Hey guys,
To make a long story short, I just bought another subaru after a couple of years without one. Bought it a few weeks ago, and everything was fine during the test drive and the first week, no weird sounds or anything, except a loose exhaust heat sheild.
Since then it as developped a knocking sound, only audible when the engine is warm, in 1st & 2nd gear between 2k and 3k.. 1 time out of 10 it won't make it.
I can't replicate the sound in neutral, unless I go crazy with the throttle "bleeping"..
cold or warm idle sound fine except a few random miss. (40k miles on the sparkplugs.. )
A while back my 2003 impreza OBS developped a rod knock that sounded exaclty like this, but was audible at idle and when reving the engine at 3k and bleeping the throttle.
Any ideas how to know for sure its not a rod knock?
