Seller says engine has valve problems on right side. Buy or don't buy?

I'm guessing a cam drive chain jumped a tooth or 2 & the pistons kissed the valves enough to bend them enough to prevent them from sealing. Loss of compression in the cylinders due to the leaking can easily be heard with engine running & engine still runs with big power loss. If seller would make video with sound of engine running it would help evaluate extent of damage.

If you are mechanical and don't mind fiddling with it or parting it out if it looks like too much just go for it. One caveat is that the car must be in great shape other than the engine problem, parts that are worn don't sell at all and sinking money into fixing the engine will eat up the budget to fix everything else if anything is broken or in bad shape. Any car that age will need some things replaced no matter who owned it but clean cars are the only ones with any value any more.

Thank you for this answer. I am of the same opinion like you. Why do you think the cam drive chain jumped a tooth, broken tensioner?
