Sunday 07/14/2024 | 1987 | 911 Carrera Targa | Transmission/Clutch
My 1987 911's transmission grinds a bit when shifting from 2nd to 3rd but only when the transmission is warm. (The PO had the same issue when he bought the car new in 1986 and the dealer replaced the syncros. The problem persisted after I bought the car in 1997 so I had my Indy attempt repair: replaced syncos, fluid change and bled clutch but no change). Over the years I've learned to upshift very slowly once the xmsn is warm but still a nuisance. Any clues? ...

A while back my 968 developed a loud squeal for the first few minutes from a cold start. This was originally noticed not long after my AC compressor was replaced. I sent that compressor back and got a replacement, it squealed also. The obvious thought it, it's the compressor, but 2 in a row makes that less obvious. This squeal vanishes a few minutes after the cold start. The AC performs great. When I had the car in for another job at the local Porsche dealer, the ... I've got about 25 k on the sparks and more on the packs.About 8 years time wise.Is OEM still the best? Or can I get more performance from something else. I've heard recommendations for Iridium plugs by NGK .Are there any upgrades on the packs over OEM?My engine has an X pipe on the exhaust tips, a tune, bigger throttle body, IPD plenum, and hi performance intake filters.No Headers/ 200 cell cats...yet. ... (1) My 1970 911T is set to idle at around 1100 RPM. While this seems OK - isn't the official RPM around 850 RPM -- "warmed up" or when reaching operating temperature? My mech said 1000 is acceptable. Personally, it seems after car is initially warmed-up after a couple of minutes, it's less prone to stalling at 1000 +/- vs 850. Any insight on this? (2) Also - I'm using premium fuel (91 Octane) - is this a waste of $? I don't see a performance difference. I used to go to a ... Ed, do you have a current flow diagram for a 1971 911? I'm trying to wire up a turn signal/headlight control and I'm chasing down the white and yellow headlight wires. I've run into this symbol for the yellow wire and I don't understand (see image). Does it indicate the junction to the fuse panel? If I had the current flow diagram I think it would be a help. As reference, I'm installing a 911 column and controls on my 1971 914. I'm nearly done and all ... I recently purchased a home in which our driveway is located on a road with a downward slope. The community has underground drainage so I have an incline going into my driveway which acts as a curb to keep water from entering. To make matters worse, the house sits lower than to road so the drive has a bit of a crown where it goes down towards the garage. I'm considering getting a 987.2 or 981 BASE Cayman and trying to figure if I'm going to be able to get it in the driveway.

I think I'm due for a clutch and I would like to do the IMS while at it. I'm looking for an experienced honest mechanic or shop in the Ocala, Florida area. I have an unexplained rattle in the front suspension. I'm familiar with finding tie rod problems and wheel bearing problems. I've had my car on my QuickJack and cannot find anything loose or clicking. I recently had the front end aligned at the dealer and asked them to inspect the front suspension. They found a bad tie rod bushing and replaced it. The rattle is still there. I'm baffled. I have a great video of the car rolling on a slight down hill road with the rattle undisturbed by ot ... The black ring that treads onto the ignition switch assembly has several small protrusions that are used to thread it onto the switch, but after reassembling it (the switch is inside the dash and the ring outside), it will not withstand the torque needed to twist the key on, and comes disconnected.Is there a replacement for this part with better mating threads, or a better solution? Have tried to reach over the top of the transmission with no success. Can not fill fuel tank fully. Shuts off at about 3/4 full. Looking for recommendations on audio installation shop. I have a porsche classic (pccm) radio I want to have installed in my 993. Thanks I've tried re-learning and still no help. PCCM+ works perfectly with the Bose system, only issue is the TPMS error. I have three questions.First is a follow-up to Panorama volume 806 Tech Q&A titled “2000 Boxster: Display”. I have the same issue in my digital clock/engine oil level gauge. Do I have to replace the entire instrument cluster or just the LCD? (This looks like a job for a professional.)Second, since I bought the car, it makes an intermittent singing sound which seems to come from the passenger side mirror. It does it at all speeds except very low speeds.&nb ... I recently had my 911T Speedo repaired at P A Speedometer (Bay Area). (MPH was fine - but ODO and Tripmeter didn't work). Probably broken internal plastic gears, They strongly recommended I replace my (old) current sheathed cable - as they predicted by looking at the cable seating -I could have future improper wear problems. (They did not see my car or cable - just the Speedo VDO Gauge they fixed), My VDO Speedo works incl ODO and tripmeter + reset. I believe they thought old ... First they moved wires around under the dash and said they had this reported as a problem by Porsche. Then the latest was they replaced the ignition; it was bad as it look like some of the contacts had been burnt. After each repair the car would start every time for a month or two, making me think the problem was fixed. Then It would happen again. When it happens, I attempt starting by repeating the start cycle; sometimes after repeating it anywhere from 2-3 times and as many as a doze ... Rear main seal is being replaced and I would like to have the IMS replaced with a DOF bearing. Where can I or the dealer get one? I think it would be the best solution. Dave Anderson The car indicates that it is learning but this has not changed even though I have driven more than 200 miles. Any idea how I can remedy this problem? My fog lights only come on when my high beams are selected. Attached is a photo of how my fuse box is wired. It seems like it should be a simple fix. Any advice is much appreciated! Looking for rear wheel stone guard suggestions. so many vendors curious if there are better ones than others. Was thinking a black carbon fiber look for a light colored car. What would cause this type of damage to the LCD screen?? The seller is saying it's faded from the sun but I'm not buying it. Upon completion and asked for $550rate for the alignment, I was handeda color screen shot of only the frontwheels, without the before/after full colorreport that had NO pertinent info on my Porsche or my name or VIN.Is this screen shot standard documentation per Porsche NA serviceStandards?FYI - car was driven by a junior tech off the dealer lot to a Audi dealer using Their Hunter alignment equipment. ... What is the maximum tire size for a 1987 944na Hi! I have a 1988 944S, that has what I can only describe as a driveline rumble most noticeable during deceleration in 5th gear from 60 to 50 MPH. It may also be heard in 4th, however it's harder to notice.It's most noticeable on deceleration, but can also be observed during acceleration - if I hold the throttle just so that it's "coasting" with no load in-gear, the noise disappears - as well as disappears when the clutch is pressed, and the car put in neutral.

Hi, everyone. My 996 came with a CDR-210 head unit. Immediately after I start the car its power cuts in and out at a regular cadence. However, if you let the thing warm up (which is odd for a radio) it works properly. Fuses are fine, connections are fine, but the problem persists. I figure this is probably a 25-year-old CD player on its way out, but I'd hate to lose it. Is there any hope of saving it? Something I may have overlooked? Thanks. ... My right side tail light doesn’t work. I have replaced the bulb and the wiring harness in the rear and the headlight switch cluster in the car and neither attempt was successful. Does anyone have a recommendation on what to check next? Thanks.
