Another catastrophic CP4 failure on a 2015 F350.

Same protocol as usual. Fuel system + DCR swap. We verified the engine is still in time and did not spin the crank gear.

These fuel systems are keeping the lights on the past few weeks! 2 more arrived today. One for a long block replacement and another for CP4 failure. Both of course getting DCR swaps!

2014 Ram 3500 in this week for some power upgrades. This one is getting a FASS Fuel System, 12mm CP3 injection pump, and 60% injectors from S&S Diesel Motorsport. She should make close to 600-700HP after these upgrades. The truck already has a Fleece turbo. The customer went with 60% and the 12mm pump, leaving him some room to grow into if he decides he wants to 2nd-gen swap the turbo or go with something bigger in the future.

This 2019 F250 got a full fuel system with a DCR conversion, S&B cold side charge tube, and a 23+ CCV filter. Now she’s getting washed up for pick up!

Next: Ford 6.7L fuel leak prevention kit made at S&S Diesel Motorsport

Here's information from the company: The modern diesel fuel system specialists at S&S Diesel Motorsport have created another solution to a fuel system problem tormenting Ford Super Duty pickup truck owners. Plastic is a great material for fuel filtration due to its corrosion resistance, yet the material’s strength can degrade after many heat cycles. This degradation has created a recipe for disaster for Ford trucks equipped with the 6.7L Power Stroke diesel. The plastic engine-mounted fuel filter can crack and spray fuel onto a hot inboard exhaust system and start the taboo four-letter word that automotive engineers renamed a “thermal event.” As if cracking fuel filters weren’t enough to worry about, the fitting that returns fuel from the injectors is also made of plastic, creating two potential leak points. The Ford 6.7L fuel leak prevention kit is the only all-in-one solution to both problems that meets and exceeds the OEM filtration specifications. Ford’s filtration is great. The problem lies with the plastic’s durability. The billet aluminum LPK solves that real problem. Yet the fuel system engineers at S&S are not going to create one problem by solving another. The decision was made to forgo the OEM fuel filter cup altogether and use a two-post mount that allows for a much larger filter that retains the factory filtration specs of 4-micron absolute at 99% efficiency and nearly double the dirt holding capacity (S&S 23 grams vs. OEM 12 grams). Fixing one leak point while leaving another does not make sense, so the aluminum fuel leak prevention fitting for the injector return comes standard with all kits. In summary, the S&S LPK prevents fuel leaks without sacrificing filtration. In a two-filter system, upgrading one filter without changing the other is not ideal. To make it easy, S&S created the Ford 6.7L Fuel Leak Prevention Kit Plus that bundles the LPK with a chassis-mounted replacement filter. Individual replacement filters and filter kits are readily available from the global S&S dealer network.

2008 6.7L Cummins came in blowing coolant out of the degas bottle on cold start. No emissions on this one. Found chinesium head studs and a majorly blown head gasket. Going back together with ARP studs and an OEM Cummins gasket set.

Certain years of the Wrangler JK were known for left over casting sand in the engine block. This one just had a heater core replaced recently at another shop and it’s clear they didn’t fully flush the block or anything else before and after the repair. This one had no driver side heat. The way the heater core plugs allows flow to the right half of the core and allows passenger heat while the sediment blocks the far side(driver side) and makes the driver side lukewarm at best.

I don’t always agree with Zeb but I can tell you that this exact situation he is referring to happens to all of us real shops that perform real diagnosis and charge accordingly. We end up with everyone else’s scraps and “we can’t figure it out”. Then we are the bad guys when we charge for our diagnosis and CORRECT repairs. There’s a reason our prices are where they are. That’s because you get real diagnosis, real repairs, and a business that stands 100% behind their repairs.
