E30, shoehorn, m30. i knew it wasnt dead.

i'm surprised that black tape held for 5 mins mate. i'd get another hose from GSF (and a thermostat while you're at it, you'll soon save the 8 quid in fuel costs!) then have a proper go at bleeding it.

it's probably ok, just not filled with water properly. you need to fill the rad with the top hose detatched from it, and fill the top hose too. then i'd undo the water res mounts and hold that up with the bleed screw open and the engine running heaters on etc. bleeding is not hard.

even if the HG is gone it's not difficult or particularly expensive, and once it's done it isn't going to go again!

yeah that tape was pure desperation!

could that be letting air in as i tried to bleed it?

thermostat sounds like a plan, same as the pipe. i dont intend to try bleeding it until i have those parts.

i think the gasket might be ok? will i save fuel with a thermostat?

how much do you think it will cost for a HG change at a garage? it was £300 on my 205 Mi16 but that wasa 16v so will this be cheaper being a 12v?

oh and here is the soft question - water res mounts.........?

is that undo the entire thermostat? as i have been bleeding through the header tank with that rasied to the sky. is that essensially the same thing?

[Toby_Unna]

yeah just lift the header tank high up mate.

i'm not sure what happens when you remove the entire thermostat, i think you're supposed to just remove the core to make an engine run cool. i think with it removed completely the coolant might not flow right - someone else might know more about it. but just put one in anyway!

and as for the HG, do it yourself - it's a simple enough engine to work on mate, nice and big. like Duplo.

[ric325i]

Duplo!

oh man the amount i have learnt with this project is unreal!

well we romoved the thermostat as we coudnt get it to bleed past the thermo?

so we just chucked it.

dont most big turbo boys ditch it too to make it run cooler water all the time?

[gareth]

ouch!
mine repeatedly ate the top rad hose til it was pulled tight (from repeated trimming!!!). that cost me a fair few £ for a new one from bmw.

make sure you don't overtighten the hose clips as the edges are tight. old hoses are very prone to failing if tampered with and especially if overtightened.

edit:
don't remove a thermostat on any engine as it'll never get to temperature properly and as a result will wear rapidly. also, the cooling rates across the head will all be screwed up risking uneven cooling and warping etc.

a neat way to bleed the other side of the thermostat is to remove one of the blanking plugs or temp senders from the housing.

yeah i think i am a victim of this

i had to shorten the pipe as i split it when i lifted the engine in so i made sure the hose was tight on........maybe too tight?



i dont think i have the tallent to change a gasket? i will check the haynes manual to see if it seems possible. hope i dont have to though.

[bigun]

it sounds like your not bleeding it properly there should be a bleed screw on the thermostat housing fill it up with water with the engine running let it get a bit warm and loosen the bleed screw you should hear/see the air come out i put my heater blower on warm if your having real problems you could squeeze a electrical screwdriver in between the hoses and fittings other than that is your water pump good and thermostat just my advice other people will have their own way

[ric325i]

yeah porn king it seems everyone has thee way of doing it.

i have never done it before this but now i have a few ideas i may try everything? but i need that pipe before i even try.

the tape may be sucking in air which could be causing the air block.

a new thermostat is on the cards.




11 months of trying for it all to go balls up so quick. there must be a way to get it going again.

[DRIFTBOY]

Aaaarrrrggh Ric!

The M30 is a tough old thing, I'm sure it'll be fine once the hose and thermostat is done.

Take care with the long bolts joining the two parts of the thermostat housing, they are thin and they often snap!

As has been mentioned, must be worth putting a water pump on while you are at it, they aren't very expensive if you shop around.

[gareth]

mine did overheat at first...... until i found that i had the fans wired backwards!!!!!!

it was fine in town but overheated at speed!!!

[ric325i]

gareth thats actualyl funny! i feared that so much. it takes balls to admit one of those mistakes

may do the water pump?

what a pain it is.

i have to get it going again it was so much fun!

i have been doing motor way miles in the 335i since i have done it and not that many fun road miles! i have only once had it flowing through a few bends.. it felt great to ease the throttle out of the corner!

and a few power slides in the wet.


so i will see where the nearest euro parts of GSF is and get on it tomorrow.

[Toby_Unna]

gareth thats actualyl funny! i feared that so much. it takes balls to admit one of those mistakes

.

i'll admit to that too, i don't care, i'm a bloody idiot

i turned up to mot mine with its new turbo in a massive cloud of steam, it was fine in traffic and at 70mph but at 20-30 it was like a bloody furnace, just got hotter and hotter!

[ric325i]

guys will i be getting bad flow if i have bends in the rad hoses?

like this...

top rad aint too bad


bottom rad is a bit of a tighter bend





can i cut these and slide them on?

i wanted to do it but i was scared the pipes are to small as they look like they flare near the end?

[ric325i]

now the question of how many times have you drove down the road and realised you have forgot to tighten your wheel nuts.

i count 3 times the 2nd was on the way to the mot place.

'whats that knocking noise?'

[DRIFTBOY]

I cut my bottom hose down because of this.

It does help stop it kinking but it's very tight to get on the radiator - loads of washing up liquid helps!

I can't say how much of a difference this makes as I've always done it that way.

[charlE30]

Gutted to hear your having problems mate your kinks in the hoses are no where near as bad as mine, I'm using a standard 325 rad and haven't cut the hoses as I will be fitting an E28 535 job at a later date. It didn't cause any issues with bleeding the system...

You've done so much already mate you could do the H/G yourself, I've got the 5 series Bently manual (much better then haynes) if you want I'll try and borrow a scanner and send you all the relevant pages for doing the head gasket... You might even enjoy doing it, it is fun stripping down engines and seeing all the guts

Charlie

P.S cheers for the info on the exhaust system dude I've just found out Jetex is about 8 miles away from me

[ric325i]

washing up liquid nice idea!


charlie no wories about the exhaust info, i just held things and passed Gall the tools as he welded. he made his own Y-piece and back box from my old 318i box

good man.

i am going to buy a centre box from jetex to dull the noise down as its too much at the moment. not that i can drive it.

i really hope the gasket has not gone. i will try and bleed it with a new pipe etc and see if that does the job?
then i may be able to drive it to a garage for a pressure test.

[snoops]

ok here is the video

its actually really pants but i have to post it anyway.

here are some pics












sweet!

the strut barce is point less but i paid £16 inc postage so it has to go on - get what you pay for hey.

love teh car!

thats quite loud but

where did you get your strut brace from? 16 quid?

[gareth]

gareth thats actualyl funny! i feared that so much. it takes balls to admit one of those mistakes

i'll admit to that too, i don't care, i'm a bloody idiot

i'm sure there are more of us out there!!! i blame the shitroen fans

Yep, me too!

[gareth]

haha!!! come on you lot, own up!!! we'll all big and stupid enough to do it!!!! who else!!!!
while we're here, who's connected their heater pipes back to front?

[DRIFTBOY]

while we're here, who's connected their heater pipes back to front?

D'OHAAAARRRGGGHHH!

[Toby_Unna]

yup

drove mine for ages like that, could i work out what the fcuk was wrong with it? no. not until Andy told me anyway

[McPower]

Good work.
Y look for turbo to 318is.
You can give some instructionses to me?

Gracias

[ric325i]

while we're here, who's connected their heater pipes back to front?

D'OHAAAARRRGGGHHH!

i wouldnt even know if i did....or have? now that is scarey!

[DRIFTBOY]

You get an annoying 'clicking' noise from behind the dash at anything above about 2000rpm with them the wrong way round, the heater valve going funny and that!

[Theo]

I had them on the wrong way round, and when I removed them forgot to mark them so I dont make the same mistake again. Where should the pipe T'd off the top rad hose go? Upper or lower pipe on the heater box?

[ric325i]

ah i dont know if thats happened, i have only done about 300 miles in the beast until the issue and that was all motorway bollocks with no heater/fan. fan would have been good though, 70mph with the window down just makes my ears flap in the wind.


getting the pipes tomorrow, see if i can bleed the beast and bring it back to life

[ric325i]

back on this thread i got told it didnt matter.

[Theo]

Well it will make a really annoying ticking noise with them the wrong way round, not sure if it has any real detrimental effect though?

[ric325i]

well i didnt notice so thats a good thing.

ok other stupid things we have done......


how many electric shocks??? this week? i had 2 on wednesday trying to disconnect my battery what, its in the boot its easier for the spanner to hit the shell

[johnl320]

Disconnect your neg first then when the spanner hits the shell hey presto no sparks.
Oh and reconnect your neg last.

I didn't bother renewing my coolant pump and it lasted about half an hour

[ric325i]

ha ha nice idea john! i just had to get shocked a few times to get the idea

its the best way to learn............i also sleep with my sister

[TheKoose]

Great read this thread has been, congratulations

[ric325i]

thanks thekoose at 1st it was just me writing and writing but now its a full on thread!

with lots of ups and downs.


i will let you guys know if i get it bled today
