yep...but it does work good in higher mileage cars. It is "for" diesels becuase of the very good cleaning detergants and additives needed for dirty diesel motors. But as I said...IMO...it is simply the ticket in higher mileage cars. Your internals would be immaculate after 3 changes

This is just ridiculous.

You know.... I never thought about that but now that you point that out that's a very good idea! I was about to switch the porsche over to amsoil(bought enough filters and oil to last me a few changes already) but I might run a change or two of rotella through there to really scrub her up first.

Coolants fine. Check under the drivers side dash next to the stereo, there is a little metal rod, about 2-3 inches in length, about the side of a 4-5mm hex key in diameter.

Its jammed up in there, because when it falls, the heater blows on full hot. There is a little plastic clip that connects that rod to a metal arm that pivots when the temperature is changed on the dash.

I didnt clip it, I just stuck it up in there.

bigdeano

His isn't blowing full hot... sounds like he doesn't have heat period.

Rock

Yeah because I jammed the clip up into the dash. Its being held on something. Its now in the closed position FULL COLD. Regardless of what the temp on the control says.

Find it and drop it down, youll get really toasty really quickly.

Rock

Look for that under the drivers side dash.

It was summerish when I last touched the car. I didnt need the car to be blowing 90 degree heat in the summer.

I just stuck it up in there while I was driving because I was getting really warm. For the heater to function correctly, you will have to get a replacement clip.

bigdeano

I see what you're saying, my bad. Yeah fix that clip and you're good to go once you get it aligned properly.

That was before they changed the formula. Use to have more phosphate in it, now has very little. Use 20-50w motorcycle oil, contains more ZDDP. Read the recent article in Panorama, lots or good oil info in there.
I switched to Brad Penn and my oil pressure went up and no more oil leaks. Use to be a big advocate or M-1, not anymore.
Also, don't change your oil every 3k, that is the new "no-no". Most oils don't reach their peak in lube effeciency until 4 to 5k. Would that be why new cars don't want you changing the oil till much later? Duh!
FYI

But thats for an early 944 with the cable actuated heater isnt it? Later 944s open the heater valve up with vacuum

bigdeano

Both of my 86 951s have those clips in there that hold that rod in place. (referring to picture above) Vacuum may be what moves that rod, I honestly don't know, I just know that the position the arm and that rod are in dictates hot or cold air blowing out the vents. Normally when a clip breaks it fails to hot air, unless someone has pushed/positioned it to blow cold as mentioned above.

So I went under the dash and I see the cable but what do I do? just pop it out of the white plastic clip?

0w/30....erghhhh.....
