Thanks!

Can you make a video blocking off the air compressor like you stated?

I have a 2016 Peterbilt 389 Pride and Class with Detroit 60 Series. Special deal from Fitzgerald. High pressure in coolant system. Mechanic saying the engine got extremely hot and it’s probably a cracked head and possibly warped the engine block. The CEL came on a few times and the coolant temp went up to 210 to 215 and then the light went out and the temp dropped off to 140 and then back up to 180. Did this a few times. I thought it was the thermostat getting stuck closed and then open. There’s a class II oil leak on the drivers side of the engine above the air compressor. Mechanics saying $30,000 to overhaul engine. Any helpful advice would be greatly appreciated! Failed bubble test. Blown head gasket or worse?

The cylinder sleaves get holes in them if you overheat the engine. This allows air from the cylinder to get blown into the coolant which is all around the sleeve.

Part 2?

Information was in fact very useful. I've been for the last 2 years or so, running with an extraordinarily frequent dryer purge (every 5-7 seconds) three dryers replaced in the last year. Nobody gets to the root cause. Either because of lack or will or lack of knowledge.

on volvo clutch fan was leaking air witch would trigger airGovernor to start compressor every 1-2 minutes ... or any air leaks from compressor to governor

Cool shit i’m wondering, do you ever use the Lang diesel compression adapters? I know it’s a bit of a pain to take out the injectors to do the test with those

You may have air leaks especially the quarter inch hose on the engine if you have a paccar

Your the second guy that walk right up to the problem then didn't complete the diagnosis . what a let down .
