Hello everyone I have a question about my 70 Challenger R/T
on the way to a car show my R/T started blowing a lot of white
smoke from the tail pipes and water also so I brought it back home
and was running real bad like trying to shut off luckily made it to me house
and was wondering what could be wrong with it before I tow it to a specialty
shop ? Any help will be much appreciated....Thanks in advance.
P.S... it has fuel injection.

Check your oil pronto!
SB or BB?
Compression test with all plugs out. Note plug conditions and respective cylinder.

It could be a blown head gasket or cracked head.
Probably best to tow it to the workshop.
Don't try and start it in case it leaking a lot of water into the cylinders.

I once accidently put diesel in the tank and IIRC there was white smoke, and it ran poorly BUT I'm pretty sure there wasn't any water coming out of the tailpipes. I'm leaning towards head gasket too in your case.

The other thing I saw that an engine blew white smoke was it had a leaking master cylinder and the engine was burning brake fluid. It was sucking back to the engine from the brake booster.
The smoke did smell a bit funny.
If your engine is running badly it does point to something that may be quite serious.
Best of luck.

Definitely time to start looking at the engine oil for water and oil in the radiator. Pull the plugs as Daves69 mentioned. If your lucky it's only a blown head gasket or sucking brake fluid from the brake booster because of a bad master cylinder. Best of luck times two.

I had time to check it today and the oil looks clean antifreeze looked good! So could it had been the Head gasket?

Cylinder compression check as mentioned will tell you something. On a cylinder leak down check with a gauge, if the cylinder bleeds down..... may tell you where the problem is.

Did you pull the valve covers off? A lot of time the water steam in the motor will go there as it is usually the highest place in the motor. Steam rises and it will end up in the valve covers a lot of times.

Definitely could Still be a head gasket. Both compression and leak down tests would must likely confirm this.

I agree take it to a good shop and let them tell you what is wrong with it.
Probably cheaper and easier.
