Listed as Non-Technical as in non-Speedster, but sorta technical. Maybe file it under Terminal Dumb-ass, or maybe just Snake Bit, . . . anywho,
A few careful observers will recall I asked a while back about oil filters that might leak. Like if you do not tighten right, or the gasket fails, or something. I was having some wetness on bottom side of the engine in my Mazda6 V6, and was looking for where a little bit of seep might be coming from. Was putting a small drip on the garage floor now and then. No biggie, as I have had cars that dripped oil much worse in years past. But this car had been dry as bone for 65K and so now what?? And I 1st noticed just after I changed the oil filter. Well, I put up w/ it for a while, looked around at other spots, could not really tell where was the source. Thought maybe the drain plug, as gasket there never renewed, and was getting stiff. Put in a new one at the next change. Bottom of engine still getting wet, small drip now and then, sorta smells a bit when engine hot, drips now once in a while on exhaust pipes in the area, so stinks. Still, not enough to even register on the dip stick. I thought: main crank front seal. Hmmm, that would not be fun. Ho-ho, little did I know. Rumbled on for while, now at 72K, still dripping, wet bottom. So I go to a local Mazda club tech night at one of the local good-guy dealers, and speak to mechanics that know the engine. They agree that likely is main crank seal, but not too bad to fix -- they charge $250. So I decide OK, I'll have them do it. -- Can you hear what's coming next?? I arrange to take the car in. Guy calls me to explain what he sees once they start to dig. PS This is a V6 FWD, so packed in pretty tight. Their assessment: oil coming from all four engine seals: main front crank, timing chain cover, oil pan and the fire-wall side valve cover. Was $250, now is $1400. Oh woe is me. Guy says he'll do just the main crank seal, but knows I'll be back soon complaining he did not fix it. And so, nicely positioned over the barrel, bottom side up, and with plenty of lubricant applied, I got screwed. In fairness, I have heard that this engine has rep for leaking oil from its seals. Also, I went to the shop and looked before they went whole hog, and I could see the fresh oil on the engine at these places.
PS: the oil filter, at around $3.50 or so, is dry as a bone. Anybody else here drive one of these?
