no codes. I had the intercooler and all lines off while replacing the blasted PCV because it is a friken basterd to get at so I hope I would have noticed a line not attached during reassembly. it stopped the surge for a day or two once the new one was on, but went right back to low idle and surging. could a ram air cause the surge? suspect the turbo is the culprit on the oil consumption, just wanted some other opinionsmany many turbo cars come by my way with stuck rings, busted ring lands, oil being shot out the turbo. Also might have to do a thorough search for a small vacuum leak causing the surging and disrupting your PCV system. DO you have codes like P0171? Fuel System lean bank 1?
The 04 STI timing belt change interval is 105k miles, but I would do it far before then just for safety's sake.Pretty sure the Owners manual to my 2009 WRX says to replace the timing belt every 60,000 miles.
a quart atleast every 1000 miles or so. pretty much once a month or more!The 04 STI timing belt change interval is 105k miles, but I would do it far before then just for safety's sake.
Kat - definitely pop the intercooler off and see if oil dumps out of it. Also pull your spark plugs and see if they look ashy or if one in particular does. If none of the above, the turbo could be dumping it out the exhaust side.
How much oil (qts) would you say you loose in 100miles?
