Check the screen on the oil pump pickup - make sure it is clean.
If there is much sludge, tear it down completely, clean everything, measure everything.
Replace items as per necessary.
Even if it has sludge, the major components may all be fine.
Phasers, guides, tensioners, chains probably should all be replaced.
Take a close look and the exhaust and intake manifolds for corrosion, pitting and stud conditions.

cam phasers replacement on the 2v's is crucial.

I wouldn't do all that unnecessary work, unless there was a reason for it. With those miles especially. Ask the guy about his oil maintenance regimen. What was used, who changed it, how often. Gaskets won't ever go bad unless there was problem before hand. Timing components, with that one ? You have a long time before that may be issue. I'm at 300,000 plus and haven't had a issue yet.

Trust me, ask about the oil and maintenance. Look it over well. Check the exhaust studs, inspect the intake manifold and look into the block cavity for signs of water staining. Since the manifold has to come off, replace the O-rings on the water pump stem for the heater core hard line.

That's it, I wouldn't tear into it any further.

Great find btw, specially if maintenance was handled.

Timing chain tensioner was bad and as long as I was there I replaced the chains as well as tensioners. I probably replaced several thing on the engine that were fine. However it will never be easier than while the engine is on the stand and at best the parts were 15 years old.

Drop the pan and check the oil pump screen - be easy with the engine out.
Clean screen will insure good oil pressure.

It looked good and because I got a crazy good deal on a new Melling oil pump I changed the pump as well.

Lookin good.

Enjoy the almost new engine.
