nest to setting the ring end gap on an engine and the rod bearing clearances, torqueing the heads on is the most important repair with repercussions, of biting you in the ass, aluminum is a junk metal for automotive use anyway, but beings they are using it, understanding its short comings is everything, i always set aside the time involved in clamping two pieces of aluminum together, aluminum head to cast iron is straightforward as you have one metal with integrity, alum to alum is critical, i always tight torque to half go get a cup of coffee and let it set and conform to clamping torque then proceed in 15 lb increment up to torque, your thread repair was mandantory good job, take a bow

Im like timesert I dont pull out.
I have 15 kids.
Props to having pride in your work and more importantly, having quality work ethic. Its a rarity.
The fact that you did all 10 head bolts is a reflection of that. Most mechanics would've said well they aint stripped so why waste my time.
You did the right thing. There was a recall on those heads(from what ive heard) and you just fixed the problem permanently(hopefully.
Not to mention i can only assume the customer paid all 450 dollars for the time serts so he might as well get all the inserts he paid for.

Great company? You're kidding. My Rav was in the repair shop more than on the street (warranty thankfully. company Tundra leaked like a a colander- (dealer never really fixed it- antifreeze, oil, tranny fluid) and my niece's Lexus was the worst car I've ever been around (ECM's - 2 of them burnt up) calipers frozen, head gasket blown (101, 000 miles) dash gauges out at 114, 000 miles and engine blown-seized at 128, 000 miles. No thamks

Anyone that has ever carefully tightened down a bolt and then heard that gut wrenching crunch was right there alongside you on that final torquing. You appear to be a very caring mechanic who makes sure that he does everything correctly, and that gives credence to what another well know car guy always says at the end of his shows, and that is, Good mechanics aren't expensive, they're priceless! Great video sir.

How on earth can that torque wrench possibly 'know' when it has rotated through 90 degrees? It's easy enough with torque- the bar is deflected a certain amount and a sensor of some sort gets tripped at the required torque figure, but degrees? Does it watch its surroundings and beep when it sees they're 90 degrees from its starting point? Just amazing!

You have similar practices. I don't go torqueing from the gate. I rather do them in steps. Yeah they do look tight! No wonder threads stripped and the others so difficult to remove upon disassembly! Makes me cringe to tighten them so much! I experienced similar on transmissions, of course bolt sizes & torque was different.

Eric it seems to me that with all the labor cost (much time, the head work farmed out, gasket parts, shop parts, and insert kit that this is a incredible expensive repair that would well exceed the true real value of the vehicle? It's not like it is a rare sought after exotic sought after auto, or belongs to aunt Nellie.

A couple of times I have seen you mention freight orders having their seals cracked and items stolen/swapped out. Is that a disease within the transport industry over there or what is it? We rarely get that over here in Australia. Generally freight just goes missing as a complete order. What's the go there?

I visited the timesert web site these puppies press fit them selves right at the bottom. You recall our hero, mentioning they go in easy then get tougher at the bottom. Thats the press fit. Go and check out the website. If I ever need to repair stripped threads. Timesert is the place Id be goin.

Awwww, the brake thing drop would've been priceless, . at least ya thought about it. i would've done it. while you were carrying, have josh ready with the brake parts, have hanna wiggle, jostle, lay camera over like it fell, not on you facing away on floor. That would've been great.
