Default New Engine been sitting for over 10 yrs

need your opinions. I'm almost done wiring up the computer system. My motor has been sitting in my garage which is climate controlled for like 10 yrs. The engine always had oil in it and I rotated the engine without no problems every year. Should I remove the oil pan and check everything or pressure the oil system and send it? Also valve spring has been under pressure the whole time.

I would pull the heads and check for rust in the upper cylinders. Just because it was climate controlled, doesn’t mean it didn’t get moisture in there. Pulling the oil pan to check for rusty rods, crank, etc is also a good idea.

Sound good. Better safe than sorry.

A cheapo alternative..

If it's been turned regularly, and has been basically indoors, I'd send it. I sure as hell wouldn't tear it down for "inspection".

To those who have engines sitting around waiting to be installed do the engine a favor and back off the rocker arns until you're ready to use it.

I had a cup engine in a truck sit for 11 years…twice…22 years total. I pulled it out twice in 22 years to start it. Had to dump fluids each time obviously. Climate controlled basement. Zero issues each time. Finally sold it…tired of watching it sit. Show only tuck that my dad bought new. I owned it since ‘91. Here’s a link…https://autohunter.com/Listing/Detai...500-Show-Truck
