# 1- a 2021 with 22K is there warranty still there? #2 - as you stated a ok till grease job; what did you use for grease based on the temp in chicago ? wrong heavy grease causing the throw out to drag .

Based on Your post, is it possible to connect with a museum type organization that can hold/ display this truck till many details You must have can be put in order. I don't think anyone on this forum would want to see any negative happen to You or the vehicle. scammers are always on the prowl for victims. as you stated, your knowledge is limited in terms of the truck with sentiment / emotion making a sell way more difficult. if it were put on display, you can see it and others will appreciate it . then when the moment is right (never actually) it can be sold to the proper new owner.

Also Sorry for Your loss. i wouldn't want to be in your position, TJC is correct in his statement. value is what someone is willing to pay. when an item has personal ,emotional sentiment how can a dollar value seem fair. after my Father passed and the "clean up" started, a $10.00 item was worth $$$$.yet reality it value was $5.00. tough call for many who have to go through it.

the red gauge is cycling due to the air leak. far as the vent leak i'll take a shot at the solenoid is malfunctioning . not to knowledgeable on the new truck systems. when shut off the electrical system for ac should be off; fan still works, i'd say system live and shouldn't be. to cycle the system must be large leak.

updates are always a positive. one thing i've noticed on this site is with so much helpful information being shared ; rarely see updated messages letting the responders know results of their help.

breaking ring wasn't really the issue ; melting pistons was

more detail sure does make a difference on diagnostic ideas. Thank you for update. that's sure is alot of $$$$$ into that engine.

new generation can't use a tuna can, new cans are easy open only on one end. have to find an app for instructions on removal of opposite end.hopfully instructions say empty can first. it's a mack might be better to use a dog food can!!LOL

to break after 24k possible mechanical failure to break again after 3k ; install failure. were new rings put in second time or did someone pick the "best of the old" and reinstall. obvious when rings break ;; compression loss, oil blowby etc, who/ why broken rings determined .

where did he go ??? we are waiting for answers

we are on the same page on this one. i was writing as you were posting. what was being used for a ring compressor; not granny's tuna fish can

another situation not being there to see / know all the facts. what type of truck are we dealing with;; older fire truck with only 24k miles . older road truck having a rebuild== why was it rebuilt ?WHO did the work,what parts were reused? etc... not degrading anyones work, just don't know what we are up against.. I like the part " any OLD mechanics" . YA someones looking for me 😀LOL

are you saying the engine was done and rings broke 24k miles later , rings replaced again then broke after 27k (51k miles)or broke again after 3k mile , total engine miles 27k since rebuild?

if only the younger generation could understand. we weren't careless just ambitious , sounds better. i tell my 23 yr old grandson all the time practice safety . hope over 50 have meaning to it. for me over70 and doing the wrenches FOR 50 yrs i'm reminded every morning trying to get out of bed of my yrs gone by "ambitions"

definitely ;; every job has the ==what if factor == for me. swapped out complete tandem suspension on a 53ft trailer last week. outside , soft ground , NO jacks. lowered the landing gear brought nose to ground. blocked up the ICC bar with 2ft dia x 2ft tall logs ,4x4 on the ground under the logs. cranked landing gear back up highest point .raising the entire trailer. pulled suspension out (short version) install newer suspension, point is the "what if factor" was there every minute. unit was blocked more then it had to be . job would have been alot better in the shop on concrete floor with air jacks ; wasn't possible. having a number of jacks for different projects AND common sense makes all the difference in the "what if factor" and safety.

if the jack purchase is based on $$$ highly recommend a good jack stand to go with it. hate to see someone buy a cheaper jack figuring " if it picked up the front end i can jack up the back and pull tires" etc. be under it doing brakes or what ever and have the jack give way. seems with old age the first thing i consider lately when doing a project is :: how am i going to get hurt. same as buying tools in the past, some projects will do well with a cheaper brand . then there are the jobs that require a better quality (snap-on or so) tool

A clunking/ vibration in front end !!! i don't think " how long can i drive it " would be a proper question. more like i need a jack NOW , who's got one. i would be buying a jack before buying lunch. might go with a vibration ; possible out of balance tire. clucking no way

don't know about today, Toce bros were always a pleasure to deal with when Sonny was there. they had one service worker called "evil" . never saw anyone work as hard as him. hot blazing sunny day he pulled 8 tires off unit, dismounted old / remounted new ;; reinstalled on tractor out side, didn't want to tie up load out bay which would have put him under cover in some shade.

other side of the coin ; might not be a dumb question, but dumb not to ask when looking for answers. for some real dumb questions : check out the questions "people "ask on articles from amazon! 😄 some are as good as the pictures from walmart..LOL

some one has an interest in furthering their knowledge ,it's not to be considered dumb questions.

got the yr '71 see it in topic title , could be alt or gen. i question power source only due to a gen will make its own power an alt needs power to make power.

If there is a S/P switch on your unit, doubt it is between seats (more in B models). unit has one ; which i'm starting to think not it will be in the battery box. quick look at the cables will tell if a S/p is there. cables are short going from battery box to frame for ground it's 12 v. what yr is truck ,is it alt or gen?

working at Mack yrs back, I got in big trouble with parts room manager. new kid at the parts counter. I took a worn 3/8 bolt to the counter and asked the kid for a new crankshaft bolt, it looked just like a crankshaft worn so bad, he searched then asked the manager. manager came to counter and let me know the kids got other things to do ! we didn't get along in the first place.

what are these apps on the phone everyone talks about. i keep looking at the black and white rotary phone in my house and only have the 9 +0 numbers LOL.

i know i'm always thinking in "old terms" , no one asked if the fuel filters were changed recently. low voltage doesn't sound right . good pressure does n't mean its good fuel if the filters are full of water .
