Valve LeakerA QUICK TIP
Sometimes you need to just remove a few thousandths from a valve tip to get clearance on an OHC valve adjust that uses pucks. I found that grinding on valve refacer can sometimes take too much off, especially on very small stem valves. For fine adjustments I use a machinists block covered with a sheet of 400 grit emory-cloth and I remove the V-block from the valve refacer to use as a holder for my valve. With both on a flat surface I can make a couple passes across the emory-cloth with the valve tip and remove a thousandth or two at a time, while keeping everything parallel. This worked well recently with some small titanium valves for a motorcycle head.

Valve LeakerLIFTER BORE CHAMFERING TOOL
I purchased a one inch Chamfering cone and welded a 6 inch extension to it. This is for chamfering the top and bottom of lifter bores in blocks. This saves time and leaves a better finish than doing them with a stone and grinder.

Valve LeakerCORDLESS THREAD CHASING
I use a worn-out tap to clean threads in blocks & heads. I chuck the tap in a cordless drill that has a ratchet clutch. This way I won't break off the tap if it hits bottom. This greatly speeds up thread cleaning jobs.

Valve LeakerINTAKE FIT
I use a serpentine belt to lift blocks and cranks. No more need for chains and bolts or wrenches. It won't harm machined surfaces and this belt can lift a fully dressed 5.9 Cummins. I've been using these for years and never had one break.

Clean FuelLIFT BELT
I’ve found that those stubborn press in galley plugs can usually be removed fairly easily with this process. First, and most importantly, you must center punch the plug as close to center as possible.Then, using a Unibit, drill through the plug. Next using a carbide burr and die grinder, grind one side as close to the block as possible without breaking through. You don't want to grind into the block casting. Finally using a hooked style tool, pop it right out.

Clean FuelINTAKE SCREENS
Screens on your doors and windows work to keep debris out of your house. New intake manifold gaskets for 3.7L and 4.7L Dodge and Jeep products are designed to do just that. These new problem solver gaskets include a special stainless screen that keeps debris from a previous engine failure out of a rebuilt or repaired engine.

In many cases a valve seat explodes and pieces go back up the intake and get lodged in the plastic plenum. When these pieces come out at a later date they can destroy the rebuilt engine. By using these intake gaskets the debris is harmlessly captured by the screen and can't do any damage. Most production builders currently require a new plenum purchase or the warranty is void. Cleaning out the old plenum has proven to be ineffective in getting all the debris out. At over $400 for the plenum many try n vane to clean the old one and the added protection of the screen will help protect the job. If you are not familiar with the issues these vehicles have, there are a bunch of videos available online showing what goes on. Check out, "Whats in a 4.7 intake".
