1458725 2019-03-04 21:36:00 I replaced a valve cover gasket on my old Ford Laser , 1 week later its leaking more oil than before . Its now dripping out onto the driveway .
It was a thick rubber gasket, so I assumed it didnt need any gasket goop.

I havnt had a chance to see where the oil is now leaking from, Im assuming its the new gasket, might not be
If its not an easily replaceable gasket leaking oil , it could be too expensive to fix (?)
It may fail its WOF if the garage deem it to be leaking too much.

So, do I need to put gasket goop on new gaskets ? On both sides ?
if so, any particular goop for rubber gaskets ?

Was recommended to put gasket sealer on the abrupt turns where it goes over the cam drive Also important to follow the tightening sequence and Torque settings

1458727 2019-03-04 23:08:00 I dont think you would need any gasket compound with a rubber gasket, the problem with valve gear gaskets is they need to be tightened down in a cross sequence a little bit at a time. I used to put grease on a cork gasket being a Jew so if I took the cover off the gasket wouldnt stick and break and could be reused. prefect (6291)
1458728 2019-03-05 02:43:00 I don't like the thick rubber gaskets since they tend to squish out of the place where they need to be - especially if there's any kind of goop on it .

If I were to have to use a thick rubber or cork or composite gasket, I'd prefer to use a spray contact cement that dries and once the gasket even touches the valve cover, it's there forever!

Actually, with the advent of RTV Silicon 'Gasket maker' type sealants - I don't use anything but the silicone room-temperature vulcanizing stuff as the only seal material .

The copper- colored RTV is for exhaust manifolds and header gasket replacements .


The Black RTV is typically for oil pans and valve covers .
The Red RTV is for objects that get gasoline or coolant on them .
The Blue RTV I use for diesel applications .
The Clear & White RTV is for sinks, tubs and shower stalls, not automotive .

I've practically built entire engines with this stuff - except for the head gaskets, of course!

It has a channel cut into the valve cover that the thick gasket sits in . It wasnt going anywhere . :)
The workshop manual didnt give any torque settings for the valve cover, so I guessed it, and did the usual star sort of tightening pattern .

Could it just need a re-tighening as the rather thick rubber squishes down ?

Its only $20 for another gasket, so I may just re-do it with some goop this time . Fingers crossed its not leaking from somewhere else .

If I can smell it, does that mean the oil leak has to be running down across the exhaust manifold ?

1458730 2019-03-05 03:23:00 Leaking oil can hit the exhaust crossover - if you have one.

Or it may be running onto the catalytic convertor - or pretty much anywhere the exhaust system is - or exists, that is.

Did I miss seeing what type of engine this is?
Ford Laser doesn't work here as an identification in the US.
It sounds like the valve cover is cast aluminum and has a channel for the gasket - and as such it should not squish out.
Were the channels clean?

But I have no Idea if that continued.

When they are removed they usually break or have broken and allow oil to escape

Its a rebranded , lower speced Mazda 323/Familia .
Supposedly, the Mazda's were made in Japan, the Fords in Korea (or an old wives tale ? )

NZ, being clean & green, didnt require or fit Cat Converters back then. :)
