Leaking Valve Covers (cam / rocker covers)

Recommended Posts

Hi all newbie here👋

 

Had a 350z for 4 year now and been through 2 new sets of rocker covers.

 

Cheap Ebay specials at first, started leaking towards the rear of engine and into spark plug tubes.

 

Expensive Tarmac sportz ones were the exact same.

 

Both sides have leaked at one point or another. New seals included in the covers and correct gasket material/seal has been used. There is not damage to the head that I can see after cleaning off the old sealant. Problem looks like the cover warping as they are not flat at all once removed. 

 

Can anyone help or have a solution? Or what's peoples opinions on the aluminium covers?

Are they genuine nissan or oe spec? 

Had nissan oem rocker covers fitted at tarmac in October and have no problems. 

 

I don't track the car though. If you do use it on track it might be worth looking at the aluminium ones as they are obviously more heat resistant and serviceable from what I've heard.
