Re: '05 5.3l mysterious misfire
Pushrods are true/straight, valve springs look ok and problems doesn't get worse in high rpm. I lapped all the exhaust valves, the intakes looked fine. honestly the exhaust even though they were leaking looked normal for todays fuel and sitting for an extended time, I don't think lapping the valves is going to fix my problem but at least I can eliminate it off the list of causes. Going to put it all back together tomorrow and check with thermo
