OK here is an update: 1. Cleaned out the air intake, cleaned out the PCV hoses and Ts, found a crack in one, replaced it. 2. Changed PCV valve (it was nasty) 3. Changed out the autolite plugs to new NGKs ($2.88 per),gapped at .40. 4, New fuel filter 5. New air cleaner 6. Ran a tank of Chevron premium, added sone techron. Took it to IM today with a 1/8 tank left, dumped in 3 bottles of Heat, jumped up and down on bumper to mix, revved engin, drove it in and blew Hydros of 236 at 832 rpm....limit is 750 so the little freak passed with flying colours...

Hey im in anchorage...i had run it over to AAA subaru which has a good or bad rep depending on who you talk to.. Now if we retard the timing, wont that cause more emissions? So I should eat the valve pings for now and retard after IM right? The oil leak is mostly under the oil pan...no drips in the driveway Gonna try IMing on Sat with the heat trick...now how about that rough idle?

Ran it for 50 miles, still seems to be idling rough....also now thats its properly timed seems to be "diesleing" or knocking at some speeds

OK gonna take it for a highway trip tonight, then drive it tomorrow and see what the carbons are....

Got a summer waiver for it so I can drive till it passes... The air filter looked pretty clean...worth it to change anyway The mechanic told me the o2 sensor is OK Should I run it hard on premium?

Just got a beater subaru again after oh, I dont know, 30 years. Its a 92 Loyale, 170K. Im impressed by the power this and the power that, hell of a lot nicer to drive (although not as fast)than my last beater, an 85 Prelude. The issue is two fold: Mechanic tells me that the valve covers are leaking, oil pan gaskets, oil pump gaskets etc, although you dont see much drip. Think its worht it to change this stuff out over the Alaska summer.?? Second issue is that it fails hydrocarbon test at idle, and it does idle a bit rough. First time tested 1080 (750 pass), second time 1230. Took it over to a Sub analyst who cleaned injector, retimed it (it was way off), checked this valve and that valve and this module and that module. Plugs and wires are fairly new as is cap. Coil is old.EGR is good. Oxy snesor works. Oil change is fresh. Seems to idle better, but he thinks cat is shot. Reason being is that he cant get it to consistely blow hydrocarbon... it ranges sometimes in the 500s, sometimes 1200s. Now this car sat in the winter without running with no gas from about October 04 to last week, I have it filled with fresh gas and seafoam. It runs like a top and has nice pickup, although there is a bit of dieseling at certain rpms if the gas isnt punched hard It also shows a bit of oil in the "intake?" I just need this to pass Emissions....mechanic thinks sooner or later Ill get lucky and it will be blowing light hydros on one of the tests (no pass, no pay) which I can do often...what about running it hard until the tank is empty, filling with premium and octane booster and some of that "Guaranteed to Pass" chemical...think that may work? Any other suggestions?
