This was a car in the junkyard on Saturday. .hopefully mine is not as bad. It was dark and it was a good place to stop when I finally got the alternator and manifold off. Thats not soil..thats buildup from infrequent oil changes and just general age. This breatherbox needs to be replaced some time in a Volvos life. At 256k mine had been showing symptoms of clogging..pics of mine tomorrow. Oh yes the alternator doesnt usually have to come off..just that mine has been dying at an accelerated rate as of friday..saturday..the signs were more real..and last night..well poof..
