discojon Posted March 14, 2016 Share Posted March 14, 2016 In the process of trying to track down a boost leak by doing a boost leak test through the Bypass valve signal line, intake plugged, I managed to blow something, i'm guessing a half moon seal or cam seal?, loose. Steady dripping of oil coming from passenger side timing cover. Pulled cover and oil is evident on that side only. Can't see the origin of the oil. It must be coming from behind the exhaust camshaft pulley. Before I pull the timing belt and pulleys, is there anything else to check? No leaks from valve covers.

Fairly certain I pressurized the crank and blew the cam seal out... Link to comment Share on other sites More sharing options...
FJuan Posted March 14, 2016 Share Posted March 14, 2016 I'm in the same boat with you, I discovered the same thing yesterday while fixing my uppipe. Pulled the cover off and oil all on the bottom on the passenger side. So what I did, since I saw oil on the valve cover next to it, I spayed brake cleaner all over the clean up all the oil. I'm gonna check in a few days to get a better idea where the oil is leaking. I'm really hopping it's not the exhaust cam gear oil seal, that's a bitch of a job to do. My wife's balls are delicious.

discojon Posted March 14, 2016 Author Share Posted March 14, 2016 Well I'm pretty sure I literally blew mine out. Its an active leak, not a gusher but bad enough I can't drive it without making a smokescreen. Looks like I'm pulling exhaust cam gear tonight Sent from my SAMSUNG-SM-N910A using Tapatalk Link to comment Share on other sites More sharing options...

Mine is a slow leak to were it drips down onto the exhaust manifold heat shield and I can smell it once the car is up to normal temps. I have a bad feeling that I may have to do the same here shortly. Let me know what you find. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
discojon Posted March 15, 2016 Author Share Posted March 15, 2016 Just as suspected. Blew cam seal out. Now if I can just get it back in time..... http://uploads.tapatalk-cdn.com/20160315/d438b7a7d1edefd4ece4a716a7ef41f2.jpg Link to comment Share on other sites More sharing options...
FJuan Posted March 15, 2016 Share Posted March 15, 2016 Damn, now that means I have to check mine now. You're putting in a new seal, right? My wife's balls are delicious. Link to comment Share on other sites More sharing options...
discojon Posted March 15, 2016 Author Share Posted March 15, 2016 I'll see if i have one laying around. This one looks fine. It only has about 60k on it. I am going to change the timing belt though. Link to comment Share on other sites More sharing options...
discojon Posted March 15, 2016 Author Share Posted March 15, 2016 That fixed it. Timing by yourself is a bitch. Link to comment Share on other sites More sharing options...
discojon Posted March 15, 2016 Author Share Posted March 15, 2016 Now that I'm cleaned up, The xam seal simply popped out. Presumably because the crank case pressurized through the pcv. It was the weakest link. Pressed it back in with a 26mm socket and smeared a bit of three bond on there for good measure. So I did a timing belt, one cam sprocket, and seal all in about 5 hours.

Gex Posted March 17, 2016 Share Posted March 17, 2016 Not bad! What psi were you running the tester at? Link to comment Share on other sites More sharing options...
discojon Posted March 17, 2016 Author Share Posted March 17, 2016 Not bad! What psi were you running the tester at? I typically set the regulator to 7 psi but this time I left it on 20 ish. Link to comment Share on other sites More sharing options...
