8MILELAKE Valve Spring Compressor Auto Compression C-Clamp Tool Service Kit for Motorcycle,Car,ATV,and Small Engine Repairs

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)

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 :)

Several reviews on Amazon downgrade this tool and say it bends easily and is useless. I find that hard to believe! It is made with strong tubing and solidly welded.In my estimation, the frame would be impossible to bend if you are only using it on a valve spring, and using it properly. By properly, I mean all forces centered on the valve stem, and nothing binding. If you misalign the centers, its likely to skew things and might bend.Unfortunately I had to return it because none of the attachments fit my valve spring. The largest provided is 30mm. As you can see in the photo, I need something like a 32mm to properly seat on the valve. Being too small, it kept slipping off, which posed a safety concern.Even though it didn't work for me, during my attempts, I did learn several things.Before starting disassembly, rap each valve from the spring end with a rubber mallet. This helps break things loose.A little grease on the threads helps things go smoothly.As does a dab of grease on the screw end where it presses on the valve face. (keeps it from skating around)Take time to make certain all forces are centered on the valve stem.If you are turning the screw and nothing is moving, STOP. Something is binding.

This is a great tool! The price is amazing. So much so, that I was shocked at how well it was made and how well it worked. I'm doing the head on my 2001 Nissan Frontier and could npt find a suitable tool for less than $40. This one is perfect for the application, for less than half that price! I hate that I may never have a need to use it again after this engine rebuild, but for the price it was still worth every penny.

The kit is ok, but the main piece is made of cheap steel and bent on me after doing one cylinder head. You definitely get what you pay for. This is an ok tool for a one time or sparse usage.

Happy with my purchase. It got the job done.

The valve spring tool works unfortunately on one of the threaded ends the ball and spring that lock the heads on just pops out and goes flying. This happened after the first use

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

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

Bent on the second valve. Rebuilding an xs400 engine. Nothing big. The bar bent on second valve. I will be returning and buying something better. Update-Changed my mind, keeping it. The bar is garbage so I bought an 8 inch C clamp to use with the compression rings. Works like a charm now. Get yourself a big C clamp if you buy this kit

Product seems okay for the price, but check your product as mine was clearly used. Thankfully not damaged but threads had a good amount of debris that needed to be cleaned out

The media could not be loaded. Putting together a set of LS heads and wanted to get a tool I could use on multiple vehicles and this is it. Won’t ever need another
