just wondering what it would take time ,material, money wise what it would take to rebuild a 12 valve.. i found one online for a good price the only downfall is it has 270K on the odometer. im looking to do a swap in my 97 f-250 and would like to put something a little more fresh in it.. thanks for any advice

 

are you looking to rebuild a currently poseesed 12v? if so your looking at a minumum of $2000 for the rebuild top to bottom, just did mine last month

 

270,000 miles aint !a cummins is just broke in at those miles.if that motor was well taken care of and if you take care of it that motor could last another 300,000 miles.i have a friend who has one with over 500,000 and all he's done is put an alternator on it!he said he thought about putting main bearings in it to bring the oil pressure up to where it was!

 

i have 260,000 on my 12V and the only stuff i have replaced are dodge parts if they took care of the truck just change the oil!

 

i have 200k on my 97. only problems i have had is the kdp fell out. My work truck is a 96 12v with 300k and only had lil basic maintenance thing nothing major

 

i have 200k on mine,runs like new!

 

i had almost 300,000 and ran great untill it over heated

 

wouldnt take very long to rebuild

 

I had 330k on mine and rebuilt it, it didn't need it. but given the situation I decided to go ahead and do it.. It still had the factory cross hatching marks visible in all 6 cylinder walls. I was shocked. If it were me i'd put main bearings in it, and leave the top end alone. But that's just my 2 pennys... Anyways to address your question. I got a dealer price on a complete kit pistons rings gaskets bearings had the head surfaced ond magna fluxed. and all total I think it cost just over 2k like 2200 or something like that. Hope this helps and good luck with the swap!

 

cool thanks guys for all the input
