Help guys! Valve stem seals....

[SupraClaou]

Just got some new ferrea valve stem seals but I got all 24 of them in one
small nylon bag...
I heard there are 12 intake and 12 exhaust valve stem seals.
How can I find which ones are for the int / exh ???

If you want me to post up a picture,please let me know..
Thanks!

theyre the same

I did not think they are the same... For some reson, I believe that there is a minor color or length difference. I remember getting ready to do these myself on one of my 2J GE heads and somewhere on Supraforms MKIV section, they had a write-up that said something along these lines.

I'd doublecheck before getting started. I may be wrong, but since you only get 24 in the set, you can't be wrong or mess a single one of them up.

I heard that the only difference of the oem toyota seals is that the exhaust
valve stems seals are more durable to heat.
But it seams that ferrea makes both intake/exhaust from the same durable
material.

What you think guys?

ive done the stem seals on mine 3 times (im anal, and i had the head off the motor and apart anyways) and i never noticed a difference on them

The stock Toyota seals are different, intake and exhaust, they are slightly different color and one has an extra lip on the inside if I recal corectly. But I am not sure about the Ferrera seals, I have never used them. If you look closley can you see any difference?

I have 3 sets at home and can check 'em later and post what I find. I just did a quick search on SF and can't find the write-up where I thought I saw what the difference is.

I ordered the Blue Viton seals and all 24 are the same.

Some how-to info linked below. One of them said that they had 12 seals which used a dark brown rubber and the other 12 was black rubber. I dunno if that's the stock setup, but the ones I have at home are the viton ones as well and may be the same for intake and exhaust.

Will let ya know what I find when I get home later.

Used this method on 7M heads 3 times,no worries, but a PITA. Must have a very understanding partner/wife/girlfriend. and lots of beer.:naughty:

Used Viton seals the last time(IMO the best) and no problems since, related to valve stem seals.

This is in reference to a 2JZ, no? The Ferrea part numbers going off memory are VS1008 and VS1009. The VS1008 is the exhaust seal, the 9 is the intake seal. They do differentiate between the two, at least enough for them to create a second number.

Now in regards to the Toyota seals, I don't know if they differentiate because we always order Ferrea for the 2JZ cars. I did order two sets of 7M seals today for customers from Toyota and they were a single part number, nothing different between intake and exhaust.

The viton seals I got with an aftermarket gasket set are slightly different (just checked). There are 12 which are somewhat grey (gray) and 12 which appear "copper'ish." just a tad darker than the grey (gray).

If yours all appear EXACTLY he same, then you should be allright.

My question is a little off topic, but I'm currently doing the valve stem seals on my 1jz and I have been measuring my valve's free lengths and I keep getting over 44mm. The 2jz tsrm says it should be 41.74mm. Do y'all think there is something wrong or am I doing something wrong?
