cat 3116 head bolt torque

According to the service records they have had a steady diet of rottella straight 30.When I pull the head off I will also clean the aftercooler and see how it looks.Maybe switching to a 15-40.Straight 30 is getting hard to find and expensive.I believe cat said the multi weights are fine now with todays additives.I have heard alot of negatives about these engines.I have only had them for a couple years.I have to say when they are running good the are very clean and efficient.I really kinda like them.Guess we will see if my opinion changes after I replace the cups and set the rack.

A modern 15w-40 might be just fine. Got any pictures of the boat?

Not having any luck uploading a pic but you can google carrver 440 for the model.

Thanks everyone so much for the info.I will check in with you this fall when I get the head off and keep you updated on the progress.

If I had a boat like that, I would hoist a flag that says “chillin’ the most” and I would rock that b$tch up and down the coast. Becky could quit her job at the C-store and join me. Until the diesel and the liquor ran out. Then, She woukd probably shack up with my neighbor because he has a regular job.

Sounds like Popeye made his way to alaska and shacked up with sea hag.
