Angry Lifter Dead... Pushrod bent.. Rocker arm shattered..

I think the source of this was too much RPM (7k) for too long (a bunch of donuts)..

I have 15 comp R lifters.. I don't have the money for morels right now.. should I buy a 16th or just buy another stocker?

As for the time being, I took the spark plug wire and fuel injector harness off that cyl (Cyl 3) and just put a new rocker arm in there. Autozone was closed, so I couldn't get a new pushrod.. but I don't think it matters much, because the lifter isn't working anyway (the pushrod isn't moving).

I can tell that the lifter was collapsed because the pushrod was sitting just level with the guideplate when I took the shattered rocker off. When I put the pushrod back in, it sat maybe 2cm higher, but when I pushed down a little, it went back to being level with the guideplate and didn't come back up.

Anyway, if anyone has a single comp R lifter they want to sell, PM me..

And, if anyone has any opinions, lemme know.

So, what metal is floating around in your engine? I would not be running it until I found out.

So you suggest I also change my oil?

No metal from the rocker.. we found all the pieces.. I'm not sure about the lifter.. I don't know what happens when they collapse..

Definitely get that oil out of there. Either buy one Comp R or 16 different lifters.

I'd pickup a set of lightly used stockers and save up for the morels.

Re: Lifter Dead... Pushrod bent.. Rocker arm shattered..

I had already driven the 250 miles home [after noticing the power loss and valvetrain noise] by the time that I posted this

I thought it was just a rocker at the time, so I figured the worst that would happen would be a bent pushrod.. I guess I was wrong..

It was too late at night to stop anywhere though, and too cold to check it out on the side of the road (esp since I couldn't do anything with no parts)

Anyway, hopefully there won't be any pieces of the lifter in the oil...

Re: Lifter Dead... Pushrod bent.. Rocker arm shattered..

I may have missed this in the previous posts. If so sorry but. If you broke a rocker, bent a push rod and ruined a lifter it would seem to me the common denominator to all those is a sticky valve. You may want to investigate the valve and the guide before you go throwing more parts at it.

Just my .02

what does turn the lifter mean?

Do you mean break the lobe off the cam/grind down the lobe on the cam?

Should I consider doing a new cam at the same time as the lifters?

It means the lifter physically turning to where the roller bearing is not set correctly on the cam lobe.
As already stated when something like that happens it is usually caused by mechanical contact... either sticky valve or even smacking a valve into a piston. Either way the heads should come off to see if there is any more damage. If you don't do it now you may run into a heap of problems shortly after getting back together again.
BTW... stop w/ the 7Krpm stuff. It ain't benefiting you at all unless you are running cam/heads to accommodate.
