Tackleberry Posted October 6, 2022 Report Share Posted October 6, 2022 (edited) Looking at a truck with the Commins N14. Head gaskets are leaking a bit. What's ballpark inframe cost in these? Thanks.

spindrift Posted October 6, 2022 Report Share Posted October 6, 2022 Why do you think it needs an inframe?

Chad Heiser Posted October 6, 2022 Report Share Posted October 6, 2022 I have an N14 and did a complete in frame on it 4 years ago. I also replaced the turbo and clutch and a couple other small items at the same time. The total bill was about $25k.

I'd have a reputable shop change the gaskets and perform a blowby test. How many miles on the engine?

My advice, have the engine evaluated by a reputable engine shop before spending $25-30K on a rebuild. Even if there is excessive blowby, you're going to want an inspection of your rods and mains in order to determine whether you only rebuild the top end or go the full Magilla and include the bottom end as well. My bad...reread and saw head gaskets NOT valve gaskets. I'd still have both bottom and top ends evaluated.

Darryl&Rita Posted October 6, 2022 Report Share Posted October 6, 2022 How much you got? In all seriousness, it depends on the shop rate in the area you get it done. Have you ever been inside this engine before? Headgaskets aren't indicative of an inframe. Get a manometer on the blowby, so you can make an informed decision. Roll in new main and conn rod bearings, replace the head gaskets, adjust the valvetrain and Jakes, and let her bark.

Wrknrvr Posted October 7, 2022 Report Share Posted October 7, 2022 I would think about judging the rest of the truck to compare how it was taken care of. If it looks respectable inside and out then that could indicate it was sorta taken care of. Now if other things are sorta tough, then it might be time to look elsewhere. Today I seen a local dump truck that had oil on the front right side lug nuts. It was very noticeable. I would think DOT mite pull him over for a inspection. Mismatched tires on the rear axle. Not very clean on the outside. Now no comment on my Jeep. I now it workings are respectable. Corvette motor with 80,000 miles on it. It may not look it. But it really is a rat rod in disguise.

Jaydrvr Posted October 7, 2022 Report Share Posted October 7, 2022 I spent $17,000.00 at the dealer for my N14 in-frame. That included the turbo and a couple other items I hadn't replaced yet. Jay Quote Link to comment Share on other sites More sharing options...

DUNE-T Posted November 15, 2022 Report Share Posted November 15, 2022 Just change the gaskets, n14 at 700k is just barely broken in, I really really doubt it needs an inframe Quote Link to comment Share on other sites More sharing options...
ddm502001 Posted November 24, 2022 Report Share Posted November 24, 2022 Biggest problem on the N14 is Heritage, is still a NT855 base block, they had issues for forever with Head Weeping for as long as I had worked on them. MINOR amounts of coolant are one concern, if leak oil can ignore except the mess. Blocks erode at water passages and as heads 'wiggle' on the block deck. As a quick check have a Mechanic inspect for broken head bolt in the head to head juncture areas, not unheard of to do this. IF has a broken Head bolt just do all three head gaskets and ALL new head bolts, do NOT let someone argue for reusing them. Way I used to do this is a solid Steel rod, about 5/8" diameter and about 18" long, lightly drop on end against head bolt heads in between heads, should bounce and ring, a 'Thok' or Weak hit with no ring will find bolt has broken.
