Mechanic ON Duty! Ask me a question!

You could have them make one. We had Penske make suspension for Viper, Lamborghini and Ferrari models I worked on.

Got a 2015 GMC Terrain - all of the sudden the driver side wiper doesnt move. I can manually move it and nothing appears broken ,but only passenger side wiper moves. What might it be and how pricey could a fix like that be? Thx

Lift the cap at the pivot and make sure the nut for the wiper arm didn't loosen.

Will check it thx

Moar city driving?

So what is your take on Amsoil synthetic? Compared to Mobil 1, Royal Purple etc?

I have a 2005 Astro van...... the past week there’s been strange noises from the back doors...... like r2d2 on alcohol..... not constant..... someone suggested it may be the door lock actuator. Everything else is normal although on occasion I have to manually unlock. What say you.

Mobil 1 is the bench mark
Look at a supplement called Prolong. Really works, lowers friction

Stop jerking and sucking and everything will fix itself!

Is castrol oil any good?

Anyone remember slick 50 ?

Amsoil, hands down.

I was tasked with making transmissions live with over 3X the OEM power. Mechanical failures aside, the gears were getting through both Royal Purple and Redline and scuffing. When I moved to Amsoil of the same viscosity, the gears stayed clean with no scuffing.

Yeah. My old boss sold it. Same with Zmax.

Cool, I don't see it anywhere now!

Here's a perplexing one -

My car, a Fiat, which we beat the hell out of in the back country started making a rattling noise from under the hood, as if it is a major suspension part with a problem and we can't find it parked.

The tires are pointed perfect. The alignment is perfect. Steering perfect. Tire wear perfect. Handling PERFECT, even at 100 mph. Yet there's this clunking rattle on bumps.

Any clues?

The temperatures required to bond teflon to an engine part would be so high the engine would nuke itself first. Total scam.



Front swaybar links

Either a strut, or the intermediate steering shaft. Fiat loved to retain the strut top with a plastic clip. This of course loved to break and the strut top was free to pogo around in the wheel well.

2019 check equinox. Starts fine. Put it in gear and it stalls.

Take it to the dealer.. lol. Could be a flash, or the torque converter clutch is coming on when it shouldn't.

I used to use it in all my cars. I didn’t have any down here and I just blew the second motor in my 2009 X5 in 14 months. It’s the V8, are they known to have problems? The first one blew at 67,000 miles and the second (that came from a crash) blew at 50,000. I have always had big motors and have always taken good care of my cars. Now I need another car and am thinking about getting a new one just because it comes with a warranty. I have never bought a new car before. And now I’m waiting on another crashed motor because there are no Parker rebuilds down here.

I have replaced the struts myself, no plastic clip on mine.

It has 4 bolts and a large center bolt. I could check them though.

Slick 50

I had a Geo Storm GSI back in the day. The engine started getting noisy for whatever reason. It was not a clicking or banging, it was just loud, where you could hear every part. Very strange.

I poured in a bottle of slick 50 and it gained a lot of horsepower and ran totally quiet. The oil changes were all up to date. After the next oil change it was still powerful and quiet.

I’ve got an 04 Jeep tj. During cold weather there’s a whistle that comes from under the hood at idle speeds - when parked, at stop signs, etc. I never hear it except in the winter on cold days. The colder the day, the louder it seems to be. Exhaust manifold? Bearing in a pulley? I’m no mechanic and I don’t want to work on it only to find out I haven’t fixed.

No performance problems just annoying; and thanks! It’s a cool thing you’re doing.

I have a 2002 gmc sierra 1500. For the past 6 months im hearing a ping type sound. A popping sound that i think is coming from my gas tank after ive ran the truck this sound occurs several minutes later after turning the truck off.

Its usually only once or twice that the truck makes this sound.

Pull the dipstick out and see if it goes away.

The 4.0 had two fittings on the valve cover. One was grey, one was black. The grey one (toward the firewall) had a built in orifice for the PCV system. If this got swapped for a black one then you had unregulated wide open manifold vacuum drawing on the crankcase. This caused the seals to squeal as air went past them.

I have a question, if you don't mind

My 92 Silverado dually is hopping at times, usually when I begin to brake at speeds between 50-30, it stops the slower I go, plus I have to let off the brake and take another stab at it to see if it will be smoother, that's before reaching 30 or below
I know the rotars are probably warped, but could there be anything else I need to address to make sure the hopping stops, I want to try to get this all handled in one trip to the shop

People post comments on car repair blogs and they always say the steering wheels shakes, but in my case, the steering wheel is the most stable, albeit it does shake, the whole truck is violently hopping much more than my wheel shaking

I just checked the struts. Everything is tight. 3 bolts around the outside, not 4, and probably not mandela effect.

This fiat is WAY beyond anything sold in the U.S., it is a copy of a Subaru outback.

You don't need to worry about driving that one hard offroad, the problem is it is getting old.

If it is the intermediate steering shaft is there a way to quiet it down or am I doomed?

It has power steering but not electronic steering.

mass airflow sensors are notorious for rarely actually failing but instead becoming contaminated with dust or grime.

It doesn't take much, some could get in if your air filter is clogged, not installed right or even while you are changing the filter.

The trick is to be very gentle cleaning it because the actual sensor is easy to ruin with high pressure or the wrong solvent as it involves a tiny element. Since this is a 100 dollar part it wouldn't hurt for a guy to try to fix it for free, like I have about a thousand times

If I were you and I had a Fiat I'd drive it into the lake and report it stolen.

Fix It Again, Tony
