ono8ono Posted August 10, 2008 Share Posted August 10, 2008 hey guys, some of you may have this same problem: oil leaks from the valve cover on both side. And the oil leaks to the exhaust and smell kind of bad; I wonder how difficult to replace the gasket; I know there is a write up at lexLS.com but that is for '90-'94 LS engine. do you know any write up for '98 LS400? Thank you in advance. :) Quote Link to comment Share on other sites More sharing options...
Harky Posted August 10, 2008 Share Posted August 10, 2008 I had the same problem...cured it by snugging down the valve cover screws. Some of the screws on mine were just finger tight. Gently!! tighten them in a sequencial pattern all the way around a little at a time. Look closely with a flashlight so you don't miss any.
