oil on my sparkplugs

[jeffishot]

Was cleaning my sparkplugs the other day and i noticed that there were traces of engine oil on it. those this mean big trouble for my car? BTW, my car is a '95 corolla.

Is the oil black and thick?? This may not be motor oil.

I think the car is running rich. Malakas sa gas siguro yung car mo ngayon and parang palyado sa umaga.

medyo black ang oil and quite thick. napapansin ko na malakas siya sumipsip ng oil. ilang beses na akong nag refill ng oil. i usually refill two liters every month. medyo malakas siya sa gas considering XL lang siya. 1 liter is to 7 or 8 KM ang consumption. medyo palayado din siya. ano kaya problema nito and how can we fix it. i hope its not something big like an overhaul job or something.

looks like top overhaul na kailangan... replace valve seal, head gasket etc. u would shed about less than 10k depending on labor and what time of parts to use.

[jeffishot]

top overhaul na talaga kaya to bro?

Same case as my previous car (Corolla xl 93). Your engine requires top overhaul. You have to buy at a nearest toyota dealer a Valve Seal Kit which will cost you P2962 (price last year at Toyota Cubao). Some kit are available at some auto supply which are less expensive but it won't guarantee you how long it will going to last. Choice is yours. I suggest you buy genuine toyota parts. I have the valve seal replaced at a good/trusted shop which cost me P3k for the labor. Other items would be 4 liters of motor oil and oil filter if so requires. Be sure to ask the mechanic to clean also the cooling jackets before re-assembly.They just fixed mine in a period of 6 hours. That's it.

Refilling 2 liters of oil every month is not normal. Definitely gastos yan pero the sooner the better baka magdamay pa.

[sirkosero]

dagdag ko lang, when buying parts, go to genuine parts dealers. gant sa pasay. toyorama sa banawe. when possible, magdala ka ng mekaniko na marunong sa piyeza para malaman alin ang peke sa hindi. a few months ago, nagpatopoverhaul kami. 35 ang NOK daw na valve seal. pero may isa pang NOK na valve seal 120 pesos naman... buti na lang yung gumawa eh kamaganak ko na taga toyota kaya alam alin ang peke.

If you are losing motor oil then correct ang diagnosis ng mga nag post sa taas.

Some cars, also have black and thick oil on their spark plugs. Mali ang kasi ang fuel-air mixture. Either Rich or lean ang mixture. The effect of a rich mixture is an oily sparkplug. It also causes high fuel consumption.

Kung carburator ang xl corolla then maayos yung fuel-air mix with a proper tune-up from a reputable car shop. Have it checked to be sure before a top overhaul. Alam mo naman ang mga talyer minsan, pag pangit ang takbo ng engine, overhaul kaagad.

paano malaman kung tama ang fuel-air mixture bro? gusto ko kasing yung tamang tama lng or normal consumption nya.. paano ba or san eh adjust mga to?

[jeffishot]

i just had a light tune up sa shell gas station pero wala pa rin. ganon pa rin ang takbo.

Light tune up won't solve the problem. It wil just add up to your expenses which you should be spending on the right solution. As per my post above, I forgot to tell you that in my case I just add up 1 liter each month of oil. What's more with two liters? That's more than unusual. Nevertheless, if you want to stick with your car, go for the top overhaul. Otherwise, have it detailed for resale. Good luck.

jeffishot, the best piece of advise i can give you is to bring the car to a reputable shop (like speedyfix) for you to know what's really wrong with it.

[jeffishot]

salamat mga bro for the comments. i really appreciate it
