Yes, it is very hard to change the plugs. Your lexus also likely has coils on top of the plugs, which you especially don't want to break. I would recommend taking the car into a dealer for the repair.

Hi, You need a new Spark Plugs Spark Plug Wrench Socket wrench Extension (At least 2-3 inch) size 10 socket size 12 socket...
First thing you need to do is find out where the spark plug cover is. Once you figure that out there will probably be size 10 or/and 12 bolts honding it down. Take that off and there you will see sensors connecting to each other and holding the spark plug in the cylinders. Unplug all the sensors and pull out the circular plugs holding the spark plugs down. THey might be a little tight and hard to get out so you're going to need to give it a good tug. Once you pull them out MAKE SURE YOU DONT DROP ANYTHING INTO THE CYLINDERS. You can look down into them and see the spark plugs. Get your spark plug wrench, extension, and socket wrench and stick them down in and push so that the spark plug wrench grabs them. Just simply unscrew the plugs, pull them all out, and then put the next ones in, and tighten them down. Just connect all the sensors, and put the cover back on and you're done. Pretty simple.
Take care

How do i change the spark plugs on a 2000 gs 300?


On top the cam cover, there will be a plate, its removable. It (on some models) has VVTI 24V , anyway it runs down the center of the cam cover. Underneath, after removal will be 6 individual coils, remove one coil to gain access to each individual spark plug. Do it one at a time, to lessen the chance of dropping anything in the narrow sections.

Let us know if you have something more to know else accept the suggestion.

I want to know how to replace spark plugs on a 2003 lexus gs300

on this particular engine, you are able to get to a couple of the plugs with no trouble. in order to get to the rest u have to remove the intake manifold; not as hard as it sounds only about 5-10 bolts. then just use a spark plug socket with an extension prefer locking extension.

hope this helps

Spark plugs

Who ever told you it was the Valve cover gaskets was correct. On the valve cover gasket around where the spark plug goes down though the head there is a seal made onto the valve cover gasket called the spark plug well seals. when replacing the valve cover gasket it will come with these seals and it will take care of your oil leaking into spark plug holes. Hope this has helped and if you need anymore assistance I would love to help.
