cookie Posted October 12, 2005 Share Posted October 12, 2005 That is the first time I have heard of a timing chain problem with the H6. This makes sense as that would easily affect all three cylinders, fairly rare on a chain engine. I'm glad they found it for you. Quote Link to comment Share on other sites More sharing options...
blitz Posted October 12, 2005 Share Posted October 12, 2005 All in all, the EZ-30 looks to have been a solid performer up to this point. No slapping or gasket issues. Quote Link to comment Share on other sites More sharing options...
mgiff3860 Posted October 13, 2005 Author Share Posted October 13, 2005 They found a bit of sludge when they pulled the cover and there was some speculation that this might have been the source of the problem. And yes I am deligent about my oil changes. BUT I was told to start changing the oil every 2k. Seems this was not the first one that had sludged up.

friendly_jacek Posted October 13, 2005 Share Posted October 13, 2005 What oil did you use and what intevals (miles AND months). This is the first time I'm hearing about sludge in subaru. Quote Link to comment Share on other sites More sharing options...
Gnuman Posted October 13, 2005 Share Posted October 13, 2005 They found a bit of sludge when they pulled the cover and there was some speculation that this might have been the source of the problem. And yes I am deligent about my oil changes. BUT I was told to start changing the oil every 2k. Seems this was not the first one that had sludged up. What the FSCK?!?!?! If the engine is sludging up at 2K (or even 3K) then there is a major problem with the design of that engine. This indicates that the engine is getting hot enough to boil the oil to sludge, or the filter is not holding the sediment from the engine (because it is producing too much?) then the root problem needs to be corrected. Telling the customer that he needs to change the oil more often is not a solution. Quote Link to comment Share on other sites More sharing options...
nipper Posted October 13, 2005 Share Posted October 13, 2005 Well i can also be from taking very short trips an not letting the car warm up. If that is the case you have to switch to hotter spark plugs and a differnt oil, prbbly synthetic. nipper Quote Link to comment Share on other sites More sharing options...
bulwnkl Posted October 13, 2005 Share Posted October 13, 2005 I'd like to hear more about the "sludge," too. Either way, what is the timing chain's tensioning mechanism in the EZ-30? Is it a hydraulic tensioner or spring-loaded? Quote Link to comment Share on other sites More sharing options...
cookie Posted October 13, 2005 Share Posted October 13, 2005 This is why some companies have gone to synthetics. In a number of modern engines the operating temp is hot enough to sludge them up. Most timing chain tensiors are hydraulic these days and sludge is a no no. If it were my car it would get synthetic oil and regular monitoring with oil analis for a while. I am not sure what conditions in Colorado might have to do with it, or if this will turn out to be a problem as with some Toyotas and Hondas. It sure sounds easy to fix.
