Found myself a plastic cam cover from a Vectra C or something. It's 1.8 kg less weight then the alu cam cover so nice and easy you think.

Some folks said it's a direct swap. others said it wasn't.

 

Now to clear things up here's the deal:

 

Below the OEM situation. You can clearly see that the rubber ring is sitting on top of it's surrounding.

 

 

Now I removed the rubber ring and placed it in the plastic cam cover:

You can see it drops in/below the surrounding.

 

 

Now I don't think that last pic is a good way of sealing the plughole. Am I right? How did other people manage this?

When looking for the cam cover gasket set, they mostly turn up with the same partnumber as the Z22SE cam cover gasket set. Confused I say...

 

Let me hear you!

I have a plastic one to go on at some point, so interested in hearing the answer to this. Though it may depend what year your one came off, but i could be wrong

You need a diffrent gasket to the metal rocker cover its completely different .This will fit the plastic cover  .

I've just taken delivery of one. Came with the bolts and gasket so hopefully it won't leak!

[TFD]

I replaced the bolts with new ones and you can get rubber 0-rings (19mm OD/8M ID/ 3mm thick) from Ebay to replace the thick rubbers.

What a man's got to do for 1.8 kg of weigthsaving lol

 

Anyway, every little saving counts.

Ti complete the topic.

Ordered the gasketset:


Bored out the cranckventpipe. The alu is 7mm ID and the plastic is 6mm ID. Used a 8mm drill to optimise the flow.

Finished product with new bolts and stuff:

1.8 kg of weight saving ? 1.3 at best !

[Zoobeef]

I'll be fitting mine tomorrow and will weigh it.

[TFD]

@2-20: Used new shorter and lighter bolts and all stuff together weighted in at exactly 1.8 kg difference. The scales are in at 100 gram so could be 0.1 kg less or more.

Edit: weighting was without the gasket for the plastic one but with the gssket on the alu one... Damn. So extract the weight of the alu gasket.

Jeez I can loose 2kg by having a decent dump in the bog!

[2-20]

My records are 3512 g métal 2136 g plastic But i did not weigh them by myself so you are probably right

[Zoobeef]

Jeez I can loose 2kg by having a decent dump in the bog!

 

I'll be doing that also.

[Zoobeef]

Just weighed the plastic. It's 2382g, that's with the earthing bar and oil filler cap included.

[TFD]

You're definitely using a more accurate weightscale than I am displaying the weight in grams lol..

[Zoobeef]

Metal is 3702g Inc oil filler cap.

[2-20]

So 1320 g of weight saving

[Zoobeef]

Yeah, also taken off the engine lifting eyes and a few other brackets so I'm at 2.2kg removed so far.

Hopefully Plastic4performance will hurry up with my polycarbonate windows.
