The flame trap was not 100% clean-it had some "sludge" on it--all the holes were well open--the previous 2 owners (I am the 3rd owner)-kept the car well maintained-(They both kept meticulous records which I have now). The person I bought it from had it for 5 years-he was actually a "fanatic" (maybe even eccentric?) about fixing it up--replaced things that weren't broken--he just felt it had been long enough and certain things should be replaced--like the water pump-radiator--alternator-entire front suspension- changed the timing belt twice in 5 years--etc--he kept ALL his records--which I went over--the Volvo dealership knew him well--I saw personally over $18,000 in receipts of maintenance, repairs from his local Volvo dealership- (most "repairs and replacements" he did were NOT from being "broken"--he just did them--he gots lotta $$$$--said it was his "hobby"--buy a used brick--drive it for 5 years while basically restoring it-sell it at a loss--but he did get to drive it those 5 years---) his motto seemed to be --"If it ain't broke--replace it anyway". Oh-we have had it about 8 months now-I installed IPd's anti-sway bars--overload rear springs, and the 2 top "chassis-tower" braces--I am also looking for the "tower to tower" brace--(used)--(Our brick is a 240 wagon)-Bilstein HD rear shocks--the previous owner also put in new front struts about 2 years ago-along with the entire front suspenison being re-done. He even had the rear hatch removed--completely rewired and new tail gate shocks. (Ain't it fun to "brag" a little? Heh!) OK-the Amsoil--$5.70 a quart is good--I'll take 5 quarts 10-30, -and a filter! Thanks.
