If you’ve ever tried to replace the valve seals or keepers on a 3.7L V6 or 4.7L V8 engine, you must’ve realized it’s nearly impossible using other cheaper special tools.

Our special tool allows you to:
– Quickly and easily compress/decompress, remove and install valve springs, keeper and seals in a very controlled manner. You no longer need to strain your arms trying to hold the spring compressed while trying to install keepers.
– Allows you to keep the valve springs compressed for extended durations while you take your time re-installing and aligning the valve keepers.
– No need to pull your engine from the car. Just remove the brake booster as you normally would have, to access the rear cylinders.

Works on most early Chrysler / Jeep / Dodge 3.7L V6 and 4.7L V8 NON HEMI engines including:
1999–2009 Jeep Grand Cherokee
2000–2007 Dodge Dakota
2000–2009 Dodge Durango
2002–2007 Dodge Ram 1500
2006–2009 Jeep Commander
2007–2009 Chrysler Aspen
2006–2007 Mitsubishi Raider

NOTE: The tool you receive will be the metal-reinforced version, not the yellow piece shown in the video. They look and function the same way.

Fix blue fumes coming out of your Dodge or Jeep exhaust. If you’ve ever used the Dodge special tools to replace the valve stem seals or keepers, you must’ve realized it’s nearly impossible to do this using those special tools while the engine is still in the car. Good luck doing this by yourself with only 2 hands :). I made the special tool in the video to allow you to not only remove the valve springs, keepers, and stems, but also re-install them all by yourself and can be done in a few hours.

Additional info:
– It’s easier to use than the other specialty tool on the market.
– Works on most early 2013 and older Chrysler / Jeep Dodge 3.7L and 4.7L NON HEMI engines.
– You may need to temporarily move the brake booster out of the way to access the 2 rear right cylinders on a dodge ram.
– You will need to remove the rocker arms (a simple flat head screw driver is all it takes).

Keep in mind if this is your first time doing this repair, you’ll need:
– To remove the rocker arms (a simple flat head screw driver is all it takes)
– Air compressor (at least 90psi)
– large plumber’s wrench
– tweezers
– Magnetic pickup tool
– Vaseline or some gear grease

KEITH S says:

In the midst of replacing valve seals, springs, rockers, lash adjusters on my 03 Durango. Tool is well made. This is not a quick job. Follow the technique in video for getting valve locks on. If you have a 1st gen Durango, accept the fact that the power brake booster is going to need to come out and do it before you start on the driver's side.

video is good but sniffle is annoying af and clicks

KEITH S says:

Purchased tool. Going to be replacing valve seals. Thinking of putting in new rocker arms and lash adjusters while I'm in there. Engine has 170k miles. Thoughts?

NosCraze says:

Update! Ordered the tool last week along with 16 hydraulic valve lifters. This thing worked like a charm! No issues whatsoever. No more blue smoke or lifter rattle. 100% recommended! Thank you!
