Does Anyone have a Dead 3.9 they want to get rebuilt?

[Disco_owner]

Hi guys,

would there be anyone out there with a dead rover 3.9 V8 that's lying around the shed / garage that would like to revive depending on the condition of the motor or wants to sell cheap that I can rebuild in my garage. If you'd like to have it back I'm happy to spend the hours building it on my spare time ,you can have it back for what I spent on parts.:)

My reasons for doing this is ;

A) To Learn
B) fill my spare time
C) & keep off the computer. apparently I'm spending way too much time on here.:(

I'd like to take my time to to do this just for fun. will take some photos and post them up as well. If anyone is interested.

I'm about to buy an engine building cradle /Jack , ( what ever you wanna call it ).so please let me know.

I ve got a 3.5 that I'd be happy for you to learn on - the only problem is that it's already in pieces. (Not by me)

Hi Diana

That should be fine. Is it a complete engine in pieces ? are you wanting this Engine back once it's rebuilt ? and what parts can be salvaged ? any idea ?

I have a 3.9 but I want to have the fun of rebuilding it myself :cool: - no I am not into S&M.

I will be going for top hat or pinned liners the price in rebuild is only marginal over normal liners.

The two questions I have not resolved at this time is whether to stroke the engine and whether to increase the compression ratio.

:eek: S&M ?

Also If you have an Engine and would are planning on rebuilding it yourself , they why reply? :p


Edit: Sorry Garry , that was inappropriate response , I'm not able to
answer the Q regarding the TopHat Liner Vs Normal Liner , someone
on here can answer that question , I'm also interested to know the
differences and advantage of a Tophat liner:cool:

I believe that it is a complete engine although what I have is quite a number of pieces in boxes, jars and tins along with the rest of the vehicle in pieces and boxes jars and tins. The only things that I may want to keep are the rocker covers for another stage 1 engine.

I don't need the engine back and you can have it just to get it out of the storage shed it's in.

Thanks for this Diana:cool: i'll make arrangements to pick it up , I can't imagine 2nd hand Rocker covers would be that exxy.:)

Oh well, another wild plan down the drain.:D

Ok - my points - no I do not have an engine but to do a rebuild properly without all the right gear and tools but can be a bit tedious and frustrating with certain specialist bits having to be contracted out. Rebuilding an engine can be a bit masochistic - tedious and frustrating but immensly satisfying in the end.

I appreciate you want an engine to practice on - that also implies making mistakes and possibly wrecking the engine in a worst case scenario or creating a masterpiece at the other end - and all in between.

Many dead 3.9s will be dead because of slipped liners - you need to learn all about this before you start. There are three remedies - refit standard liners (not good), use top hat liners to stop them moving in the future (can be expensive) or using a pin to hold the liner in place - most engineering places are not keen on this but some will do it - less expensive. Even if the engine does not have slipped liner you need to consider what you will do with the liners.

Most 3.9s have the lower compression ratio - do you want to stay with this or go higher with improved performance. What about pistons etc.

My original post in a round about way simply raised a couple of issues that you will have to decide on before you start the rebuild or about the time the heads are off - you obviously did not know about these.

Good luck with it.

Garry , I'm by no means an Engine Builder , which is why I asked the General Population here if there was anyone willing to to part with their motor for me to practice on , If you Don;t have an engine or donot wish to part with it , Why Reply to this Thread , I don't understand . May be I should change the Title ??? and Diana has willingly volunteered to part with her 3.5 ( Thanks ) . But I also did say in my post " Depending on the Condition of the Motor" meaning if it's got Slipped liners issues , I'm not willing to spend the dollars on it to get it up to standard.

I only want to to practice rebuilding an engine not to race it":D:D


Re: Specialised tools , I'm sure I'd be able to get hold of tools.:cool:

I thought the pinning could be done through the sump with the engine in place and that was one thing that made it cheaper. Is this not the case?


¿Qué?

There's this County in SA that needs some engine work.

Someone who was getting it done recently put up a post about it. I checked with a couple of engine builders and none of them recommended it and said they would refuse to do it if asked because they could not guarantee the engine.

Something I intend to investigate further.

Yep, think I'm thinking of the same post.;)

Stroking the engine will give it better low down torque, increasing the compression ratio will add a few more horse power if you combine it with other mods, but will usually require that you use higher octane petrol, Regards Frank.

We might have a couple of rocker covers on an old 2door rangie 3.5ltr motor;)
it's dads motor not shore if he will give you the rocker cover's i'll ask him:)

CHEERS TIM.

Simon , if you're serious about this county or considering to go down the path of the purchase ,I'll be willing to rebuild that engine properly:cool: , I can do all the work out of my garage. if you do then you've gotta to decide wheather you'd want to go down the path of TopHat liners for peace of mind or just Normal liners , not sure the difference in Price .once I pull the motor apart I would be able to tell what parts are salvageable.

great ,That would be Orsome.:)

[big guy]

Great idea buddy.

I did same many years ago on a VW flat four.
Learned heaps by making some mistakes and lots of questions.
Its not brain surgery and lots of fun.

Good on ya, I think there are possibly a few people that spend too much time on here.

Well done.

[Disco_owner]

Hi big_guy

The good old VW straight 4 hey , how much better did it end up going once you rebuilt it? Did you end up keeping the car ?

yes I agree, never thought of engine building as Brain Surgery either , it seems around here it is :angel: and no it doesn't need to be masochistic as referred to earlier may be a bit tedious ,but as the saying goes If you never never go , you'll never never know.:angel::D

Although I now have the space, I think the only use I'd have for a third LR is to sleep in as soon as it arrived home.:D

It would have been a good buy though....:( the price was suitable, I gotta get a Bigger place that has a big shed with a Flat driveway..:(

Mate if you just want to build a motor for the experance I will be puting a 4 cylinder diesel back togeather very soon (waiting for the bits to come back from the mechine shop )

Your more than welcome to sit in so to speak

Hi Tony ;

That's basically the Crux of it :) This should keep me pre-occupied , I wanted to start on a Rover V8 just to "learn"....it doesn't really matter , Petrol or Diesel, I don't mind coming over your place and giving you a hand either , how far are you and Panda? Is it a Fair drive from pennant hills??

Thought it might be, were just out of camden at a guess about an hour out of Pennent Hills,

in spite of what people would have you belive puting a engine back togeather is fairly stright forward, the hard bit is in the measureing everything up crank, cylinders ect ect

i'll let you know when I get the bits back, the build will probley be on a saturday and back into the skid-steer on the sunday (if all goes well)
haveing a few problems finding 20tho over size crank bearings at the mo
