Question about 1991 Porsche 911

1 Answer

I just purchased a 1990 911 C4 with 66k miles on it. It had some work done to the oil lines before I bought it to fix some leaks etc. Overall the car runs really well with one exception. When I'm sitting at a stop light for more than a minute or two the idle drops and the car will seem to lose power and stall. The only way around this that I've found is to continue to keep the engine revving around 2000 rpm? Help please.

Engine burning oil


you should be checking the Oil Level more often than 5K miles but my 2009 Toyota Corolla burns oil (Not a LEAK), just consumes oil (1 Quart every 2K miles). It has done this since it was Brand New and Toyota said (ADD MORE OIL).... So that is what we have done. Watch the level and make sure you add more.

REPLACE SPARK PLUGS AND WIRES, REPLACE DISTRIBUTOR CAP AND ROTOR. NEED CHANGE ENGINE OIL AND OIL FILTER.YOU NEED CHANGE TIMING BELT HAS TO BE CHANGED EVERY 60000 MILES TIMING BELT CHANGING TIME OVER DUE.REPLACE WATER PUMP WHEN YOU REPLACE TIMING BELT BECAUSE TIMING COVER HAS TO BE REMOVED WHEN YOU REPLACE WATER PUMP ALSO GET BOTH DONE SAVE TIME AND MONEY.CHANGE TRANSMISSION FLUID AND FILTER.REPLACE FUEL FILTER AND AIR FILTER.FLUSH COOLANT SYSTEM REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP HAVE GARAGE FLUSH OUT BRAKE SYSTEM ADD NEW BRAKE FLUID.INSPECT BRAKES HOSES CHECK FRONT BRAKES PADS AND CHECK INSIDE CALIPER FOR LEAKING SEALS CHECK REAR DRUM BRAKE SHOES CHECK FOR LEAKING WHEEL CYLINDER SEALS.CHECK BALL JOINTS AND STEERING LINKAGE SEALS.CHECK DRIVE BELT OR BELTS.CHECK POWER STEERING FLUID LOOK OLD DIRTY HAVE GARAGE CHANGE POWER STEERING FLUID.ALL THOSE THINGS HAS TO BE CHECK AND DONE IF LAST OWNER NEGLECT DID NOT TAKE CARE OF VECHICLE.ITS GOING TO BE A EXPENSIVE COST. JUST DO A LITTLE AT A TIME.THE TIMING BELT WOULD BE MY WORRY IF IT BREAKS ENGINE IS DONE.I WOULD REPLACE WATER PUMP AND TIMING BELT FIRST WOULD DRIVE MUCH UNTIL THATS FIX.

Just bought a used 1996 Honda Accord 4dr 6cyl and it has a major oil problem. when not even on it would leak oil. the car ran out of 5 qts of oil in a 50 mile drive. noticed the oil filter was 1/2 inch...


Yes there is. if it leaks, find out where. You may have engine damage from running the car out of oil. You say it leaks from the oil pump, same as before? was the oil pump replaced? Sounds like a pressure fed leak, so it should be easy to find.

Loosing oil in 06 impala SS


First, do you see oil leaking on your driveway? Have you looked under the car and checked to see if any oil is dripping?A rear main seal will drip down the front cover plate of the transmission sometimes from the inside, appearing like a front seal leak on your transmission but the oil will not be red fluid you would expect if that were the case. I would not worry about rear main unless you see a leak there. Look your entire engine over and check for leaks everywhere. Several small leaks can add up to an overall large oil loss. Correct the larger ones first.
Generally all seals will last far longer if you change your oil frequently using a good quality lubricant. If you are loosing some oil, use one of the oils made for high mile engines. I suggest you use a mild additive like marvel oil 1pint with every oil change...it removes sludge, carbon and varnish buildup without the drawback of knocking it loose all at once, where it could plug up your oil pump screen. (it also smells good) Change oil every 3000 miles for the first three or four intervals, then consider using a good synthetic oil. Synthetics far outperform any other lubricant in every area! Avoid overheating your engine...overheating does more damage to seals than any single other item...When seals get very hot they harden up, crack and fail.
Good luck with your car!!!

250,000 miles is a lot, although for a properly maintained Honda it could probably go many more. With any high mileage car purchase, you always run the risk of something happening, major or minor. I would ask the recent history...what has been fixed or replaced in the last 50,000 miles? Also, with any oil leak, there's the chance that it is making a bigger leak, although with a engine with this many miles, thats not uncommon. I would just monitor the oil levels carefully. You don't want the engine to seize.
One last thing, check out www.carsurvey.org. You can look up any make and model and see what real people who own the same car think and what problems they have had.
Good luck in your decision!

Oil leak and oil burning


if your oil burning is upon start up then i would suggest you get your valve seals replaced while you are getting your valve covers done if its a non-stop while it runs then its your rings if you opt to get the valve seals fixed you would be looking at probably $250 but your gaskets would be included the deciding factor for me would be the amount of oil consumption and how much i would save in the long run good luck
