I was looking around the engine and I noticed that right below thecam chain tensioner on the rear of the motor there is a half circle which looks like the half circle below the valve cover which is filled in by a gasket that I just replaced. When I stick my finger in the half circle below thecam chain tensioner i feel the gasket but its sticking in about 1/2 inch. Should the cam chain tensioner gasket be sitting flush with the head like the valve cover gasket is. I wish I could get my pictures to upload. But all of you who have replaced these gaskets will know what I'm talking about. Thanks

 

is there a problem? is anything leaking? try to get a picture and i could help you..... or what would you be replacing wich in turn would make you have to RR that piece....

 

If your looking at it from the back of the head there should be about a 1/2 gap yes, the half moon seal sitts in a little crevice thats directly below the chain tensioner. Some people actually fill the gap with sealant as a cheap fix for oil leaks.

 

I am in the process of replacing the valve cover gaskets and the cam chain tensioner gaskets. I have never done this before and I am having troubles. Do I have to completely remove the tensioners, and if I do, how do I get them out? I tried a search, but after an hour of looking with no success, I am getting very frustrated. If someone could give me step-by-step instructions or show me where some instructions are, I would greatly appreciate it. Thanks, Joe
