Adjusting solid lifters (also known as mechanical lifters) without a cam card can be a bit challenging, but it’s definitely possible with careful procedures. The cam card provides specific information about the camshaft’s specifications, such as lift, duration, and lobe separation angles, which can be helpful for setting up the valve lash correctly.
Without the cam card, you’ll need to rely on some general guidelines and practices.
Here’s how you can do it:
How to Adjust Solid Lifters Without Cam Card
1. Gather Basic Information:
Before you begin, gather as much information as you can about the engine and camshaft. If you know the engine type and any details about the camshaft, such as the brand or model, this can help you find general specifications that might apply.
2. Find TDC (Top Dead Center):
Identify the top dead center (TDC) for the cylinder you’re working on. You can do this by using a piston stop or by watching the motion of the valve as you slowly rotate the engine by hand. Make sure you’re on the compression stroke, not the exhaust stroke.
3. Adjust Valve Lash:
Valve lash is the clearance between the lifter and the valve stem when the lifter is on the base circle of the cam lobe. A common rule of thumb is to set the valve lash to about 0.020 inches (0.5 mm) for intake valves and 0.022 inches (0.55 mm) for exhaust valves. These are approximate values and can vary depending on the engine and camshaft characteristics.
4. Adjust One Cylinder at a Time:
Work on one cylinder at a time to prevent confusion. Rotate the engine until the lifter for the cylinder you’re working on is on the base circle of the camshaft.
5. Adjusting the Valve Lash:
To adjust the valve lash, follow these steps:
- Loosen the lock nut on the rocker arm.
- Use a feeler gauge to measure the clearance between the lifter and the valve stem.
- If the clearance is too tight, loosen the lock nut a bit more and use a wrench to adjust the rocker arm stud. This will increase the clearance.
- If the clearance is too loose, tighten the lock nut and adjust the rocker arm stud to decrease the clearance.
- Once you have the correct clearance, hold the stud in place and tighten the lock nut.
6. Recheck and Double-Check:
After making the adjustment, double-check the valve lash using the feeler gauge to ensure it’s within the desired range. A bit of trial and error might be necessary to get it just right.
7. Repeat for Other Cylinders:
Repeat this process for each cylinder, ensuring that you’re adjusting the valves while the corresponding lifter is on the base circle of the cam lobe.
Keep in mind that these are general guidelines, and the actual valve lash specifications can vary based on the engine and camshaft. If possible, consult with experienced mechanics or engine builders who might have more insight into common practices for your specific engine. Additionally, consider investing in a camshaft degree wheel and a dial indicator to help you get more accurate results without a cam card.

How Do You Adjust Valves on Solid Lifters?
When adjusting the valves on solid lifters, it is important to ensure that the camshaft lobe has been properly degreed and installed. This will help make sure that when the valvetrain components are in motion, all of the parts remain within their designed tolerances. Once you have made sure your camshaft is correctly set up, you can begin adjusting your valves.
The first step is to check each valve’s clearances with a feeler gauge while turning over the crankshaft by hand. If any of them fall outside of what’s specified in your engine manual, then they must be adjusted accordingly. To do this, adjusters need to be screwed out or in until they reach their desired settings as indicated by a gap measurement taken with a feeler gauge.
Be careful not to overtighten these adjusters as doing so could cause permanent damage and lead to premature wear down of all related components such as valve springs and rocker arms. Once everything has been checked for accuracy and tightened down properly, start up your engine and take note if there are any strange noises coming from the area before giving it full throttle power runs around town or on track days!
Do You Have to Adjust Solid Lifters?
Adjusting solid lifters is an important part of vehicle maintenance for many cars. Solid lifters are found in most engines and need regular adjustment to ensure that your engine is running as efficiently and smoothly as possible. The process of adjusting these lifters involves several steps, including checking the valve clearance, lubricating the rocker arms, ensuring that the valves are properly seated and setting the proper tension on the pushrods.
It’s important to note that this process should only be done by a professional mechanic who has experience with this type of work; attempting to do it yourself could result in costly damage or even engine failure. Additionally, if you’re unsure about any part of this procedure then it’s best to consult with a qualified technician before proceeding. Taking care of your car’s solid lifters will help keep your engine running optimally for years down the road – so don’t forget to get them adjusted regularly!
Do You Adjust Valves at Top Dead Center?
When it comes to adjusting valves at top dead center, the answer is yes. Top dead center (TDC) is the point on an engine’s crankshaft when all of its pistons are at their highest position in their respective cylinders and no further upward movement is possible. During this time, it’s necessary to adjust each valve actuator or rocker arm to ensure that each valve has a proper lift as well as close properly without any restriction.
This process must be done accurately with precision tools such as feeler gauges and torque wrenches so that maximum efficiency can be achieved from your engine. Adjusting valves during TDC allows for optimum fuel burn and combustion which leads to better power output, improved performance, and increased durability over time. Making sure your valves are adjusted correctly should also help reduce emissions while helping you get the most out of every mile you drive!
How Do You Set a Valve Lash on a Solid Cam?
Valve lash is an important part of any engine’s performance. Without proper valve lash adjustment, you can have excessive valve noise and even catastrophic engine failure. On a solid cam engine, the process of adjusting valve lash is relatively simple as long as you know what to look for and how to do it correctly.
The first step in setting valve lash on a solid cam engine is to identify which type of valves are used in your vehicle. Depending on the make and model, they may be hydraulic or mechanical lifters that require different measurements when setting the proper clearance between them and the camshaft lobe surface.
Once this has been determined, remove each rocker arm from its mounting point one at a time so that you can inspect it for wear or damage before proceeding with any adjustments.
Once all rockers have been inspected for damage, use a feeler gauge to measure the gap between each roller tip and its corresponding lobe on the camshaft surface. Take note of these measurements so that adjustments can be made accordingly when re-installing them back onto their mountings points later on during assembly.
After all readings have been taken note off proceed by loosening up each nut holding down each rocker arm while being careful not to move anything else around while doing so; once loose enough adjust each individual gap until it reaches its desired measurement before tightening everything back down again securely in place with a wrench or socket set depending on size requirements specified in your vehicle service manual.
