Looking for a potential new daily and I have found a Subaru for sale, 3L 6 cylinder, 2005.
Vendor says "Engine has done around 1500 miles since the complete rebuild and seems to still be burning oil.
It may well be that putting a few more thousand miles on the engine beds the rings in and reduces the oil consumption but it fouled the plug on cylinder 6 while my wife was driving on the motorway,the EML came on showing misfire on cylinder 6 and she is now refusing to drive the car anymore.
Hence it is up for sale.
Now the spark plug has been cleaned up the car again Runs and drives smoothly. Mechanic performed a leak down test showing that compression on all cylinders is good.
When the engine was rebuilt should have had the bores honed at a machine shop to facilitate the bedding in of the fresh piston rings, this step was neglected and as such there was a question as to how long or even if the rings will bed in sufficiently to reduce the oil consumption. My mechanic says it's just a case of putting enough miles on the engine and until the rings are fully bedded in.This may involve cleaning the spark plugs a few times if they continue to become dirty due to fouling. Currently it's only one cylinder number six which has fouled the plug."
It sounds like the car is very well maintained mechanically other than this issue, but bodywork far from ideal.
Any ideas of how much honing might cost, and whether it will be needed or whether it will bed in naturally? What sort of discount would you want for this issue, or would you walk away?
