Default Engine experts please help troubleshoot
Hi,
I am helping a friend of mine with an engine failure. The engine is a 351 windsor normal stroke with Edelbrock heads. approx. 3000 miles on a fresh rebuild. The pistons are Wiseco forged. As you can see, a chunk broke off of #1 piston. As far as we can tell the engine did not ingest an object causing this. In the circled areas you will note that the aluminum has been eroded away. The last photo is of another piston from this engine. It also has some aluminum eroded, though not so much as to cause a failure yet.
Question: What do you think is causing the erosion??
