i dont follow this... if these cars like to RUN, why wouldnt you want to drive it daily?

Arrwin

I interpreted "daily" as daily commuting in stop and go traffic and short trips where the engine doesn't get to fully warm up. I would think daily driving in high rpm situations w/o much traffic and stop-n-go would be the best case scenario, but that is not an easy task w/ most of us living in the bigger cities.

There's nothing wrong with 2 heat/cool cycles daily. Why does it matter how many heat/cool cycles happen in a day? I drive mine 4 or more days a week and that means 2 cycles at least each day. I feel it's important to take it to redline a couple times every time it's warmed up to blow it out a bit. Use the damn car and drive it hard. Use from frickin' techron and ENJOY IT! ........i never understood the philosophy of owning something so fun to drive and only driving it once a week. Wht buy the damn thing in the first place. Go get a fine peice of art and hang it on your wall instead if that's your philosophy.

Arrwin,
Good point. But a little stop and go isn't going to kill the car. Fortunately my commute is on the freeway typically with some room to run a little. Unfortunately I get caught in it from time to time. That doesn't mean I'm going to stop driving it.

If Truspeed is gonna step up and pay for a top-end rebuild, I would be very happy if I were you, especially if Hergesheimers is gonna do the work. They did a similar thing for Agro when he bought his car. https://rennlist.com/forums/showthre...light=truspeed Think of it this way, you will know that your top-end is solid and the bottom end of these cars are supposed to be very robust. I would be very impressed if they stepped up again.

Good luck.

There is a very good DIY article on this I believe on Robin's site. I can understand not wanting to deal with this as soon as you get the car, but it's becoming less of a big deal, if SAI ports are the only cause of the CEL. I live in a horrible traffic area and had to take the 993 to work yesterday to drop it off at a shop for the clear-bra install. I still managed to redline it every chance I got. I don't care about gas mileage. I care about smiles per miles and beating the hell out of my car. I have found on all three of my 911's that the harder I drove them, the better they got.

Truspeed took her to John DeBonis Imports for all of my work (steering rack, CEL diagnosis and fix)... ever heard of him? Truspeed says he's "great".

I've not heard of that shop, perhaps others have. When Truspeed says they will "fix" the CEL problem, does that mean a chemical flush or a top-end rebuild? A chemical flush will clean out the SAI passages. If your valve guides are worn, you will need a top-end rebuild. Do you know how much, if any, oil you burned in the time you have had the car? This is the primary indicator of worn valve guides.

If they are gonna pay to do top-end work, make sure you find out which machine shop they are gonna use to redo the valve guides and find out from that machine shop what type of guide materials they are gonna use. OEM material is unacceptable as a replacement. Check some of Adrienne's threads as she recently got top-end work done or search through some of Steve Weiner's threads as he is the guru. FWIW, I believe Truspeed paid for top-end work for Agro.

Father, you have a PM.

ok...yep, got it.

i live in dallas...the land of big highways and spread out suburbs/cities... my car gets to stretch its legs for at least 30min everytime I start it...

I have not experience CEL - well at least yet. I use Techron every 2K miles. I normally drive my car at least 30 minutes for any trip, and oil thermo is open. I plan switch off to BG as this chemicals may provide bit different cleaning action.

dhicks

What is Techron...I thought it was something in gas from one of the major oil companies...do I understand there is an addative called techron?????

dhicks

OK just went and looked it up via google....I cant see that this will do anything for the SAI....????

Mark in Baltimore

A Chevron product available at your local auto parts store and recommended to be mixed into the gas tank before an oil change. Running the car hard (ie. drivers ed events) can help with Techron's cleaning qualities.

More threads in the archives on this subject than you can shake a stick at.

Arrwin

Haha...that's the complete opposite of what I have here. Haha.

I know the temp is a factor as well...how hot does it get there (extremes)? What weight oil do you use?

I thought Techron should only be used a tank before an oil change so that during the oil change, all the contaminants will be drained, unless you change your oil ever 2k miles(?).

Is it beneficial to use Techron more often, rather than just before oil changes or will is there no benefits since the contaminants are still floating around in the system?
