So, I have a very nice running 2.0, I went through it last spring and its been bulletproof and reliable.
No trouble at all, but lately I've noticed a little more valve clatter. Oil change and valve adjust and its fixed.
2 weeks later, a little valve clatter...valve adjust and..hmm..exhaust on #2 is suspciaously loose. Well, it happens, adjust and on my way.
Another couple weeks and tik*tik*tik...WTF? I go straight to #2 and there it is, a loose .008".
Adjust and I can see that particular adjuster screw is in further than the others.
Not good, but from my experience / understanding the valve seat gets hammered INTO the head and makes for tight valves until it drops out. Engine has about 4000miles, and no other symptoms- no signs of cam wear, haven't pulled the lifter yet but #4 has good/consistant clearance. Adjust screws appear good, no wear.
What do I do?
