As the title says really chaps. Other than the PCV valve angle, is there any other differences between the two covers?
If you changed the PCV valve to the MY04+ version, could you fit the MY04 cover on an MY03 engine?

...Bored in work, so reading about things in the 'Under the hood section' is causing me to think.

 

I wish there was more info on this too - especially if you decide to run turbo & have a catch canister to replace the PCV. Spoon even have an elongated cover they sell but relatively little info on it.

 

Probably costs a fortune too.

 

Just incredible that given the popularity of polished/painted rocker covers & catch cans, that nobody produces an off the shelf one.

 

My reasoning behind the whole thing is this oil burning issue with the <MY03's.

The boys in the US reckon it may be something to do with the breather and PCV valve section causing oil to be sucked up into the air intake, so have been fitting all manner of bits to try and stop it.
No one seems to have thought about simply changing the rocker cover. I can't see any pictures of the inside anywhere, and the only difference on the outside seems to be the PCV valve angle.

I was thinking of picking up one from a breakers and seeing if it reduces the oil burn, but don;t want to fit one, if the clearances are different and the engine eats itself.

 

I'll let other people trial it, then make a decision from there. Personally I'm swaying towards no breather back into the inlet to try and simplify things & having a separate, easily accessible & serviceable catch can next to the water bottle - moddiction springs to mind as a decent contender.

Still interested in the subject given that I drive a MY00

 

I'm experimenting with different breather setup's at the moment. I'm sure the guys with <MY03's are welding baffle plates over the internal PCV inlet inside the rocker cover and that is preventing the splash absorption.

In answer to the original question though. No other changes I am aware of.... at the end of the day what sits underneath it hasn't changed so why should it matter?

 

The thing is N/A an oil catch can wont really reduce oil consumption THAT much, the reciculated oil/blowby is now trapped in your catch can, when standard its simply just put back into the engine to be burnt up. Majority of the contents of a catch can is water vapour due to cold morning, vapour in the system and cooling/heating up. What a CC does though is reduce DET due to reduction of contamination in the air (with slight oil in if any) and hence push more timing and thus more power, but its probably small. Look at where the front breather hose goes too.

If your PCV valve was clogged then yes it could effect oil consumption somewhat, running a CC also helps to reduce caking up of your TB etc too.

I run a custom catch on my SC setup, its full system whereby it diverts both breather hoses, caps off at the intake manifold and intake pipe and has a breather ontop - i can post a pic if you wish?

MY03 and MY04 covers are interchangeable.

Later DBW S2000 valve covers will not work on earlier cars.

I've posted about this before along with part numbers etc.

Chris.

 

Thanks for the explanation AJ - I wondered if a catch can would actually do anything, but as you said, I thought it would just cause the oil to actually pool somewhere (and i wouldn't want to put that back in to the oilpan anyway!)

Chris - just the answer I was looking for! I might get on to a breakers and see what the cost would be.
Has anyone got a diagram of what needs to come off when you take the engine cover off? (Tried a search, but all the photos were missing).

Cheers all,

Andy
