check engine light, '88 5jkcstq (low on oil?), and type 44 comments

[auditude at neta.com]

Hi Folks,

I noticed that my oil level was around a half to three quarters of a 
quart down, the day that I saw my check engine light come on a 
couple times.  After I topped it off, I haven't seen the light come on.

Maybe that was it.  It's my understanding that the check engine 
light is only for the knock sensor, and knock sensor codes are not 
stored beyond turning the key off.  So, I guess unless I see the 
light come on again, the symptom is gone.

What type of tools do I need to verify knock sensor torque?  The 
SJM website says a crow's foot socket is required.  What size?

It seems like if the check engine light comes on with the key on, 
engine off, then the system is working correctly, unless the light 
comes on while driving.  And also, the only thing that would cause 
it to light up while driving is either knocking, other knock-type 
noises, or a defective knock sensor.  Is this right?  Whereabouts 
are knock sensors on the price scale, anyways?

This Type 44 turbo stuff is pretty cool.  I'm a bit surprised at how 
much fun I'm having with the car stock.  I can't wait to see and feel 
1.8 bar (which will probably show as 1.7 on my car, since it's 0.9 
bar with the key on and engine off, and I only see 1.3 max).  I need 
to get a bypass valve in there, strap the intercooler, and get an 
aftermarket boost gauge.  Is there anything else, besides a 
potential wastegate or schrapnelknobben mod?

Is anyone selling any aftermarket/performance parts for my car?  
How about a leather shift boot that is in good condition?

By the way, I can still feel the gears catching slightly when I shift.  
I'm thinking this is not right.  I guess I'll check the engine/tranny 
alignment via the mounts, but is there anything else to look for?  
Low fluid, out of adjustment, or worn parts?  I can deliberately 
make it not catch the gears, but it's not natural or preferred.

Thanks,

Ken
