Time for a new Heater Core - how much?

From : Annonymous

Q: john learn to read. i said in one instance the rented forklift trapped air caused a bearing problemwhich indicates it can happen elsewhere. i also stated that the perfect system only exists in text books. -- budd cochran warning!!! poster still believes that intelligence logic common sense courtesy and religious beliefs are still important in our society and might include them in his posts. yes i disagree that air in the system when heated will apply more pressure to the to bearing. as i stated the system is open to the reservoir when the pedal is in the released position therefore any pressure buildup would merely push the fluid back into the reservoir rather than apply more pressure to the to bearing. thats terrific in a perfect world. what happens if the pedal doesnt fully release back pedaling again your claim was and has been that entrapped air alone will cause the to bearing to apply even in an otherwise normal system. a failure of the pedal to release is an abnormal condition. budd is claiming that entrapped air alone caused the to to apply and that a simple bleeding cured the problem. if the pedal wasnt in the full up position and bleeding was used to cure the problem the problem would recur; budd claims it didnt. .

are you sure you are reaching the cam if a cam bearing moved just a few degrees no oil to the heads. drilled passages in the cam journals regulate the flow but have to line up with holes in the bearings. is the cam getting oil has the engine ever been rebuilt could it be the bearings were installed wrong btw amc v-8 lifters are the same diameter and hollow pushrods can be made up but theres no hole in the pushrod socket on the rocker iirc. -- budd cochran on wed 02 nov 2005 001306 gmt tbone tbonenospam@nc.rr.com wrote that would probably work and that would be a huge mistake. if the heads have been runny dry long enough to trash the rockers i would say that the seals and guides are pretty much toast as well. re-introducing oil flow at this time would probably result in turning the engine into a killer smoke bomb and make the vehicle undrivable. i would follow budds advice and look into a rebuild or if you do try this method have a set of rebuilt heads and gaskets ready as you may need them really soon. hey its worth a try isnt it the engine will be trash if oiling is not restored and there is a chance restoring oiling will solve the problem without causing it to smoke. would definitely not be the first one. i had a 65 rambler with the same problem that i figured was not worth dissassembling to fix so i fed oil to the rocker shaft with a piece of brake tube connected to a t at the oil pressure switch. shut up the squeaky rockers and no oil consumption problems. i made that mistake with my 62 ford falcon. that engine was notorious for it plugging up the oil feed to the head and when i got this one it was like that for a while. the rockers were so worn out from it they could barely open the valves. at first i just cranked back down on the adjusters to correct the valve lash and would pour stp over the rocker assembly once a week. since there was no oil flow there was no need to worry about the valve cover gasket so it was easy to do and the engine ran fine. after i gave the car to my father he decided to see if he could clear the clogged port and unfortunately we were successful. not only was the rocker assembly well lubricated there were no surviving mosquitoes for miles and the vehicle became close to useless. i would suggest that if the op wants to try this method he first remove the valve covers and with the engine running pour some hot oil over those rocker assemblies and see if it smokes. if not try beekeeps method to clear it and if successful just replace the rocker assembly in each head. if it does then he could still attempt this and if successful replace the heads. either way it will save money over a complete rebuild but the main problem would be that the engine could still have other problems due to possible neglect. -- if at first you dont succeed youre not cut out for skydiving is it possible to get push rods and lifters for this engine with the oil holes in them the heads are off getting a valve job done now. i can spin the oil pump with a screw driver buy hand and i get oil to the lifters. if i push all the lifters up in there bores i can feel the pump build pressure but nothing comes out of the holes to the heads. i can stick a wire in the holes and it goes all the way to the cam. .

i have an 04 dodge quad cab with the fold down drink holders. i had mounted a 2-way radio to the face of it and now my department is going to digital 2-way radios making mine obsolete. i am thinking of replacing the door part while i can find the parts rather than wait 5-10 years and then trying to find the door. is this a big deal to change and does anyone know of a good place besides the dealership to get this part as im sure theyll be higher than hell for this part hp .

i dont know if the engine has ever been rebuilt but my rockers do have oil holes in the socket. are you sure you are reaching the cam if a cam bearing moved just a few degrees no oil to the heads. drilled passages in the cam journals regulate the flow but have to line up with holes in the bearings. is the cam getting oil has the engine ever been rebuilt could it be the bearings were installed wrong btw amc v-8 lifters are the same diameter and hollow pushrods can be made up but theres no hole in the pushrod socket on the rocker iirc. -- budd cochran on wed 02 nov 2005 001306 gmt tbone tbonenospam@nc.rr.com wrote that would probably work and that would be a huge mistake. if the heads have been runny dry long enough to trash the rockers i would say that the seals and guides are pretty much toast as well. re-introducing oil flow at this time would probably result in turning the engine into a killer smoke bomb and make the vehicle undrivable. i would follow budds advice and look into a rebuild or if you do try this method have a set of rebuilt heads and gaskets ready as you may need them really soon. hey its worth a try isnt it the engine will be trash if oiling is not restored and there is a chance restoring oiling will solve the problem without causing it to smoke. would definitely not be the first one. i had a 65 rambler with the same problem that i figured was not worth dissassembling to fix so i fed oil to the rocker shaft with a piece of brake tube connected to a t at the oil pressure switch. shut up the squeaky rockers and no oil consumption problems. i made that mistake with my 62 ford falcon. that engine was notorious for it plugging up the oil feed to the head and when i got this one it was like that for a while. the rockers were so worn out from it they could barely open the valves. at first i just cranked back down on the adjusters to correct the valve lash and would pour stp over the rocker assembly once a week. since there was no oil flow there was no need to worry about the valve cover gasket so it was easy to do and the engine ran fine. after i gave the car to my father he decided to see if he could clear the clogged port and unfortunately we were successful. not only was the rocker assembly well lubricated there were no surviving mosquitoes for miles and the vehicle became close to useless. i would suggest that if the op wants to try this method he first remove the valve covers and with the engine running pour some hot oil over those rocker assemblies and see if it smokes. if not try beekeeps method to clear it and if successful just replace the rocker assembly in each head. if it does then he could still attempt this and if successful replace the heads. either way it will save money over a complete rebuild but the main problem would be that the engine could still have other problems due to possible neglect. -- if at first you dont succeed youre not cut out for skydiving is it possible to get push rods and lifters for this engine with the oil holes in them the heads are off getting a valve job done now. i can spin the oil pump with a screw driver buy hand and i get oil to the lifters. if i push all the lifters up in there bores i can feel the pump build pressure but nothing comes out of the holes to the heads. i can stick a wire in the holes and it goes all the way to the cam. .
