Can you use solid lifters on a hydraulic cam?
It is possible to run solid flat tappets on a hydraulic flat-tappet cam and even mechanical roller lifters on a hydraulic-roller cam. Using solid lifters, even with the existing hydraulic springs, enhances top-end stability and fights the onset of valve float.
How do you know if you have solid or hydraulic lifters?
Another way to quickly determine solid or hydraulic lifters is to push down firmly on the lifter end of the rocker arm. Hydraulic lifters will allow for some movement, whereas solid lifters will not budge.
How do you set the valve lash on a hydraulic lifter?
Make sure that the dampener bolt is installed in the crankshaft, turn the engine over by hand in the direction of its normal rotation. Setting valve lash on hydraulic lifters does not require a “feeler” gauge. The process is the same for stamped steel rockers (like the ones pictured) or roller tip rocker arms.
When to set intake and exhaust valve lash?
Set the intake valve lash when the exhaust valve is beginning to open. This will put the intake lifter at the base circle which is where you want it to be. Then set the exhaust valve lash when the intake valve is about halfway down on the closing side. Be Consistent.
Can a broken lifter tear up a valve lash?
David Reher echoed the warning about checking your valve lash carefully. Too much gap between the rocker arm and valve stem can tear up a lifter. According to Reher, “A broken lifter is the most destructive component failure short of a broken connecting rod. Every time we overhaul a motor, we examine the used roller lifters very carefully.
What should the valve lash be on a camshaft?
Most camshafts will come with a cam spec card that has a recommended valve lash setting. Scott Shafiroff explained, “Your cam card isn’t the number where your car will run the best, that’s just a starting place.
