Wranglin' the Beast: How to Run Overhead on a 60 Series Detroit (Without Losing Your Mind)
Ah, the 60 Series Detroit. A mechanical marvel, a symphony of diesel, and a guaranteed conversation starter for anyone who's ever wrestled with a stubborn engine. But sometimes, even the mightiest engines need a little TLC. Enter the glorious, slightly terrifying process of running overhead.
Now, before you crack open a beer and call in a mechanic buddy (hey, no judgement there!), this guide will walk you through the rodeo, minus the clowns (hopefully).

Gearing Up: Tools of the Trade
First things first, you'll need some essentials:
- A trusty set of tools: Wrenches, screwdrivers, feeler gauges (your fingers won't cut it here), and the ever-important injector height tool (because trust me, eyeballing it never ends well).
- A workshop manual: This is your bible, folks. Specifically, you'll want the section on valve and injector adjustments for your exact 60 Series model. Specs can vary, and you don't want to be winging it with a multi-thousand dollar engine.
- Patience: Lots of it. Running overhead ain't a race. Take your time, be methodical, and don't be afraid to consult a more experienced friend (or that aforementioned mechanic buddy) if things get hairy.
Safety first, always! Make sure you have proper eye protection, gloves, and a healthy dose of respect for the power you're dealing with.
Note: Skipping ahead? Don’t miss the middle sections.
Dismantling the Dragon: Accessing the Valvetrain
Now, onto the not-so-glamorous part: getting to the valvetrain. This usually involves removing the valve cover (which can feel like wrestling a particularly stubborn toddler), potentially the Jake brake bridge (if you're lucky enough to have one), and maybe even some other bits and bobs. Refer to your workshop manual for the exact steps – it'll save you a lot of frustration (and potentially some bent parts).
Pro-Tip: Label everything you remove with masking tape. Future You will thank you profusely.
The Dance of the Valves and Injectors: Setting It Straight
Here's where things get technical (but hopefully not too technical). You'll be adjusting valve lash and injector height according to the specs in your manual. It's a balancing act, a symphony of turning wrenches and checking clearances.
QuickTip: Slow down if the pace feels too fast.
Remember:
- Valve lash: This is the tiny gap between the rocker arm and the valve stem. Too much lash and your engine will sound like a bucket of nails. Too little and, well, let's just say things won't be pretty.
- Injector height: This affects how much fuel gets delivered to each cylinder. A misadjusted injector can lead to a whole host of problems, from power loss to excessive smoke.
Be meticulous! Double and triple-check your measurements. A tiny mistake here can have big consequences down the road (or rather, down the highway).
Putting it All Back Together: The Reassembly Tango
Once you've adjusted everything to perfection, it's time to reverse the disassembly mambo and put your 60 Series puzzle back together. Here's where those labelled bits of metal come in handy.
Tip: Read the whole thing before forming an opinion.

Tighten everything to the proper torque specifications – under-tightening is bad, but over-tightening can snap bolts like twigs. Refer to your manual for the magic numbers.
Victory Lap (and Common Hiccups)
You've done it! You've successfully run overhead on your 60 Series Detroit. Pat yourself on the back, fire up the engine, and listen to that sweet, smooth purr.
But wait, what if...
Tip: Don’t skim past key examples.
- The engine sounds rough? Double-check your valve adjustments and injector heights. A tiny mistake can make a big difference.
- There's a leak? Re-trace your steps and make sure everything is properly tightened.
- You're completely lost? Don't be a hero! Consult your workshop manual, a mechanic friend, or a reliable online resource (but be cautious of internet advice – not all mechanics are created equal).
Bonus Round: Overhead FAQs
How to tell if I need to run overhead?
There are a few signs: excessive valve noise, power loss, black smoke coming out the exhaust.
How often should I run overhead?
It depends on your engine usage and the recommendations in your manual. Generally, every 30,000 to 60,000 miles is a good rule of thumb.
