Is it very simple to do the piston rings on a 240dl with a b230 motor
and on those cars is there any way to change the transmition oil on the manual trans.

 

It is NEVER easy to do piston rings, on any car.
It is quite easy to change the tranny fluid-just drain it, and gravity fill it until it runs out from the fill hole. Just get a cheap gravity pump from any parts store.

 

Seeing you asked those two questions together I'm going to assume you know nothing about how to work on cars. I would suggest taking it to a shop before you make a costly mistake.

 

Well put sir! I didn't want to be so blunt...

 

well i have rebult the whole top end of the motor from blowing the head gasket and due to that it has caused a leak in piston 2 on the lower end
The manual trans i just need some ieads really on the best type becuse i work at autozone but they discriminate me for driving the volvo

 

A leak in piston 2? Like your blowing smoke, or you have low compression, or you performed a leak down test much to your dismay?

 

when i remove the plug wire to piston 2 the motor stays idling at the same rate to were if i removed the 1st one it drops

 

That doesn't necessarily mean you need to replace the rings in that cylinder. You didn't notice the motor was missing prior to pulling that plug wire? It could be a handful of things not causing it to fire on that cylinder. You need to perform a compression or leakdown test. What was the condition of the plug when you pulled it?

 

The plugs are brand new platum autolites ill check with the tests and see what i could do i ran a 10 40w oil and restore in it at the oil change and it seemed to help i also ran sea foam

 

Naa, I think you're on the right track with the piston rings... Go for it and replace them all, it's easy. Post pics.

 

The piston rings on a Volvo aren't any more difficult to replace than those on any other car. You know the procedure, do a compression test to find the cylinder with the bad compression (if the one you suspect is only like 10 PSI off the rest then bad compression is not your problem) and definitely do a leak down test to find out if the leak is or is not between the piston and the wall of the cylinder before you take anything apart, unless this is a particularly high mileage engine it is more likely the valves leaking. Also when dealing with anything mechanical, remember it is most likely that the culprit is that which you messed with most recently, in this case the head gasket.

The transmission fluid goes in the same way it does on almost all manuals, there are two plugs you can unscrew on the side. I'll say this being as the others have suggested that you may be inexperienced, let the transmission cool down first. If it's an M45/46 I think it takes ATF. Recycle your old fluid.
