Should I have used the old torque convertor on the new transmission? Or it doesn't matter? Cause mine is a 1999 and it's a 2000 trans.
I wonder if the torque converter is seated into the trans.

In an IC engine the piston rings don't seal 100%. More like 99.9%. In normal operation a little oil is burnt off as it sticks to the cylinder wall when the piston goes down. At the same time, combustion gasses blow by the rings and make their way into the crank case. The CCV system scavenges this mess by allowing the engine to suck up the gasses again. If it wasn't there at all or completely clogged you get a lot of slobbering out the dipstick and all manner of interesting leaks.

However the CCV is only sized for normal operation of a healthy engine. When the rings are shot way too much gets past, and the engine ends up consuming oil at an accelerated rate. As well the hot gasses result in more oil vapour which starts showing up in the intake.

A compression test will confirm whether your rings are done. If it does, there's the problem. Valve seals will let oil into the combustion chamber but shouldn't show on a compression test.

Dry test first, then wet test. CPS unplugged with throttle blocked wide open. 3-5 revolutions per cylinder.

For 35s, 98, aw4, what's the best gears for the best mpg? It's my DD and will probably be 70 highway, 30 city. I've heard everyone say 4.88 but won't the engine be turning to fast say at 65?

How accurate is this "write up"? http://troubleshootmyvehicle.com/jee...-compression-2

Do i need to remove all 6 plugs to do the test on one cyl? It shouldnt matter though...

For the wet test just add the oil in where i pull the plug out?

Attention CB gurus.

Is it OK to set up my antenna like this, using a spring with female connects at both ends and just hook up the coax connector straight to the bottom of the spring?




I ask because every setup I've seen with the coax connector has the double nut thing in between the mount and the spring like this one.

(I'm not assuming it works just because the Tacoma guy did it.)

Yeah while waiting for an answer. I texted my friend jake about the situation. He told me to make sure the slots on torque convertor aligned to engage the keys on the shaft. So I got it seated in and finally got all drivetrain supported back on crossmember

So it's working okay? That was the "click" we were discussing.

Default Left front shock

Who's the genius that decided having the top of the left front shock directly under the brake master cylinder, was a good idea?

I was hoping to be able to use a deep well socket and my 3/8" drive cordless impact like I can on the left side but NOOOOOOOOOOOOO.
