Re: 130k & 258 kaput :(
The timing chain normally lasts the engine's life, but you can just
remove the distributor cap and see if the rotor is turning to verify
it. The rotor also should just be past #1 post when #1 piston is at
firing TDC or opposite if on exhaust TDC. I have seen an 89 with an
exploded plastic timing gear before and no other damage happened.
That would tell you if you have to open the front or bottom at least.
Long term knock that got worse, my guess is a rod bearing.

A simple compression check will tell you if a piston has holed out.
And while your there check the plugs. A cracked plug can also cause
problems.
Lifting the valve cover and looking will tell you if a lifter has died
and cranking it while looking will tell you if something else is bad.
(crank, not start, pull the coil feed)
Shaking could be a ignition and/or timing issue too.
Like others have said, timing chain slip is possible I don't remember
if the 89 has steel or plastic teeth. IIRC they are steel.
A head gasket blowing would have filled up the oil with coolant or the
coolant with oil. Plus the usual white tailpipe smogcloud o doom.
Depending on your pain threshold a short block might be a good idea.
