darsdoug Posted May 15, 2013 Share Posted May 15, 2013 Is this the correct cam tower o-ring for my ea82? I'm describing the o-ring that goes between the cam tower and the head? They were not labeled and were packaged in small manila envelopes inside the Felpro head gasket set I bought. I'm wondering about it now because there were three or four of them included in the head set. Link to comment Share on other sites More sharing options...
91_EJ_22 Posted May 15, 2013 Share Posted May 15, 2013 the ones ive see from subaru have a copper center inside the rubber Link to comment Share on other sites More sharing options...
NorthWet Posted May 15, 2013 Share Posted May 15, 2013 Pretty certain that is used for something else. (Though I can't think of what would take 3 or 4... you could look on the FelPro package's contents list.) The proper gaskets, which I have never personally seen in a FelPro set, are flat metal washers that are coated in rubber. Link to comment Share on other sites More sharing options...
MilesFox Posted May 15, 2013 Share Posted May 15, 2013 Thise appear to be injector seals for ea82 mpfi.The cam tower o-ring would be the size of a dime Link to comment Share on other sites More sharing options...
darsdoug Posted May 15, 2013 Author Share Posted May 15, 2013 oops. It seems to be running good? I know they had to squish down a little when I tightened the cam tower bolts. I'll have to get the proper seals. Link to comment Share on other sites More sharing options...
scoobiedubie Posted May 15, 2013 Share Posted May 15, 2013 oops. It seems to be running good? I know they had to squish down a little when I tightened the cam tower bolts. I'll have to get the proper seals. If they were not high temperature rated O-rings, then they will melt under high oil temperatures, and seep into the oil port in the direction of flow. Been there, done that. Link to comment Share on other sites More sharing options...
rdweninger Posted May 15, 2013 Share Posted May 15, 2013 Do you mean you installed them in your cam towers already? If so... yes... it will run ok. But as stated above... Bad things are happening. You just can't see it. Link to comment Share on other sites More sharing options...
darsdoug Posted May 16, 2013 Author Share Posted May 16, 2013 Thanks for your input. I HAVE noticed that my oil pressure is generally higher than it's ever been. e.g. 45 lbs @ 1000 RPM and 70-80 lbs @ 2000 RPM. Could restricted oil passages going to the cam towers cause that? I think I'll put a cup of used motor oil from my ea82 in a tin can and boil this remaining seal atop my coleman stove out in the middle of our local gravel pit just to see what happens. I better get a fire extinguisher first though. duh. I couldn't check the Felpro package list because the garbage man had already ran off with it.

idosubaru Posted May 16, 2013 Share Posted May 16, 2013 those are fuel injector orings/seals. Link to comment Share on other sites More sharing options...
darsdoug Posted May 16, 2013 Author Share Posted May 16, 2013 Great. I should have read the Felpro package contents sticker. Oh well. I'll go to Subaru and see if I can get the correct seals. I'm just not the brightest bulb in Seattle. ha ha. Link to comment Share on other sites More sharing options...
NorthWet Posted May 16, 2013 Share Posted May 16, 2013 I should have a dozen or so. If Subaru will take longer than Snail-mail, it might be worth having me mail a pair to you. Link to comment Share on other sites More sharing options...

The proper gaskets, which I have never personally seen in a FelPro set, are flat metal washers that are coated in rubber. The old original one's I took out were thin and hard and brittle and snapped in half when I tried bending them. I didn't detect any sign of metal in them. Hmmm?

NorthWet Posted May 17, 2013 Share Posted May 17, 2013 From what I understand from my betters, the metal reinforced gasket was introduced sometime during the production run, and obsoleted the previously used rubber-only gasket. 1 Link to comment Share on other sites More sharing options...
darsdoug Posted May 17, 2013 Author Share Posted May 17, 2013 I've boiled it in water and also squished it in a vice but it bounces right back with no effect. Felpro could no-doubt have info on it also? Link to comment Share on other sites More sharing options...
scoobiedubie Posted May 17, 2013 Share Posted May 17, 2013 Just buy a couple of genuine Subaru O-rings and you will see the difference. The engine gets hotter than boiled water. Your engine will tell you when you better fix the problem, when it gets louder from the oil being choked off from getting to the hydraulic lifters.

NorthWet Posted May 18, 2013 Share Posted May 18, 2013 Per your PM, I pulled a couple seals from my stash-o-parts. For those who may need to find the part number for these specials seals, the Subaru Part Number and Description are: 13089AA010 "O Ring - CMS Case" 1 Link to comment Share on other sites More sharing options...
idosubaru Posted May 19, 2013 Share Posted May 19, 2013 thepartsbin.com used to, and probably still does, carry those. but they're only $2.13 (or so) from the dealer... Link to comment Share on other sites More sharing options...
NorthWet Posted May 19, 2013 Share Posted May 19, 2013 My local dealer tends to not stock stuff like these. Sometimes a pain to wait a week. Link to comment Share on other sites More sharing options...
darsdoug Posted May 19, 2013 Author Share Posted May 19, 2013 I've gone 428 miles so far with no problems. I'm amazed at how good it's been running as it was my first rodeo on a ea82 HG install. It had the common hairline cracks between the valve seats on every cylinder but I went with it anyway after researching the issue here on usmb. I did put a coat of copper spray on the HG's and I put about 3 ft. lbs. of extra torque on each head bolt after going thru the third torque sequence.

NorthWet Posted May 23, 2013 Share Posted May 23, 2013 You are welcome. I have yet to see an aftermarket head set that has these... at least these correct ones. Link to comment Share on other sites More sharing options...
darsdoug Posted June 1, 2013 Author Share Posted June 1, 2013 I've clocked 887 miles so far since the HG replacement and its still running pristine. I better get some ambition and put the seals in. Link to comment Share on other sites More sharing options...

darsdoug Posted July 4, 2013 Author Share Posted July 4, 2013 Update: 2,147 miles and still running strong. I've been busy at work and haven't installed the correct cam tower oil seals yet.
