ChewinBolts

Update: Because I know how annoying it is to find forum threads relevant to what I am looking for & see no resolution, here is what has transpired since I last posted. I looked at LKQ, found an engine in N.C. that claimed to have 44k, could have had it shipped to me for just under $2k. I almost did it but I did some research & watched some YouTubes by people who bought junkyard engines whom had less than desirable results. I called the local machine shops, both of them told me that they believe that they could do it, as long as the previous heli-coil repair didn’t result in losing too much “meat” (I wanted them to insert them all). We had been driving my mothers 23 y.o. Chevy. So I loaded the block up & headed for the machine shop! Literally just as we were about to turn in, my mother’s transmission went out & the Chevy lost all “go”. It was dead. $200 tow later.. I was frustrated. We went to a local car lot & she is now the new owner of a 2015 Cherokee 3.2 v6. ? So, the engine is in a box on our living room floor. I have not given up, far from it! But we had to have reliable transportation. I’ll be taking the engine to the shop early next week & will update with pictures if they’re able to do it.

Hello! My name is JD & I am new to this forum. I searched it out because I am currently rebuilding my wife's 2009 2.4 liter engine. It was knocking, shuddering & doing some odd things so I stripped it down entirely. I found the rod bearings were severely worn, the head gasket was leaking oil to the outside, the main bearings had some wear, the cylinder walls have a bit of pitting, one of the camshaft cap bolts is broken & one is stripped, there was half a drill bit stuck in the crank case & all of the cylinders have burnt oil caked on the pistons/valves. I'm replacing all of the bearings, the entire head & piston rings. My problem is.. someone has had the head off of this engine before. Half of the holes are heli-coiled. They're deep head bolts so it's not easy to get to the threads where they need to be, so the previous person heli-coiled the top of the holes. I'm assumed it overheated in the past maybe? Idk. It seems to have worked.. half-arse. The head gasket was leaking oil to the outside of the block. I have one hole that is not heli-coiled & is stripped out. I've done some research & found that there's a tool called "NS300L" that's supposed to be for inserting these engines. I also found the Time-Sert 2200, but the Chrysler isn't listed as one of the engines it does, so I am not sure if it's long enough or not. My question is.. has anyone run in to stripped head bolt holes? If so, how did you fix it? Do you think a machine shop would do it? And, would you replace the head bolts themselves? Also, would you attempt to remove the heli-coils & insert the bottoms of all of them, if possible? I'm gonna call the machine shops tomorrow. I apologize if there's already a thread but I did look & I couldn't find one. Thank you!
