Smoking 930, HELP !

[Kevins 930]

Hello everyone.

 

I am new here, having been reccomended to your forum by a chap who recently purchased a few parts from me.

 

This thread is about my 1989 930.

 

I have owned the car for 12 years and it has a genuine 33,000 miles.

 

I have not used the car for 4 years, but have recentlly strated her up to drive out of my garage.

 

Clouds of blue smoke, that do not clear after leaving her ticking over for 5+ minutes.

 

The petrol is also 4 years old.

 

Has anyone any idea's where I should look for a solution this problem??

 

Thanks

If it was ok the day you drove it in I'd say your fluids are your problem, obviously you will know that 4 year lay ups do these cars no particular favours, drain both the oil and fuel and start again, 4 year old petrol will have lost a fair degree of its combustability.....

 

It will need running for more than 5 mins to clear the smoke after this too.... Take it out for a good spin after you do the fluids, making sure the brakes haven't failed before you go too quick. Report back after...

Thanks for input.

 

yes it was fine when I put it away, always maintained twice a year despite maximum 2000 miles a year.

 

I have to check over the brakes and a few other bits and pieces then go on the road carefully.

 

I was worried about turbo oil seals???

How much smoke is there? I think that would be more obvious than the amount you spoke of but you never know.

 

Are there any oil leaks when its running but stationary?

No oil leaks, but I will check again.

 

as to amount of smoke, it always gave a puff when starting from cold but that only lasted a second or two.

 

The smoke now is very blue and dense but if I hold the revs at aroun 1500 almost dissapears until the revs drop, but it will not idle without throttle being opened.

 

thanks for input

I'd bet me hat its old flat fuel thats your problem.... get rid and keep it for the lawn mower... Clean new fuel, a new fuel filter and a good spin will sort this I bet. You wouldn't start drinking a half drunk bottle of beer again after 4 years....

 

Do likewise with the oil and filter...

I was worried about turbo oil seals???

 

Turbo oil seals only work when the turbo is spinning - if the turbo wheel & shaft assembly has stuck during storage then it could be bleeding oil into the inlet and exhaust. Even at idle the turbo wheels are doing a few thousand rpm.

 

It might be worth removing the compressor inlet pipe and giving the wheel a quick spin to check its free - you never now you might have had a mouse nest in there !

 

Does the smoke smell of burning oil or more like half burnt fuel ?

[Kevins 930]

Thanks everyone.

 

I am heartened and will report back in a few days time when I have changed fluids and filters, checked brakes and had a little run out. If all cleared I will then get stuck in with re-commissioning.

 

Oh how I missed this car for a few years !!!!

Mine smoked like a good un after 6 month lack of use, a good couple of days use and doesn't at all now, expect the odd puff on start up.

[jbl930]

Blue smoke is usually always oil, black or dark smoke is usually fuel. If your turbo is shot I have a mint stock 3LDZ you can buy, would be cheaper than rebuilding yours.

If you remove the intercooler and look for excess oil in there, that will tell you if your seals are gone in the turbo

Hi Kevin,

Welcome aboard, looks like you've had some useful advice above.

Cheers, Al

[carreracat]

welcome, '89 930 with 33k miles! sounds like a cracker! get some pics posted for us!!

[Kevins 930]

Yes I will post a few pictures. Maybe early next week as I have to do a few bits to the vehicle over the weekend before taking her to a photgenic location.

 

yes its ALL VERY original, I just havnt for a number of reasons used her for a while but kept her well stored.

 

Guards red with grey/silver/black leather interior.

 

Thanks once again for input from the forum.

An update................

 

I have not had any time for the past few weeks so no progress on my 930 untiul today.

 

I checked oils, brakes etc and decided to start her up and run up and down my drive a few times.

 

All go's well the smoke was clearing very nicely after a few runs, but the engine would not idle, I let it stop and have not been able to start it again since.

 

So now that I have more time I shall progress this over the next week.

 

Best wishes

I am not sure I have the hang of this, bu trying to upload a couple of pics

 

Kevin

 

And trying again

 

reading a few posts..............Is it that rare to find an untouched 930 ??

 

 

 

 

I will take some better pictures and get them up.

[Kevins 930]

So the progress...............

 

Changed fluids has indeed remedied the smoking well grey smoke problem. Moving forward I now have a noisy rear fuel pump which I will need to change I am sure, but can not start the engine when its warm, it just reuses to fire, so have to wait a few hours before is starts again and then it is always first or second pull.

 

Has anyone any idea's ???

 

Thanks

fuel or a sticking starter motor on its way out

Loss of pressure in the fuel system...... dodgy fuel accumulator or one way valve.

Given that my rear pump is squeeling like a banshee, loss of fuel pressure may well be a real problem, I guess a chage is the answer?? repair may not be an option, unless someone knows differentlly

 

 

Many thanks for input

Hi Kevin

Going back to your earlier point about rarity - an 930 is always noteworthy, especially a 5 speed '89, but an original one of such low mileage is just dandy - lucky you, hope the problem sorts itself.

 

On the plus side - there aren't that many cars that would start so easily after a 4 year lay-up - great cars!

[Kevins 930]

I have had the car a good few years.

 

I did have a complete service record, I still have the book, but every bill MOT, bill for any works etc etc, but My ex wife burned them !!!

 

Does anyone have any pointers on diagnosis for the components mentioned above??

 

Kevin

[johndglynn]

Welcome Kevin.

 

The ideal thing to do for your hot start would be to check the pressure in the fuel system and watch what happens after the car is knocked off when warm. Accumulator is always a potential culprit in hot start scenarios but there are other parts to check as well. Have a little search in the fuel and ignition tech sections.

 

Lovely car! I'm sure you'll sort the niggles out soon enough.

[Aldo]

That car is a beauty. I'm sure you will sort what ever it is soon.

[Kevins 930]

thanks for support everyone.

 

Yes I will sort it out, and I would rather do so as a DIY project, as I have some time to attend to it at the moment.

 

It seems quiteunusual to get such an untouched 930 it appears judging by some comments, and mine looks just like the day it came out of the showroom, the only thing that I know isnt original are the front shocks which were replaced by AFG at Chiswick for what they called "uprated" items, but that was when the vehicle was one year old. the bitumastic around the top mounts show that the change occured.

[Bearcat]

Kevin....you have a beaut of a 930 that deserves a specialist mechanics attention. I had pales of black smoke out of mine and it was an injector snag......me says with respect stop farting about and get an expert to give that beaut you own the once over. Any chance of a pic of the engine bay?
