Engine and machine shop tips and tricks.

BOLT COLLET

To precisely shorten bolts in the lathe, I made slotted collets for each bolt diameter. They are fractional in length to measure off the end, so you know where to cut for your length. I’ve used large O.D. valve guides and aluminum round stock. Just make the collet big enough to clear the bolt flange, hex or socket head.

MILLING VISE GRIP

Improve the grip on cast parts or multiple parts in a milling vise by inserting gasket paper between the vise’s moveable jaw and the part. Gasket paper is thick enough to conform to irregular cast surfaces and/or compensate for small differences in multiple parts, yet it still compresses tightly to grip the work piece(s). Plus, it withstands coolant and cutting fluids. We pre-cut business-card sized pieces from gasket paper rolls, so they’re handy and ready to use.

ROD BOLT INSTALLATION

When installing aftermarket rod bolts, in addition to checking the under-head radius clearance, if the nuts are flanged, always check for clearance on the cap where it seats. On some rods, the O.D. of the flanged nut will hit before the face does. It will stress the fastener and distort the housing bore when torqued. A simple piloted spot face is all that’s needed to fix the issue. A slight radius edge spot face is best, if available.

NEW NOZZLE

I can’t be the only one who opened a brand-new can of carb or brake cleaner, set it on a workbench and it gets knocked off and “snap,” the nozzle is broken and it’s useless. I started taking the nozzles off the popular yellow and blue canned WD40. Remove the red nozzle off the brake cleaner, gauge the hole with the back of a drill bit. Then, by hand, just bump the hole in the new nozzle out to fit. No more broken aerosol plungers and the straw is always there. Once it’s empty, I just switch it to a new can.

CORRECT BOLT LENGTH

Many older, inline engines have water pump bolt holes that go all the way through the front of the block and can easily contact the front cylinder, if the incorrect bolts are used. I have seen a few engines ruined from having the incorrect length bolts pressed against the outer cylinder wall. It’s important to verify that there is bolt-to-cylinder clearance or add this to the required checklist if the customer is assembling the engine’s accessories.

HONING-CUTTING OIL

This helps save me time, money and storage space. Honing oil is not just for honing, it is a cutting fluid. I use it on taps and dies, for cutting lifter bushings and machining on my lathe. I also use it for surfacing aluminum heads on my CBN surfacer for a nice finish.

QUICK VALVE SPRING CHECK

For a quick check or if I don't have a spring height mic that is small enough, I use a telescoping gauge to get the height off the head. Then I have various valve adjustment discs I use to simulate the retainer thickness and I don't have to re-adjust the snap gauge for the retainer thickness. I just set the gauge on the disc.

If I’m not using torque plates, I tape up both sides and trim out the bores. I use painter’s tape, which comes off easily and doesn’t leave any glue residue. I get much less oil in the spray washer this way.

Pennzoil and API on Developing Motor Oil Standards

For more than 90 years, Pennzoil has worked alongside the American Petroleum Institute (API) to ensure Pennzoil products meet – and often exceed – the stringent requirements of motor oil specifications implemented to best help protect the performance of your engine.

Nitrous Update

The use of nitrous oxide in diesel engines is not a new concept. In fact, it has been used in drag racing for decades. However, it is only in recent years that it has gained widespread popularity in the worlds of diesel truck pulling and drag racing. Now, it seems as if almost everyone in the competitive scene is using it. 

Heavy-Duty Diesel Engines, Equipment and Replacement Parts

Relying on OE manufacturers like Caterpillar, Cummins, Detroit Diesel and Waukesha has always been an option, but diesel equipment owners are now more than ever seeking the aftermarket as a more viable solution for replacement parts.

Diesel Piston Technology

Diesel and heavy duty go hand-in-hand. There’s no way around it. High compression causes high cylinder temperatures, with peak cylinder pressure often as high as 2,700 psi (or higher). This high pressure and high heat only have one thing in mind, to beat relentlessly on the first thing to get in the way – the pistons.
