Hey guys this is my first time ever doing any type of form question so help me out. I recently bought a supposed to be 95 Subaru Legacy front wheel drive wagon. Prior to purchase it had the gaskets replaced timing belt spark plugs and wires and water pump. I discovered I had to pass emissions test to title and plate it. So I did the knock sensor Upstream O2 sensor and CV axles. Now for the last week progressively getting worse is a knocking sound from the engine almost like a piston slap when I first start the car and it's still cold. Once it starts to warm up the noise quiets down and within 5 minutes you can't even hear the engine running but it is noticeably loud when it's cold and first starts. Any ideas???? -
I recently bought a 2005 Impreza with the 2.5 and manual trans. The original motor broke the timing belt and ruined the heads and cracked the block. I bought another 2.5 out of a 2001 Outback with auto trans. The motor ran great in the 2001 before it was pulled. I had to put the intake from my 2005 2.5 on the 2001 2.5 plus the clutch, pressure plate, and flywheel. After putting the motor in my car and running it for a few hours it started making a pecking noise. I pulled that motor back out and already found a 2.2 with on 80,000 miles on it. The 2.2 ran great in the donor car before I pulled it. I pulled it out, changed the intake, and installed my clutch, pressure plate and flywheel and a new throw out bearing and the motor went straight into my car. After running it for about 30 min. it started pecking just like the first motor I bought. I pulled the motor back out and bought a new clutch, pressure plate and flywheel. The clutch disc had a lot of play in the collar that slide onto the trans shaft. I then put the motor back in the car and it still makes a pecking noise. ANY INFORMATION AND ADVISE WILL BE GREATLY APPRECIATED! It doesn't make since that both motors wan fine in the donor cars until i installed them in my car. PLEASE HELP!
