Springs fixed. Got van back. Oil light on and van runs with noise. What is the problem?

What is your question?

Van ran fine before having springs replaced on front. Oil light on, a pecking/knock in motor, and after it warms up it will die. But once it idles there is no sound. Whats wrong?

What makes this problem better or worse?

On starting. At idle no noise.

How long has your 2009 Kia Sedona had this problem?

Just since springs replaced
