Looking to get a rough time estimate of an engine swap from 3.9 to 4.6 in a D1. Just the swap, not a rebuild. Thanks | ||

Could be done in a day if all goes well. Maybe faster if you have really small hands or a really strong 5" tall gnome to get to some bolts. /C | ||

Brian, I've heard about a day as well. I'm planning on doing a 3.9 to 4.6 swap in my Disco as well in the upcoming weeks. Personally, I'm budgeting two days downtime for the truck... just in case. Also, make sure that you have the cam spacer taken care of before hand. That'll save you some downtime as well. Thanks, Nathan Hindman http://www.pangaea-expeditions.com | ||

Nathan, what ECU are you going to use on the 4.6? Thanks, John | ||
| Brian Brown (Rtiqulatendisco) New Member Username: Rtiqulatendisco Post Number: 19 Registered: 01-2004 |
I've got the 14CUX with the 4.6 chip. What are the other options? | ||
| John Cinquegrana (Johnc) Senior Member Username: Johnc Post Number: 606 Registered: 07-2002 |
Brian, I heard you can use the ECU from a 4.2. I'm curious because I will be installing a 4.6 soon. | ||

Brian, I'm not really sure which ECU I'm going to use yet. I need to pick the brain of a buddy of mine who has been researching this for about 6 months now. I'll let you know what I'll find out. Thanks, Nathan Hindman http://www.pangaea-expeditions.com | ||

Have you _ever_ done an engine swap, Chris? FWIW - I've just done an engine swap, a 1-to-1 deal, same nearly everything. Took me two friends to help me to drop the engine in the bay, and about 15 hours afterwards to connect everything back up. All in all, a 5-day deal, with ALL tools (including power) at hand, no frantic searches for missing parts, etc., in a decent-sized garage. | ||

Brian, FWIW Eric from Atlantic British used an ECU from a 4.2 on his 4.6 powered Rangie (at least that's what he told me a few years ago at Roverfest). John | ||

"Have you _ever_ done an engine swap, Chris?" Actually Peter - yes and it is Curtis. Otherwise I would keep my mouth shut. If it took you five days to do the whole operation then you probably did not do simple things like shoot photos and tag and label every suspicious wire or hose before removing the old engine. You are right in one thing: It could take a week or longer if you have not dedicated the time, are missing tools, or do not do it right. But if you get started at first light, are organized, and have only one person helping it can be done by bedtime or sooner. I would be willing to be there are some on this board that can do it in under eight hours as well. Just not me, not yet. /Curtis | ||

Curtis, I don't know how could I look at your post and type a wrong name - but, I've done some other dumb things througout the day. I didn't need to shoot any photos or tag any wires - I remember everything in the engine bay, and can draw the wiring diagram from my memory. However, every little thing takes time. I think I'd stand by a 20-hour estimate (on putting the engine in); I've spent some extra time fiddling with the brackets (new motor had different accessories and different brackets, and I've spent up to about an hour to mix-and-match the hardware), and another three - completely rewiring the engine compartment (insulation becomes brittle after 36 years of heat). Also, I've made a mistake of not checking the bolt pattern on the flexplate, and the new one wouldn't bolt to the TC - so I had to drive to Sears for a 7/16 DeWalt drill bit and punch three new holes. That took another hour and half. Subtracting that, it's still about 15 hours - just putting a motor in an empty engine bay. Sure, some of the work can be shared between two people - whenever possible, I prefer to work alone. The problem with helpers is you never know what's been done and what may have been overlooked - one of guys who helped me to drop and tack the engine in couldn't remember which bolts did he put in and which he torqued; to go over all these bolts again alone cost me nearly half an hour later. But again, I knew what I was doing, had all the tools (but that drill bit), and I work not too slow. Not a beer throughout the process. | ||

that would be a really long day. we did one just a few weeks ago (my truck) and it was about 14-16 hours all said and done. but we did this over the course of a week or so. there will always be unexpected delays regardless of what you think. make sure you replace most of the seals while you have the motor out. intake, valve covers, main seals, etc. | ||

Garrett, What engine do you have now? Did you go 4.6? Glenn | ||
| gp (Garrett) Senior Member Username: Garrett Post Number: 2428 Registered: 10-2001 |
nope. just dropped in another 4.0. 4.6 was a bit cost prohibitive to me right now. | ||
| Joe B (Denverrover) Member Username: Denverrover Post Number: 154 Registered: 02-2003 |
Nathan - would you be willing to pseudo document your 4.0 to 4.6 conversion? Maybe main issues or problems that you encountered? Maybe price too if that would be ok. Joe in Denver..... | ||
| Nathan Hindman (Nathanh) Member Username: Nathanh Post Number: 152 Registered: 07-2002 |
Joe, We're going to go on a 4.6 installation spree, about 2 or 3 of them in a one month time. I'm sure that we can get a good average of pricing and pics, etc from the installs... We'll also do one in a 3.9, one in a former 4.0. Thanks, Nathan Hindman http://www.pangaea-expeditions.com | ||

I'm trying to figure out all the seals that need to be replaced... ideas other than intake, exhaust, rear main? | ||
| gp (Garrett) Senior Member Username: Garrett Post Number: 2429 Registered: 10-2001 |
valve covers. when you get the rear main make sure you get the entire 'kit'. will come with three seals. i would also suggest tossing in a new water pump. takes all of 15 min when the engine is out. | ||
| Joe B (Denverrover) Member Username: Denverrover Post Number: 160 Registered: 02-2003 |
That would be most helpful. Let us know. Joe |
