What Are Tapper Covers?

[Scooby_Steve]

Hi All,

Just wondering if someone could clarify what a tapper cover is?

Are they the covers that sit next to the valley cover (the cover that covers the coil packs and spark plugs)?

The reason why i ask is that it seems to be leaking a bit of oil there and i think i need gaskets/seals. Anyone know where i can buy some?

thanks.

yeah, it's called rocker covers/cam covers. I dont think they actually use a seal. there may be a rubber o-ring there, but they are probably just sealed using liquid gasket. you can get the good stuff from nissan.

Hi,

thanks... So just liquid gasket will do? I just thought that if there were a gasket, i'd just buy one. I looked in the service manual and it says that there is a gasket..

Any more help would be great. thanks

of couse they use a seal

its a rubber seal that sits in the grooved section of the rocker cover

for best results, use in combination with permatex number 1 and you will have no leaks... also check how tight the screws are continually, as they work themselves free from vibration

Will try that too!!

there are rubber seals under the covers, half moon shaped seals at the back and seals over the front of the cam. Any of them could leak but it is most often the half moon seals at the back.

Hi All,

Its a good chance that i'll need replacement seals however i did go to tighten the bolts and every single one of them needed to be turned 2-3 times each before they went tight.

I dont know if this was the cause or whether it was because the washers have worn away, thus reason why i was able to turn the bolts a couple of times before it was tighten.

OK just be a bit careful with those seals they are not meant to be tight. the 32 gtr workshop manual says only 4nm, otherwise you can pinch or crack the rubber seals and make it worse.
