About to buy a 6.0

[Polkville]

Howdy, been a member here for awhile now, rarely post, just read ALOT. Anyway, I have my sights set on an 05 f-250 ccsb with 101k. One owner. Truck is super clean except a squeaking belt. Had head gaskets replace with stock bolts under warranty at 40k and eight new injectors somewhere between 40 and 100k. I will have a CTS in the mail ASAP. Should I be concerned with the squeaky belt? Trk has k&n cai and a 4" turbo back silverline exhaust, 4 inch skyjacker and 325/??/18 Mickey mtz's. Also anybody willing to do an oasis report for me? Any comments/help greatly appreciated. Thanks in advance.

Also looks to have stock egr system in place. No evidence of pucking and starts good cold and runs super smooth. Sorry for the long posts, just excited.

The Squeaking belt is probably caused by the tensioner pulley, they always squeak, mine is doing now The tensioner can be replaced pretty easily, and get a new belt for it when you change the tensioner. No big deal. Also, replace the Filter on the K&N intake with a better one. My truck also came with a K&N which I replaced with a AFE ProGuard 7 filter. Or, you can get a whole new intake if you want. Do you have any way of checking the EOT vs ECT and FICM voltage now before you buy it? That would be a very good thing to do.

No way of checking before I buy.

Why did you replace the k&n filter? Are they not good? That's what mine came with. If I should change it what one should I put and maybe why should I put that one thanks

Well buy one. You'll need one either way and it can tell you if you have a problem before you sign on the dotted line. You can get a Scangauge for like $150. It'll tell you what you need to know and at the very least you'll have piece of mind. Just some friendly advice.

This is a good idea. You can get the scan gauge, or Edge insight CS or CTS (which you were planning on buying anyway) to check all the temps before you buy it. If you don't end up buying this truck, any of these can be used on almost every vehicle made after 1996, so it won't be waste of money.

I replaced the K&N filter because they are known to be turbo killers. If I can find a thread about it later, I'll add it to this post. Basically, the filter relies entirely on the oil for filtration, which is fine for a naturally aspirated engine. However, the turbo chargers on our diesels will suck the oil right out of it and all that is left is the 2 layer cotton gauze filter which doesn't stop much dust and dirt. Turbos really need clean air. I replaced it with an AFE 7 layer filter that has approximately the same surface area. AFE has a great reputation for making good diesel air filters, but there are other options as well. It was about $5 more than a replacement K&N filter and much cheaper than a whole new intake system and way cheaper than a new turbo.

Check the degas cap for discharge.
Run a pressure test on the coolant system.
I wouldn't buy it without checking the ECT-EOTΔ

Thanks that all makes sense I will get a little more use out of it and probably change over to the same one your running then. Now that one you suggested will fit right on the one I have though right...

Ok. I got it without checking the deltas. I know. I know. Anyway, I replaced the belt and tensioner today and the squeaking stopped at idle, but still squeaks when lightly throttled up. Ac on/ac off no difference. Sound seems to be coming from the alternator area. There was also a roar and the new tensioner seems to have fixed that. Any ideas on the squeaky belt? A boost leak crossed my mind, but it's more of a squeak than a whistle and it don't sound like air. So it's gotta be the belt.
