I bought a used engine for cheap. The seller said that a coolant seal went, so he drained it and it sat for a while.
I have the engine sitting on my engine stand now.
Would it be worthwhile doing a compression test on it, to gain more information? Is it worth the risk of doing more damage if something is jammed or corroded?
Or should I just take it apart and inspect everything visually?

Thanks

If it's known as blown, removed from the car, and sitting on a stand, then I wouldn't bother trying to do a compression test...

Just tear into it and see what you're working with.

I'd just take it apart at that point, if it sat with bad coolant seal, the metal seals may be rusted in place and may jam into the housing ect

Yep. I've been through a few motors that had bad coolant seals that sat for a long time and all the seals were rusted into the rotor. Was a CHORE to get them out, at least 1 time I had to just throw out the rotor.

Compression test won't give you anything here. When a motor is open all secrets are revealed.

You should trademark that last line, Dale

It's at least "signature worthy", for sure.
