[Vwdiesel] cyl compression

[raymond greeley]

My mech. wants to do a compression test before we install new glow plugs, to 
make sure that the
hard starting is glowplug caused. since i purchased this 91 td jetta 18 
months ago i don't know
much about the cond. of the engine and think this diagnostic test is worthy. 
I am wondering though
what kind of numbers i should look for. the way i read bentley: new engines 
are around 493 with a wear min of 412 and cyl varience of 73 psi. The engine 
did and does run well and has started in this
cold weather i  am experiencing in chicagp. It does run on less that all 
four when started and
quickly evens out when i pull out the cold start handle. I use the cold 
start feature after it starts
as it seems to slow down the engine turn over if i initiate it before start 
up. I assume this indicates
a need to check timing, which will be done in the next maintenance phase. I 
look forward the some
points of discussion on these issues. thanks, ray
