AUTO Solid Valve Spring Compressor Automotive Tool Set Repair Tool Kit

Works very well on small engine cylinder heads. Very happy with it.

I couldn't figure it out at first but it didn't take long. I tightened it down onto the first valve and it started to bend. I got furious because it felt kinda lightweight when I pulled it outta the box.I started reading reviews and found other people who bent theirs terribly. I thought I had been ripped off.Until my dad came by while I was tightening (and bending) the tool. He tapped the side with the valve stem gently with a rubber mallet and the valve broke free from the seat.So if your tool is bending, then you are using it wrong. Give it a light tap once you have it tightened down to break the valve seat free and it works great.I used it on a 98 frontier (ka24de) head and it worked great. It didn't bend from spring pressure at all (it only bent when I was using it wrong)

Worked on one head…not sure how it would stand up to long term use as it feels a little flimsy

The wife’s timing belt broke! Luckily it only bent 2 valves with minimum damage. This thing worked perfect. No instructions but it’s pretty common sense how it works and I had the valves changed pretty quick. Nice add to the collection imo

Plan to first spend some time and bring it into operating conditions. Mine came with one of the arm threads full of paint so had to use a tap to clean it up. The screws were having some light rust so washing, thread chasing, and oiling was in order.After all this the tool performed as expected. I work on a Volvo white block engine (BT5254T4) and the arm is plenty long. There was no issue with bending. The springs were easy to compress. I used the 23mm adapter.Bottom line: this is a home mechanic tool to use once in a while. It get's the job done relatively easy. This is NOT a pro tool! If you run a shop or do this kind of work often for your friends or hobby you should look for something more "pro" that easily clamps into place and securely stays there without fiddling or you paying much attention once you set it.For the price this is very good value, assuming that you have the necessary tools and knowhow on how to fix it. On the other hand you should have no business on buying it if you don't :)
