[irish320i]

thanx for that will be starting the loom tommorow should nt be to much hassle with the engine on the floor

[irish320i]

got the wiring sorted i think wont no till its in the car and i turn the key and that s gonna be a while still no closer to a solution for the gearbox there s so many options located a e30 325 sports box lsd and shaft for £350 in the north so thinking this is probaly the way to go. think ill order a standard 325 exhaust system this week as dont want it to noisey then ill just have to modify the manifolds to matcu up to it what do ye think

[Brianmoooore]

ill just have to modify the manifolds to matcu up to it what do ye think

That's what I did. Thought it would be a pig of a job, but it took less than an afternoon from start to finish, using bits of old E36 and E30 downpipes.

[Jhonno]

i think it was m12x1.5 Not the standard m12x1.75.
Measure it !!

just dug this up as im bout to get on with some bits..

what does the 1.5 or 1.75 bit stand for? depth? i know the m12 is diameter

[DanThe]

Thread pitch, ie 1.5mm between the tips of the threads

[buster]

pitch of thread mate.

OOops too late

[Jhonno]

worked it out after i popped out obvious when you think about it..

cant find anywhere that does M12x1.5 tho

The baffle attached to the engine (ie sits in there still when you remove the sump) does that need to come out to clear?

[Jhonno]

right did a quick search - i assume the one in the sump is removed (wasnt there in the 1st place in mine) and the other one left..

its quite exciting seeing the insides of an S50 (except if you Bigpimping i guess) - looks like it might have oil squirters for the bottoms of the pistons like the s14 evo lumps maybe.. (tho could be totally wrong with that )

[jmc330i]

The baffle attached to the S50 engine does need to come out. The M50 sump wont fit with it in place.

[Jhonno]

oh right.. so there is no baffle in the engine at all once its done?

Not got round to bolting the e34 sump on as the drill bit i bought doesnt fit in my drill so still gotta drill n tap the oil return..

got my nice shiney new e34 pickup in place now tho

[jmc330i]

I nearly had a shock when I saw the word 'drill' - I forgot what you were needing to do. I fed my oil return into the dipstick tube, so I didnt need to drill the sump.

I havent got the baffle on my S50, and Im sure Ian hasnt either. It definitely wouldnt fit on mine.

I also had to read it again after seeing 'drill' . Mine is also tee'd (or more accurately - Y'd) into the dipstick tube.

No baffle in mine, and I don't recall having to remove one either (engine or sump).

Ian.

[Jhonno]

howd you do that then? Sure i read to drill and tap it back into the sump.. to late now anyways, drilled the pilot hole

[ian332isport]

howd you do that then? Sure i read to drill and tap it back into the sump.. to late now anyways, drilled the pilot hole

I just drilled a hole in the base of the dipstick tube (above sump level) and had a small pipe spigot welded on the side of it. BMW did it like this on some models.

Ian.

[Jhonno]

this is the oil return from the plenum to the sump.. sure thats what was done with it.. well its what im doin with mine now

how did you 'tee' or 'y' it into the dipstick?

Ian.

fair enough.. will it be ok how im doin it? bit worried now Sure Buster did it like this. Or ive read wrong

[jmc330i]

My M50 sump didnt have one, but my engine did. I just checked the ETK and the 3.0ltr had the baffle but the 3.2 Evo didnt.

For the oil return, I did the same as Ian. I actually used the metal (I think Brass) pipe that uncsrewd from the S50 sump and brazed it on to the dipstick tube so its in a 'Y' shape.

[buster]

I drilled and tapped mine and re used the s50 fitting in the m50 sump.
The baffle is inside the m50 sump and needs removing before it'll fit.Also the braket on number 5 main bearing cap needs removing,and then re torquing.

Heres a pic of the pipe in the m50 sump after i drilled and tapped it :



from underside :



the baffle which needs removing :



This info is in my s50 thread.
Let me know if you need a tap and i'll send you one.

cheers
andy

[Jhonno]

ah yeah was gonna ask bout that also.. need new bolts for that then wont i? (the bracket that is)

ive done mine next across from yours away from the level sensor.. Might be a little long but i'll shorten it.

i'll have another look for a tap tomorrow (gotta return the drill bit anyways) but if not that'd be dead handy!! Wanna get a sump back on asap really

[buster]

you dont need new bolts.You mean for the main cap ? if so you don't need a new bolt,just use the old one
or have i missed something ?

[Jhonno]

the bracket that used to hold the old pick up pipe needs removing yeah? i thought it was bolted underneath the crank big end bolts.. might have been my lack of looking properly tho as i was worried bout getting dripping oil in my eye

[buster]

yeah its on 1 bolt.Remove it,remove braket then put bolt back in and torque to correct setting.I think its 20 lbs then 90 deg but ask Ian,he knows the correct setting.

[Jhonno]

ah - i was right. thought they were stretch bolts tho hence the whole new bolt thing

can see me bein on this thread alot over the next month or so (hopefully!! )

[buster]

Bingo !
Got me confused there to what you were on about.
Any questions ,you know where we are !

[Jhonno]

Yep..

Just put this back up so Ian can tell me the correct tightening sequence for that bolt..

[ian332isport]

Yep..

Just put this back up so Ian can tell me the correct tightening sequence for that bolt..

20Nm followed by 50 degrees

Ian.

[Jhonno]

Ta muchly.. gonna go buy me an angle tightening dooda whilst im out then

[bigpimpin]

Oh crap, Ian has just pointed me here, looks like I need to do the Y thing in the dipstick then cause my motors running and I aint pullin that sump off again to drill a hole!

I removed both mounting brackets for the pickup held on by the main bearing bolts. Think they were on number 3 and 5 from the flywheel end.

No baffle on my engine or M50 sump, definately not when I see buster's pic.
I initially thought my crank might have been hitting this and causing the racket I heard but alas twas more serious

[Jhonno]

this bit fouls on the sump (you can see the scratching)

do you reckon you could cut it in order to keep most of the baffle (reckon its there for a reason) or would that cause issues with oil supply?



Also.. Oil spray bar you reckon?




If i took the engine no. to a stealer, do you reckon they'd be able to tell me more about the car it came from? had issue trying to buy a throttle cable before as there are loads of different ones.. where would the engine no. be? only no. ive seen so far is 22C93

[bigpimpin]

I asked the same question, Ian332i replied.

"It's on the left side of the block just above the sump gasket. Have a look behind the left engine mounting arm, down under the starter motor. There should be a machined flat section of the block with the number stamped on it."

[Jhonno]

anyone have any thoughts on the baffle cutting?

[DanThe]

Just looks like one of those crank scrapers to me.
If it was mine I wouldnt cut it.

I would just remove it

found it..

removed the baffle/scraper altogether as thats what everyone else has done and didnt want to arse it up

another quick Q.. whats this bit? (on the left with the smaller belt.. i assumed it was a water pump but that looks like its up by the head..)

http://www.realoem.com/bmw/showparts.do ... g=11&fg=18

[bigpimpin]

Thats the Air Pump and the other is the Air con pump. I ditched all that.

[Jhonno]

it isnt needed then? Excellent, less drag on the engine
