Hi Mr. Starkie!

Sure happy we're all havin' some moar pumpkin pie holidays! I make an excellent turkey gravy (browned flour, turkey drippings, and buttermilk!), stuffing using stale ultra sour dough bread and stuff, and them frenched green beans in the cream oif mushroom soup! I like making cream of mushroom from scratch.

2nd the dipstick o-ring. These are always brittle and shrunken.

2nd to the excess crankcase pressure from a clogged PCV / oil breather box (drain back hole can clog).

Also, like Uncle Phil Machine Man says with the compression ring blow by. May want to perform a compression test on the engine with fully charged battery and all spark plugs out with wide open throttle. Have a scope to check the cylinder bores?

If the engine ran mineral oil, yet suffered from no oil changes to no oil changes to no oil changes, change the oil. Use a good filter and use a cheapo synthetic as synthetic 10W30 or 40 does great at cleaning deposits. The piston rings may be full of carbon deposits and do not float freely, causing hastening compression blow by.

Also, you may want to use your trusty and not rusty digital electric multimeter to test engine sensors like oxygen sensor, coolant temp sensor, AMM / MAF, knock sensor, and other sensors. Verify a good ground between the alternator and engine as this cable from factory is sort of frail after thirty-five or so years. Poor grounds make for weak spark. Also, failed sensor or wire harness connectors between a sensor and the ECU can make for poor (usually rich) running.

Hope that helps.
