What are Subaru valves made of?

[davebugs]

I'm planning on parting a bunch of heads to scrap. Mostly DOHC from engines that had HG and/or rod knock issues. 10 or 12 engines.

 

A bare DOHC head weighs just over 17lbs BTW which is about 10 bucks, bare intake weighs 13 lbs, etc.

 

I'm wondering if intake & exhaust are same material. And if it's worth anything special.

 

I have some from Saturns and VW's around but I'll have a decent amount of Subaru valves. Yes I realize they are small and light.

 

I am parting these engines. Mostly 97 DOHC's so if anyone needs heads, cams, stupid stuff like cam cap or their bolts, shims(from a 97 head), that kinda stuff PM me.

 

I usually sell the cam sprockets on Ebay along with harmonic balancers, IAC's, throttle bodies, AC & PS tensioners, timing belt covers, etc.

 

Weird stuff like brackets available, the metal lines under the intake, injector wireing, injectors, fuel rails, flex plate's, well you get the idea.

 

I used to save AC hoses because they are expensive but never labeled them. I sometimes would swap out the AC compressor and lines that matched. But if you need one and can gove me a pic I might have it. I only kept lines from cars that still held a charge.

 

Along with starters, alternators, doubt any good PS pumps.

 

But my question here is are the valves anything exotic and worth setting aside? I tried searching without success "valve material", "valve content", stuff like that.

 

If anyone lives close to Gary Gross I believe he's heading here in the next few weeks to pick up some other heads and would probably consider hauling other parts home for a member if necessary although I haven't asked him.

 

I'll start or update another thread because I do have Outback front bumper assy's, some rad assy's, some doors, etc too.

 

I believe the short blocks are spoken for.

 

All these engines ran when removed.

Hey Dave,

 

I don't know about EJ valves but with N/A EA the exhaust are stainless and on the Turbo models, both valves are stainless. Worth a bit more than scrap aluminum to me. Get your magnet out, and if it's barely magnetic with a super magnet, it's probably 304 stainless.

ej22t are sodium filled, and you need take precaution in handling, there is a service warning on it.

[Quidam]

Yea, good point, probably some WRX/STI stuff too.

VW 1.8t's have the sodium filled and require special handling.

 

I'll give some the magnet test tomorrow. I only have the "pickup" magnets for when I drop nuts/bolts on the floor. And some rather strong curved ones from an old VW starter.

 

Thanks for the idea.

intakes are aluminum and recyclable like the cross over pipes, i just took a load two weeks ago.

I'm amazed that aluminum could take the heat/pressures. Perhaps it's a "special" aluminim.

 

So you just got the same price/lb as cast aluminum then for the valves?

[The Dude]

I can't find a scrap value for it. But the Subaru crankshaft is a big honkin' piece of 4130 CroMo steel. That's fairly expensive, aircraft quality steel.

[davebugs]

The exhausts(I believe I forget) are magnetic, the intakes not.

 

Just had a fellow come pick un an excellent(no rust) 73 Bug carcass (it was wrecked but still lots usable). He came in a 56 Mack rollback - I like that old stuff!

 

While I was waiting I started breaking down another head and tried the magnet on both the valves. Frankly at some level I'm shocked they aren't the same material since the heat they are exposed to in the chamber is the same.

 

I believe I have the short blocks sold.

 

I have a thread asking how hard it is to break these engines the whole way down without a good response in time or tools for instance. Or if there is a specific road map of how to break it down. Nothing worse than doing something out of order and it causeing problems. Yea - I realize by the time I'm down to the short block there really aren't many parts left. But it would still be good to hear.

 

Perhaps I'll price what that crank scrap is worth. Due to the local steel and machining industry around here the places are used to taking some more exotic stuff in and I'd have to call around about who wold be interested(pay) for that crank if the blocks don't get sold.

actually i was surprised, they had multiple categories of aluminum - i had a large load of aluminum and he weighed it in 3 or 4 different batches based on type of aluminum, so there are differences, i just don't know what they are. i was surprised and asked if i had covered all the types, he said nah there were more?

 

the aluminum wheels were not weighed the the aluminum engine parts, whatever that means.

 

So you just got the same price/lb as cast aluminum then for the valves?

i didn't have any valves, i trash those in a big metal trash receptacle that just went with a huge load to the scrap yard for $7 per hundred.

Gary,

 

You need to bring your scrap my way after the holidays.

 

Clean alum down to .55(.60 last week - actually .51 to .60 depending on where), dirty alum blocks down to .15, batteries 5.00.

 

No special rate for Subaru cranks though - just probably 12.50 or so just like cars.

[idosubaru]

i just made a trip so i don't have much now, one engine block and maybe some odds and ends, i can bring them possible. close to your house?

 

i think alum was 35 cents a pound, they don't pay well down here, only $7 per 100 for scrap & whole cars. Pburgh must have better prices.

 

i have a large roll of 1"copper pipe or something, if i can't sell it locally, ebay, or craigslist maybe. maybe i'll bring it and see what it's worth.

[davebugs]

I go to 4 different places depending on what they are paying. All 15-20 miles from here.
