1994 940 282K

It would appear that I am in the market for a turbo cartridge for a 940. While I am not excited about the task of replacing the cartridge on this car the original has certainly given good service. I bought the car eleven years ago with 175K and it has been a good one.

I am working down a list of maintenance items the last couple of days. I replaced the waterpump and the oil cooler hoses today. After startup I noticed some blue smoke from the exhaust, but it seemed to clear up as it reached operating temperature.

The car was still on jack stands and the hood was up. I saw smoke coming from area of the clamp that secures the turbo to the manifold. I shut the car off and then noticed a small puddle of oil. It was dripping off of the bottom of that clamp. I can't imagine where it would be coming from other than the seals in the turbo. It seems to be very odd timing. The car hasn't not been losing beyond what has been its normal quart every 1000-1500 miles.

I will be doing some more exploring as well as removing the hose to see what kind of play is evident on the shaft.

Assuming I need a new cartridge (and deciding I want to replace it) where have any of you been buying turbo replacements?

Thanks,

Thanks for the replies. I am back to say my turbo/oil leakage problem has taken an odd turn.

I had the car on jack stands to gain access to the oil cooler hoses. I only raised the front on two jack stands at the jacking points. This raised the front 8-9" above normal level ride height (at the jacking points).

After replacing the hoses and putting in the new G-05 coolant I started the car and brought it up to temperature in anticipation of letting it cool and topping up the reservoir. It was at that point that I smelled and then saw smoke coming from around the clamp on the turbo. There was also a half dollar sized puddle of oil on the floor. I had seen a little smoke out the exhaust from cold start up but at 282K I wasn't concerned.

I guess I shifted to worst case scenario and thought the turbo was toast. Later that evening after a cold beer I took a more rational approach to what might be the reason for the oil dripping. I decided that changing the cooler hoses and refilling the cooling system with fresh coolant should not effect oil circulation/leakage. What else could it be?

I decided I had never run the car with just the front on jack stands before. Next morning I raised the rear of the car and placed two jack stands at the rear jacking points- leveling the car. After starting the car and bringing it up to temperature it still smoked at the clamp but it did not leak any additional oil. Letting it idle an additional 10 minutes eliminated the smoke at the clamp. I assume the residual oil had burned off.

I took the car out on the highway and gave it a good flogging. Checking the mirror under boost did not produce any sign of smoke. Returning to the garage and raising the hood only revealed a very hot turbo and exhaust but no smoke.

So now it would seen that there is not a problem with the turbo leaking oil. The question would be why would running the car with the front raised cause oil to leak around that clamp?

I haven't dealt with them in many years but had good service when I did--Turbo City -- in Arizona. -- Dave

Thank you for your response.

Google didn't come up with anything for that name in Arizona, but had an Orange CA. location that did. However, it would appear that they are closed.

FCP groton guarantees a their parts for life,,,& since 2005 I just buy new snd the old back & get credit.

FCP is my go to supplier but $1000 for a turbo charger is out of my league.
