In Heating The Clinder On A 58 To Remove Stuck Nipples,can You Over Heat It?mike,you Are Aware Of My Problem With These Dern Nipples!well,i Finally Got Them All Out With Some Help From A Buddy But We Really Had To Throw The Heat To The Cylinders.do You Think Its Possible To Over Heat Them With A Tourch,which Is What We Used.i Had 4 Cylinders And All Had Stuck Nipples.in My Defense These Were Bought Second Hand So The Damage Was Already Done Before I Got Them.on My Stainless 58 I Put A Little Bit Of Choke Tube Lube On The Threads And I Have Never Had A Problem.but They All Are Out Now And I Just Have To Buy New Ones Now.i Just Hope We Didnt Get These Cylinders Too Hot And Cause Any Unseen Damage Like The Metal Being Weak In These Areas Where We Heated Them.
