When I got my ExMoD 90 all the fluid levels were low and badly needed changing. So you might locate a shop close to what ever port your truck is coming in, and pre arrange changing out all the fluids and air filter and belt. I changed out my hoses as well. Plan on doing the same for the next truck.

A couple of technical questions for y'all.

Where do your temperature gauges sit when you're running? Mine is sitting at around 60% and I don't know if that's normal operating temp or not. Need to put a new sender and some VDO love in this thing when I get home.

Who's a good source for early Defender parts? I need a new clutch MC and an ignition switch and new keys. I figured I'd hit up Tillery.

60% or even a bit higher is what mine would show on oil. Coolant temp usually lower than that.

Trevor White at www.rovahfarm.com has a good supply of spares in stock for these.

Can one of you guys school me on the 2.5 NA dipstick? There are three marks. I think the top mark says DANGER HIGH or something like that. Where do you guys fill it to? The manual was a bit unclear on this and didn't have any photos.

High mark
Low mark
Minimum. mark

Should say H, L Min on the dipstick. Keep it right in the middle of H and L.

Guys, I have another question. As my trip progressed and I reached higher elevations, the clatter from my engine got much louder and the truck smoked more. Is this normal? It's quite loud now. It sounds like metal-banging-on-metal clatter.

I'm running Lucas fuel additive per the directions on the bottle.

Black smoke is normal as altitude increases due to lack of O2 with the non-turbo engine. Increased clatter is normal for winter diesel, I'm not sure that I've noticed increased clatter with altitude though.

Chris, I have a 2.5na as well and experience the same thing. I live in Virginia and recently took my 5 door 110 loaded with the wife, two boys, our dog and supplies for 4 days. We were packed. We climbed to 4500 ft several times over a 4 day span and it smoked and clapped. In fact I was concerned like you and was asking the same question.

x2 on that. You may also notice that your oil temps will run hotter as you're now overfueling at altitude. If your truck is going to live at high altitude then you might want to make an adjustment.

It might be worth posting a video or an audio file of the sound.

I can't think of a case where metal banging on metal clatter is normal for any engine.

Check the valve lash and the timing.

Make sure you are using decent diesel. Could you have gotten a bad batch?

I never recall any noise change with altitude. They obviously smoke more as there is no altitude compensation built into the fueling.

FWIW, mine is louder too but commensurate with higher RPMs.

So here's a little recording of the noises.

The noise starts at around 0:11 and is apparent from 0:25 - 0:30. It sounds louder in person. The sound is like what you'd get if you took some random metal scraps in a coffee can and shook it quickly (low amplitude) back and forth.

Ignore the rattling at 0:32; that's the radio rack vibrating against the roll cage





On a side note, I'm planning on driving the truck to Utah in a few weeks. The route takes me over Monarch Pass at 11,300'. Have any of you driven a 2.5 NA over a pass like this? I don't have any sort of EGT on this truck; I just have the coolant temp with the annoying "factory stabilized" gauge that never moves a bit. I'm not sure how I should do the drive. Maybe drive a mile and pull over and let it idle for a few minutes before driving another mile?

Chris, for some reason I can't get it to play on my end. Mine 2.5na does not sound as you just described so I don't want you to feel any undue comfort based on what I posted earlier re my noises.
Mine taps like these old diesels generally do. BTW, I had a Mercedes diesel mechanic nearby take look at her just for sanity and he said it sounds just fine. In any case, good luck with the trip to/from Utah and play safe.

The noise is something that I've heard while riding in military HMMWVs; it just seems more pronounced in my truck. It's not a grinding metal-on-metal sounds...more like popcorn popping, if popcorn was made of steel.

I had mine over Monarch and many others around here. Expect it to run hotter than normal. It may come close, but should not extend into the "red" portion of the temp gauges. Oil is going to show hotter than coolant.

I flogged my 2.5na like a rented mule and it didn't complain much. You'll be using your flashers on Monarch. I-70 is actually worse due to the pace of the other traffic.

Pay attention to your brakes on the downhill as well. As you know the front discs are non-vented and having no throttle plate, the diesel doesn't really offer much resistance to the gears going downhill.

When descending, the engine will very quickly go from hot to cold, and once cold it might start kicking out white smoke on the downhill. You might be tempted then to pull it out of gear and coast to avoid creating these stinking clouds. Try to avoid that temptation. I've experienced some brake fade with mine.

Btw I listened to the audio and I couldn't really tell that it sounded abnormal. I say beat on it and if that causes it to die, then it wasn't meant to live. If it survives, your confidence in it will increase.

Mine did leave me dead on the road once, due to a seized alternator that I replaced in Monument Valley. Other than that it was reliable.

If the truck is going to stay in CO long term then I would suggest turning the "smoke screw" counterclockwise two full revolutions (that's counter-intuitive, I know), and also consider advancing your timing a bit.

Thanks, Mike. That helps a lot. My oil temp gauge is flatlined and I need to trace the wiring to find out why.

I'm glad to hear that a 2.5 NA has made it over Monarch. My plan is to cross in the middle of the night when the roads are empty and just take it easy on both sides of the hill.

The good news is that I already have a new crate motor for it. I just need this motor to get me through the summer.

I know nothing of 2.5NAD's and that is an interesting noise. Sounds tinny, like fan shroud or similar. I am sure it is nothing that simple.

When you come out to Utah you coming to SLC? If so I would appreciate it if I could get a look at your truck. I was going to get one but decided to go another route.
