I just found this quote from the ad when I bought the car a few years ago:

"The car has a modified head and a modified ECU to allow use of the Euro wastegate spring."

What do you think they did? Maybe I should contact the previous owner.

 

Isn't Google amazing? From the previous previous owner's ad:

"Modifications include,,, port matched intake and exhaust, multiangle angle valve grind, chipped ECU with euro wastegate spring"

Doesn't mention anything about the cam but I am intrigued by "chipped ECU" now.

 

I disassembled the turbo, manifold, down pipe and waste gate over the weekend. It put up a bit of a fight but nothing a bit of heat and an impact gun couldn't handle.

The manifold is cracked. Need to decide whether to repair it or install the later Audi "fix" manifold.

There is a little play in the turbo bearings so I think I should have it rebuilt. Any recommendations for a rebuilder?

Should I rebuild the waste gate too? I've been told they wear over time and bleed off boost.

 

Progress is slow. Please stop ordering wheels so I can work on this car more LOL. Oh, I meant "Please order more wheels so I can afford parts for this car".

Today is brought to you by the letter Oil Pump.

and Cleaning pistons. I used gasoline and a soft wire brush. A lot of grease from my elbows helped too.

I went through my parts stash over the weekend. It's amazing what I have. Am I missing anything though?

So I'm ready to start putting this engine back together but I'm still not 100% convinced my refurbished head is correct for the WX engine. Are the 38mm intake valves and slightly smaller cam lobes stock for the WX?

Of course I will need a head gasket and apparently new head bolts for this job. I assume these should all be OE right? Any suggestions where to buy (USA preferably). I'll obviously need a few other seals and gaskets but I might have them in my parts stash already. If you noticed anything that wasn't pictured above let me know.

Time to turn the corner on this project.

 

Oops, sorry. I forgot to post these two pictures. First one shows the oil and coolant passages on both heads, To me they seem identical.

I'm a bit concerned about how some of the oil and coolant passages were seemingly blocked (red) or partially blocked (yellow) by the old head gasket. Is this normal?

It looks like my refurbished head has hydraulic valves after all so it was decided to refurbish the head that came off. To that end I ripped into it. Not sure it's going to work out though.

Can it be salvaged?
