engine rebuild

[4wheeldrive]

this might sound a little crazy

but at the minute i am currently at college working in motor vehicles
i have basic knoledge on how an engine works, but would like to further improve my understanding on how an engine works, i learn best by doing things my self and hands on
i have been offered a running 2.25 petrol out of a series 2a for £50
and my plan is to buy it and fully strip it, then put it all back together, doing this a couple of times will certainly improve my understanding of one, and when i eventually get a series myself i won't have any trouble repairing the engine ect.
not including the intial £50 to get the engine,
roughly how much should it cost to do a basic rebuild of the engine, just replacing the parts that are worn ect?
thanks to any good replies

 

[jamesmartin]

not that much but i would be very surprised if it didnt need rebore which you should do anyway and make sure they hone a least 1 thou to piston clearance size cost £120 4 x new piston and rings £40 bearings £20 ,probably around £400 to make as good as new engine ,otherwise just take it to bits and back together as practice ,its one of my favourites to do apart from 300 tdi, if you get duck egg blue from local paint factors it look good,ive done quite a few if you want any tips

 

[4wheeldrive]

yeah, its purely only for practice, as when i get my series thats when i'll be spending serious money on parts of the engine

i don't plan to put the engine in a car to run on the road, i'd just like a 'project' if you like to practice my rebuilding skills, and my dads had quite a few series landies and hes no beginner in engine rebuilds, so i could always fall on him for advise, but thanks for the heads up about tips knowing that i don't want to get it like new, how much do you reckon i can get away with spending, as any money saved is going towards my actual landy when i get one

speaking as someone with no knowledge (well very little) but will soon be doing this to my series 3 petrol engine. i would think that if all your going to do with it is to take apart and put back together then you would only need new gasgets (someone correct me if i am wrong) and i think a full kit will cost less than £20 plus any fluids needed. will be watching this thread closely due to the task ahead of me...

If he was going to do this for a college project why not do it right and make it a new rebuilt , why waste your time and effort to make a **** job out of it. Oh teacher i rebuilt it but it runs like ****. Or teacher i rebuilt it with new rod bearing, check crank, new cam bearings, rebored new piston and rings and rings are end gaped, new gaskets and the likes. Which would be better for his effort and how much more would he learn, buy doing a complete job instead of a half arse job?

If you re-build it properly then you will be able to sell it and recoup any money spent.


Series71 on here goes through engines like there's no tomorrow.

Strip and rebuild a couple of times then refurbish it! Build a cradle to run it in (with any old radiator) to test it, once you are confident you can strip and rebuild it so it works then you can think about rebore/ pistons/ bearings etc. No point in potentially trashing new bits until you can do the job confidently.

 

[Vagrent]

That is a fantastic idea

As some of the guys say, go for the full rebuild. as you can either use it in you series when you get it or sell it on and get ya money back and you may make a profit

If not the knowledge you will gain will be priceless

I really hope it goes well for ya, nice one.

if you read carefully he says he just wants the practise in his own back yard, not for teachers marks, i also said that i was a complete novice and if it was already working fine then just gasgets change would be the cheapest option for him, he wants to take it apart, put it back together a fair few times. i agree that if it was going back into a vehicle then lots of other things should be looked at and changed. i would rather spend £20 a time to get the experience before spending hundreds on doing a full rebuild straight off.

NO where does he say In his own back yard. That is your interpretation of your reading comprehension skills .

 

[jamesmartin]

if you really need or want to know how engine works ,why they were built as they was and are now ,valve overlap, timing advance,compression ratios ,long versus square etc you will need to read up,putting an old one together is spanner practice and could be done with no parts ,putting one together and replacing worn parts as originally asked isnt done for a tenner, to learn about engines you need to learn about measuring wear in bores ,and were to measure,learn how bores are bored and honed to piston clearance size why there honed and how ,why a cold piston isnt round ,how and why to gap rings ,how there fitted, before moving onto heads ,timing ,oil system ,cooling etc ,read up before and during while doing it to your engine , an engine is either done properly or not at all you cant make a worn one half worn by spending half the money

thanks for all your input guys

it may have seemed like it was a project for my actual college, i was just stating that i go to college studying motor vehicle mechanics, so i have basic knoledge
but what i want to do is purely something for me to do to practice my engine rebuilding skills, once i am confident, yeah i will spend much more more replacing parts to make the engine like new, at the minute when ive only done basic engine repairs there's no point me spending real money on reboring ect as its purely for practice, when i get more experienced at rebuilding then i might consider replacing worn parts, now it seems rather pointless when all i want to do is expand my knoledge of an engine.
i will be getting basic bits, like an engine stand, a manual, and piston ring compressor tool ect, and will go from there when i get the engine, i will be taking lots of pictures during the rebuild, i'll post em on here if anyone's interested

We likes piccys on ere

Great Idea To do this I got given an old Bedford YNV to practise on in my Apprenticeship and an old text book took it apart and rebuilt it for spanner skills 2 or three times marking each bolt screw seal etc noting where they came out and taking a note of condition in a notebook as I went then then had to replace parts identified as worn etc as we needed it fitted in a bus (had such a smile when it started!) I learnt loads and gained alot of confidence from the excercise and am considering the same on a 200 TDi to brush up and jog my memory

JamesMartin do you have any textbooks you would recommend on engines? (or anyone else for that matter?)

 

[oxides]

You'll be needing one of these then :-
pdf Land Rover Manuals | Landroverweb.com

Better than a Haynes manual and a nice mix of technical info and practical tips.

maybe it is only my interpretation and my opinion, like i said if anyone corrects me thats fine as i am a novice so to web attack me because i gave a different opinion to the one you want is a little out of order. i came here to try and advance my knowledge, meet like minded people and to offer my opinions right or wrong and not to have my grammer and pronunciation and spelling been brought into question.

 

[b20wnx]

wow james and i was lead to believe that the old engines are easy to work on lol, surely you would only need to know all that info if you were a mechanic or training to be one, what about the simple idiots rebuild, would we need to know about piston bore etc, i think it would be too much system overload for me... TBH is was just going to use the manuals i have and have looked up on the internet, take it apart, take pictures, post on here and ask for comments ie good, bad, replace etc. maybe its the lazy way out i dont know.

 

[jamesmartin]

the engine is piston and bore ,you can get this done by someone reasonably cheaply and go from there,all old 2.25s will have worn bores ,and as i said you cant make an engine a bit better only properly or worse,if you was near me i could have helped you ,ive done a few with people they do it,with the manual i just explain or help every now and then

 

[b20wnx]

can you move house up here then james, think there one for sale just round corner lol
i have to say it is well out of my comfort zone and someone just keeping an eye on me would be great, but i do work real slow so a weekend visit would not be offered lol.

 

[4wheeldrive]

if your so worried about ruining your current engine, if youve got the cash, why not do what i do and just buy a project engine thats cheap and practice on that, thats what i'm doing and you can take all the time in the world as youll still have a running landy
