One of my friends offered to help me tackle this perpetual problem of my worn valve seals. I would never think about attempting this on my own, but he has a good deal of knowledge about this engine ( I bought the car off of him to begin with, he rebuilt the motor... but didn't change the seals... fail.) I did some searching and came up with a few things but not enough to really answer everything. Anyways, has anyone done this themselves? I would like to know what exactly I need to prepare for this, including the part number for the seals if anyone would be so kind as to source them. I'm 95% sure this is why i'm burning so much oil, not to mention my plugs get fouled within a few months.
I burn about 2 quarts a month and it is due time something is done about it. Thanks guys. PS: If someone is willing to help, I would drive to you in a heart beat -------------------- **If you play My Brute, joing the 6gc.net clan!**

tony, its quite an involved job to do the valve seals.
toyota normally charges ~800$ for the service. a quick rundown of whats involved goes somthing like this: you'll need to at the minimum remove the timing belt from the cam gear, remove the cam gear itself, and the cams, pull all the buckets (yes, you need to keep these in the correct order!!), then you need a way to keep the valves from falling into the cylinder when you remove the spring combo. thats where the air compressor comes in, you use the air from that, and fill the cylinder with air to keep the valves closed. then you can use a spring compressor of some type (Hurley97 works @ a toyota dealer, so she borrowed a cool tool that the master tech there made, to compress the springs and remove the keepers and retainers, pull the spring out, then pull the old valve seal out. a 10mm deep socket works well to press in the new seals, then reinstall the spring and retainer, and another specialty tool to install the keepers. 4X on each cylinder, (16 valves total) and then you can put the car back together. if your actually gonna do that, and your not sure when the last time things like the timing belt, water pump, cam seal, idler pully, and tensioner were replaced, you may want to at least inspect those peices and replace as needed as well, while its all apart. ATF does work sometimes, it causes the rubber to swell alittle, which can help stop leaks, although with the way our valve seals harden over the years i dont think it will help much if yours are as bad as they sound. -------------------- Former Team 5SFTE pro member ;)
