What did you do to your E24 today?

sharkfan · Post by **sharkfan** » Tue Jun 30, 2015 4:45 pm

I think I've cured an awful lot of wind noise on my 635CSi.

Whilst taking the internal b-post trim off to sort out a badly seated door seal I pondered why I was getting so much wind noise from the very corner of the door at the base of the mirror triangle. On opening the door and looking up at the underside of the top edge of the wing at the base of the a-pillar I could see daylight edging through where the top of the wing meets the edge of the windscreen scuttle panel/wiper mounting panel. This would be quite a high pressure area when moving, made more so with the assistance of the profile of the A to C post gutter trims of the E24.

A few minutes work with some rubber strip, a pair of scissors and a touch of lube and I have filled said bits and it seems to have greatly reduced the higher pitched wind whistling through the corners of the door.

I suspect when new there was no gap or some kind of flexible stopper but after thirty years and new wings there was an easy to see gap there. More testing tomorrow when I get the M6 out and see how that sounds.

I think there is meant to be a small gap that water can drain through (and maybe air can make a noise too?), but the bottom of the slot should be sealed and painted. If someone removes your wings and doesn't put them back on properly, there could be a very big gap and that could be very noisy.

I'd appreciate a picture of the wing gap, if you get a chance: my burgundy six has had new wings and there is, indeed, daylight, but it's never reached the top of the "to do" list.

Changed my alternator and power steering belts and purchased a battery charger since I keep leaving my boot and doors open overnight after working on my car

It now starts on the button and there's no annoying/scary chirp and squeal from the engine bay

I'll have to look into what black magic is involved in getting the AC belt on another day. It looks impossible from where I was lying, but if I did get it on then I think it might foul the lower radiator hose when tensioned. The radiator is a new pattern part and the AC belt was missing when I bought the car, so thinking they may all be linked.

Picture of the wing 'gap' now filled with rubber; both my cars have have had new wings.

It certainly seems a lot quieter - I did consider trying to block/fill it from the the underside of the wing but this method worked out a lot tidier. If it starts to cause issues I can always take it back out - it's an interference fit.

From memory the gaps were 2.5mm to 1mm-ish

Ah! Thank you. I was thinking about the wrong area entirely. Your wings don't seem to stand proud on the inner edge like most of the replacement ones do - looks great!

I took a bit of time to ensure they didn't sit proud after seeing so many cars that did.

Replaced the 3.91 LSD with a 3.46. The car had the auto replaced with a 5 speed and the ratio seemed a bit steep. perfect for my style now. Also replaced alternator. Just stopped charging.

New low pressure P/S return noses, new P/S filter, flush with Redline Synthetics ATF Dex IV.
Scrubbed the carpet a bit.

Anyone have a good source for floor mats that don't have the dreaded balck foam on the back which comes apart? I need a beige set.

usually the regulator/brushes that clap out. If so it is a ten quid fix.

" Today was a good day "

Well , after 28 months my car is sitting on it's wheels again .
After getting the brakes bled and 100% operational I forged ahead and stage by stage brought it down on to the wheels .
I had to initially place the front and rear tyres on to wooden blocks to allow me to correctly tighten the front control arms and rear trailing arm bushes under load but she's down now.
After all this time with it sitting 500mm off the ground it was a shock to look down on it rather than over it , it looks so low

Will get it out of the garage as soon as this monsoon rain stops over here , get some photos and update my project thread .
Yep , went the day well.

Hey Sharkfan,
What's a "windscreen scuttle"?

wattsmonkey · Post by **wattsmonkey** » Sat Jul 18, 2015 10:20 pm

As per Gaz, no E24 action, but swapped out cam on E28 525i with help from Steve and both of my kids!

I'm not sharkfan, but I I'm pretty sure he means the area ahead of the windshield, and below the hood vents, where the windshield wiper mechanism, etc. resides.

the panel between the bonnet (hood) and the windscreen (windshield) is often known as the scuttle panel. The reason for this is that back in the day, that panel would look for all the world like a coal scuttle.

To this day any (esp. open top) car that isn't stiff enough if often said to suffer from 'scuttle shake'.

Today was a big and rough day completing three days of work.

My 87 M6 now has ...
1.) A new starter
2.) A new power steering pump
3.) A new alternator
4.) A new overflow tank
5.) New heater hoses - all three on the drivers side with new plastic t-fitting
6.) New stainless t-fittings for all the "burp" circuit hoses
7.) New breather and oil return hoses on the intake plenum
8.) All new hoses for the A/C and flushed oil in the compressor
9.) New, custom heat shield that works with the euro headers

Man .... am I beat. I'm very happy to finally have all that work done, though.

Jose

Where did you get the stainless t fittings mine has a plastic double t?

Did you say you were beat or broke?

Da_Hose · Post by **Da_Hose** » Mon Jul 20, 2015 10:46 pm

I found stainless T-fittings and just coupled them with a small section of hose. I am running waterless coolant, so the system basically has no pressure. I am not worried at all about the extra connections. I have some of the T's left over too. I can put up a pic. if you want to see how it turned out.

I suppose that if I'm honest it's a good amount of both beat AND broke.

finally upgraded. not sure why I waited so long...

GRNSHRK · Post by **GRNSHRK** » Wed Aug 05, 2015 4:07 pm

Finally completed the replacement brake MC from Carl (thanks Carl

) and bled everything out last night

I bought this pressure bleeder from ECS Tuning, nice tool

http://www.ecstuning.com/Search/SiteSea ... ES2774831/

I didn't use it "quite" the way they describe, which to fill the reservior with brake fluid and then pressurize and bleed

What I did was to fill the MC reservior, leave the bleeder dry and pressurize the system and then bleed. Sure, I had to remove the cap and refilll a few times, but at least I won't have to try and clean out the bleeder itself

Bleeding was SO easy

I did the clutch slave first, took maybe a minute

Anyhoo, done deal, hopefully good to go for another 35 years

PS: nice color, Carl

dwcains · Post by **dwcains** » Wed Aug 05, 2015 5:20 pm

I've had a Motive Products bleeder for well over a decade and it's one of my most useful tools. But, like you, I haven't been using it in the conventional way. Problem is that the vinyl tubing of the bleeder is quite soluble in brake fluid, and several years ago, while bleeding the brakes on my 350Z, the hose ruptured and sprayed brake fluid all over the engine bay, underhood, and left front fender. Within minutes I was able to make up a big bucket of hot, soapy water and clean everything before any paint damage occurred. Contacted Motive, and they didn't seem interested in hearing about what happened, but a google search revealed this is a well-known issue.

So, for now, I'm using the bleeder just as an air pressure reservoir (just used it again on the Z last weekend), but have found that EDPM rubber tubing is insoluble in brake fluid and will change the tubing to that. Another option is to buy a 10-foot roll of vinyl tubing at Lowe's for ~$5 and change the tubing after each use.

GRNSHRK · Post by **GRNSHRK** » Wed Aug 05, 2015 6:23 pm

Glad I went the route that I did

I used to pressurize the system with a total Rube Goldberg, MC reservior cap from a VW, with a hole drilled in it that fit a football needle

Then I pressurized with a small compressor, running back and forth between the caliper I was bleeding and the compressor, to keep the pressure up

One time "something" blew out and brake fluid went everywhere

Think I'll just keep it dry

Also painted the front of the vacuum booster, here's the before and after

sharkfan · Post by **sharkfan** » Wed Aug 05, 2015 8:14 pm

Discovered the intensive washer pump and main washer pump had seized - with my tools and spares packed up for an imminent house move I resorted to a very quick replumb and rewire to use the headlamp pump to run the windscreen washer jets.
