Which torque wrench

[Beck]

I have been having a head gasket leakage issue on a new motor. My 1st concern was correct torque specs.
I did the home garage torque wrench test with hanging a weight on the handle and doing the math (arm length x weight / 12 = torque).
It turns out my torque wrench is 13.2% low. What was 90 ft lb was reading 104 ft lb.

Long story short, it's time for a new torque wrench. I believe the 150# max is the size I want. I don't recall having to torque above that. My current head bolt toque is 130 ft lb. I have a 3/8 drive which is probably junk too.

This one keeps popping up in the reviews, but I always considered it a lesser brand. What you think? Other recommendations?

I don't think I want a digital one. My hearing is really bad, and I cannot hear them beep. It would be like a beam wrench for me. I would have to watch the digital display.

This one gets great reviews too. It's 4.5 times more expensive but may be worth it. It says the handle vibrates along with the beep, so it would work for me.

It has a 2% accuracy where most others have 4%. It also goes to 250 ft lb if I would ever need to.

I don't know if it is worth the investment for me.

I have 2 of those cheap ones. I have never checked them with an accurate source, though. I have a proto from 1972 that I still use. Several years ago, I purchased a slightly used proto for my son. In comparing the 2 protos, they are very close. In regard to your question about higher capacity, I just purchased a cheapie off Amazon that was a 250lb unit. My wife's new edge has lug nuts torqued to 162 ' lbs. I won't use it for lighter stuff, just the heavier units. One of the cheapies I just bought is a 1/4" drive inch pound unit. When I was working on the 2015 charger a few weeks ago, everything on the top end of the engine was inch pounds. The only
inch wrench I had was a 3/8" beam style. The graduations are close enough that extreme accuracy won't be possible. I think you need to see if someone can calibrate your existing tool or find something a little better. However, I don't really know what to recommend. I looked at gear wrench units before I bought the 1/4" unit and found some failure issues so I shied away from them. I have several of their tools and they have all been good but they're not precision tools. Sorry I'm not more help.

[Beck]

The prices I am seeing for calibration is around $75. By the time I add shipping both ways I can pretty well pick any new one I want. Haa. Plus with the current shipping situation I may not ever get my old one back. It would surely be a month in the shipping dept. I'm always in a rush. I want it NOW.

^^^^
Good point.

I have a Craftsman that about 20 years old, maybe more, and it has always worked well. It got used only occasionally over the years, never abused, just hung on the wall in the original package. When I decided to built the engine I am currently working on I wanted to check it to see if it was still accurate so I took it to my nephews shop, he owns an auto repair garage. I checked it against his "good" digital Snap On and it was exact. I don't know if the Craftsman tools are any good nowadays, but I suspect they are not.

I bought the cheap one from Amazon. I got an email saying it is scheduled for delivery tomorrow.
