GT Legacy 93 - Acceleration, Pulley & Turbo

[sandoz]

Hey All,

 

Any tips would be helpful. Cheers.

 

I've had a 93 GT Legacy Wagon for about a year now.

Engine is an EJ20, turbo, manual trans, fulltime 4wd.

Has 120000km (75000 miles) on the clock.

 

Recently replaced rocker cover gaskets, added Promar oil to try and quieten tappets (didn't work). Been running on 91 and 96 octane mix.

 

My concerns are:

 

1. The car seems to have developed an issue when accelerating. It drives fine but when when I hit the gas it seems to miss or buck a little before increasing speed. It only does this when driving, doesn't miss when stationary.

I tested the clutch and it seems ok. Tested by pushing shifter into 3rd and depressing the clutch. It slips into 3rd little after pushing two thirds on the clutch.

I'm guessing something else along the drivetrain is the cause but I'm not sure where to start. What could cause such a symptom? 4wd mechanism? The diff? Could it be something with the engine if it onlly does it when driving?

 

2. Recently I noticed the pulley on the end of the crank (i think it's the crank, see photo) wobbles slightly. A subaru mechanic said not to worry about it, but I'm not sure. Pullies shouldn't wobble now should they?

 

3. There's a radiator type cap on the intercooler but I'm not sure what's supposed to go in there and how often I should check / change it. Any ideas?

 

Thanks for reading.

the radiator tyoe cap on the intercooler is exactly that. a radiator cap. you have a water to air intercooler. it should use regular coolant just like the rest of the cooling system...
