In the late 1990's, as soon as Crane realized there was one batch of improperly hardened adjusters that had been sent out (both aluminum and ductile iron rockers were involved), a recall was issued immediately to everyone that had purchased them. If we notified a distributor they should have notified their customers. Crane did not have any access to who the distributor's customers were. Some distributors apparently did not notify their customers. This was the most expensive recall in Crane's history. Parts and labor were compensated for. If a hole was "punched" in a rocker tip (ductile iron?), that certainly wouldn't leave much left of the rocker. Crane has never offered stamped steel MOPAR rockers. Crane was not "just entering" Chapter 11, they were completely shut down in a 45 minuter period in February of 2009 by an over-zealous bank officer, with no warning at all. Crane's procedure has been (and is) to request the return of any suspect parts for inspection. If there's an actual quality issue, even on used racing parts, it's addressed. Since you tossed yours, it would appear you did not return them. Regards, Chase The problem went beyond the adjusters...
Crane and then Mopar sold defective rockers, they were not hardened properly and the valve stem would punch a hole into the rocker tip..

I went through a set complained to Mopar they referred it to Crane, who was just entering bankruptcy Chapter 11....
I talked with the Crane engineering chief and he tried to blow it off with the sunshine treatment.. It was known issue that Crane hoped would go away. Very sad a major brand doesn't stand behind their products..

Getting nowhere I chucked the Cranes into the dumpster and upgraded to Harland Sharp, never looked back..

Lets clear the air from the BS...
The rockers were ductile iron made by Crane sold by Mopar. The mention hole was about 0.040" deep in multiple rockers...
Caused by inadequate hardening of the rocker arm tip, and pressure of the valve stem..

Since we have been in the car performance industry for over 30 years and have built a number of SEMA and major magazine show cars... So yes we know what we are doing..

Without boring our audience, talk to Mr.Lance he can give you the roller coaster financial details starting in 2006 with the $18 million investment by Mikronite Technologies.....

Regarding my discussion with the Crane engineering director, this took place on the floor of SEMA... I brought a sample of the bad rocker arm and was just flagging the issue, he broke out into a big tantrum. I didn't expect any reembursement but wanted them to be aware of the quality issue. After his outburst with everyone looking on I just pedalled on...

Final note..
Very sad there many of our aftermarket legacy performance parts companies are having financial issues such as Holley, McCloud, MSD, Edelbrock...
But I guess with the sales of the factory performance crate motors few individuals are building up their own engines..
Resulting in less demand for the subject performance components..

Since I've been at Crane for over 46 years, I'm more than familiar with what's happened here. I don't need to talk to Lance Harris, I lived through all of it. I do not doubt your abilities as an engine builder. I'm disappointed that someone from Crane would have treated you with a lack of concern for your issues. When you said hole, I assumed a through hole, that's obviously not the case. The ductile rocker tips were flame hardened at that time, which had been our procedure since the 1960's. We supplied ductile iron rockers to MOPAR for over 20 years. Could a few have been missed? Certainly, that's why we would like these parts returned for our inspection. In 2009 we made new tooling for all of our ductile iron rockers, and then induction hardened the tips for a more consistent product. Regarding my previous post, feel free to PM me if you have any other questions. Chase

Chase..
Many thanx for the candid response. I wish I had talked to you originally..
Anyhow this happened in 2007 or 2008 don't really remember the exact date, as mentioned I wasn't looking for reembursment or replacment as we had already addressed the subject. Just trying to make the brand aware of the quality issue, I recall there were 5 rockers out of 16 that had the hole. I couldn't figure out why I kept getting valve noise, after readjusting pre-load until I pulled the whole rocker shafts..

Have a good holiday season..
