Did you do a compression or leak down test?
Not yet.Did you do a compression or leak down test?
Can't really add a ton of tech value here Matt, but those pictures are really nice! do you think that gunk in cylinders 1 and 6 is relatively new? Or really old? It's odd that you don't see matching gunk on the spark plugs... which might imply that the gunk's been in there a while, longer than those spark plugs?
That part number looks familiar.Safari recommends NGK BCPR7ES-11, which I understand are a Saab turbo application.
That's a good point, when ATP tears it down hopefully they can identify whether the compressor is missing any pieces. It seemed to me the compressor was ok but it was the turbine side that was worn, so I don't expect pieces of the turbo to be in the engine. But can check again.That part number looks familiar.
Are there bits of the turbo impeller on the top of #1 and #6 pistons? I'd want to be sure all of that was cleaned out before running the engine again.
