Walked out to my Ford V10 this morning with my toolbox in hand, ready to fix this blown spark plug myself — just need to know whether Time-Sert or Heli-Coil is the way to go. My 2000 Ford Flair 31A with the 6.8L V10 just blew a spark plug going uphill - sounded like the exhaust fell off until I realized what happened. The shop is telling me this is apparently a "common issue" with these 2-valve V10 engines, which is just fantastic news after being stranded on vacation.

They're giving me options for thread repair - either a Heli-Coil insert or something called a Time-Sert. I've heard horror stories about blown plugs on these engines, but I've also heard that proper repairs can actually fix this permanently. Before I spend my hard-earned money, I need to understand: are these thread repair methods actually reliable for V10 blown plugs? And please tell me there's a way to prevent this nightmare from happening again - proper torque specs, anti-seize compound, whatever it takes. I just want my RV running reliably again. …more

Opened my wallet for a new catalytic converter, cleaned the MAF sensor, checked every vacuum line, and swapped the fuel filter on my 2014 Ford V10 motorhome — still getting P0420 codes and intermittent surging. Some days it runs absolutely perfect, smooth acceleration and no codes. Other days, especially during acceleration, I get this annoying surging that makes driving unpleasant, and that's when the P0420 code shows up on my scanner.

I've been methodically working through potential causes and have replaced quite a bit already: new MAF sensor, both upstream and downstream O2 sensors, checked fuel pressure (it's good), tested plugs and coils, cleaned the throttle body thoroughly, and even replaced the right side exhaust manifold gasket after noticing some seepage there. Despite all this work, I'm still getting the same P0420 code and surging, and my scan tool consistently points to issues on the right bank.

What's really puzzling me is the connection between the surging and the P0420 code - they seem to occur together. Could there be something I'm missing with the exhaust system that would cause both symptoms? I've already addressed the right side manifold, but I'm wondering if there's more to this V10 exhaust system that I should be checking. …more

Three distinct sputtering sounds keep coming from my Onan generator that fires up perfectly but dies out after running for a while. Multiple service calls and repairs have been attempted, but the problems persist intermittently, making diagnosis challenging.

The repair costs are accumulating significantly, and I'm reaching a decision point regarding whether to continue troubleshooting or consider replacement options. What criteria should I use to determine when total repair investment justifies switching to a replacement unit? Are refurbished Onan generators a viable alternative, and what factors should guide this repair-versus-replace analysis for intermittent generator failures?

(Note: This is specifically about my RV's Onan generator, which I'm referring to as my 'Jenny'.) …more

Replaced my RV's exhaust manifold last month, but it only acts up when it's above 80 degrees outside — runs perfectly during cooler weather. Our 2014 Fleetwood Bounder 35k has what I think is an exhaust manifold problem, and our VacuFlush toilet system has completely lost suction.

I'm having trouble figuring out what type of shops or mechanics actually work on these specific RV systems. Are these the kind of repairs that regular RV dealers handle, or do I need to find specialized shops? I'm worried about taking it to the wrong place and getting told they can't help.

Any guidance on what types of service providers I should be looking for would be really appreciated. Thanks for helping out a newbie! …more
