No valve train clatter?

What made you check the oil pressure?

Do you have some actual readings? What were they?

No, but it is in the service manual:

Oil Pressure Measurement
Oil Pressure @2 000 r/min (rpm), Oil Temperature 90C (194F)

127 ∼ 167 kPa (1.3 ∼ 1.7 kgf/cm, 18 ∼ 24 psi)

If the oil pressure is much lower than the standard, check the oil pump, oil pressure relief valve, and/or crankshaft bearing wear and con-rod big end bearing insert wear immediately.

If the reading is much higher than the standard, check the oil screen first, and the oil passages for dirt or clogging. Also, replace the oil filter.

Its very simple . If there is oil on your air filter, you are overfilling the oil.
If your camshafts are wearing out , they are not getting oil. BAD.
Why is your rod bearing NOT wearing out?
You need to make darn sure those oil passages are open or you'll be right back in the shop.

It seems to me that labor should be there exspence as well if the cam wore out due to a hardening error. Thats a defective part, right? Be he same thing if your cooling fan ddnt work because of a improoperly install bearing in the fan motor when assembled I would think.

Assuming, for sake of discussion, that it's out of warranty being a 2008, getting parts only isn't too bad a deal, considering they're not obligated to do anything at all past warranty.

Start with the easiest thing first, when you get the engine all back together put a brand-new oil filter on it and run the engine and test oil pressure.

If that does not fix it then you have a problem somewhere that's clogging an oil passage beyond the pressure regulator.

Kawasaki admits and pays for all the materials but not for the labour.

Than we find out that also the oil pressure was musch to high. As a test we meassured another VN2000 and by this one the oil pressure was to high as well.

We communicated this to Kawasaki Japan and after 7 weeks they gave us the answer that they have doubt about the possibillities this is through and say it must have been a meassurement error of the kawasaki dealer. (He has been a qualifited exclusive Kawasaki dealer for the last 35 years).

When my motor is fixed next week Kawasaki Holland is going to take a new measurement.

My guestion to you all, Does anybody know about any problems with a high oil pressure? Or the combination between broke/disapearing campshafts and a high oil pressure at the vn2000?
Hi there

I think I'm running in the same problem. Do you have any paperwork from Kawasaki? I would like to use it to get paid for my parts too.

Anything is possible, but I doubt the camshaft issue is related to the high oil pressure. I tend to agree with your dealer that the camshaft is just a bad production product. Maybe hardening. Most likely that is the issue in my opinion.

I have owned a few cars that had "soft cams" and all of the models made that year or sometimes multiple years with that engine had camshafts that had the lobes flatten after so many miles. You just replace it with a new non defective one and the problem is solved.
