This is a Public Service Announcement

Here we are on a Sunday, replacing the FOURTH heater core on one 2002 Dodge truck in the last 3 years. Made in China. This is an 8 hour job, plus A/C. Warranty work. Again. Money lost, customer displeased…
this hurts everyone.

Notice the “RETURN” shelf.
2008 Ford F150 cam gear “phaser”, made in China. In stock at the local dealer.
2010 Ford Focus transmission mount, made in China.
2012 Volkswagen Tiguan, engine oil cooler seals, made in China.
2009 Toyota Camry, airbag “clock spring”, made in China.
2016 Subaru Outback, Fel-Pro engine intake manifold gaskets, made in China.
Not pictured: 2001 Chevy Corvette, front turn signal lamp/lens, GM box, made in China.

When your parts don’t fit correctly, or I can’t trust them, what do we do?
Call out our local government representatives and ask why these parts are not made in America, to higher standards. I spend more time and patience trying to find the best parts for your ride, and sometimes… this is the best that I can do. “screams aloud”

2016 Hyundai Elantra GT, 84k miles, towed in as a “crank, no fire”. It sounds like no compression, hence the “no fire”. Customer states it died at the stop light. Yikes. Most any other shop would say, “it needs an engine”. Not here. We want to know the truth of the matter.

Check Engine Light fault code for intake camshaft position in relation to the crankshaft position. Saw that coming. We removed the engine “valve cover” to examine the camshaft, timing chain, and valve train, and the answer was obvious. The variable intake camshaft gear… the bolts that hold it together had removed themselves. Aye aye aye.

These Kia / Hyundai engines are “valve benders”, and usually that turns the engine into a boat anchor, but I wasn’t convinced. The gear separated from “drive” and left the camshaft in a kinda neutral position, so we ran a camera into the spark plug holes to see the valve faces. Wow, it looks like every valve is seated and no damage has occurred! Chain failure at idle is a much better scenario than high rpm failure.

We removed the oil pan and the remnants of the failed bolts and gear, updated the chain and variable valve timing gears, resealed everything, and boom, a good running engine.

Note: we removed the NEW cam gear bolts and added “Loc-Tite” to make sure this never happens again. If only the engineers thought that through? Well we did. Quality is how we roll. Comments in pics
