Bent Valves?????

[BlownAway]

I posted that my Balance Shaft Belt broke well at the same time my car stopped. When I changed the belt and put the timing belt back on I did a compression test and the needle never climbed to where it needed to be nor did it hold. I took the head off and I cant tell if they are bent or not. But on the # 3 piston the valves have alot of corossion and build up. Their are no marks on the pistoms that would lead me to believe they ever hit. Can someone tell me why their is build up and how to check if they are bent just enough to not hold compression

If you have the head off take it to a machine shop and they can check the valves.

If it is just the valves, and if it is they are bent very little because this will be the second time and the first was bad. All I have to replace is the valves right.

Their is a hard build up on the valves what is that from
