Solid roller failed again

sorry to be a bit off here but using the F-word in posts is a bit offensive to me. even if it is spelled wrong. maybe we can be a bit more adult and use appropriate language, some peoples posts are linked to their facebook page and there are children looking at them. a little consideration with language is necessary.

Sounds to me like spring bind if you wiped out several lobes!!??

Excaliber..........You are correct on almost everything. Long periods of idle. Lots of stop lights. Idle speed way too low. My ignorance ...........That was the first time on the cam. The lash was set and checked per the cam card several times. The heads were built up after cnc port job with springs to match the cam. When the lifter failed it damaged 1 lobe slightly and 1 other lobe was scored a little. The cam builder was confident that it would be a simple fix at a fraction of the price of a new cam. Funny thing is the 2 lobes that were repaired were not damaged on this last failure. I plan on a complete tear down and dunk the block. I replaced the main and rod bearings including the oil pump on the first go around.





Thanks everyone on their input. When it is said and done my valvetrain will be all new and hoppefully BULLET PROOF. Berm

We've all heard 50/50 on the mechanical rollers living on the street. With my new motor, I've went with Isky's EZ-Roll lifters, that have a solid bearing, not needles. They did go through a few different type's of material to get where they are today, supposedly,... with no issues. I also bought a cam core from "Howards" , which sells a lot to other company's. Isky will do the grinding. I also got their "Tool Room" springs and valvetrain hardware. I'm hoping that this kind of newer,..... technology solves the street issue.

You might check with them as I have, as see what they recommend.

Excaliber- "Another problem with getting enough oil to the lifter is how modern technology (engine building, windage trays and such) keeps the oil away from the crank. So your "splash" or "oil spray" from the crank to the camshaft lobe area is greatly reduced. Thereby starving the cam/lifters."

I guess I've never thought of the windage tray, crank scraper, causing this affect. Just how much has been studied about this poentional problem ?

Very good question !
