"LETTING OTHERS DO THE WORK FOR YOU"

I HAD AN A.S.E. MECHANIC PUT MY NEW CAM IN MY VAN A MONTH AGO. BUT JUST TODAY AFTER DOING THE OIL CHANGE, I FOUND BRASS OR BRONZE SHAVINGS IN THE OIL. I KNOW I BOUGHT A CAM, LIFTER'S, LUBE, BUT I DIDN'T KNOW ABOUT CAM BEARINGS IN SUCH, TO HAVE THE CAM PROPERLY INSTALLED. I LOOKED AT THE RECEIPTS AND NO MENTION OF CAM BEARINGS AND SUCH! HEY GUYS HELP ME, I DONT KNOW HOW TO CHECK THAT STUFF LIKE PULLIN, THE CAM OUT OR LOOKING UNDER THE INTAKE FOR DAMAGE OR EVEN PULLING THE DISTRIBUTOR OUT TO CHECK THE SHAFT AND GEAR.

First of all, lose the caps.

If all you had done was a cam install, chances are the cam bearings didn't get changed, they don't always need replacement. I would venture the shavings you found were from the distributor gear.

Moving this to basics.

You don't need to type in all caps.

Bronze could come from a bronze distributor gear, sometimes used w/roller cams or cams made from steel. Unneeded when using a normal iron flat tappet-type cam, or w/many street hydraulic roller cams.

Otherwise what you might be seeing is iron or aluminum w/oil on it- which looks "bronze" until the oil is removed.

The cam and lifters need to be broken in to each other by running the engine at varying RPM, not lower than 2000 RPM (NO idling!) for at least 15-20 minutes, to avoid immediate failure of the lifters and cam lobes. Was a proper break-in done?

There should have been break in lube applied to the lifters and lobes and an oil additive such as ZDDPlus added to the motor oil to facilitate a proper break in as well.

If the cam lobes and lifters are wearing away, the engine will soon develop a miss, will start running poorly and start to have a noisy valve train that will not adjust out.

Are you experiencing any drivabilty problems, ticking, knocking, since the cam was installed?

Why did you have the cam changed?

What type of cam did you have installed?

"My van and cam story"

I had the engine rebuit in 07' but didnt put a good cam in that i wanted! So, the cam i put in is a PBR i guess by Comp, a .275/.278 (.050@) .435/.455 cam. it might seem a little big, but i asked a machinist from my local Napa, what type a cam i could use. BUT he told me about this cam that i suspect to be in a 350/350hp. engine! Well, i dont know what lunging is, but when im driving her, and if i step in it, it lunges forward, but yet it feels like something is holding it back, like i need a shift kit and/or a stall converter! i have headers, dual exhaust, H.E.I., a performer air gap intake(idle-5500), and the cam. Now i know that the cam I have has a higher RPM start than idle but i dont know where. But this lunging is only i guess when the secondaries kick in. i dont stay in very long at all because it doest feel right. But besides that, it feels like it has more power, and drinks a little more gas.LOL! but i plan to change out the jets to something smaller, out of my Edelbrock Thunder Series 1805 (650 cfm manual chock, four barrel).

"The van and cam story" 2

Son of a gun! next time look in the oil drain pan before you use it! My roommate was using it before me, and put drill shavings in there. tinkering around with some stuff with his boat motor. LOL! I AM HAPPY!!! but i still think i need a stall converter and a shift kit for the tranny. What do you think guys???

cam wear!! and distrbutor wear!!!!

I would take it back to the shop that did the work and let them know what you found. then ask if they would pull the distributor and check for wear on both the cam drive gear and distributor more than likely you will find some signs or wear
