[Vwdiesel] Lack of power, no smoke, good compression..

[B & R Decker]

Hi Clint;
	I would think that the pump is the last place to look. I have had
quite a few VW diesels and participated in the repair of many more. We have
never had to replace an injection pump to cure run problems. If one leaks
repair or replace it otherwise look somewhere else first for the problem.
You state good compression in the subject line but if you haven't done a
compression check that is the first place I would look. IF the compression
is good( VW says it should be 398 to 483 psi ) you have a motor to work
with. If the compression is bad it is time for a rebuild. You might have a
burned exhaust valve or even just a bad adjustment if it has mechanical
valve adjustment. One of my best investments is the money spent with my
local diesel injector repairman. From idle to full bore perfect injectors
make a huge difference. Check to see that your idle is set to specs. A wrong
idle adjustment messes with fuel delivery. A lose adjustment of the throttle
cable could be your loss of top end power. Another thing that sometimes
gives trouble is the rubber grommet that is in the throttle pedal They can
get mushy and even let your throttle cable fall out.

I think my pump is starting to get weak on my 83. I
have not done my injectors yet (thanks to everyone
with ideas on removing the injectors, the o'rilleys
socket is perfect :) ) but I am noticing my car is
having troubles keeping highway speeds. Pulls good in
lower speeds but stumbles a bit a very low engine
speeds and has slight "power surges" just off idle
(like I put it to the wood) I am starting to loose
speed going up hills at 60 MPH that a few weeks ago it
was doing just fine.

I have replaced the fuel filter in the past 3 weeks.
