Jeep fault
I have owned my jeep since 1980 and when unleaded fuel came in I smiled when everyone panicked and wanted hardened valve inserts.The jeep engine was developed well before lead was added to petron universally. You may harden the valve seats but that does nothing regards upper cylinder lubrication or valve stem lubrication, I suspect that you may have a timing issue as the dissy.needs to be altered to time it up for unleaded fuel. On the subject of adding diesel, last year I went around garages that had sifoned petrol that people had put itno their diesel cars, I ran my jeep all season on this and my theory is this, some diesel reached the valve stems as well as the upper cylinder bores, also some sat on top of the pistons and formed a better compression. The only thing to watch is that some may find its way into the sump and dilute your oil, I havnt put this very well but it all worked for me, yours, John.
