Is the E21 3 Series worth saving??

Nice bit of blurb about the E21 from 2008 on Pistonheads.com, surprisingly at the top of an advert for a Henna Red 316 in the 'Shed Of The Week' section... lol!

Before Chris Bangle came along, BMW styling was simple. Whatever the size or intended market, you'd give it a well-balanced three-box profile, a thrusting shark nose complete with kidney grille, add in the trademark 'Hofmeister kink' on the C-pillar, then put the pen down, with the satisfaction of a job well done. No flame surfacing, no controversial rumps, just variations on an 'if it ain't broke then don't fix it' theme.
The first 3-series - the E21 - was the epitome of this styling approach. And it worked, too. During the course of the first 3-series' production run between 1975 and 1983, BMW factories in Germany, South Africa and Egypt churned out more than 1.3-million E21s, making it the best-selling BMW in history.
In doing so, the smallest BMW helped to define an entire class of car - the compact executive saloon. Now, junior and middle management types could afford a classy, sporty car that looked just like their boss's 5-series.
As you'd expect in a small BMW saloon, the neutral handling, rear-wheel drive, faithful steering and light weight make the E21 a car with track-shed potential, especially if you can find one of the later, fuel injected six-cylinder models.


A lot of people on there panning the four cylinder model E21s, saying only the sixes are worth preserving as classics. I'd have to disagree with this. There are so few E21s still left on the road in Britain, where rust and rot are magnified by 10, that surely they're all worth keeping. 1.3 million E21s may have been produced, but in the UK they were massively overpriced compared to their British Leyland or Japanese counterparts, all of which came with heaps more trim than the BMW and this meant they never really sold that well here in the first place, the E30 becoming a much more common sight in the 1980s. Never the less, Morris Marinas and MGBs, both using the same BL 1800cc lump, are cherished, restored and no one could suggest they be broken up to save one scrapped hot model like a B V8, and who is to say the genre-defining E21 is any less significant or rare?
A 323i for instance is faster than the 316 for sure, but it would get beaten to a pulp by a modern 320d and besides, in a 30+ year old car how fast can it really go? Components are going to be worn and if the car is truly well looked after is it worth pushing it to the limit? Ok, so there are going to be people buying E21s that are destined for the track, but a classic car will need serious modifications for this and when the chassis and brakes have been done is the ancient M20 323i lump going to feel so fast? The real way to make a go-fast E21 is to swap in a modern injected BMW engine. M42 (316/8i) and M43 (318is) engines from the E36 will drop straight in without any modifications to the engine bay and these 4-cylinders will already be keeping up with the six-cyl originals - they'll also be more reliable and a lot easier to find bits for like injectors, ahem. By this point though, you no longer have an original classic and that's the true essence of preserving a car this old.
Who cares if it won't melt tyres when it looks this good? E21s are all about keeping alive the shark-nose BMW tradition that began to fade away with the E30. The quad headlights from the 3.0CSL also became a mainstay on the E21 and brought with it the transition into the meaner looking BMW's of the '80s, most notably the E24 6-series and E28 saloon. Before this were the much softer, European looking models with two large bug-eyed headlights, like the gorgeous 2002 and original E12 5-series. The 315/6/8 E21 hark back to these historic models, where the sixes heralded the sporty future and boy-racer image that bound the marque from there on. This, arguably, makes the single headlight E21 models the prettier car and even more worthy of preserving with the '70s models, as true BMW classics.

Does an early '80s E21 316 with an M10 run on unleaded fuel?

The answers before I bought the car pointed to yes but it turns out that the four-cylinders might not after all. Ignition timing is fine, apparently, down to as little as 92-octane unleaded fuel, but valve wearing is still a problem and an additive is recommended. It's about £8 a per tank so could be expensive over time. I don't reckon the previous owner had been putting any in regularly or they would have given me half a bottle with the car, so I think I'll be taking my chances.

The other thing is regular 95-octane unleaded or 98-octane super. The engines are designed for 100-octane leaded petrol so regular unleaded might be a fair drop performance wise, but does it make a difference to the valve wear?

As we parted company the previous owner said to fill it with super to get the best out of the engine, but said it would run fine on regular and that was all that was available to me at the filling station so it had to do. The car charged home without a grumble from the engine and feels very lively indeed, though I'll be filling it with super next and see if it makes any difference.

UPDATE: It turns out my engine has had the hardened valve treatment so it can run any unleaded without excessive top-end wear, so I haven't needed any costly, annoying additives and that's a relief. The engine seems happier starting up and a bit livelier running on 97/98-octane petrol, which is what I've been using for the infrequent use the car gets. Obviously the power gain isn't vast on a 100bhp engine and super-unleaded is dear stuff, so now I'm starting to use the car a lot more I'll be switching back to 95 RON for the sake of economy.

Fuel Consumption:

I've worked out from averages that my late 316 M10 1.8L engine, running a Weber DMTL carb. and the 5-speed 'sport' gearbox is giving me ~26mpg, which isn't bad at all really. Using the lower octane 95 RON fuel may give better mileage, or may make it worse, either way I would imagine the difference will be negligible given the amount I drive the car.

A few inspirational shots of slammed E21s...




Getting the E21 home...

BP garage on Sutton high-street in Surrey where I near brimmed the tank for fifty quid and set off 240 miles home.
Cannock services, north of Birmingham. Didn't want to chance stopping too far south and have the car refuse to start up again, so I pressed on to within recoverable distance. It started instantly, but you don't know with old cars. It was running slightly hotter than norm going uphill and slightly lower than norm under easier cruising. Maybe the thermostat is starting to play up, or maybe it's just an old engine with no electric fan.

Finally made the move and bought an E21 3er!

I've been looking at E21s for sale for about 12 months now and good but tatty examples in my price range are getting thin on the ground so I am overjoyed to say that I have finally agreed a sale on a lovely Henna Red 1983Y 316 with tan interior.

The driver's seat is well ripped and the paint has faded, but apart from that its, er, mint. The body is very straight, no accident damage and absolutely no rust. E21s are famous for rotten sills, arches and boot-floors. This is perfect in those areas, it looks to have been undersealed from new, mainly garaged and the boot interior waxed to the same extent as outside.

Unfortunately it has a few modifications, but not enough to spoil the original car in any way. The original wheels are painted battleship-grey, which looks great and it has an immensely cool AC-Schnitzer steering-wheel, though the original is thrown in too along with a zillion other parts and a 2-ltr engine, yep, complete with block, flowed-head, the lot. I just haven't the guts to try and fit it I'm afraid. The macpherson-struts, top-mounts and control-arms are new, which is good as they are known for dying, but the shocks are now SPAX adjustable coilovers and the only thing you can't alter is ride height - she's stuck at a permanent 60mm drop. The previous owner swore it had passed MOTs with no problems to arch clearance, but I'm still praying every day. At least the suspension is tight and no clunks round bends or bumps so I guess that outweighs the stiff ride. Thats it for the mods - for near 30 years old thats good going.

It has MOT only until the end of August, but a fresh 6-months tax, so I don't think I've done too badly to pick this thing up for £900, a hundred over my budget, but in better condition than I imagined for the price. Now I've just got to get down to Surrey and drive it the 240 miles back...

BMWs at Tatton Hall Classic Car Show 2012

For the full story on Tatton Hall Classic Car show 2012 and over 120 pics go here: Tatton Hall Park Classic Car Show 2012 [on my other blog: http://retrorunabouts.blogspot.co.uk/]


The BMW UK Owners Club had a mighty big stand celebrating the Queen's silver Jubilee, with all manner of classic M cars and the brand new M6.
Alpina B5 Turbo E28 5-series was superbad and superclean in black.
 AC Schnitzer sorted E46 M3.
E30 M3, a genuine left-hand-drive article.
Tidy E30 325i with Alpina wheels parked up amongst the Ford RS owners club.














Some of the best BMWs were away from the OC stands, including this pristine green 2002 I found tucked away behind a load of Volkswagens.
The condition of even the finest chrome work is absolutely concourse, the paint and wheels original.
 It could be said that the 2002 has seen better days, but the owners proudly display a picture of them driving the car from new in the early '70s and it looks in a shabbier state then.
 Grilles and bumper chrome work all look exactly as if they've just rolled out of the Black Forest.

A little stand previously hidden by the busy food stalls revealed a couple of sweet 635 CSi...

 ...and this luminous yellow 3.0 CSL 'Batmobile' race car, which was one of my favourite cars of the show.
I was being optimistic by hoping to see a standard 3.0 CSL at the show and was not disappointed because thats what this is. The car started life as a regular CSL before being bought as a wreck by the current owners and rebuilt to exact 'Batmobile' spec.
The level of detail to the aero-body is so good that the car can't really be called a replica - it's more of an upgrade.
415 wide rear tyres - like a Lamborghini Countach or Bugatti Veyron.

E39 530d: Fuel Leak?! .... Quickly Sorted. [M57]

Okay, today lets talk about fuel pipes. This little spell of working on the car continues as we found a small oily patch on the drive after completing work on the prop-shaft donut, smelling a little like brake fluid and with no apparent origin. I spent the few weeks since then checking fluid levels and being cautious with the brakes, though everything with the car seemed fine. About a dozen small oily dots had appeared though in the meantime on the road where I park, so after systematically blaming every one of my mates old clunkers that could have parked there during that time, a large patch that turned up on Saturday suggested it had to be the E39.

On Sunday I drove her onto ramps for the second time this month, whipped off some of the plastic under-tray and had a good look around. Naturally I feared the worst and assumed that, while jacking up the gearbox to get at the prop, I'd ruptured a seal somewhere and was dropping engine-oil, meaning the engine would have to come out for the warped part/gasket to be found and replaced. With this in mind it was actually greatly relieving to discover the the leak was 'only' a corroded fuel pipe.

Turns out the fuel lines run externally, which is something I haven't seen before, and the metal sections are not covered by under-tray and are exposed to the elements, allowing them to corrode, although I don't know if them leaking is common. Seems a bit of a design flaw to do it this way, I mean it'd be a bit dangerous on a petrol car surely, but I guess BMW have done this to keep the noisy fuel pressure-pump [under the passenger seat] outside of the cabin on the diesel models. Mine had begun to corrode quite badly around the front pipe-bracket, obviously where it's been rubbing, but its been holding up and I guess whatever knock or shove I gave it while fixing the prop-shaft opened up a pinhole. I should be more careful when working under the car, but once you've spent two days squirming around in a tiny gap between soggy concrete and filthy metal, there's a tendency to become complacent...

It's not worth trying to repair the pipe, replacements are very cheap. I'm sure they can be found for even less, but I ordered mine from BMW Parts themselves [Part No. ] and it was only £18.00 inc. VAT anyway.


PROCESS:

Replacing the pipe is very easy. It's right behind the passenger sill, so you only need to jack the car up a little to access it, but the job is messy and diesel is nasty stuff so make sure you've got a plastic sheet down and plenty of tubs to catch it.
