20V stem seals

[Vezza]

Hey guys,
Just looking at changing out the 20V stem seals. Got a price from Toyota at $266 for a full set, ouch! Going to ring up Fabre tomorrow and see if they can do it cheaper. Would anyone know of anywhere less pricey?

Also, I've read the 20V head can be quite difficult when it comes to removing the spring retainer (with head on block). From what I understand it's because the diameter of the spring and hole it sits in is quite small and most tools won't fit in. The type of spring compressor i've got consists of two legs which hook onto the spring and allows you to wind down a hollow circular bit over the retainers.
My question is, how small a diameter will the hollow circular bit need to be to fit in the spring hole? Also, will the legs be able to hook onto the spring or are they quite deep, requiring the use of a push type tool?

I know I could find out by opening up the motor, but I really want to get this done in one day, with all the right tools there.

Go to a machine shop that has worked on 20 valves, and beg then to borrow a tool. You may have to make a tool from scratch. If the legs of a spring compressor won't get down the hole to the spring, then you need to use a different sort. Like a big lever that just pushs down on the spring retainer.

If the head is on the car, you may want to put compressed air down the spark plug hole. I have a hose made up for this, that screws in. make sure both valves are closed. If the piston is at the top, the air will try and push the motor around with the piston at the bottom. So if you want the piston at the top, then put the motor in gear or something once in position. The air is to stop the valves dropping into the motor of course.

I did this job on a Mazda or something a few weeks ago.

Stuff a rag in any oil drain holes, because when the spring collors drop or go flying, they can go down the oil return holes into the sump in some motors, or get stuck half way.

I use a motorcycle valve spring compressor tool, easy to come across, makes the job easy as. Check ABW catalog.

I recently did a 20V head(but engine was disasemmbled), valve stem seals came in gasket set.

I rang up Fabre and they could do a set of stem seals for around 60 to 70 bucks, posted! Glad I gave them a call before going ahead with the Toyota seals. From what other people were saying, it seemed almost impossible to get non genuine seals... hope they're good though.

Yeah I'll give the ABW catalog a look up. If I can't get a hold of a tool guess I'll just machine the side of a deep socket out and stick a couple of magnets around it.

EDIT: Hey Frak, was this the tool you used on the 20V head? Pretty cheap.

Any update ?

Did you buy the valve stem seals and get it installed ?

Cheers

I've bought the stem seals, but waiting for the tool. Hopefully it arrives tomorrow. I'll do a full write up with pics and what not when I do em.

Oh and I ended up getting the seals for $35!! Cos our currency has bounced back against the american dollar! Thats a far cry from the $250 or so Toyota was asking....

As the saying goes, you get what you pay for.

I hope it works for you thou.

$35 sounds too cheap. there is 20 of them afterall

[Vezza]

True. However oem Toyota rubber brake lines cost me $189 and I know AJPS sells ADR approved braided ones for $180.

But the cheapness of the seals came down to the currency conversion. Would've been around $100 back in the day... well here's hoping their good anyways haha.
