Porsche 924 Scheiße - hit and run

7,058 · December 22, 2025

I forgot one of the coolest parts of this journey.

On the way over to Cambridge on Sat, on the A14 around Thrapston, one of these gorgeous things loped down the slip road and joined behind me:

Not this exact one, but a silver X reg, same year as the 924!

We growled along at a steady 80 in our little early 80's convoy until he peeled off onto the A1. Much waving, and his passenger got a few shots of the 924 on his phone.

Very pleasing.

Emergency bolt had already worked loose, and the bottom bracket shows why... Time for some welding

Job jobbed

My latest patient arrived on the workbench this afternoon.

Which contains this lot.

Soldering actually all looks okay, but I'll reflow everything just to be sure. It's such a simple board it would be daft not to.

I suspect this is the cause of all the problems though.

It's really hard to tell in the photos as this camera really doesn't like close ups, but the relay contacts are really tarnished. I reckon just cleaning these up will get it working most likely. Will dig the points file out and give it a good clean and then see where we are. I'll check the caps while I'm in here as they could also be well past their best and causing issues.

Well, that's service! 🍻

The good s/h one packed up after 2 days, so might need similar tlc. The vendor is suggesting something on the car has caused it...

A pleasing pairing at Aldi this morning

So what else is new?

The car has been sounding throatier and louder since I thrashed it back from Cambridge 10 days ago. Full disclosure - I overtook everything offered between Cirencester and Stroud, and may have redlined the poor thing several times. It's a hoot to drive, to be fair: just enough power to be interesting, plus brakes and handling which make the effort worthwhile. However, I did wonder if I'd maybe been a bit cruel to the old bus and asked a little much of something only 10 years younger than me. On way back from Aldi the rumbling growl was accompanied by some clanking on the corners, and I had suspect #1 - the exhaust. Up on stands in the garage, the downpipe was loose at the manifold despite me having torqued it all up a month or two ago when I replaced the gasket. All tightened again and we have peace and nice smooth engine. Phew.

The other day the inlet tube did its trick of popping out of the rubber hose again. Bastard thing. On inspection the rubber hose is starting to crack and probably past its best, so I handed over another £50 odd to Design911 and a new one is coming. In the meantime I've re-seated the pipe very firmly in the rubber hose, and I think we've got the K Jet as leak free as it's ever been. It even hot starts properly! Plus idle and running is now really smooth, thanks to the lack of air leaks and the newly adjusted valve clearances.

Just got to sort the intermittent wipers now. I'm pretty sure there's something wrong with the relay and the chip inside is bolloxed. Which is a PITA but hey ho...

7,058 · January 10

The 924 has an oil spray bar to lube the OHC, plugged into the oil galleries by a small black plastic elbow. They're known to disintegrate over time and I noticed when I set the valve clearances the other week that mine had behaved to form. Here's what was left of it:

I think it still worked, just, but there's a guy on one of the Porsche forums who makes a brass replacement for cheaper than the new plastic one comes from Porsche or VW for that matter. £18 delivered, so it arrived this week and I fitted it this afternoon:

It's rather nice, and worth a close-up:

Took the opportunity to blast the pipe through with carb clean too, as the holes at the end had predictably clogged up with sticky crap so I got everything squirting freely again 😉before re-fitting.

Very satisfying.

Very nice! I like the brass fitting, it'll last forever. I will say the genuine (plastic) part from Porsche only cost me £4.30 last year! But it's still going to fail...

I've given up having intermittent wipers on mine, I just can't find a working early relay

Interesting - that must have been the last of the old stock. It was definitely about £20 odd quid when I checked a week ago.

D'you reckon only the genuine early relays will do the trick then?

Enjoying reading your enthusiasm for the 924! Got mine out today for a quick wash ready for tomorrow’s German car breakfast meet in Forest Row. Looking forward to a gentle blast tomorrow.

Its giving me pinto vibes pal. Seriously though what a lovely little future proof mod. 👍

I had a similar pleasing pairing this morning…

What are the chances?!

7,058 · January 11

We're being stalked by bearded, corduroy-trousered Geography-teaching Volvo owners, hoping for a sprinkle of our Porsche stardust and massive sex appeal.

It's the only answer.

I've ended up ordering this: https://ebay.us/m/yauLcK sent to a pal in Germany as thanks to our brilliant Brexit deal they don't ship to the UK, so he'll forward it to me. Fingers crossed it works.

Having had working intermittent for a few days, plus the feature where it wipes automatically when you pull for screenwash, I'd really like it again. It's a PITA without.

7,058 · January 23

I got updates.

The new wiper relay arrived from the Fatherland today, along with 3 cans of finest German beer from my mate. It now does all the good intermittent stuff, plus wipes the screen when you pull the stalk for screenwash. Let's hope this one lasts. I think there is a chip or something more complex in them which fails.

I pulled the bumper off last week to investigate getting the headlamp washers to work again. I know I bought another elbow for the pipework but fucked if i can find where I put it, so replaced the bumper (2 bolts!) and plugged in the lights & indicators. Except one of the indicators had a spade terminal that pushed back into the housing, allowed the wire to fall off and short the indicators. Bollox.

This blew fuses (obvs) but also fucked the indicator relay. Replacing both of those still gave me indicator weirdness - relay going mental, telltale on but no indicators etc. Hmmm. At this point you should know the Porsche's fusebox and relays look like this:

That's the passenger footwell BTW. Usually the battery tray rots through and it all gets drenched and doesn't work. Mine was dry, but had been standing for 25 years.

If you've ever dealt with continental fuses before then you're probably way ahead of me. I went through all the fuses, cleaning them and the fusebox contacts with sandpaper then meths and a cotton bud, and EVERYTHING WORKED PROPERLY!

Old cars, eh?

2,837 · January 23

I love that the fuse box on that is virtually identical to a late 60’s beetle. Only good thing about those fuses is it’s easier to wrap them in foil/wire/nail as a get you home bodge!

Order a new elbow then you’ll put it somewhere safe when it arrives and find the other one there….

Aside from it kicking you in the cods every five mins, what do you think to it? Are you bonding??

I was born in 1970, so to me a Porsche 924 is impossibly glam, and I still feel like Templeton Peck when I'm driving it. No matter that it's a VAG parts bin special, it's the badge on the front and that futuristic shape with pop-up headlamps that matter... 😉 No-one ever comes up to you in Morrisons car park to bend your ear about how their dad / grandad / uncle had one for hours, and the generation that seems most transfixed are the under 25's 😆, who just stare but don't come and talk to you because you're not a phone.

It's great to drive, with enough power to have fun and that steering feel you only get with no PAS. It's also refined enough to do speeds it really shouldn't on the motorway, and will happily keep pace with the outside lane pretty much no matter what you're with, in the UK at least. Tops out at 125, and I suspect that's about right. Ride and interior are pretty comfortable for what it is and I've fitted a good wireless and speakers, with that all-important electric aerial 😉. Front tyres are currently the Peter Sutcliffe of rubber, these circles of slipperiness: https://whattyre.com/products/hilo-xp1-genesys/181515/ so I've ordered a pair of new Continentals which I'm hoping will stop it understeering like crazy in the wet. Which is currently all the time.

Great little cars, and really undervalued IMO. Way better than a Capri or that kind of stuff, and still only £2-3K for a runner with no rot issues because galvanised body. Worth hanging onto, I'd say.

14,081 · January 24

Brilliant. Glad your happy with it after all the effort 👍

7,058 · February 14

All running pretty well at the mo. Car is filthy from lots of dirty wet motorway work, and I'm not washing it until it stops raining.

NVH work next. Under bonnet foam left the chat many years ago so I have new stuff from Design911. But first got to clean off the old mush. Bon Jovi moment:

And all done:

Next puzzle - should there be this small hole in my throttle butterfly?

I’d take the advice of the great Tom Jones on this - it’s not unusual.

Had similar age things with a similar hole, seem to remember it was to do with smoothing transition between the idle circuit and the throttle plate opening, but that might be nonsense!

I've got so much regret for selling my old toofah. Genuinely loved mine.

Brilliant, brilliant cars.

Still so many tatty ones around. Imagine what that would be worth if it were a Capri

5,023 · February 14

I've plenty of tatty cars sat around that I need to get rid of.

I'd like a nice one.. I need to clear decks a fair bit to get myself to that point.

Yeah, that's kind of what I mean. It takes a lot of work to turn a manky, down-at-heel 924 into something you can enjoy.

Mine was a good one..it was also stripped.. ex Practical Performance Car mag staff car.. had a nice posh bucket seat, some cut slicks and was a bit lower.. it was also a no rear wiper, no sunroof and manual window car.

Good gravy did I enjoy upsetting much more expensive and powerful cars with that thing.

February 15

The other end of the spectrum 🙄

Who was that? I loved writing for that magazine. They had a rat-infested unit in Corby. There was always something daft going on there.

924 = cool.
