February 25th, 2014 12:03 AM #1Guys I need some advise sa mga may alam sa ganitong engine.
QG16DE is in my nissan exalta. I encounter hard starting problems then a mechanic inspected my spark plugs and found na basa lahat ng oil and yun daw ang cause bakit mahirap i start. Sabi nung mechanic i should replace the valve cover to fix the leak dahil kasama daw sa valve cover yung mga seals.
Is the mechanic right, or is there any other oil seals / spark plug seal that can cause a leak? Mahirap po kasi maghanap ng valve cover and tingin ko sa casa lang ata meron na brand new. Meron na po ba naka encounter ng ganito sa inyo?

Sir, mostlikely overhaul na iyan, pagsinwerte kaya pa ng top overhaul yan.
kasi kung valve cover lang hindi dapat basa ang sparkplugs mo kasi sa ibabaw iyun, oil seal (yan ata term) naman sa ibabaw tatapon langis mo - nangyari na sa akin yan although ung sentra ko eh 1.3L carb type lang.
try mo paestimate sa Fritzie Trading along molino blvd. (medyo mataas sila magpresyo) or sa Ros Autoworks (mura ito, pero havent tried them, pero madami ako nakikita na nagrerestore sila ng old school na auto. along molino near soldiers hills 4.

Have a compression test done first to determine what exactly could also be the problem (piston rings, seals, etc).

I correct mo muna yung pag babasa ng sparkplug ng oil, usually yung sparkplug oil seal na nasa valve cover ang culprit. some engines ay kasama na sa valve cover ang mga sparkplug oil seal meron din hiwalay. madali lang naman tanggalin yan.

March 7th, 2014 10:47 AM #7which part of the sparking plug is wet with oil?
if it is the porcelain end, then it's probably due to oil dripping from a defective valve cover oil seal above.. this can be fixed by replacing the gasket with a new (never used!) seal.
but if the business end (sparking end) is oil-fouled, then it's probably worn oil scraper ("piston ring"), valve seal, head gasket, or (gulp!) cracked engine block.. ka-ching!!!

March 8th, 2014 12:58 AM #8Tingin ko dun lang nag leak sa may spark plug tube. Hindi ko naman napapansin na nag babawas ng oil.
Ang problem kasi is mahirap sya i start kapag mainit na yung makina. Kapag sa umaga or matagal di nagamit isang start lang okay na. Kapag tinakbo na sya tapos nasa operating temp na then pinatay ang makina ayun ang hirap na i start. Kaya ginagawa ko tinatapakan ko gas habang i start yung makina.
sabi ng mekaniko basa daw kasi yung spark plug kaya mahirap sstart. But im not yet convinced kung yun ba talaga yung reason. kasi nasa spark plug tube lang yung may oil leak.

^^^ sorry sir TS ganyan na ganyan nangyari sa akin oil seal muna ng sparkplug bumigay. Kaya ung langis nasa ibabaw ng sparkplug. Pero nun binuksan sangkaterbang sludge na nasa cylinder kaya medyo may blowby na din ung sentra ko dati, in fact di nababasa ng oil ung sparkplug ko. Pero ayun pagkalinis nakita depekto at full overhaul na nangyari.
