My new 4300 project

[larboc]

My deere dealer took mine apart the first time but I put it back together after having the head redone so I know the pain the fuel tank is. Thank you for all your information. Was your blow by grey and smell like exhaust.

It was grey/blue ish and smelled like an acrid mixture of oil vapor and exhaust. If I held my finger over the crankcase vent for 10 seconds and then took it off the gasses coming out sounded like an airbrake coming off park.

Wow that seems like a fairly big difference. I just put a new top end in my RZR and the new pistons were down in the tenths, but perhaps they match them at the factory before sending them out. How are the ring gaps?

No idea on ring gaps, I'll find out if he checked them (this guy is pretty **** so I'm guessing he will). If not I'll measure before installing.

Word of warning, he had to order tooling to hone out the new upper rod bushings to size and is having a hard time finding the right size in stock anywhere. The correct size is on a long backorder. He's hoping fresh stones on the size below it will work, he ordered that one as well. This could take awhile. Evidently you don't just press in new bushings and everything falls together, you have to hone out the new ones after installation. I didn't know that.

I did drop $24 on 2-gallons of JD 10w-30 break in oil and a couple $12 JD oil filters. Also got a 5-gallon pail of +50 10w-30 JD engine oil for $93. It was 15% off at nortrax, but it still hurt a little.

That's the stuff. My old man always swore by it in the farm tractors. Oddly enough I don't see 10w-30 +50 advertised anywhere but the notrax dealer had it on the shelf in gallons and pails. 10w-30 fits the temperature range much better than 15w-40. 5w-30 would be better yet but I never see that available for a reasonable price.

I've been using Rotella T6 in my truck and next oil change I'll be putting it in the tractor too. It's a 5-40 and seems to hold up pretty well even after 5k miles. Auto zone sometimes has it for $40 per 2.5 gal jug and Shell offers a $5 rebate per gallon so it ends up being good value too.

How does one tell if the oil is holding up well after any number of miles?

Just by looks, or by some test ??

It would have to be sent in to someone like blackstone, otherwise it's just speculation.

Other oil my injectors would get really noisy after a while. They remain quiet now. That is what I am going by.

tks.. so far with Deere oil have had no noisy injectors.
