Hi all,

 

Thats the USRM in the link above. I put that up a while back when my ASV blew up.

 

Since you have provided a picture of your blown hoses I know which side it is, the drivers side.

 

My ASV was the more fancy one but I took the new reed valve internals out and put them in my old Valve assembly. The reeds broke down inside the valve.

 

I intended to put up the EA81 ASV scans but never got around to it. Sorry. The scan on the page is the EA82 pages. Yes the early carb models had the ASV.

 

New Reed flaps are pn 460147300 and are $53. This is the broken piece within the ASV only and not the whole ASV.

 

For the whole ASV:

For some reason, they list a dealer part number of 469907300 in my parts book but then somebody hand wrote a SPS377200 next to it.

The 469907300 lists for ~200 or $153.61 on Subaruparts.com

the SPS377200 comes up on their site as $12.67 or $16.61 list.

 

Me thinks I would take my chances in ordering the SPS part , or get a used one and do Qman's trick.

 

Sorry I never finished my USRM submission. Mick has been doing the updating on the site for a while now and I havent taken over again yet.

 

Thanks

Shawn

The SPS number is the same as what I have on the two I bought from Smart Service (see my earlier post on page 1 of this thread). 'Opened the new ones up and removed the reed valve portion and installed it in the old housing. Works just fine.

A couple of weeks ago I took a trip from Boise to Portland. A loud growl started emanating from the engine compartment. The further I drove the louder it got. Upon arriving back in Boise I discovered the aforementioned "Chernobylled Silencer."

 

I took the whole mess out and sure enough the ASV was internally busted. I think I was lucky though since I only found two tiny pieces of melted plasic near my carb intake. I think the hole in the silencer was big enough to let most of the exhaust gasses out. Soob still runs fine.

 

So it's off to my local secret pull yard to harvest parts from hush-hush stash of wrecked Soobs. Yeay!

 

This thread is brilliantly helpful, BTW.

This thread is brilliantly helpful, BTW.

Yes, and extremely old.

It is really great though since he used the search, found the topic and then brought the old good information up for viewing again.

So if I can't replace the ASV right now it would be a good idea to get a piece of screen and put it over the top of the carb? Then none of the pieces of the burned up ASV would get in the carb, right?

Absolutely Shawn - at least we didn't have to rehash it.

 

To answer Goatman - use a quarter, and stick it in the ASV pipe comming up from the head where it screws into the valve. This will disable the system, and then you won't have to worry about it blowing on you. Only take the quarter out if you need to go through emmissions later. Only takes about 20 minutes to put the quarter in....

Pull the rubber hose off at the end of the air cleaner and at the end of the ASV and just run without the hose until you can get a hold of one.

 

 

I can send you some used ASV's if you have an ea81. Personally the $12 is worth it IMO.

Sorry for resurrecting a dead post, but someone else asked too, Do EA82 engines have 2 air suction valves? Or can they just have 1, or even none? You guys only mention the ea81.

Yes, they have em on the Carb'd engines and usually 2 on the ea82's.
