When should I change oil after Cam break in?

When should I change oil after Cam break in?

Change Oil Often After using a break-in oil, you should change your oil at 50 miles, 500 miles, and 1,500 miles. Again, at 4,000 miles or so, it’s fine to switch to a synthetic oil if you choose.

How do you break in a new flat tappet cam?

Procedure

1. Install the Camshaft.
2. Set the Valve Lash or Preload as recommended by the manufacturer.
3. Prime the Oiling System.
4. Set the Initial Ignition Timing.
5. For carbureted engines, make sure fuel bowls are full and any air is bled from the fuel lines.
6. Start the engine and immediately raise rpm to 3,000.

Why do you need to break in a camshaft?

Perhaps the most important step in the break-in process is to bring the engine immediately up to a minimum of 2,500 rpm or more. This is vital because most V8 pushrod engine camshafts are not pressure-lubed. A higher engine speed for the first 20 minutes ensures plenty of oil reaches the camshaft.

How long should you break in a cam?

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 long does it take to break-in a new camshaft?

This process should only take about five minutes but can sometimes take longer. A big-block Chevy will take much longer to pump oil to all the rocker arms-perhaps as long as 20 minutes. Now replace the distributor by positioning the engine at No.

How long do you leave break-in oil?

In general, run the engine under light-to-moderate loads for about 500 miles. Again, that duration is a rule of thumb, but break in shouldn’t exceed 1,000 miles. Then, drain the break-in oil, install the synthetic oil of your choice and commence driving.

How much zinc does it take to break a cam?

Current API SM and SN oil limit ZDDP (zinc and phosphorous) levels to 800 ppm. While ZDDP break-in level recommendations for flat-tappet camshafts vary widely, it appears that concentrations of around 1,500 ppm or above are appropriate, and as you can see from our testing, most of the break-in oils achieve that level.

What causes camshaft to break?

Mechanical Interference When moving parts are not given adequate clearance, things can start to break. Damage can result from excessive heat build-up, limited range of motion, or parts crashing into each other.

How long does it take to break in a new camshaft?

What is the camshaft break-in process?

The first, and most crucial step to the camshaft break-in process is to drain any oil in the engine, spin on a new oil filter, and fill the engine with a break-in oil containing high levels of zinc and phosphorous.

Can I use a higher ratio rocker arm with Edelbrock camshafts?

Edelbrock recommends stock ratio rocker arms to be used with Edelbrock camshafts. The use of higher ratio rocker arms will change the listed cam specs. Another problem with a higher ratio rocker arm is the added load on the camshaft lobe.

Should ededelbrock lifters be pumped up before installation?

Edelbrock lifters are an anti-pump lifter design, these lifters should not be pumped up, primed, or soaked in oil. If the lifters get pumped up before the installation, the lifters will become solid and you will not be able to adjust the lifter preload, the valve will just be opened when valve adjustment is performed.
