I had a failed fuel injector on the rear rotor and drove that way 50 miles to get home. Both rotors still had compression but the 2nd one might as well have been dead. The car will be slow as hell and low on power if you can get it to run.

There are two problems.
1) You're not going to have any power, so if you have to go up hill you can forget it.
2) Guessing that it's a blown seal on one of the rotors. You risk damage the rotor and housing by what's left of said seal.

If it'll go 10 miles I think it could make it 150 miles. I'd be more worried about being about to get it started and have it stay running.

Man he's so right. If your going to buy a brand new rotor, intermediate housing, and front housing, or rear, wichever rotor is dead, then go for it

But in reality, I'd be willing to pay the 100$ or so for the tow truck to get her home.

If u want to drive on one rotor, u HAVE to unhook injector connectors for the other one which does not have compression. If u would not do that, lots of unburnt fuel will go to exhaust and 3 mile drive could make your complete exhaust glowing hot red from manifold/turbo all the way back to exhaust tips. Not safe.

If you have a friend with a big pickup, you can rent an auto trailer at U-Haul for $50. That's how I got mine home. Much less to worry about that way.

^^^ just did it last week when my water pump let go. I had to bring the car back from Valencia on a car dolly. I made sure and got one where you drive the whole car up onto. Paid $53.82 at U-haul.

do you need some help??

if it is premixed then the blown side will get no oiling without the injectors running right, i would imagine all the seals scraping by without oil is not a happy situation.

I couldn't drive any where when my rear rotor is making zero compression. But then again I have an auto tranny and everytime I put it into gear the engine would die

remember there will some compression at higher rpms. that rotor spinning as fast as it does is going to trap some air/fuel and it will combust when ingnited. Maybe that is how you go once started. But the APEX seal may be crunching around in there. For the price of a good used Rotor housing you can have a dolly $53.82

Fuzzy, Where are you picking up the car?? Where are you taking it too?

You can go as far as you want. If you can keep it running.

it all depends on what condition is blown side in (if it still makes full or some compression on one face (2 apex seals good) or if its completely without compression 2 or 3 apex seals gone.......in first case, u can drive, it can idle and will make power, in other, u wont get too far....

I blew an apex seal on the rear rotor in Atlantic City, then drove 175 miles to my parents house. Car had no power up hills, but on the highway drove like a champ at 80 mph. Burned two tanks of gas getting there, rather than the usual one tank it would take. Just dont let her stall. Itll be hard to start, major flooding here.

Wow, if that's the case I would rather rent a dolly or truck instead of driving it. It seems to be a much cheaper and safer option...

when i first got my T2 i drove it on prolly one rotor for about a half mile till i hit a hill, and i was stuck there. just stay away from any type of incline even just a small one it will not make it.

Are you talking about the s5 on teamfc3s? I saw that for sale a little while back, he said it was a 87 now its a 89 s5, sounds weird unless pics prove wrong. And your in ontario, i'm in riverside, vegas is ~250 miles away, it could possibly make it as long as you have a full tank and go nonstop, you could possibly get AAA to do 100 miles and do the 150, or do the 150 first then the 100 (so you can have the car running before you leave and be sure it stays running, not tow it, die and be stuck in the middle of nowhere)

luckily he is going down the cajon pass and not up, the 15 may cause probs, due to its constant changing up and down through the pass. and coming up by the state line there is some small inclined hills also. i wouldnt try it from vegas to ontario thats a 3 hour drive on blown motor.
