I recently removed the engine from my 91 Turbo, and installed a rebuild. I had it towed to the dealer to fix an oil leak, and a bad sensor...but mostly so they could fine tune the timing...etc. The tell me the car will not idle under 1500 rpm. He said that if I try to drive it home, the car will overheat at a traffic light or other stoppage. Is that the case? Can our cars overheat at a traffic light at a 2k rpm?

 

It is possible it will overheat if you are reving the engine sitting at a light..

I would say it's possible, but not likely, unless you are stopping at everylight.

I would think the car might start to get hot, but as soon as you get a green light, the car would cool down when you started moving again.

I guess I would wonder how far you have to take it.

Even when my car would overheat very easily, I could still make it from the dealer or friends house back to mine without major incident.

you need to get a more specific diagnosis, why does it overheat?

sounds like there is a vacuum leak and the timing is way off.

did you also forgot things like the under covers, fan, etc.?

 

He said that there is a vacuum leak, but he wants several hours of labor to find it. Something that I think that I can do. The fan's fine. He just said that if I have to rev the engine to keep the engine running, then I would overheat it because of no movement.

 

You get the best cooling from the fan when the engines at 2000-2500 RPM.

Just run the damn lights!!

 

1 hour of shop labor: 40-60 bucks.
1 tow from the dealer to your house: hopefully less than 60-75 bucks.
Being sure that, by towing it home, you won't overheat and blow the motor? Priceless (or thereabouts).

 

It definately sounds like what happened to mine. after an engine swap i had a vacume leak that caused identical problems. i think that if the vacume hoses are original they get somewhat fragile and can't survive the trauma of an engine replacement, i.e. being moved around knocked against etc.
