2013 Volvo D13 fuel injector issues

Hey guys right of the bat, If you want to skip to the question I will divide it between how I ended up with this truck and my issue that I hope some of you can answer.
So i took the route of an owner op. And I purchased a 2013 volvo 780 D13. I kinda took a risk it because it was priced good, had very low miles/hours for its year, at 420k miles for only $35,000. The truck had absolutely brand new Michelin tires and new alco wheels all around. New shock absorbers and t arms. Ran perfectly fine, no engine codes, good engine idle, pulled good for a 425hp, so no syptoms. So after I made a purchase 2 months down the road I noticed the oil slightly rising, so I asked around and people recommended an oil analysis. When I sent it out it came back with 14% fuel in oil that I just recently changed. I sent out the old oil as well and it had 28% fuel in oil. I took it to a shop and here is what they said
---------------------------------------

I have 1 bad fuel injector, #2 and it is putting fuel in the oil. Now with further inspection they noted I will need to replace my camshaft and rockers because the oil/fuel chewed it up. Ive done several engine rebuilds in car engi e and my personal opinion tells me my cam is not as bad as he is saying. My question is, how many of you guys ran on a cam that was chewed up but truck ran and pulled good. I would like to run on this cam until I save up some money, they quoted me $12k for parts and labor. I will still do the fuel injectors which is like a $4,600 repair but to clarify the question are there guys out there that ran on a chewed up cam and had either issues or success?

 

I'm not sure, possibly misfire. I'm just trying to see if anyone ran there truck with a chewed up cam shaft and how long it lasted before they got issues.

 

Wow i thought 12k was allot. yea I would not hesitate it's the funds that are not letting me do it. If done seperate the labor for cam work is 2700 and 950 for injectors. If together then they said injectors will cost $500 to replace, cam price stays the same. so it's not that big of a difference. I was hoping I can run maybe 40k miles and then change the cam. That way I have funds and dont have to loan money.

 

I really appreciate you guys tuning in, and helping me decide. I think you guys are right, its really not worth running this damaged cam and rockers. The route im going is actually to find a good condition cam and rocker set and run it until i can save up money for new parts. I just found a deal on all the rockers: Dealer price was $4900 for all rockers, i picked up a used set in good condition for $250. If i can find a cam for under 1k used this rebuild will cost me $6200 instead of $12,000. Thats new fuel injectors/cups, good used cam and rockers with labor For guys that run into the same issue as i did, look into used, its not the best option but when you have absolutely no funds, there are a ton of good D13 engines from rolled over volvos. AGAIN THANKS
