Stock 2004 WRX 181,000 miles on EJ20T engine with no mods. Problem started with misfire code in cylinder 2. Compression test showed cylinder 2 at 50psi with all other cylinders testing at normal compression. Leak down test revealed exhaust leak on cylinder 2. Engine removed and broken down. Cylinder 2 found to have exhaust valve and valve seat on cylinder head burned.
Subaru service center recommends replacing left head assembly with new valves and seals. Estimate for repair is $3,045. with additional parts possibly needed. Dealer quoted $4600. - $4800. for 84k replacement engine as another option. I'm about as green as can be when it comes to auto repairs. This is my husband's car and he's flat out busy between work, Guard duty and getting his Masters degree. I'm trying to take the pressure of him by doing research and dealing with the service center myself. Question - Which of the two options would you choose? Are the quotes reasonable, or should I get a second opinion?
