Cracks in an aluminum head or block, on the other hand, are much more difficult to repair by pinning because aluminum is a softer metal than cast iron so the pins and plugs can't achieve as much “bite” as they do in an iron casting.
May 17, 2009 Apparently there are no threads left in the block for one of the head bolts. I found out the hard way when torquing the head down. The head stud was tightening down and then broke free all of a sudden so I pulled it out and all of the block threads were still attached to the head stud. So I need to repair this before I can finish assembling the ...
May 25, 2015 As the title suggests, my engine build has come to a screeching halt when the very last head bolt yanked the threads out of the block.

The kit comes with the unique tap, insert tool, and six thread inserts.

I bought some ARP head studs, which didn't quite fit. I don't have a thread micrometer, so I can't say exactly how oversized they were, but I wasn't going to get them in without a breaker bar (even then it's a maybe). So I took a little off with a die and then installed the studs with a little oil. The block is aluminum.

Jan 08, 2008 By oiling the threads, the reading on the torque wrench will be incorrect.In other word you would have over torqued the bolts. looking at my pocket ref: 5/16-18 bolt,raw steel, no lube, 29 foot pounds torque. SAE 40 wt oil, 17 foot pounds (41%). Now your best option for repair is to helicoil the striped holes.

Dec 11, 2010 This thread is from 2009, so it might be a better idea to create a new thread for your problem, but FWIW, I wound-up helicoiling about 4 bolt holes in the block, but then one of the helicoils actually started pulling up when I began torqueing the heads down! I ended-up selling the block and rotating assy on eBay as-is and put another motor in ...
Feb 01, 2007 The problem with anti-sieze on small bolts in bare aluminum is: It acts like a lubricant, and makes the bolt very easy to turn, and can lead to a stripped bolt hole during tightening. I would really consider some kind of thread

Feb 06, 2018 As mentioned in an earlier thread I removed one of my engine heads and during that process one of the bolts pulled the threads out of the hole (See attached photo).

Sep 27, 2011 I was in the process of installing front tip-over bars today on my old Concours. I've had these bars laying around since January. As I was tightening the bottom left mounting bracket (the bolt goes into the radiator mounting bracket), with the torque wrench set at 35 ft-lbs (instructions for tip over bars say 30-40), of course, the aluminum engine block threads got

Oct 30, 2006 The stripped thread is in the aluminum block. It is the hole that holds the lower front cylinder head stud. The stud would not take the 20 NM + 90 degrees + 90 degrees torque. So, the stud stripped its hole threads an came out with ~1/2" of aluminum clogging the end of its thread grip, leaving the upper ~1/2" of thread clean.
Nov 17, 2009 So, I ordered a set of the Fel Pro 1003 gaskets an ARP head bolt set (with the hardened washers - the builder did not use washers when he built the engine with aluminum heads, I thought that was something that was supposed to be done {the bolt set that he used cost him $17, so I thought it was best to order the proper bolts}).
