For the TII, what typically are the signs and symptoms prior to the seals and other internals going kablooey.

 

Idle problems and stalling out.

 

compression

 

I have an idle issue but at idle my vac pressure is at 10 instead of 20, would the a vac leak not motor goin out right?

 

There are none.
When a motor gets hurt, it's instantaneous.

not necessarily, bearings failing will usually cause some clanging or rattling noises..


but bearings failing is a rare death for a rotary unless you happen to get metal in the oil.

 

Champagne bubbles in the coolant filler neck at cold start up is a sign of water seals failing.

 

I seem to remember reading a few stories about peoples 7's running really well the day it blew its motor (Apex seal failure)

 

That's because leaner air-fuel mixtures give more power.

They also cause detonation.

 

man i like ted he seems to know every thing

ted your awsome

 

Hot start problems....if your injectors are not leaking it is a sign of low compression.

thats depressing.

 

lol, just like in living creatures, before they die, they usually have a shitload of energy and such just before, then they die.

 

You can expect the oil to become abnormally dirty just before the side seals blow. I know!!!! I can atest to the fact that it doen't take long for the engine to go after the first symptoms.

 

agreed

 

This is depressing. If anything, I'd like a little bit of reliability but then again, what can you expect from a 15+ year old car.

My car has been bucking unexpectedly at light loads. It would happen once then nothing for a while. Just recently, it bucked three times consceutively. The car is now parked until I either rebuild it or replace it this winter.

On top of the bucking, hunting idle and fuel leaks abound. This car will need a lot of work. Oh, well.

 

I second this, my last engine went during a race (beating) with a supra
