I am digging in and removing the heat exchangers and was wondering if there are any tricks or things to watch for? I don't want to damage the heads in the process. (IMG:style_emoticons/default/confused24.gif)

Done. All nuts came out easy. There were no washers in there, are there supposed to be? The nuts also were not very tight.

They were probably loose because they were the wrong kind of nuts. Don't use washers. But do use the correct nuts: Exhaust Stud Nuts Don't over tighten the nuts when installing or you'll strip the threads for the studs. I think 18 ft lbs is the correct amount, but check the Haynes manual to be sure. |
