Buyer Beware
We get a lot of calls from guys who’ve gotten a “great deal” on ebay on a seat and guide machine, valve refacer, you name it. Their only problem is they need a replacement part for the machine to make it useable.
Well, ya know what? A lot of the machines you’ll see out on ebay are there for a reason. In a lot of cases it’s because the manufacturer has gone out of business and replacement parts are no longer available.
Don’t get us wrong. There are some great deals out there but you need to be sure you have ALL of the information before you agree to buy the machine you’re looking at. If you’re considering buying a used machine from ebay or any other online source, be sure to ask questions and don’t hesitate to give the Goodson Techxperts™ a call to find out if replacement parts are available.
How To Use The Diesel Valve Relief Tool
The Diesel Relief Tool was developed for Goodson by Joe Mondello Racing Engines for use with a seat and guide machine or Bridgeport Mill equipped with a multi-angle valve seat cutting system. Use it for 6.0L, 7.3L Ford, 12 Valve 5.9L Cummins and 6.6L Duramax diesel engines.Wake Up Your Diesel : Building Diesel Horsepower
We know that increased flow creates increased power. That is the principle behind the Black Smoke Series of seat cutters that were developed for Goodson by Joe Mondello Racing Engines.
Unlike most valve seat cutters, these cutters are for specific applications:
- 7.3L Powerstroke Ford
- 6.0L Powerstroke Ford
- 12 Valve, 5.9L Cummins
- 6.6L Duramax
Honing Oil And Flex-Hones or Plateau Hones
There are a couple of reasons to use honing oil. First, the honing oil keeps the abrasive open. An ample, steady stream of honing oil is also necessary to flush away the swarf (used abrasive grit and cylinder material). This keeps the cylinder free of partially cut or rolled material that will abrade your new rings. It is just as important for deglazing, cleaning and maintaining the porosity of your honing abrasive.Comparing Valve Guide Replacement Methods
In this article, we’ll get into the various methods for repairing and replacing guides. These methods include knurling, installing thin-wall bronze guide liners, replacing insert guides, modifying the valve guide to accept oversize valve stems, replacing integral guides with false guides, and installing BronzeWall 2 coil-type liners.

ABCs of Valve Seat Stones, Pt. 2
Today, we’re going to share some tips on getting the most out of your valve seat stones.
Now that you’ve chosen your seat stone, dressing is your next step. The diamond is your friend, but only if it has a sharp point. The diamond’s job when dressing a stone is to remove enough material to expose fresh abrasive. A flat spot without a point will only close off the grains of abrasive and smooth over the bond, actually preventing the grinding wheel from doing its job.
The ABCs of Selecting a Valve Seat Grinding Stone
Valve Seat Grinding Stones have been around for a very long time. Back in the day there were roughing and finishing stones. This was because way back when seats were generally made from common cast iron or hardened steel. Two abrasive specs for the stone was all that was needed to properly grind the valve seat.
Today it is another story altogether as the seat material has become very specific to the applications found on today’s engines – alloys of multiple metals, powdered metals, super hard materials all designed to prolong the ability of the seat to seal against the valve head.
3 Honing Oils? What’s the Difference?
Goodson Tools & Supplies is proud to offer 3 different kinds of honing oils. This selection, of course, leads to the question, “What’s the difference?” So I’m going to give you the short version.
The HO series of honing oil was designed by the Goodson tech staff, to be clear and is formulated to offer the machinist a more aggressive result when honing various cast iron and steel alloys. Some say it has a drier effect that allows faster stock removal while keeping the honing stones, clean and more free cutting.
