IMS Replacement... The Jager Saga

[tonycarreon]

wow. very interesting. i had to go check mine to see what was up.

at idle, no change in deviation - stays at:
1: -8.88
2: -5.64

actual angle:
1: -0.33
2: -0.28

during drive @ 3k RPM (i didn't check actual angle) the deviation moved to:
1: -8.98
2: -5.69

i love this forum - i learn something new every day! and jager, thanks for this awesome thread.

More than 3 degrees difference between banks on deviation... Not sure what the specifications are for timing difference between banks are but you might want to take a close look at this. I'm sure performance is not optimal.

not a lot of info out there, so maybe someone else can chime in. from what i gather the "acceptable" deviation is +/- 6 degrees on each bank, no idea as to what is acceptable difference between 1 and 2. i am sure the pads are worn out seeing as the car is 10 years old and has 85k miles on it, no work has been done in regards to the timing system.

By pads do you mean chain tensioner pad wear giving more cam chain slop and loss of motion on cam shafts?

yeah the ramps/tensioner pads on the variocam solenoid - though all the pictures i've seen of them show them as a brown color and the bits in the filter were black and rounded. so perhaps the chain guides as well. can't imagine both of them are fine after that many miles / years.

Jager, great work and great pictures!

Hope to have some time to get back to my 2001 "project".

Thanks Paul... I was wondering how far you had gotten on your motor issue. Since you are tearing it down, are you going to ship the IMS to LN Engineering and have them do the bearing upgrade??

I found black bits in my filter and thought they were tensioner guide material but when I put pressure on them they crumbled like carbon.....carbon deposits released by my spirited driving perhaps; they were roundish small bits ....quite a bit actually. I am not really sure what they are

....couple of green copper specs along a few silver metallic specs which were cause for concern
