2001 Boxster S Engine Noise

Cool beans!

Thanks for the 'post of experience'. The engine is supported in 2 spots with a large piece of HDPE. Only need to hear it for a few seconds to determine what path to take.

So, Wilson01S, are you fixed then? What did your engine tell you when you ran it? No more "clunking" I hope?

I too heard that by removing the OLD oil from the chain tensioner and replacing it with NEW oil, it may calm down the 'regular' chain startup rattle…yours was NOT a rattle - but the RATTLESNAKE SHAKE!

Bet you'll be doing REGULARLY SCHEDULED oil changes from now on!

This car was my "Uncles" and I believe he followed the 15,000 mile oil change interval....unfortunately the car has 36,984mi and its 12 years old!!!!!!!!!

I have always changed the oil twice a year on our 98 boxster base (it only gets ~2000mi/year) so I do a change in the spring and a change in the fall before its stored.

Anyway I pulled the cam cover yesterday...I will take the cams out today. Nothing looks abnormal yet with the clutch, IMS, compression, spark plugs, exhaust manifolds, and now under the cam cover.

ByProDriver- is there a spec or anything I can look at to see if I would have a failed lifter? I will have them all out this afternoon and I am just wondering if there is anything I can look for to see if one is bad?

Thanks again guys and I will keep you posted and upload a ton of pics over the weekend!

Just like the tensioners. Cook at 270 degrees for about 8 hours in new oil, then pump up. Make sure to replace lifters on same valve if they pass the test. Is the tensioner in this pic the one you removed??

[Wilson01S]

That looks just like the tensioner I inspected. What tensioner do I need to remove in order to take the cam gear and chain off the drivers side head?

Also what is the "test" for the lifters? I will submerge them in hot oil, but is there anything I should look for, or is there a certain amount of pressure they should be able to hold?

The 4-6 cyl. chain tensioner is on the top side of the head. In the picture below it's next to the cam position sensor. It's under the A/C compressor.
Let the lifters "cook" for a good 8 hours at about 250 degrees. Press down on the plunger to purge the old oil, you will see dirty oil squirt out, keep pumping until no more dirty comes out & the plunger gets too hard to compress again. You might need to add a quart of Marvel Mystery oil to the pot.

Thanks again for your response. I found that tensioner and removed it, followed all the steps on the pelican parts tech article and got everything apart no problem. I let the lifters cook in oil about 220 deg for an hour and I could not plunge them at all...no pump action, no dirty oil. I will add marvel and cook longer?
