[Vwdiesel] Compression check with Hyd lifters and Alum head

[Bart Wineland]

I'm curious since I just did a compression test on my '89 1.6 na hydraulic 
if pulling all the injectors is to just make it easier on the 
starter/battery or if it also affects the reading? Of course when I did it 
I did it the opposite way buy pulling one injector at a time and replacing 
it before going to the next. I did let it crank each time until until there 
was no more gain on the gauge (8-10 revs). Are my results skewed because of 
the way I did it?  My numbers all came in low at 350-385 and now I wonder 
if I should redo it.

thanks,

Bart
