For the past 20 years, I have been buying bicycle inner tubes at the local hardware store to replace the neoprene sleeve on our universal cam bearing tool. The inner tube costs range from $5.99-9.99 and will give you more bang for the buck. Cut the inner tube…

On FE Fords it is common to restrict the oil flow to the rocker arms. To do this, simply drop a Holley main jet, of the restriction size you want, right into the oil feed hole under the rocker shaft. If you want to pull it…

I came up with a simple way to keep lifters organized and in one place. This was easy to make with some scrape wood, some paddle drills and a few tools around the shop. It is a handy way to transport them without getting them mixed up. I came up…

Sometimes a failure or even a comeback seem obvious and we point a finger at a failure point and assume that it was defective. A little investigating might show a cause and effect scenario and what might be thought of as defective or failing…

Timing components are more complicated then ever. Today’s components were designed to last well over 100,000 miles, with proper maintenance.

When reassembling late model Chrysler heads with roller follower/hydraulic lash adjuster type lifters, I found that they bleed down much faster when turned upside down. When I used the vise it would take 2 or 3 squeezes and sometimes they would still be hard. I…

Our shop has had a cam analyzer for over 28 years. Recently I was at an friends shop and had to remember how we did it in the old days. He needed to verify which of the three customer-supplied cams to install because the previous shop had ground…

On the LS engine platform, when changing camshafts, the hydraulic lifters can fall into the oil pan on performance blocks such as the LSX. Instead of plastic buckets to hold the lifters up, these engines only have anti-rotational guides, that do not hold the lifters in place.…

1) COIL BIND-when a spring compresses solid before or during full camshaft lift. 2) RETAINER TO SEAL BIND-the distance from the top of the valve seal to the bottom of the retainer must be greater than the valve’s lift. 3) IMPROPER VALVE TRAIN CONTROL-any weak…
