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!
