I am brand new here, so I’m not good at the using the forum yet. I have been reading from this site for about 7 years and you guys have helped me plenty. I’m on my second LB7, that’s all I’ve driven since 05. I currently have 276000 on mine and it’s about time for the 2nd set of injectors. My question is, should I think about rebuild at that mileage before spending 3 grand on injectors?

Thanks, it does have a little blowby. enough to get the tube and front corner of the oil pan wet between oil changes. But it never drips on the ground. How much does yours have at 400?

You could check the compression and go from there but I wouldn’t just jump into rebuilding it just cause it has 276k on it.

That tube is the crankcase breather so if the pan is wet it's doing its job. Other than head gaskets/studs my engine still running on what the factory built.....except for a few sets of injectors of course!

408k on my LB7 and it runs just fine. No reason to think it'll need a rebuild short of 1,000,000 miles.
