CAM COVER BILLET HALF MOON RB RUBBER REPLACEMENTS

[PLYNX]

Has anyone used the billet half-moons that are available to replace the rubber ones at the back of RB cam covers ? 

Going to change out my cam cover seals as they are weeping oil and its now driving me nuts.

Any advantage to be found ?

I guess the main advantage is that they start out hard and incompressible, so you can throw them away immediately, rather than waiting until they've done 50k km or something?

AFAIK on most Toyotas that half moon is usually an aluminum piece that you seal with RTV so you just source the valve cover gasket but I kind of doubt that you'll ever save money buying an aftermarket piece in this scenario.

I wouldn't go near them, they are rubber seals for a reason. Just chuck new cam cover seals, half moons and the spacers for the screws every decade or two.

I add a really thin layer of silicone too and it seems to hold together OK

@PLYNX I can help source the OEM shit for you for less, slide into my DMs.

Tried them, they leaked. I also foolishly bought some random rubber ones that leaked too. 

Genuine and not looked back. 

 

As always though sample size of one, and I could have made a mistake installing them.

I run them with no issues. I switched after having issues with rubber ones, so thought I’d give it a try. So far after several years no more leaks..

I use Taaarks/efi solutions ones. Years, and no issues.
