comment Best way to remove broken bolt from intake manifold (broke nearly flush)?
The odds on this actually working though, in my experience, are near zero. The reason it snapped off to begin with is most likely due to it being VERY stuck. If you can't solve that root cause, the extractor will fail even quicker than the original bolt did...

comment Half of my cylinders aren't firing. Is it safe to move my car to a garage (~30km)?
I had a confined cat fire (melted it into blocking the exhaust) just after having a power transistor fail and rolling to a stop (injectors still firing).

comment Impact vs. Regular Sockets
They seem to be stiffer. I had an oddball size bolt get stuck recently so I went ahead and tried my regular socket on my impact. Gloves, goggles, etc just in case I shattered the socket. Bolt wouldn't budge. Walked down to the store, plunked down $20 for the right impact socket, walked back, zipped it right off of there. Did some experiments and it seems the "regular" sockets flex and absorb some of the impact, lessening the effectiveness, whereas the impact sockets are stiff and transmit the pulses better.

comment How to cleanup disk brake rust rings
Just say no to cross-drilled rotors for cars. Slotted, if you absolutely must, but you pay a price in brake pad life for sure.

comment Daughter's 2005 Nissan Sentra 1.8 SE - No Low Beams - High Beams Fine
I had the stalk switch fail in one of my cars in exactly this way. Everything except low beams worked. $15 for a new stalk, $15 for a steering wheel puller, & a couple hours of labor.

comment Oil leaks after oil change - shop says engine oil pan gasket needs to be replaced
30 minutes seems really optimistic. I'd budget 1-2 hours for a non-mechanic to do it.

comment How can you tell the oil needs to be changed?
Based on the reading I've done and the anecdotal evidence of engines I've had knowledge of, the degradation of oil over time is not nearly as large a concern as the contaminants (built up by mileage) in the oil.

comment Semi synthetic oil engine break-in
Well, most likely fresh rings and a hone job, probably not a full rebuild... :-)
