Do you need break in oil for roller cam?
Roller cams do not need to be broken-in, nor do they need any zinc in the oil, but ALL flat tappet cams need both. Do NOT break-in your cam or engine with non-detergent oil! This is old school and these days you can’t even get good non-detergent engine oil.
Can you use roller lifters on a flat tappet cam?
It is possible to run hydraulic flat-tappet lifters on a solid flat-tappet cam, and hydraulic roller lifters on a mechanical roller cam. Running hydraulic lifters on a solid grind raises the rpm points at which peak power and torque occur compared to using solid lifters on the same solid cam.
How long does it take to break in a flat tappet cam?
20 minutes
The most critical time in the life of a flat tappet camshaft is the first 20 minutes of break in, during which time the bottoms of the tappets mate-in with the cam lobes. This is true for both hydraulic and mechanical flat tappet camshafts.
How do you break in a new engine with a roller cam?
Here are a few break-in tips from the experts:
- Wash off the rust preventative coating that is on the parts prior to installation.
- Apply a calcium-sulfonate grease instead of ZDDP before assembly.
- Use a finer micron filter during break-in.
- Prime the pump before firing the engine.
- Do not idle the engine.
Is break in oil necessary?
New cars and trucks don’t need break-in oil. The manufacturer will typically require you to drive under light-to-moderate load for a few hundred miles, then change oil. After that, you’re good to go. Racers, competitors or gearheads using a rebuilt or new crate engine, however, should use break-in oil.
How long do you run COMP cams break in oil?
The engine RPM may be varied periodically from 2000 to 2500 to direct oil splash to different areas of the camshaft. After the 30 minute break-in period, change the oil and filter to be sure all contaminants from the initial break-in period are removed from the engine.
Can you use solid roller lifters on a hydraulic roller 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 long do you run COMP Cams break in oil?
How long do you run driven break in oil?
Depending on the application, break-in oil is used for 500 – 1,000 miles, or 10-12 full heat cycles, where you allow the engine to reach full operating temperature and cool down completely between cycles. Use break-in oil only long enough to seat the engine.
