Pulled the Motor on my Q and im already just mind blow on its size and obnoxiousness. Trying to figure out what I can eliminate/re-route to clean up the mess of vacuum lines and what not. Also considering removing EGR which seems like it will help clear up a ton of stuff.

Ive done alot of reading but would love some detailed pictures if anyones got some. Also some good diagrams would help too.


Thanks in advance.

Look through every page, I know there are over 30 :squint: but it is mentioned quite a few times, this is what I found just rummaging though. You will also learn a lot about John Dixon, HLA's, and if VH45 internals will fit into a VH41 :rotflmao

Does anyone have an easy to read vacuum diagram???? Ive always found them for the KA and the SR but still for some reason haven't found one for the VH.

Gonna need to get rid of all this stuff. Plus I am looking to simplify since 1/2 the lines are s*** anyway, just want to get it cleaned up.

Being that they are both after the TB what is the point. ugh. 4 cyl is so much more simple.

learn to read the fsm and go ahead and order new timing chain guides as well as a 94+ fuel rail and injectors.
