Could easily be one thing of many or the entire pwob.. I don't know where the foul smell would work in though.. Burning oil usually isn't all that malodorous.. Is the plume really gray or more white? What you are really trying to watch out for is fixing one problem in the head when it's a couple of problems that are better seen too all at once (budget wise) and cracked seals might indicate that indeed - your head is (or was) running a little hotter than normal.. I still think there is something somehow amiss with the main head gasket myself given you are also losing cooling fluid according to your report - perhaps in addition to the oil seals.. The next question being how often do you have to top up the oil?.. If you really want to check properly - ask your mechanic to pull the thermostat, leave the cap off the reservoir bottle, then do a proper high pressure leak down test through the spark plug holes on a cold engine - then on a hot engine.. Make sure you are there when it's done.. If you are losing gasket contact - you will get air bubbles in the coolant - if it is the seals - they will foam.. If it's both - then you want to look a little deeper.. It may be that before you had to drop coolant additive in - the engine overheated, cooked the seals, the gasket or even slightly warped the head.. Almost endless problems best solved by shipping your car over to Nova Scotia Canada for sale cheap to good home with a great engine and crappy shell/interior.. :) .. (just kidding).. Look, as I'm not even in the same time zone as your beast - I would go with the wrench meister if you really trust the shop and after having sprung for the leak down test at this point.. -- J Dexter - webmaster - http://www.dexterdyne.org/ all tunes - no cookies no subscription no weather no ads no news no phone in - RealAudio 8+ Required - all the Time Radio Free Dexterdyne Top Tune o'be-do-da-day Tractors - Setting the Woods on Fire http://www.dexterdyne.org/888/085.RAM
