Today we got started on this 2019 Ram 1500 5.7 HEMI.
The water pump failed, the engine overheated, and not long after it started misfiring and burning coolant.
Today I got the heads pulled off and dropped them off at NAPA to be crack checked, inspected and machined. After removing the heads, I also removed 3 of the four broken studs. One of which broke off flush. I also cleaned out the residual coolant and applied a generous amount of PB blaster and wrapped the block in plastic to help avoid rusting while we wait on the heads to be checked.
Interestingly enough, the inner two cylinders on each bank are the ones that were burning coolant. You can clearly see the difference too — those cylinders are “steam cleaned” compared to the others from coolant making its way into the combustion chambers.
The good news so far is there’s no sign of coolant mixing with the oil, which gives me some hope that the block and bottom end may have survived the overheating.
If the heads pass inspection, the next step will be drilling out the broken exhaust stud, getting the heads cleaned and machined, and then putting everything back together with a new gasket set, new head bolts, fresh coolant, and a fresh oil change.
But while I was tearing this engine apart, I couldn’t help but think about Psalm 139:23-24:
“Search me, O God, and know my heart: try me, and know my thoughts:
And see if there be any wicked way in me, and lead me in the way everlasting.”
Just like these cylinder heads, sometimes we can look perfectly fine on the outside while something deeper inside is cracked, damaged, or failing. We go through life feeling confident in ourselves, assuming everything is okay simply because we haven’t completely broken down yet.
That’s why we need the Lord to search us daily. To inspect what we can’t see. To rebuke us, refine us, and reveal the places where we fall short before the damage spreads further. A hidden crack in an engine eventually shows itself. The same goes for the us.
