Do my pistons look dented or scuffed?

[Spoolin4Ever]

Had a timing belt incident a while back, car been sitting forever since then. I finally pulled the head. The car had either no compression, or very little (it's been so long I forget). Before I pulled the head, when the engine was running, I heard a sound that sounded like the pistons hitting the valves.

Yup looks like you bent some intake valves. Pistons look fine though.

Pistons look okay,except the need a thorough cleaning. As much as it sucks that the valves probably hit, it was time to remove the head and get it all clean again. Blessing in disguise maybe...

Loss of compression on t-belt issues is almost always tweaked valves. If you take them out and put them in a drill chuck you can spin them to see if they're straight. My guess is that you find they wobble when doing this.

Debur the pistons where they kissed so you don't have any extra hot spots! A little emery or a dremel but keep the dust out of the rings so tape off the pistons before you do any touch ups on them, if you do. They don't appear hurt tho.
