i have a 94 teg LS and it burns tons of oil, can go through the hole tank in a few days depending on driving. i herd it could only be scared cylinder walls, my rings , or a leaky valve train, well i had a compression test done and all cylinders had full compression so the guy said it eliminated cylinder walls and rings, wut could it be? im goin 2 try to get some head work done i guess. any help would be greatly appreciated!

 

valve seals...im having the same prob on my da9 also...and still trying to research on how to replace the valve seals...

 

you need a leakdown test, mostlikly ring or seals, either way the heads coming off, teggytegteg you can do it with the head on, but how do you know thats what it is? i mean really?

 

fromGoing by my Helms (which is for a b18a BTW) you do not have to remove the head.


#2 & 3 are the valve seals (crappy picture I know)


However, you will need a couple special tools for the job.
-First off you'll nee a HELMS manual (of course) to give you all the specs.
-next you will need an air compressor adapter to connect an air hose to your spark plug hole. this will pressurize the cylinder and keep the valves in place when you pull the springs and retainers.
-You will also need a valve spring compressor, the specific type will be in your HELMS.
-Finally you will need a valve guide seal puller. again the specific type will be in your HELMS.
****Caution******
valve keepers will fall down oil return holes and may get stuck in the engine. block these holes off with a rag!
****Caution******
you will need to use compressed air to keep the valves in place. exercise caution and protect your eyes from debris and oil spray.

Along the way I would do an inspection on each of the components you pull out. look for waer and damage and verify they meet the proper specs.


The basic steps
1-position piston at 1&4 at TDC.
2-Remove valve cover, distributor, Timing belt and cams
3-install valve spring compression tool.
4-Ensure piston for the cylinder you are working on is at TDC. This will save you a lot of pain if a valve falls in!
5-hook up air line to sparkplug hole and pressurize cylinder
6-carefully remove springs, retainers and keepers.
7-Repeat above step for the other valve in the cylinder.
***Warning!! once the springs are off the air pressure is keeping the valves in place. Loss of pressure could cause the valves to fall into the chamber.
8-Install valve seal puller and PULL those puppies out.
9-Replace with new valve guides and drive down to proper height. Specs are in your HELMS manual.
10-Reinstall springs, keepers and retainers for each valve.
11- Repeat steps 4 thru 10 on each cylinder on the Intake side, then do steps 3-11 for the exhaust side.


When you are all done I suggest using some Seafoam or Honda head cleaner. I'm sure your sh*t is all gunked up, so cleaning it out would probably help.
this is from TI, get the helms for pics

 

pull ur sparkplugs out and see if u got oil on them. if u do, all u will need is the valve cover o-ring(s).

 

add some auto rx to it. i have used it on 6 engines that used stupid amounts of oil. its usually stuck oil control rings on the pistons. i last used it on a yamaha virago that the owner thought was totally shot. went from a quart every 200 to a pint in 1000. auto rx takes a while to work its magic. try it, its worth a shot.

here is a link to a oil website that talks about autorx. its the chit.
