oil leak at valve cover

[astina]

mga bro just need help!ang ride ko is mazda astina and engine is just typical 323 1.6. Kasi po parang every six months or wala pa nga eh nagpapawis ng langis and makina ko sa may valve cover. eh ayaw ko pa naman na madumi or malangis ang engine bay ko lalo na pag may kinakalikot ako. He he he!What po advise nyo mag palit na naman ako ng gasket (eh wala naman ako makita original) and what po kaya maganda brand ng sealant ang maganda for engine? Thanx po!Any idea or suggestion would be highly appreciated

Original or not will do. Also apply high temp. silicone sealant to the corners where the cam bearing caps, cranks angle sensor caps meet the cylinder head if you replaced the valve gasket.

Clean your PCV system. Inside the valve cover there is usually a metallic filter,
pag barado ito, the increased pressure in the crankcase can leak through your valve cover gasket within a short time after you replaced it.

Dati akala ko, low engine job na ko, but when my PCV system was cleaned nawala yung mga leaks at na-restore yung power ng kotse ko.

Hit the jackpot. True, most common problem of leaking gasket are clogged vacuum hose, PVC, oropice.

Mga bro thanks sa mga suggestion nyo! About PVC ok naman sila kasi the last time na nagpalinis ako ng carb. lininis din nila eto. yung nasa may hydrovac ba to? and lininis din nila yung sa may valve na naka-connect sa carb ko. binugahan lang nila ito ng hangin. Tama ba yun?Thanks alot bro's for your help and suggestions!

Same question: for EFI engines

How can you check na clogged or madumi ang PVC?? may leak din ang gasket ko and napancn ko di nman sira ung gasket ko na orig, pero may leak pa rin, pero nag palit ako ng raplacement, may leak pa rin... akala ko dahil lng sa pagOver Rev ko ng kotse...

OT: panu pag sa may distributor ang may Leak?? O-Rings ba ang sagot?

checking the PCV valve (this is for toyota from www.autozone.com)

Inspect the PCV system hoses and connections at each tune-up and replace any deteriorated hoses. Check the PCV valve at every tune-up and replace it at 30,000 mile (48,000 km) intervals.

The PCV valve is easily checked with the engine running at normal idle speed (warmed up).
1. Remove the PCV valve from the valve cover or intake manifold, but leave it connected to its hose.
2. Start the engine.
3. Place your thumb over the end of the valve to check for vacuum. If there is no vacuum, check for plugged hoses or ports. If these are open, the valve is faulty.
4. With the engine OFF, remove the valve completely. Shake it end-to-end, listening for the rattle of the needle inside the valve. If no rattle is heard, the needle is jammed (probably due to oil sludge) and the valve should be replaced.

yung sa leak sa distributor dapat alamin mo kung sa labas o sa loob galing yung leaking oil.

pag sa labas, yung o-ring and problema.

pag sa loob, oil seal ang kailangan palitan.

Kapag nag leak na ang gasket may tagas na. The only to correct the leak is to change the gasket.

change the valve cover gasket.
Go OEM

naninigas ang Replacement. hindi naman magkalayo ang presyo nyan

*V6dreamer,
what do you mean by change the gasket? the whole gasket itself? or just the cover gasket?

*danesjr,
yep I'll be changing into an OEM cover gasket, but I dont know if that would resolve the Problem..

Still OT: on the part of Distributor leak? does that mean that my O-rings are worned out?

as i've said, it depends on where the oil is leaking.

the dist has an o-ring outside (can be seen easily) and an oil seal inside which can be inspected only by dismantling the assembly.

good idea to replace the pcv na. also it should not be too hard to get an oem gasket naman. just go to mazda mismo and get from them.
