Supra TT headgasket install ?
I'm starting headgasket Install today (yes i will include these pics in my na-t guide). Is it bad not to replace valve stem seals or any other seals when changing the headgasket? When I start the car I get NO white or grey smoke of any kind..If I rev it quite high I can get a little darker colored exhaust smoke, but you have to look for it to see it...i'm hoping it's just because I gutted the catolytic converters. What do you guys think?

I am putting in a TT headgasket today or tomorrow as well. I was going to pay A little over $275 to have a valve job done, but I put it into perspective for myself. I'm probably not keeping this car for another 160k, let alone another 10k or 20k, so to me its not worth doing a valve job on this engine. I'd much rather save it and put some money into something else.
So just decide whether its worth the extra money while you're in there. But no, its not going to cause damage not to.

The only time I can tell my valve seals are shot is when its cold outside. Even with the car warmed up, when I come to a stop and let it idle for a little while, it starts smoking. Doesnt do it if its over about 70 degrees. Generally Id blow that off as something besides the stem seals, but after seeing the rest of toyota rubber products fail miserable I have no question that they are shot.

Ha, mine's sitting apart in my garage right now waiting for the head to be resurfaced. Just LMK if you need any help connecting all those vacuum tubes when you're putting it backtogether. That was a mess...

Thanks, i'll probably take you up on that offer . I'm just curious are you still on original water pump? I'm wondering if I can get away without replacing that too since a Lexus master mechanic I trust said they don't need to be replaced until 120,000 miles usually. Also, what spark plug gap do you plan on using? I want those denso iridiums in the ngk 3330 heat range but not sure which gap is best for our compression setups.

I didnt look into changing the gap at all, I didnt even think about it, so I'm not sure what to do there.I replaced my waterpump because it was leaking at 150k, I have no idea if it was changed before that. My dad changed it again at 155k, when my timing belt shredded (i figured out later I dropped a screw in the case). But for $60 for a waterpump on rockauto.com, I'd go ahead and do it.

TMaxxTim, thank you it worked! Although, it's taking a while to drain through that small hose. The service manual says to undo a coolant plug on the passenger side of the engine block. Is this it?

A cap & Rotor on rockauto.com is only $14. I'm replacing mine, although I'm not sure when the last time it was replaced, could be 160k old although it doesn't look like it.
