Engine leak on my 2005 Altis 1.6E A/T

[KinKyHOOTER]

Hi guys! I have been monitoring an engine leak for around 6months now; its at back of the engine.

• The oil goes low to the middle of the F and L dots after 1month or so so thats when I top-up.
• No smoke on the tail pipe
• Spark plug burn is ok
• Coolant level is fine
• No oil in the radiator
• Engine shifting is ok
• NEVER had an overheat issue
• Engine and A/C fans work great
• Aircon is well maintained

I had my oil change last Monday, Oct 11. When the car was raised the the mechanic at Shell SM Sucat checked it and said it could be either the:

• Cylinder head gasket = Php 622 (Price as per TM Pasong Tamo)
• Valve cover gasket = Php 1,565 (Price as per TM Pasong Tamo)

My car's mileage reads 78,000kms only and change oil is every 5kms with Shell Helix Plus 10w-40 Semi-synthetic (BLUE). Got the car 2nd hand from my aunt who had the cars regular PMS at Toyota Makati.

I went to Toyota Pasong Tamo earlier and asked also the possible reasons for the oil leak. They also advised the same as above but the Service Advisor said that the CYLINDER HEAD GASKET angle might be slim at 78,000kms mileage and if the care never had an overheat issue since.

He said it is possible that its the VALVE COVER GASKET or an OIL SEAL...(I forgot what oil seal it was that he mentioned). Anyhow he said to have it checked just to make sure. Which I plan to do so when the budget is ready.

Since I still dont have the budget for this possible repair, my question is.......What harm will it bring the engine? Any tips? Advice?

I plan to have this fixed sometime December in time for the 80k PMS, when it reaches 82k kms.

Prior to this repair concern, I already planned to change oil every 2months or 3k kms mileage which ever comes first using Shell Helix Plus 10w-40 Semi-synthetic (BLUE).

Thanks!

rear crankshaft oil seal ang malamang na sira.. possible din may leaking hose... ibaba ang buong transmission nyan for oil seal change

ganyan din ang ZZ namin. then the engine died due to sludge.

I would recommend na ipa-open mo ang engine cover para makilatis ng mabuti. If there is sludge, then it has to be removed. if none, then kampante ka.

got the same problem, but no leaks to be found, neither any oil consumption is detected. but mas mabagal lang magbawas ng oil yung sa akin, 1/4 lang ang nababawas kada 1 1/2 - 2 months. my engine is at 99.1k km.

will try to switch to a thicker 10w40 or 15w-40 oil on my next pms, then replace my VC gasket since i remedied it before with a silicon sealant.

no sludge yet, i assume.kakabukas ko lang ng top cover last few months.

Yes I think the TM Pasong Tamo mentioned it could be the crankshaft oil seal. I dont think it could be a hose as the leak is directly coming from the metal part of the engine. The hoses looked ok.

Sana oil seal nga lang. Will have it checked soon.

What harm will this do?

Hehehe. Yeah I was following your 9th Gen Altis story. Wow hindi ako makatulog noon pre. Hehehe

Yes will have the engine opened by December for the 80k PMS. I dont think its a sludging issue. Wag naman.

Thanks sa advise

after 10,000 km mula ng na overhaul ang makina ng ZZ. ipa open ko sa nekaniko para masilip. naka 5,000+ km pa lang.

nagtataka nga ako noon. hindi mausok, walng oil sa coolant, walang tagas pero nagbabawas ng oil. madami rin akong naidadagdag na oil bago ng susunod na oil change. now kahit na after 4,000 km, hindi nagbabawas.

after 1,000 km mula ng overhaul, change oil ako from mineral to semi synthetic. then change oil ulit after 4,000 km. next ay every 5,000 km using semi synthetic.

crankshaft oil seal - kung nakikita mong namamawis or may tagas ng oil sa mismong ilalim ng transmission.

malaki po ang crankshaft oil seal compared sa mga oil seals sa harap ng engine (yung pinapalitan kasama sa timing belt package). what I mean is, kung M/T kasi ang auto niyo, then isinasabay na rin ang pagpalit ng clutch assembly diyan para isang babaan nalang ng tranny, but since A/T kayo, all you need is to change your oil seal.

I see. Baka normal oil consumption lang ng engine at that mileage noh?

I thought you were using RP 10w-40 na?

Yup I saw your engine photo when it was opened. I hope mine is as clean also.

not normal for me. i think its that cheap 0w-40 ZIC FS oil i used that caused it. at 90k - 95k km.

before that, di naman nagbabawas ng oil.

now im using RP 10w30 from 95k km - present.

you can open the top cover DIY style anyways. madali lang naman.

and nagtataka din ako, wala naman leak sa crankshaft (kakababa lang ng tranny before, maybe at my 80k - 90k km, limut ko na). totally no signs of leaks.
