Re: Frustrated overheating, timing issue?
I'm just a half a** shade tree mechanic but unless I missed it, I see nowhere where you performed a compression test. This will give you some insight as to the overall mechanical condition of your motor. Not a perfect science but a good gauge to go by.
I would suspect you have a leak opening up with heat added to the equation, could be a head/head gasket or cylinder wall crack.
If the compression test is a good report, then look into the fuel delivery and ignition sources.
The important thing is quit throwing money at it, take it to a reputable mechanic who has the knowledge to sort it out.
