So I took off the manifold and cleaned up the EGR and got it working OK
(at least it opens and closes with vacuum, not sure if the car systems
are working to make it do that). It was throwing EGR and glow plug
codes, I read some other reports that suggest the EGR might somehow lead
to the generation of GP codes, so if that is the case then I probably
wouldn't need to fool with the GPs. Not sure why bad GPs would make the
car run bad once it starts anyway, it starts mostly OK with a good
charge on the battree so that suggests the GPs might be mostly OK too.
There is also a bypass method to jumper some wires on the EGR so it
won't be EGRing and doing all that business, I might do that too if the
car still doesn't run right.
I have not put the manifold back on yet, I was waiting to get some Kroil
and keep dosing the GPs with it, but the suggested procedure is to run
it and get it hot to make them easier to get out, which means the
manifold needs to be on there for the car to run, and it would have to
come off a hot engine which would not be a lot of fun, but it is mostly
easy except for the clamp holding the turbo output tube onto the manifold.
Albore's LIST MOM's opinion aside, I guess I should just put it back
together and see if it runs better now, and if it does then not fool
with the GPs. I'd have to do that anyway, so I guess I will.
BTW the EGR was completely buggered up with diesel soot and crud, took a
lot of scraping and brushing with little wire brushes and degreaser to
get it clean. I put some purple degreaser stuff in the manifold and let
it sit for a coupla days, not sure that loosened anything out of the
manifold, but I managed to scrape some stuff from the ends I could
reach. What I poured out was pretty nasty though, so maybe something
came out of it. If I had a pressure washer I probably could have
blasted a lot out. It is not completely clogged so I think it will be
OK. The EGR concept is completely stupid.
This was something of a pointless sharing, but I guess it got my
thinking thought through.
