Replying to: xwesx (Jun 13, 2009 7:59 pm) Can I steam clean the engine and look for oil sepage? Also, do I need that cover on the bottom of the car? During an oil change years ago someone cut a hole in it. Over time it started breaking apart. |

Replying to: oldladydriver (Jun 15, 2009 4:12 pm) I wonder if there are any tech service bullentins about this problem from Subaru. I would be looking directly at the knock sensor and related computer circuits involved. Also, the service tech needs to take a ride with you driving the car so you can recreate the problem for him since he can not make it happen. That would be my next recommendation. |

I hope that to be the case, then you could very well get away with changing the oil brand and oil filter over a little time. Don't forget the old Marvel Mystery oil. Hold off on that thought though until you see what Lucas does. I have pulled Marvel out a few times in the past before doing a tear down. It has bailed me out as well when I least expected it. Sure beats a tear down any day. Will try to review your message history. You have one of the fun codes to resolve. |

Replying to: phil2000 (Jun 15, 2009 7:56 pm) Now, looking at your compression readings.... there may be your misfire answer. 1-220, 2-235, 3-195, 4-220. I have re-arranged, assuming firing order 1-3-2-4. Everyone else, pay attention here. One of the things I hate about OBD II! Old days, I would have no problems with this engine, but OBD II does and so does Uncle Sam. Here is why. Re-arrange to 1-200, 3-195, 2-235, 4-220. Here is most likely the cause for misfire code on this engine: look closely at the readings. You will see two lower reading cylinders followed by two higher readings. Those two higher reading cylinders will produce more power than the two lower reading cylinders which will eventually be picked up by the computer as a misfire code on 1 and/or 3 because those are the lower compression/lesser power output cylinders. Add any other small variable on an occasional basis from poor re machining work from valve job, you are screwed with a code. There goes the sticking valve hope.....your previous posts shot that thought down somewhat. Okay.... patience is cheaper than replacing the car. Time and observance may pay off in the long run still. It has served well in the past on high mileage units around here. So let's use that tool. Wes, seems to know it well also. I see you have dealt with cats, O2's and antifreeze. What about oil loss. Is any burning? The higher mileage Subs here, 240K seem to leak it out the back end from the oil gallery cover, and 'O" rings. I still replace crank shaft seals and clutches while back there also. Even with synthetic oil, they are very tight on next to no oil usage. I hope the same for yours If Lucas improves things, oil loss is next to nil, I would consider a synthetic oil with no additives and hopefully that will take of any strange variables out there adding to the unbalanced compression readings and reduce that misfire code problem. Intake Manifold gaskets....little late to mention it, but were the surfaces flat and square checked by a machinist. Takes very little to cause an air leak and a misfire code there as well. But that would not be an occasional thing. Keep that thought under your hat. Time to let this stuff churn in the old brain for a while and read some more of your posts later.

I have a 2006 Tribeca. While driving at about 70 MPH yesterday, my front seat passenger (who has some significant dementia) grabbed the shift lever. Fortunately he only pushed it to the left side, putting the transmission into Sport mode, so nothing bad happened. My question is, what if he had managed to push the lever forward? Would some sort of damage occur?

Replying to: robotb9 (Jun 16, 2009 11:51 am) Now for the transmission. This particular car I know little about, but in general it is not a very good idea to shift any transmission while it is under a full load. Even in an auto, I back off the load before I force a downshift on an auto. Yes, I know it has clutches inside it. But those do not work like most people think they do! They work completely opposite of a manual setup. Bottom line is you are forcing parts to change position while under a load and that can get nasty at times especially if you decide to put it in "R" for Race as the old joke goes then wondering why it blew all apart. Again, for safety sake, that person needs to be in the back seat!

Replying to: girlcarbuilder (Jun 16, 2009 2:00 pm) I am hoping for an answer to the question about the transmission itself: what sort of damage could have occurred? |

Replying to: girlcarbuilder (Jun 14, 2009 3:28 pm) I did find both A/C charging valves were bad, (an engineer friend found these with less than a 5 minute glance under the hood). One of these is located right near the air intake for the cabin. This was after the heater box was replaced and I was still having problems. Several people/mechanics have suggested that there is a coolant leak (none from Subaru, however). So, you are dead on. No one has mentioned the evap core. I'll have to look into that as well. Unfortunately, I have no way to check for heater core leak, as it is inside the heater box and relatively inaccessible. Then, there is the other "known" Subaru problem of some oil on a gasket that can last for 15 months+. So, yes, I've definitely been breathing the refrigerant, and it is not nice stuff to be breathing. I've also been breathing the oil blend that was on this gasket which also causes a window film. And then again, there could be other items that I am breathing and these in combination do who knows what to me. I'm just hoping that I don't end up with the multiple chemical sensitivity problems that you have and that once Subaru agrees to replace my Forester with another that I will be home free with no permanent damage. At this point, I can't be sure of that however. Sorry to hear of your health issues as well. I have some friends who have similar problems, some of which are very debilitating. Thanks for your comments.

Replying to: smudgejet (Jun 12, 2009 5:27 am) That is why I don't think it is a typical problem and am surprised Subaru won't just do the right thing and swap this car out for another like vehicle. I suppose the lawyers are worried about admitting anything is wrong. |

Replying to: sgloon (Jun 16, 2009 5:46 pm) Can't complain about ours, it's been great. New car smell has subsided and my wife is thrilled overall. Funny thing is my 1998 model has a far worse smell than the 2009, in fact I used to call it "new car stench". |
