PROBLEMS 2000 Boxster S
2000 Boxster S
Problem 1: At start up either cold or warm the engine emits white smoke and sometimes a white/blue type smoke. I thought this was typical for the car but now it does it much more than just random. The other dayat a stop light (car was warm) the light turned green and the whole block filled with smoke; it seems to be getting progressively worse. Problem 2: A loud “squeaking” noise coming from engine. It sounds like a belt noise but the belt was replaced along with the alternator and the noise is still there. The noise does not get any louder when the engine is reved and seems to go away around 3500 rpm while driving. Once down to idle to noise comes back. Problem 3: Car seems to run a little hotter than in the past. From what I can remember the car would run at approx 180 -185 on the highway and go up slightly at idle. The car is now running approx 200-210 range on highway and may go up approx 5 degree at adle. I think that a piston ring may be bad but I really don’t want to jump to any conclusions at this point. Any advise? Thanks Edgar |
All your problems could be related to the same issue, but each sounds like something different to me. Possibilities include...
1. Oil Separator has gone bad, allowing oil to accumulate in the intake, hence the white and blue smoke. Try opening the oil fill cap when it's doing it and close it again to see if it goes away. Turn the engine off first to keep from getting a check engine light if you like. If this alleviates the smoke, it's the separator. 2. Could it be that a pulley is worn and you simply don't hear it at certain rpm's because of other sounds from the car? You should have a mechanic ride with you and hear it firsthand. 3. When this high temp stuff happened to me, I discovered that my primary radiator fan died. To check your fans, bring the car up to temp, park it running with the AC on full blast, and walk to the front of the car. If you can feel hot air blowing from the fans just ahead of both tires (under the front bumper) they are working and there is another issue. If one or both are not working, it could be a fuse, or something else. Hope this helps... I'm just taking a stab at what I've learned and experienced, so the real causes may be completely different. However, these aren't completely off the mark as possible causes. |

Any insights anyone ?? |
Take to a mechanic now
With that smoke coming out of your engine the squeak is the least of your problems. This sounds serious. Don't waste time asking questions on the forum take it to a qualified Porsche mechanic now. The Boxster has 3 piston rings, two upper compression rings and a lower three-piece oil scraper ring. Either the compression rings or the lower scraper ring may be shot and letting oil blow by and burn. Soon your CATs will be ruined so don't wait get it fixed now before it becomes any more expensive to fix. This would also explain your high engine temps as the pistons are not getting enough oil. Eventually they will sieze up in the cylinders. This is only one possible reason for your problem. It could very well be something else.

If you don't know how to check the above things, take it to a qualified Porsche mechanic. Have him check the AOS and replace it if it even looks at him funny. If cleaning out the radiators doesn't help the operating temperature, have him check the fans, including the engine bay fan. |
You could have two or three different problems here.
1. White smoke from the exhaust in great amounts indicates coolant burning off. Has the coolant level dropped? Check the expansion tank in the rear trunk. While you're there, pull the dipstick and see if there's any evidence of water droplets or "milky" oil on it, indicating coolant mixing with oil. Blue smoke from the exhaust that smells like oil burning is an indication of possible oil seperator failure. 2. The squealing you hear could be a pulley, a bad water pump, or a failing oil seperator. 3. Your car running hotter could be due to blocked radiators, low coolant, or an air bubble in the coolant jacket caused by leakage. I suppose it could also be caused by the water pump failing. You should get your car to a qualified mechanic ASAP. |
2000 boxster
HEY I HAD THE SAME PROBLEM With the white and blue smoke. Its just The OIL SEPERATOR. I had it checked by two different porsche dealers as well, so i know it is. My car runs fine now. Also the heating problem is pretty normal on boxsters. It does tend to heat past the mid level, but your fan should turn on, and it will gradually cool. HOPE this helps!!! :)
