hotdog Posted July 26, 2006 Share Posted July 26, 2006 Hey everyone, I have a question and not really up to par on the subarus. I have a 1990 loyale 1.8 auto, lately has been running rough, smokes really bad when started, blue smoke, loosing a lot of oil, spark knocks really bad on acceleration, has no power (though i am not expecting a whole lot) but it is really bad. When i bought the car back in january I did all the routine maintenance items, spark plugs, wires, distributor cap and rotor, replaced all vacuum lines and hoses, had to replace those i guess called thermo vacuum switches for the egr, evap system etc for being broken. fuel filter, air filter, as well. did the whole top engine cleaning and seafoam procedure and car was running awesome. past couple months has not been driven as much, occasionally, and lately these symptoms started showing up. so back to my intentional question is, would it be smart to do a rebuild on this motor now, or buy one of those japanese long blocks and put that in, or buy another newer motor or any other good or recommended engine swap? or any ideas on what could be wrong now for a somwhat easier fix? check engine light is on as well code 35 for evap purge valve, it is a throttle body injected engine. Has 132,000 miles and from what i have read it is supposedly pretty young still for subaru standards, so that is why i am asking if it should be needing a rebuild or motor. I am going to do a compression test soon, and all that, just figured i would see some opinions from you guys. thanks. sorry for the long question!

MilesFox Posted July 26, 2006 Share Posted July 26, 2006 check the pcv ststem for clogged lines and such as this can cause the intake to suck oil. make sure the green test connectors on the driver side firewall is disconnected. these are connected when setting the initial timing at the disty, but are unplugged for normal operation Quote Link to comment Share on other sites More sharing options...
NorthWet Posted July 26, 2006 Share Posted July 26, 2006 check the pcv ststem for clogged lines and such as this can cause the intake to suck oil... My vote, too. If the symptoms are worse while going around right hand turns/sweepers, even more indicative of PCV issues. Slightest amount of oil getting ingested will make the SPFI motor ping loudly.

Cougar Posted July 26, 2006 Share Posted July 26, 2006 I agree with the others about the PCV system and would try changing the valve with a new OEM one. This is a fairly common problem. You need to do a compression test to evaluate the condition of the engine and that will tell you what will need to be done. If the knocking doesn't clear up you might have a timing problem. If you check the timing be sure to follow the proceedure to check it. The problem may also be due the grade of gas you are using. Especially if you changed brands when this started to happen. Start with the simple check items first and move up from there if you have to. Quote Link to comment Share on other sites More sharing options...
hotdog Posted July 31, 2006 Author Share Posted July 31, 2006 thanks for the input, i just checked pcv system, I had replaced all the lines when i got the vehicle, but I found oil is present in the line to the pcv valve, i rmeoved the valve and it moves freely inside, and checked with it in the intake for vacuum and it has vacuum and when plugged off i can hear the valve shut. maybe i should just replace it anyways but still have to perform compression test. any suggestions for a good engine swap? what engine? just looking as an upgrade type of thing.
