So we had a customer bring his truck in for his head gasket seeping (#3 head). We removed the head and found a shim on #5 and #6 hole. The customer called the guy that had overhauled the engine and he told him that the shims were something new that Cummins made to help seal better but to me it looks like someone installed liner shims on top of the liner instead of where they are meant to go. Has anyone ever seen shims on top of the liner under the head gasket? I will post pictures as soon as they arrive in my email.
N14 Head Gasket and shims? What's your experience?

I had one go back in 2004, sunken liners. Shop said they could shim the liners, but it was only a temporary fix and would not guarantee the work.
So I got rid of the truck. Definitely not a permanent solution. -
I think it was a company that made stainless cheater shims for Big Cam from CA. Not proper repair, but saved someone from overhaul.

I think this may have "repaired" long enough to sell...

Yes, it's a corner cutting, cost cutting cheap out patch instead of doing the job right. It's about 50/50 whether they hold up or not.

I've done that repair using shims with great success provided the liner wear falls within the cummins specs. There is a service parts topic on it.
BoxCarKidd, spsauerland and uncleal13 Thank this.
