SuperchargedRS Posted March 7, 2008 Share Posted March 7, 2008 Well I took a turn around left hand banked turn in my 90' loyale and looked behind me and there was SMOKE?!!! no loss in oil pres, temp normal, it smoked for a few seconds and stopped, no power loss, nothing. NOW the subie does leak oil (as you can see form my other threads) from the drivers side cam area, could the oil of just leaked on the hot exhaust pipe during the turn and flashed? or is this something else?? Thanks, S *When I bought the car is compression tested just fine 165ish on all 4, no oil in coolant, quite running engine, only problem I have noticed is the oil leak (which I will fix soon) and the annunciator panel "check engine" and "oil" lights are out (which I will fix as well).

GeneralDisorder Posted March 7, 2008 Share Posted March 7, 2008 It's your breather tube system. This is a known issue that was addressed with a service bulletin in the early 90's - all the SPFI systems were retro-fitted with a smaller tube into the intake boot where the breather hoses T off. If you do a search for stuff related to SPFI, and smoking you'll find threads with pics detailing the differences. There's a kit availible at the dealer - it doesn't entirely eliminate the problem but it reduces it a lot. GD Quote Link to comment Share on other sites More sharing options...
SuperchargedRS Posted March 7, 2008 Author Share Posted March 7, 2008 So I am getting oil splashing up my breather and getting induced in my induction system? Does this cause damage to the vehicle? Best fix to do? Thanks Quote Link to comment Share on other sites More sharing options...
misledxcracker Posted March 7, 2008 Share Posted March 7, 2008 Replace the PCV routing if it's the old crappy system. Make sure to not forget the tiny plug for the old intake boot hose! My '86 had this joyous smoking issue (smoked more than I did ) and replacing the PCV routing took all the smoke away. Quote Link to comment Share on other sites More sharing options...
SuperchargedRS Posted March 7, 2008 Author Share Posted March 7, 2008 Is this a dealer only part? how much$? Thanks again Quote Link to comment Share on other sites More sharing options...
misledxcracker Posted March 7, 2008 Share Posted March 7, 2008 You can find them at the junkyard. OEM, it ain't cheap, dont ask me why Near $42 if I recall. For tees and hoses. But eh, I love my baby (I see you have a '90 Loyale.... it has the updated PCV system already. Check your PCV valve?) Quote Link to comment Share on other sites More sharing options...
SuperchargedRS Posted March 7, 2008 Author Share Posted March 7, 2008 Would a 89' have the updated system as well? Quote Link to comment Share on other sites More sharing options...
azsubaru Posted March 7, 2008 Share Posted March 7, 2008 I thought the breather fix was only for smoking on long RIGHT hand turns...? so Cracker may be on the mark with checking the PCV valve. Anyhow, here's a thread that goes through the breather retrofit, even has pictures and the part number of the kit. I had to do this on my 91 Loyale, so your 90 will probably need it, too. http://www.ultimatesubaru.org/forum/showthread.php?t=16162 You can make your own with heater hose and a few fittings, though.

Yea this was on a long LEFT turn, so is it the above mentioned PCV problem? Thanks guys! Quote Link to comment Share on other sites More sharing options...
SuperchargedRS Posted March 11, 2008 Author Share Posted March 11, 2008 Well I looked and I HAVE THE UPDATED SYSTEM ALREADY??? it has the blue "T" connector and everything wtf???? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 11, 2008 Share Posted March 11, 2008 Change/clean the PCV valve, all the hoses, and the valve cover ports. GD Quote Link to comment Share on other sites More sharing options...
