Imagine this… you’re in your shop wrenching away and you get stuck. You just hit a wall and no matter how hard you try, you can’t find a next step. You reach for the phone and hit speed dial. The number saved in your favorites is your personal coach at How2wrench! No sitting through hours of YouTube videos, websites or giving up!

This service is intended to fill the gap in many areas of need. Let me list a few:
The DIY person needing help with a specific skill
A tech just needing an advanced lesson or next step in their knowledge base
Someone who would give anything to drop everything and move to a tech school but life just didn’t deal those cards. They understand the learning curve may take longer but are relentless in their desire to learn.
Observant parents lacking the skill sets to teach their kids mechanics but see them craving to use tools and their hands.

Some of my favorite videos are the diagnostic "how to's". One can never stop learning tricks of the trade. Thanks a bunch!
How does the "gas being left on" bend a rod? gas left in while running? or the petcock? (vacuum operated)
I really thank.you for sharing what you know. your approach to motorcycles is so calm…
you are an inspiration for me, as a mechanic.
Excellent video! Using critical thinking skills and evidence collection is becoming a lost art. I found this video in the search for tips… regarding the cause of a low compression test on one cylinder of a EVO Harley. 🙂 Subscribed to the channel, keep up the great work!
I bought a cheapo from amazon and struggling to understand the setup — Im not getting a reading on the "drop" gauge when the first gauge is outside 25-35 psi. You set yours to 100 (easy for the math etc). I have my compressor set to 100 — could a 2nd inline regulator cause this issue? or it there something else im missing?
It seems the cheap kits show you a result based on the "balance" between the gauges, however at a much lower psi rating than the pricier ones (and recommended psi).
I presume one needs a constant flow of air coming in from the compressor to the kit but im not sure why mine sucks so bad? Just saw a guy make his own and it went to 100psi on the first, the 2nd was just another gauge showing the loss..
could I not then set my compressor at 100 and plumb an inline compression gauge to read the "loss"?
air inject into your thumb
2:20 very important info I was looking for when I finish building my own leak-down tester. Thank You very much!
Hi,first of all thank you for all your videos,you are doing a really great job!i wish to ask you something about a mechanical problem of a kawasaki er6n,can i??
Working on my SV1000. HF leak down tester is junk. Cam timing is never like the service manual either. New cam chain ordered. No specs in the manual for a stretched cam chain either.
