Installing valve springs has never been easier. With the help of this valve spring compressor tool, it only takes a matter of seconds to install the valves spring assembly in your vehicle. Simply align the holes on the aluminum body of the valve spring compressor with the ones on the head, bolt it using the provided short bolts, place the valve spring, retaienr and retainer cap on the retainers, bolt down the long bolt, place the keepers using the magnetized screwdriver, and voila! it's done. For Mitsubishi 4G63 and 4G63T.
We at Euroexport have been making our valve spring compressors for Honda for almost a decade. They are machined, anodized, and laser engraved in the United States.
Tips/Instructions for use:
If using with the head on the block, cylinders need to be pressurized to 100PSI to prevent the valve from falling into the cylinder. If using with the head out of the engine compartment, put something bellow the valve to keep it pressed upward.
Align the holes on the tool with the one the head, and place the shorter bolts and washers to secure the tool.
Place the retainer cap on top of the retainer, lubricate the long bolt with provided grease and start turning the long bolt clockwise with the help of a wrench (14mm) to apply pressure to the retainer cap and compress the valve spring until the keepers are completely visible and can come out.
Using the magnetized end of the screw driver remove the keepers.
To reinstall the valve assembly, place the valve (if removed for some reason), valve seals, valve spring, and retainer; compress the assembly using the same steps as above.
Place a small amount of the provided grease on the flat tip of the screw driver and place a keeper over it, the grease will hold the keeper in place and allow you to place the keepers easily.
Once keepers are in place, start turning the bolt counterclockwise to relieve the pressure of the valve spring.

Fast shipping and a well made tool that makes life a lot nicer. My only complaint would be that there is not enough relief space machined into the tool to clear the uncompressed valve spring without unbolting the tool from the head. In all fairness, I did not read the instructions, so it is quite possible I missed something obvious but this is a pretty simple tool and not exactly my first rodeo. Overall I would absolutely buy from Euroexport again for any other applications that came up.

Simple and very easy to use and made perfect. The tool pays for itself the 1st time you use it. Would recommend to anyone looking to do a valve job on a 4g63 motor.

This spring compressor is possibly the best on the market for the 4g63 platform. I can do a full set of valves in a matter of minutes with this. Amazing tool and it comes with a nice magnetic screwdriver so no need to fuss with finding yours if your toolbox is a mess (like mine always is).
