Cute, but I'm not putting a vehicle this old on a dyno, especially a 4x4.

I am curious about the RPMs cruising at 70 mph, though.

 

OK, 70 mph is precisely 2500 RPMs at cruise on a level freeway.





Just a datapoint for a 4.6 with the Crower 53229 cam on 18" wheels with OEM size tires.

 

What were your RPM's at 70mph with stock cam?

I used to be 2750 at 70 but now with electric fan I am at 2500.

Of course using the non accurate speedometer for this, not the UG speed or the GPS speed. And I suppose bigger than stock tires have an effect too.

 

If I remember maybe it was 2500 RPMs for 66 mph.

 

You may be right. As is common in my life, my new ELM 327 arrived, so naturally I then located my old unit that I had misplaced!

I plugged it into my Disco and ran the Chinese dash app Viecar 3.5 Mini OBD II.

Check out the pic. There's at least one translation problem going on it.

If "Oil Consumption L/H" is really "Oil Pressure in Bar" then 1.9 would be 27.5 psi.

Anyway, that's why I thought that maybe these ELM327 units read oil pressure.

...but, maybe the translation error is that "Oil Consumption L/H" really means "Gasoline Consumption L/H" in which case this app is trying to show me fuel flow, not oil pressure.

Hey, I don't know. So, you are probably right.

 

Update: my daughter's put ~~ 7,000 miles on my rebuild with no problems. Starts instantly. Revs like an F1 beast. Idles perfectly. Drives fabulously.

Life is good.

 

Good to hear, I am considering pulling my motor out and refreshing it up as you have. Thanks for the update

 

What I wish that I had done was use a dremel to hand grind the exhaust ports on the heads to match the exhaust headers at the inner edge of the gaskets.

What I like that I did do was:
ground the crank .02 and used .02 oversized rod and main bearings,
used new finished cam bearings and new crower cam+lifters,
machined the heads flat,
lapped the valves and verified that they no longer leaked,
replaced the valve stem seals,
used ARP studs,
used Cometic all-metal head gaskets (no more slipped sleeve tick!),
new oil pump gears and timing chain,
honed the liners,
blueprinted the piston ring gaps,
flow-tested the fuel injectors,
JB Welded over my new freeze plugs,
and installed new coils, plugs, and wires.





Honestly, I'm thinking that there is a market out there if I wanted to do more 4.6 motors like this for others to buy from me. Maybe add the inline thermostat mod if I was selling such a zero-miles rebuild in a running Disco 2.

 

Sounds like a big liability

 

Sigh...

Well, life is still good, but my daughter's Rover isn't. Cracked block or metal Cometic headgasket failure at 184,000 miles. Not an overheat problem. Just a poor quality block from the factory finally giving up the ghost (warpage or crack). Coolant is pouring out of her exhaust.

I won't be doing a Disco 2 build for the Barrett-Jackson auction now that I've seen this weak block firsthand.

It still drives if you add coolant, so I'll retire it out to my ranch for the occasional overland trip there. No more road miles. I'll be cancelling its insurance. It will literally be a future barn find for someone else.

I'm disappointed. There is just so much to like about the Disco 2, especially with its Crower performance cam. When running, it has useful 4wd capability and a luxury interior.

I had uparmored the interior panels with ballistic panels and uparmored the glass with security film. This beast was bulletproof stealth.

It will be in a barn in North Central Texas for the next 10 to 20 years so if anyone ever wants a great chassis with lots of goodies and a reasonably clean interior just send a private message here and then post to this thread so that I get an email to come view PMs, otherwise it will just be sitting in a barn. I'm not going to put any more $ or effort into it.

Randy is now parked. Possibly forever.
