i wonder if you was?

last day, i was work on jeep grand cherokee to put cylinder head back on engine block. one tech who work in automotive industry for many years like 20 years. he just tight camshaft thrust screws by ratchet and torx socket NOT torque wrench......

i told them that engine assembly need be torque on specific to prevent the problems... they dont said about it. so i finish the engine assembly with my torque wrench on all bolts and nuts. i am little concern about it because i hate to finish the engine without have torque wrench to make torque on specific... i did torque the cylinder head with the follow the steps on paper from book.

i wonder if you just make tight by your hand with ratchet on something that must be torque on specific?? i always use my torque wrench to torque the oil drain so if customer complaint about oil leak from drain plug, i will said i use torque wrench to follow the torque speific....

Never on the oil plug, that's for sure. Wheels, head bolts, rod and main bolts, pressure plates, and that's about it for me.

Not sure what this cam thrust screw is you are speaking of though.

I torque everything I have spec's for and the proper torque tool ... as a home mechanic I don't have access to as many spec's as you do ... but to do a job properly you should use a torque wrench ... and when I pay a professional to work on my car I expect a professional job and that includes that the nuts and bolts are properly torqued

Alot of the old time mechanics claim they can feel the right torque by hand because they have been doing it so long ...

well that reason why my tech told me that he dont need it....

the camshaft thrust are to keep camshaft stay in location without make lot of endplay while running...

i work for Chrysler and Jeep dealership. i did repair the engine last day. i use all of my torque wrenches to make torque specific. sometime other tech have problem because they dont make right on torque specific.

I have good and high percent of FFV (Fixed First Visits).

Yeap, should have used a torque wrench for that. I use to work with a tech that would rebuild rears and close his eyes to set backlash. 70% of the time the cars never came back with rear end noises or future issues. But 20% isn't exactly a great come back number.

Anyone that says they can tell the torque by hand is flat out full of ****. If I am paying a mechanic to fix my car it better be done properly with a torque wrench. Anything less is unacceptable.

What about the other 10%?

That is about as accurate as the cops that say that they can estimate your speed when they see your car drive by. If the human hand or eye were that accurate, there would be no need for calibration tools, such as radar and torque wrenches. It is pure BS in my opinion for both to make such claims, and I have proven this fact more than once, but that is another story for another time.

I know someone who CAN get within spec. on backlash by hand. But I know for a fact that he's installed at least a thousand sets of ring & pinions. Your average dealership drivetrain / suspension tech doesn't do nearly enough.

But guessing torque? No thanks.

Especially on anything that's engine related. Oil pan, heads, valve cover? You better believe I torque those to spec.

 

[OctaneMotorsports]

That's okay. A guy I work with uses an impact gun to remove and install spark plugs.

 

[iiibdsiil]

What about the techs that do the oil drain bolt with the impact?

That is the percent we don't talk about.

That is plain scary and the tech is extremely lazy ...
