nang langis, have it check by your trusted mechanic...

[orly_andico]

oil on plugs is 95% of the time bad valve cover gasket.

*ian_rex, tinatakot mo naman siya!! blowby is possible pero yun na yung pinaka-scary scenario.

i'm willing to bet mali pagkalagay nung valve cover gasket, either kulang yung silicone, or naipit yung rubber gasket when it was being put back.

maybe the plugs are not torqued enough. check if it's 1/4 turn after contact or if it conforms to your vehicle's manual.

wat car sir?
if some of the plugs are wet with oil:
if the plugs are in between camshafts and deep inside the cylinder head (civic, corolla GLi, lancer, etc.), it is the spark plug oil seals.
if it is at the side (corolla xe, carb types, etc.), check the engine compression

if all plugs are wet, check engine compression and check oil level. lose compression and overfill can cause the plugs to get wet with oil...

Btw, pag bago yung gasket wag mo lagyan ng sealant except sa specific corners lang ng gasket. The gasket is made to seal itself kung malinis yung surfaces na nilalagyan nya.

faulty tightening of the VC gasket will not lead to oil in the plugs. that's caused by either sparkplug oil seals or cylinder o-rings that are worn. or bad valveseals.

boss,ibalik mo na lang sa total at sila ang mag-check.sigyro naman honest sila dahil warranty nila yan

[sirkosero]

oil ba o gas ang nasa plug? how'd u know it was oil?

at first thought, pakiramdam ko piston ring e.

oil on plugs is 95% of the time bad valve cover gasket.

sir, i guess, nasa remaining 5% ako. just replaced the valve cover gasket of my LXi, even before replacement i haven't had problems like these (oil in spark plugs.

which part of the plugs has oil on it? is the oil on the threads, or on the tips? are you losing engine oil?

[rayban7g]

speedyfix is right,.. it's not the gasket cover to cause that leaked oil on the plugs,. rather it's the plug oil seal (o-ring), or if so, valve seals na yan!.. ganyan sa liteace namen kasi!

[finchy18]

dont forget the white smoke.

[speedyfix]

if it's in the tip then it's the seals under the rocker arms at fault. looks like this... 0 0 8 0. 4 pcs.

[umzzzzz]

what a coincidence...i'm having the same problem now!


*finchy, blow by na ba kung may white smoke sa exhaust? (in my case, wala pa naman)


i discovered there was oil in my plug #3 (3rd in firing order sequence) by inspection (tinanggal ko yung high tension wire from the top, then i peeped; kumuha ako ng stick na may bulak sa dulo to confirm kung lagis nga, then i dipped it under, and i found out that it is really oil. fresh pa ang langis; hindi pa maitim.) hula ko ay o-ring...my ride has a PH12 engine... any suggestions guys?

[finchy18]

umzzz.. hindi rin masabing blow by na talaga pag white smoke coming out from the exaust pipe very possible cause is worn out valve seals at dapat ng palitan. malaman mo nman yung condition ng engine kasi mag iba yung sound niya at pwersa. kpag 3rd lng yung may langis mukhang one of the valve seals are worn out or oil leak kaya nabasa yun spark.

sa akin worn out na talaga valve seals ko kasi may oil sa ignition tip ng spark plugs at mausok na (white) more rev more white smoke and im sure hindi lose compression kasi yung hatak hindi nag iba at yung tunog ng engine maganda parin.

yung trusted friend ko na mechanic sinabihan ako na bumili ng overhauling gasket pra sa top overhaul.

sayo mukhang a little replacement lng..

ummz tanong lng ano auto mo?

[umzzzzz]

ummz tanong lng ano auto mo?

EG hatch po. 95 model. engine is all stock.
magkakano naman ang gagastusin if ever i have to replace valve seals, o-rings at kung bibili ako gasket seal? bago pa kasi yung gasket ng top cover ko. mahal ba ang pagpapagawa neto?

[pomelo]

Thanks for the replies guys.

Binalik ko nga sa Total last saturday and the leak was caused by worn out oil seal's/o-ring's sa spark plug socket. All 4 were brittle already so bumili ako ng 4 oil seal's/o-ring's at 200 pesos each. Since then, wala pa naman oil leaks. Car is Gen1 CRV pala.

Thanks again!

[umzzzzz]

cool. congrats sir/madam pomelo!!! saan mo pinaayos yun? sa total lang din? magkano lahat lahat inabot pati labor??

[pomelo]

cool. congrats sir/madam pomelo!!! saan mo pinaayos yun? sa total lang din? magkano lahat lahat inabot pati labor??

Yup sa Total din. Oil seal cost 200 pesos each or 800 for the 4. Tapos sa Labor 200. So 1000 all in.
