Re: Switching Head bolts
Well let me just say that you guys are giving me a big fat knot in my
stomach. :-). As I mentioned before, I did a lot of leg work in this area to find a good shop for R&R and machine and Chris thinks I paid way too much for the rebuild. Sounds like I just need to move the heck out of this state. Hopefully I have a jeep at the end of all this otherwise I'll push it into a crater somewhere or blow the thing up.

Re: Switching Head bolts
Dont lose faith Bill. Sometimes the projects that are the most trouble turn
out the best, if that makes any sense. The price for your rebuild is high compared to what we pay here, but it is probably in line with your area. I don't know what the prices are like for engine shops there, so maybe all is fine. I will stick to my guns on the fact that, for what you are paying for the job, the guy should replace the head gasket, no questions asked. Maybe having worked in an engine shop for several years building very high strung racing engines has made me more critical of what I would consider subpar work. Like I said in my previous post, your gasket MAY never fail because of changing those bolts, but think about it this way: do you really want to have to worry about it out on a trail, or worry about it everytime you start your Jeep? I would personally hate to get stranded somewhere in BFE because of a failure that could have easily been prevented with a simple gasket replacement.

Like I said in my previous post, your gasket MAY never fail because of changing those bolts, but think about it this way: do you really want to have to worry about it out on a trail, or worry about it everytime you start your Jeep? I would personally hate to get stranded somewhere in BFE because of a failure that could have easily been prevented with a simple gasket replacement.

Re: Switching Head bolts
Dont lose faith Bill. Sometimes the projects that are the most trouble turn
out the best, if that makes any sense. The price for your rebuild is high compared to what we pay here, but it is probably in line with your area. I don't know what the prices are like for engine shops there, so maybe all is fine. I will stick to my guns on the fact that, for what you are paying for the job, the guy should replace the head gasket, no questions asked. Maybe having worked in an engine shop for several years building very high strung racing engines has made me more critical of what I would consider subpar work. Like I said in my previous post, your gasket MAY never fail because of changing those bolts, but think about it this way: do you really want to have to worry about it out on a trail, or worry about it everytime you start your Jeep? I would personally hate to get stranded somewhere in BFE because of a failure that could have easily been prevented with a simple gasket replacement.

Re: Switching Head bolts
Thanks Chris,
It's just a bit of head spinning going on. While working to get this done I also have my wife chirping in the background about spending money on this jeep. Then the R&R guy calls me about the head bolt and says he can't find a place to mount the Crankshaft Position Sensor after I gave him instructions and pictures. I'll be glad when this crap is over for sure. Bill "c" <c@me.org> wrote in message news:%3Ync.52725$u_4.9998@twister.rdc-kc.rr.com... > Dont lose faith Bill.

Re: Switching Head bolts
Thanks Chris,
It's just a bit of head spinning going on. While working to get this done I also have my wife chirping in the background about spending money on this jeep. Then the R&R guy calls me about the head bolt and says he can't find a place to mount the Crankshaft Position Sensor after I gave him instructions and pictures.
