Hey guys,
Thanks for your suggestions back at the start of the year with my no-fuel, non-sparking 924. Following me checking every wire out, transplanting each bit individually onto a mate's 24 and it all checking out, paying an autoelectrician and having one of my dad's friends who is an electrician and a nut on 70's 80's cars I just can't spend anymore time on her. So she's in the back of my dad's shed, awaiting a fate.
So I got another off ebay, but this time I knew a bit more. £800 got me a near identical 85 car. Full service history, uncracked dash, immaculate interior, sound engine and transmission, and perfect bodywork except for a small impact on the passenger mirror which will be easily solved. She is up in Nottingham now and driving me to work each day. I love it! The plan is to stay 100% orginal except for my cd player, an alarm and maybe some 20mm rear wheel spacers and spiderweb alloys in time.
I've typically got some questions tho' after the necessary pictures!

1. The engine shakes a bit at idle, I was thinking worn engine mounts and I have a spare set, but they look ok (not a great test) and the engine doesn't sway much when you push it (about half an inch).

2. There is a slight binding sound at the left rear axle when you're driving. Definitely not the drums. I retensioned the front wheel bearings as they were so loose, but don't know what to look for at the rear.

3. A few times when I have started it cold, I have to hold the key in the start position for about 3 seconds before it starts to turn over (and then it fires immediately). I cleaned the grounds and no change. Not having any 'typical' ignition switch problems, though I guess this could be one.

Thanks guys,
Chris

PS maybe i should change mzyvcpc as it is pretty meaningless to everyone here?? how do i do that?[img][/img][img][/img]

Being in the UK you might want some help closer to home as well as this forum
http://www.porsche924-owners-club.co.uk/.

My car shakes when cold but it settles real quick. Check your idle speed.

Could be a rear axle bearing for the noise.

I have a large start relay between the ignition switch and the starter. The ignition turns on this relay and not the starter coil so prevents burning out of the ignition switch. Might be worth a try installing one of these?

Gram-It almost made me cry the amount of time i spent on the first one, the worst thing was that I installed an alarm and stereo before i got the engine running A1, as it was I was driving it around with it cutting out every 20 miles for a few seconds. Then one day it just wouldn't start.

Ozzie-Idles at 950rpm, I've set the mixture and timing as per haynes. It does it all the time (hot or cold) when idling and you can feel it when you are sat at lights. Soon as you are at 1200rpm though its smooth.

I was thinking it may be the rear axle bearing. Its MOT comes up in 2 months and I know the guy who does it, I'm sure he'll point me in the right direction - it could still be the drum i suppose, but i think not...

Concerning the starter delay - that's a sign of a starter solenoid problem and it probably just needs cleaning. If it were clicking right away as you turn the key, but with no starter spin, that would mean it's time for a new solenoid. No click, followed some time later by the starter kicking in suddenly and turning the engine means the solenoid's gunked-up and a cleaning will fix it. -But if it's a major operation to get at (as I understand it is on a UK 924na) and/or the solenoid's old, then you might consider replacing it.

Thanks smoothie. I thought I could remember reading something on the forum a while ago about the solenoid doing that. I don't actually know much about solenoids...so time for some reading!

And mzyvcpc...it is boring...sorry Peter

well my email given to by nottingham uni is mzyvcpc@nottingham.ac.uk
They are standardised emails. The M stands for medical faculty. The Z and Y are something to do with the subdivision of the faculty. The V stands for my year (the one before was U, the one after W...) and CPC stand for my intials, Christopher Peter Cope. Aren't you glad you read that!?!

Nice looking car!
If you solve that problem with the delay starter, please post the solution. I've got the same problem so it looks like a new solenoid is in my future.

Chris..if my motor were to move 1/2" I'd be thinking of replacing one or both mounts. Does holding it over hard at idle smooth it out.? Maybe it's hard to tell?

After coming back this evening i tried that gram and i instantly thought "that's bloody hot". Did it again with a rag and doesn't really smooth it out. I'm going to do a few things to tune her up as I have nearly new everything on the other 924 and i have some O-rings as the current ones on the injectors look as old as the car. Then if it still does it despite a tune I'll look for a thread on changing the mounts. You are right, the engine shouldn't really move as much as it does.
Won't be doing that for a few weeks as I've got exams next week and then i'm on a triathlon training camp in Italy - big whoop. BUT i will past a 'solution' for the solenoid as soon as I've read about it and had a play.
Chris
