Hey guys any advice on these problems I think I am having would be alot of help. First would be excessive "pinging" from what seems to be the exhaust shield right after the headers. I was wondering if this is normal, I have never had a car ping this much during or after I have parked. Another problem that arose tonight was when I was racing my friends Legend (and yes I spanked him ), after hiting 140 mph the oil light came on for about two seconds, I slowed the car and have not seen it since. I checked the oil and it was on the low end. Another problem would be that the Air Conditioning seems to be on the warmer side on "cold." We had a hot day here in NorCal and it could have been cooler. The wierd part was that the passenger side was blowing colder air than the driver side. I don't know of any split AC and the vents were all the same. ??? The history on this vehicle is that I purchased it about three months ago with 130k on her and put pure synthetic oil in for the first change. I know it's thinner and all but the previous owner had an oil receipt and he used the regular stuff but when I checked the oil level it was also low. Both oil changes were done a Jiffi-Lub. I don't run my Lex hard all day at all, I enjoy cruising but when I do get on it..... well frankly sometimes it's dissapointing compared to some of the threads I have read on the forum. I can't peel out of the line, and it just seems more like a 16 second car. I have never done a tune-up but it is in the near future. Any advice will be much appreciated.

 

Well the pinging noise I THINK is just the water coming back from your water pump and it is dripping back into the engine, as well as probably other fluids returning to their resting spots......... And it seems the longer / harder you run your car the more it seems to stick out, at least to me............ As to your oil light, One day I was backing out of my driveway it came on for a split second then went out, I thought nothing of it, when about a wk later I was on my road trip down to SC and it came on a few times when I was in the mountains and when I was at higher speeds, I was thinking it was doing like what a GAS light would do if you are on a steep hill and if you are on it long enough your GAS light will come on until you level out your car again because the car is thinking you are low on gas when it just unbalanced for that time. Then I got to thinking that gas sits in your tank as to where oil is running thought your car as it is running, and while I was on my stay in SC it seemed ever day it got worse and worse as to the light coming on and staying on, I was then getting worried, and as soon as I got back into town I took it to my shop and I had then flush the coolant and do a transmission fluid and with the transmission flush they did a oil change also and from that day on my light has not came back on, also I was thinking maybe the car knows when you are reaching the 3k mile mark for your oil change and the light comes on to remind you to have it changed, from the time I had gotten the car and from when the light started coming on it was about 2500 or so miles that I had put on it and I am not sure when the oil was changed from the original owner.


Hope this helps....................
And please correct anything I may have stated wrong.............

The excessive 'pinging' i get appears to be exhaust ping - which usually comes from heat stored in the cats and the use of dissimilar metals in the exhaust system (aluminum, high carbon steel, etc.) expanding and contracting at different rates. Porsches and Corvettes do this and assumed the same for the SCs, but if I'm wrong and other SCs dont do this, let me know!

Having the oil light flash during high speed runs is typical if your oil supply is a little low. At high RPMs, the oil pump is trying to scavange oil and as the oil sloshes around, it may miss some causing momentary low oil pressure. I also had the oil light flash during high speed 'interludes' on the canyon roads with Carreras and Mustangs and found that keeping the oil level to the highest level prevents this from happening.

No idea about the A/C other than getting it recharged given you have the miles you do.

There seems to be alot of SC owners in the Bay Area. We should organize a tech meet (the weathers been awesome lately) and do a group tuneup, changing the belt, plugs, wires, filters, etc.; I'm about due for a tuneup too and those dealer prices are ridiculous and wouldnt mind doing the same with a couple other SC owners.

Otherwise, I hope I catch you on 680/880. I dont find enought SCs pushing the throttle like they should!

 

My exhaust also pings quite a bit on warm up and after I shut it off. I assumed it was as Sarita911 stated with expansion and contraction. Not a big deal( I don't think)
