That being said, it’s become a fairly accepted practice that is a practical solution to slipping liners. I’d ask around on the forum, maybe post a wanted ad in marketplace, and search the FB Groups. There’s someone who can do it for you but you may have to drive a ways.

As far as price goes, expect to pay a decent amount because whoever does it is taking on a big liability. They are literally drilling holes in your engine block so I can’t imagine it will be super cheap to pay someone.

Try to find someone who has done it several times before. You don’t want to be the guinea pig. It’s a pretty simple process, but in medical terms this would be a simple surgery but one wrong move with the scalpel it could go to hell in a hand basket.

Hopefully that helps? I’d expect to $1k or so. Top hat liners would cost A LOT more.

You might find a machine shop willing to take you engine block and put top hat liners in, but that part of the job alone is going to be around $1000. The pinning job takes about 8 hrs to do in the truck. Good luck!

Its certainly an odd situation, and the design and apparent manufacturing issues apparently create the perfect storm to allow it to happen.

I wouldn’t be too concerned about it unless you’re seeing high coolant temperatures, a loss of coolant, or something else is indicating an issue. If it’s otherwise healthy, then I’d just drive it.

Might be worth doing an oil pressure test to make sure the tick is not related to low oil pressure. That’s cheap and relatively easy/ well documented. Just need a $30-50 oil pressure test kit. Tons of good threads on the process.

Find where those are coming from and you might have found your issue.

Always suspect a leak from a hose or the water pump before assuming internal issues.
