Green rubber
 

Did an oil change over the weekend found these soft green rubber particles in the filer .RND replacment motor with 23k on it ? It was installed two years ago .Any Ideas what this is ? How bad is it ?http://986forum.com/forums/uploads02...1591144378.jpg

I hope it's the oil filter O-ring but that's very unlikely. It's more than likely the O-rings inside the variocam adjusters and there's no way to replace them. The same thing happened to my 37,000 3.4 after I installed it in my boxster. It's a common problem on very low mile motors that don't get used enough. New adjusters are stupid expensive. I went with used adjusters and lifters. My lifters went flat too.

Woody I bought this engine from RND IN 2018 I have put 23k miles on it since it was installed. 13 thousand a year, daily driver . They are supposed to have new variocam adjusters in these motors . I will check cam deviation tonight with my durametric software . Do I need to park it ? All the filter o-rings I have seen are black ?

I would check deviation, not drive it and call RND

Looks like I'm well in specs.? Any idea where soft GREEN RUBBER could come from. I did put in a tech support to RND.

VarioCam units.

RND engines thinks is CURIL T sealant ? Where do the o -rings go in the variocam units .Dose anyone have an exploded drawing that shows them ? If they come from variocam would it not cause the timing specs to be out of range ? Thank you you guys are the greatest ..!

Here's some great pictures from the link that I posted for you earlier (to save you the work of clicking and scrolling to look at it). It shows the green o-rings in a disassembled variocam in good detail.

Thank you 78f350 So it looks to me like the chain rail has to be completely gone for the hydraulic actuator to come out of its bore ? And release its internals. So I don't think I have this problem.I will check my cam deviation daily to make sure nothing is changing. Thank you all, this forum is an excellent tool.

That part is the only green rubber in the engine, and cam deviations at idle will not reveal it as it has no impact on those values. You need to look at the active cam angles after the VarioCam activates.

Can that be checked with the durametrics software ?

JFP, can you check them while driving on the freeway (with a friend) looking at the Durametric?
.

At what rpm dose the vario cam become active ? JFP in Pa can you please tell me how I can check this ? Or is this a dealer only Job. Thanks to everyone for there help .

What year is the car? Cam angle positions can be measured by the Durametric by simply revving up the engine, you can also track it real time while driving.

would be interested in seeing how this works out...the color is right for CURIL T, just wonder why it would show up after 2 years. Best of luck to you.

JFPinPa car is a 2000 Boxster s 3.2 motor .Motor was from RND engines installed 23k miles ago .Been driving it for 2 years do oil changes every 2500 miles. First time I have seem stuff in the filer.

What kind of warranty does RND have on their engines? 2 years and 23k miles seems odd to have this kind of wear considering your oil change regimen.

The 2000 VarioCam system is a pretty simple on/off setup. The exhaust cam position is fixed relative to the crank, and the intake cam position moves a fixed 24 degrees relative to the exhaust cam. The movement of the tensioner is reversed for the 4-6 head. At approx 1,500 rpm the cam solenoid/tensioner moves to advance the intake cam, and at 5,500 rpm it returns to the original position.

no real change as rpm increases

You have a bad VarioCam unit.

JFPinPA I could not upload the last two pics on was at 4000 rpm and 2600 and the numbers moved a about ten thousands of and inch they were still both -2.xx .Are you saying its bad because I found green rubber or the because of deviation numbers ? I am not questioning your skill .I have my old motor that has both vario cam units that I could steal .I know that there is a lot of green rubber in these Motors .All the Intake seals are green .The people who put my motor in had be buy two sets . if I pull a valve cover off will I see anything to tell me they are bad .I see the pic of the valve that is bad and the whole cycling assembly had to come all the way out .I am very confused as RND says there is no problems .Thank you for your help sir.

Are you saying that you are not seeing the actual cam angle change with RPM, or that the cam deviation values are not changing with RPM? You should see a massive change in the intake cam position with increasing RPM, but not necessarily any change in deviation.

I apologize for not knowing how to use the software .I think I see what I was doing wrong .I have to have the cam angle and deviation checked. This is what I got tonight.

At what RPM was that taken?

About 4200 rpm.

Then your VarioCam is still working. You cannot just pull of the cam covers, that requires holding fixtures to prevent fracturing the camshafts.

At this juncture, I would suggest taking the car to a pro and have them drop the sump cover and see how much green rubber materials they find.

Thank you JFPinPA I will keep an eye on it now that I have learned what I should be doing .I have read that the deactivation should be within plus or minus 6 degrees .Is that correct ? And at what RPM ? Still not really sure what spec Im looking for as far as whats good and whats bad.Thank you so much to all the Forum members and especially JFPinPA Thank you sir.

Cam deviation is a measure of how far off the cam position is from the ideal position. The actual cam angle should move from near zero to around 24 degrees if the VarioCam goes active with increasing RPM. Cam deviation limits are +/- 6 degrees.

And please stop calling me "sir"........

Sorry Mr.JFPinPA its all part of Management training from my last job.Well brain washing .To treat everyone with respect . I was supposed to make my guys fell like I was there co-worker and not the boss. We made crankshafts for the oil industry started out as a 4000 pound billet of 4140.Now I'm back at Goodman as a tool and die maker. Been a die maker for 34 years now.Thanks buddy.

Hmmmm so the 3K rpm and above driving threshold has no vario cam wear benefits? (for 2000 3.2 S engines )
