Review on Lang Tools TU 15 Diesel Compression by Matthew Miles

So take the tractor apart to do a compression test. Buy a special adapter for this tool. Shut up, the shredder valve is leaking all the time. I can't read properly. Simply put, it's poorly machined and an attempt was made to use a PTFE washer to cover up the problem. It does not flow through the button, but through the thread. I'm so sad. Absolutely no quality control and they knew it and sent it anyway. I have requested a replacement. Update: New block arrived, shredder valve works fine but gauge showed 100psi. The sensor is annoying, at least the other part works. Just plan to get a new sensor for it. Or buy a better tool.
