[DaveD]

thought you said you would get it mobile this weekend Lee

[E30BeemerLad]

read the link above Dave and all will become clear

[E30BeemerLad]

Right, got the mo-fo lump back in and most of the plumbing and wiring taken care of, the end is in sight, just hope the fokker is going to run OK after the diy rebuild and not knowing if the engine was knocking it's brains out to start with.

OK, questions questions for the M50 devotees.

1- There are 2 fuel pipes, one at either end of the fuel rail. Where does the pipe at the front of the car go to? Where does the one at the rear of the rail go to? Can you also give me an indication as to which pipe coming underneath the car is which? There are 3 in total. 1 runs on it's own near the sill, the other 2 run next to each other near the chassis rail. (my car did have cat & carbon canister)

2- There appears to be what is a fuel pressure regulator at the back of the fuel rail, there is no pipe on it. Where do I connect a pipe to on the inlet system?

3- At the front of the fuel rail there is a double outlet which I assume is some sort of breather outlet, where do I connect the 2 hoses to?


There will be more questions in due course, but one step at a time.

Being honest, i think the pod may be doubtful but i'm still going to try. Got monday booked off work to try and get some more progress made. Still got to fit the complete rear end, prop and then the fun is going to start with the exhaust system. Grrrrr

[OBs]

Fuel in goes direct to the rail (Rad end). The pipe from the pressure regulator is the return.

The thinner pipe under the return goes to the bottom of the inlet, it's the manifold pressure sensing pipe

[E30BeemerLad]

where abouts on the bottom of the inlet do you mean? Inlet manifold, throttle body, bellow?


Also, what's the deal with the heater pipes. I know the one from the back of the head is the flow into the car, but which pipe on the bulkhead does this one go to? the white or the black connector?

[DanThe]

The small pipe off the fuel reg is a vacuum connection to the inlet manifold, you need to look on the underside towards the rear

The plastic connector into the front of the cam cover, large pipe connects to the inlet elbow via the dipstick tube, small pipe connects to the rubber pipe inbetween the ICV and the inlet manifold

Hose from back of head goes to the lower one on the bulkhead

Any dodgy rubber vacuum hoses should be replaced, they will only cause you grief later on

[E30BeemerLad]

Thanks Dan

I think some hooligan has filled the hole on the underside of the inlet manifold where you are saying that small hose from the fuel regulator connects. More messing about, grrrr.

I reckon the dipstick I have is wrong as the tube is sitting under the inlet manifold and is impossible to get the thing to bend to a location where I could actually pit the dipstick in. It also just seems too loose in the hole for it in the sump. Do you have a spare at all fella or a pic of what I should have?

Have replaced a number of vacum hoses and the inlet manifold has all new gaskets as they came in the headgasket set. Got a full set of valve stem seals too, hope i never need to do them but as I have a compressor it is possible I could do the valve stems without having the head off again. New fuel hoses too.

Think I'm going to have to do some bodgery for the lambda sensor wiring as my plug from the car does not connect to the plug on the E34 loom.

[DanThe]

I would just buy a new dipstick tube, they are not expensive, approx a tenner

Think I'm going to have to do some bodgery for the lambda sensor wiring as my plug from the car does not connect to the plug on the E34 loom.

You mean the lambda wont plug into the loom?

[E30BeemerLad]

well the lambda i got with the engine has been spliced into that birds nest of a loom I had.

I was an animal when i took out the M40 lump and couldn't get the lambda undone from the M40 exhaust so cut the 4 wires coming out of the Lambda probe. The connector from the car side of the loom (with 2 grey & 2 white wires sticking out) seems different from the one on the M50 loom. They just don't want to connect.

Will get a new dipstick tube sorted

[E30BeemerLad]

Also, the M42 rad I have got is obviously a bit wider than the M40 one. So it doesn't sit on the little plastic shelf on the nearside of the front panel. Do i just get this plastic bracket from an M42 car?

And, what throttle cable do I need, E34 M50?

[ric325i]

or just rip it off and wled a bit on?



m42 stand should do for ya i guess.


you have been busy!!!! did you ever think you would be rebuilding an engine

[E30BeemerLad]

I ain't got a welder mate, just checked on realOEM and the bit i need is pennies so will get that ordered tomorrow along with a new disptick tube & O ring.

Yeah I never envisaged having to take the damn engine apart, spent more on that little adventure than what i paid for the damn thing, but hopefully it will behave well and redeem itself

If I get the wiring & plumbing sorted today then the fokker is gonna get fired up sans manifold

[DanThe]

You can splice the lambda onto a proper connector, but I wouldnt go cutting the plug off the engine loom, I probably have a knackered lambda you can have for the plug, if you can wait a bit as I wont be around much this week to look

[E30BeemerLad]

Cheers Dan, ignore my nonsense about the lambda plug I am such an utter f*ckwit, i have just managed to plug the 2 together. I must have been trying to plug the lambda plug into the air meter plug on the loom when it was all sat on the floor in the garage.

Anyway, more messing about. Can't get the heater hoses to plug onto the bulkhead pipes as I just can't get my hands into place with the inlet manifold on, so just taking that off at the mo (again!). Went to fit the clutch slave cylinder and snapped the poxy bit of metal pipe that comes out of it and nearly had brake fluid in my eyes, grrr. So another slave cylinder and flexi pipe is going to get ordered. So I can't fit the gearbox mount as i can barely get to the slave cylinder bolts when the gearbox is hanging down let alone in place.

Think i'll get as much done under the bonnet and then turn my attention to the rear end, or lack of it. Driveway is like a mud bath under the car too.

This thing is testing my patience

[E30BeemerLad]

After getting hacked off with needing some more bits for the M50 today I pulled the front ARB off, after a load of chew.

Got to buy some new front drop links as the old ones are a bit crusty, but it's a good deal thicker than the standard fodder, although doesn't look that much bigger in the pic. Looks like i need to mount the droplinks on the inside of the bar on the racing dynamics one


This is the bit on the underside of the inlet manifold where i guess the vacum hose from the FPR connects, the bit where some bodger has filled it with silicone What does the connector look like that goes on here, or is it part of the manifold and i'm going to have to do some kind of bodge?



Finally I decided to do a mock up on the front end. Imagine this coming up in your rear view mirror, or more likely sitting on the hard shoudler, with some yellow front lights

[DanThe]

Nice manifold mod

The connector clips in, its possible its still in the manifold under that lump of bodge. Looking here I would say number 11 is the piece

Definately number 11

[E30BeemerLad]

Cheers lads, this turd is just fighting me every single mo-fo step of the way.

Trying to fit the rear subframe and arms. The old metal centres of the old subframe bushes remained attached to the car when i dropped the subframe last year. Needed to separate the centres from the car. driver side came out after a big of wiggling and tapping with a hammer. The passenger side has snapped, leaving part of the bush centre stuck up inside of the car. I've been giving it some good news with a hammer and centre punch for over an hour and all i'm doing is making pretty indentations.

I swear, I'm not far from torching this piece of sh1t.

This car had better be worth it in the end

[E30BeemerLad]

here's the offending items, I'm not having a good day



This is what I am trying to chisel out, looks like it would come easily but it certainly don't want to break up. I've snapped 2 HSS drill bits also, grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

[Jhonno]

Bigger hammer?

[E30BeemerLad]

got the slugger out in the end, now fettling some new brake pipes and should then be ready to bolt it up into place, fingers crossed.

[E30BeemerLad]

Well after taking the day off work today I actually feel like I've made some progress.

The day started OK with an easy job of fitting my new front Racing Dynamics ARB. Then the fun started with the rear end, as shown in the pics on the previous page, over 3 hours of hammering & chisel action eventually saw the remains of the nearside rear subframe bush part company with the car.

So it was time to start getting this lot in


Space was really at a premium as usually when you have the back end of the car in the air, you put the axle stands under the rear subframe, but where do you jack the car and what do you stand it on when there's no rear end?
Had to make do with some spare wheels under the fuel tank/rear footwells. This meant that replacing some rear brake pipes was an experience I do not want to repeat with the car so low that the spare wheel well was almost touching my beer pod.

Made up some rear pipes and got those bolted in before offering up the rear subframe.

Used my pov spec trolley jack and after being a smart fker with the alignment it lifted into place spot on

Something of a milestone this boys, this shizzle ain't had a rear end on it for over 8 months


Springs & dampers will be getting replaced in due course.
and so it is, finally with a rear subframe and trailing arms back on.


Damn hard slog on your own.

Save for the arse ache of lifting the diff into place, I reckon the hard work is done now boys n girls

[daimlerman]

Well done,my man!! The diff. will also be a struggle,try to get one pair of bolts in finger tight,then jiggle the bugger up and down on your jack whilst having a grope with a finger to line up the other pair..

[Jamese30]

Looking good Beemerlad, keep up the excellent work.

Arghhh fond memories of lifting a diff into place whilst trying to align bolts.

[Jhonno]

Diff's are eeeeeeeeeeeasy!

[smithy318i]

Rusty fuel tank Lee!

[E30BeemerLad]

a quick sand & spray will fettle that one my good man.

Looks worse than it is, light surface rusy mainly

[daimlerman]

Fuel tanks fail where the filler pipe enters the tank,try wiggling the filler pipe up and down

[E30BeemerLad]

that's the first bit I checked and it is sound, it had a new tank 5 years ago according to the invoices which came with the car

[eko]

Nice progress Lee.
Its hard work on your own mate and I speak from experience but trust me it WILL be worth it in the end!

[E30BeemerLad]

Yes indeed, the mo-fo is now sitting on 4 wheels for the first time in about 10 months

Today I fitted the rear uprated anti-roll bar (got some rose joints in the post which I will be using as drop links). Then an hour or so of messing about getting the diff bolted up, tried the balancing diff on my chest trick and probably looked like i was trying to shag the spare wheel well to bypassers In the end the trolley jack did the trick. Managed to scrape most of the red paint off the diff when dragging it into position and using the jack on it, but i'm past caring what it looks like cosmetically underneath now, I know it is all fresh & tight as a drum and that's all that matters.

Back end looks like it is sat in the air on standard springs and the balloon like 60 profile tyres


Gonna give that fuel tank a good scrub, rub down and paint

The supervisor


Got to fit the drive shafts, got confused as to which set was which as i had the shafts that came off the car and then shafts that were on the 325 rear end i got complete. The set of 325 shafts look a little thicker and also have a thicker flange at the diff end of the drive shafts. One of the boots has had some previous bodgery done so I'm going to stick on a new boot before fitting them up.

This was a bit of a milestone though, I even pushed the car back and forward a few feet just for the sake of moving it, it's been so long

Time to turn my attention to the business end of things soon, the parts i needed for the inlet manifold and the new dipstick tub were picked up this morning from the stealers, so if the weather is decent tomorrow I may get this mo-fo fired up. Still not got my exhaust manifold

[town325i]

to fire it up with no zorst that will be fooking loud the neigbourghs will be pissed!!!!! o well they will get over it

[E30BeemerLad]

yeah she'll be loud without a manifold on

[DanThe]

to fire it up with no zorst that will be fooking loud the neigbourghs will be pissed!!!!! o well they will get over it

You should know! I bet the old ba5tard next door still has ringing in his ears from my old engine!

cool video Lee
