Oil in Spark Plug Wells

gaitski · 03-15-2011, 01:36 PM

Yeah, I want to understand what I'm doing as well. You're right, I wouldn't expect to find the individual bolt gaskets in the Toyota catalog. I read on the post that I linked in my first post that the #3 cover has a built in gasket that seemed (to that guy) to be a bad design. He recommended bringing one of those 14mm bolts in to the parts shop and matching it up with an oil plug gasket since that's where the oil is coming up from.

I appreciate your responses, I'm definitely new to this and would like to get different opinions. Thanks again!

The only thing on them for a gasket is a crush washer like the type used for an oil drain plug. If you use the use some sort of liquid gasket on the threads before you reinstall them they won't leak anymore. But as for the need of the cover, I don't understand why cre would get so upset. I don't use mine anymore so I can see if any of the plugs do start to leak again. But the cover does not stop oil or coolant from still getting in the valley and besides there is nothing that the cover covers that is that important. Also what debris is going to get in there anyway unless you are driving offroad with the hood off.

Ok, I've got a follow-up issue now. While trying to remove the 3/4" hose from the No. 1 head cover, the hose tore. It was crazy brittle, so I'm glad I'm in there and can replace it now, but what is it? It travels from right next to the oil cap down to the block, but I can't find the thing on the Cygnus site.

I also heard something small and metallic fall down below when the hose tore, and it wasn't the hose clamp....any thoughts?

Thanks again!

I think it's the crank case vent hose

As Sonyps307 said " crank vent hose # 3" Toyota part # 12263-42010, judging by your description is sounds like the hose clamp fell down, although you did say it wasn't the hose clamp.

Awesome, thanks guys that definitely looks like the one, and I'm still guessing as to what fell down...
