aircraft engineer Posted February 25, 2008 Share Posted February 25, 2008 How difficult is it to remove the cap (that holds the seal) over the end of the cam with the seal/sprocket drive? If I'm correct, it looks like 2 bolts hold it on (based on the pax side rear of engine - heads being interchangeable and all that). Any danger if I disconnect the cam sensor to take it out? Is there any gasket behind the junction that could leak? Any seal there or just use the anaerobic gasket maker on a metal-to-metal surface? I've got evidence of an oil leak somewhere right there (cam seal didn't appear leaking but I replaced it anyway). The oil saturated the rubber "gasket" behind the timing belt REAR cover (right behind the sprocket between the cover and the head) and that gasket has swelled so it won't "fit" (will replace it) I'm wondering if there is any connection between the sprocket not having the dowel pin "key" and the oil leak? (that oil seems to be coming somewhere in that area - and yeah, I'm replacing the valve cover gaskets - both sides - as well - that's "next") This isn't as bad a job as I thought it would be but these "different" things are slowing me a bit. Oil pump cover plate was loose on 3 screws so loctited all 5 with blue (no idea if the crank seal was "bad" but it got replaced anyway) maybe another 2 hours of work - only because I don't know this engine at all.

idosubaru Posted February 25, 2008 Share Posted February 25, 2008 yes cam cap comes off really easy, i've done a ton of them. there's an oring behind it that you'll want to replace with new. no problem removing the cam sensor, it just unplugs and unbolts. remove and reinstall and you're golden!

aircraft engineer Posted February 25, 2008 Author Share Posted February 25, 2008 all right - thanks. I got o-rings in the kit. That's only another 30 minutes of work Quote Link to comment Share on other sites More sharing options...
WAWalker Posted February 25, 2008 Share Posted February 25, 2008 There are three bolts holding the cam support on. Two 6mm and one 8mm. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted February 25, 2008 Share Posted February 25, 2008 Yes that o-ring is fairly straightforward replacement. You don't need any other sealant there, just the o-ring. Also there is the cam cap at the RH rear of the engine as well that takes another of the same o-rings. Quote Link to comment Share on other sites More sharing options...
Bigbusa Posted February 25, 2008 Share Posted February 25, 2008 I've got a pair of the o-rings. For the life of me, I couldn't figure out where they went. Luckily, now that I know where they go... I can see that the old ones aren't leaking. Quote Link to comment Share on other sites More sharing options...

aircraft engineer Posted February 26, 2008 Author Share Posted February 26, 2008 any offhanded chance of pulling out the cam when pulling off that seal cap? It seemed like it "moved" when I tried removing it so I just tightened everything back up and left it - of course, if it DOES leak, then I will need to pull it apart again anyway. :-\ Quote Link to comment Share on other sites More sharing options...
EVOthis Posted February 27, 2008 Share Posted February 27, 2008 if the engine is in the car i thought the cams could only be removed if the cylinder head was removed first....at least on the 2.2...... Quote Link to comment Share on other sites More sharing options...
idosubaru Posted February 27, 2008 Share Posted February 27, 2008 any offhanded chance of pulling out the cam when pulling off that seal cap? nah. Quote Link to comment Share on other sites More sharing options...
aircraft engineer Posted February 28, 2008 Author Share Posted February 28, 2008 OK - remember noids always come with a friend (it's a "pair-a-noids") :-p I thought the whole cam was moving and I didn't want to pull it out of the head so I just reseated it. The new seal was sure "solid" :cool: The WORST thing that could happen is that I have to go back in and replace the o-ring (that I should have done first anyway) Quote Link to comment Share on other sites More sharing options...
