2002-2006 Cayenne S 4.5L V8 955 Timing Chain DIY (Part 1) Teardown 

Is that a Compliment? I will assume it was. Thanks! You should see part 2! If i was a tech of any type i would NOT be doing work like this. I make more $ and have a much more enjoyable job doing what i do vs being a shill for scamon tools and a slave auto shop of any type... btw i have worked in a few shops... NO THANKS. I rather enjoy making 2x the income doing high end tile and bathrooms.

You need to try a few things. Drain the coolant, pull spark plugs and pressurize each cylinder after rotating the crank so both intake and exhaust valves are closed. You need to go as high as you can on the air compressor 145 PSI. listen for air out of the coolant tank each time. If you hear air, the head gasket is SHOT or you have a cracked block sleeve. either way that would be a total engine tear down or replacement. Chances are you have an issue with the coolant system. you can pressure test it or vacuum test it. The 955 has MANY issues with the OEM stock coolant system and now the tank at this age and miles will explode. Replace it if its leaking or past 100K miles.

Did you figure it out?

used an oscilloscope on the CPS on both banks to confirm that they are working correctly and to confirm that the +8 on bank 1 and the +14 on bank 2 deviation on the timing was accurate. now that its done, bank 1 is 0 and bank 2 is +2.

As long as the cams are locked out (they only lock out 1 way because the slots are offset) and the crank is locked out, install the chains with the sprockets able to spin freely, then tension them and torque the cam sprockets down. That it. Make SURE you check the TDC of each piston. TDC on these engines does NOT give enough clearance for valves to open, if you take the sprockets off while the cams are pushing on lifters, then the cams could rotate VIOLENTLY and FORCE valves into the pistons. SO my advice is do what I did in part 2 describing how I fixed the 180* out issue I had. I was able to rotate the cams freely after turning the crank about 1/4 turn? Just don’t let the cams go without some thought. I’m not sure on the specs but that how I did it no issue. IMO lock out the cams properly in the back, then take off the cam caps SLOWLY, just back out each bolt a turn then move to the next, start from the inside center and work crisscross outwards. I would keep the crank locked out and the chains on to prevent them from spinning during this. It does not matter what you do after that. As long as it locks out its fine to reassemble. KEEP THINGS CLEAN, use coffee filters and mineral spirits to clean things before assembly. If you get any grit (too small to see) on the cam journals you are going to cause damage.

get ALLDATA DIY

So there is no mark to line up with the chain n the sprockets?

I have all data and Mitchell diy

So it doesn’t matter if the sprockets aren’t in their original position on the camshafts?

The cam shafts can only be locked out in one way for TDC. as for TDC of the crank, #1 piston must be at the top of its stroke and there is a lock out for the cranks harmonic ballancer. Sorry for the delay, im working on part 2 now. Im working on it as we speak now. Life got really complicated and busy but now ill get going on it. Thanks for the patients.

@@timsgarage1356 thanks my friend, loved the intro, thats as far as I have come for now

Sitting in unedited files on my NAS. Eventually I'll have it done. Life got very complicated and every time I get a chance to get this going something else takes priority. We moved to colorado, had a food disaster, starting school, work and a buisness to manage and let alone a workshop to get going and then another septic flood and another move just last month, to name a few setbacks.

not sure if i answered this but YES 100% the chain stretched. i was not that far off for it to still run but still give a code, see video for bank # differences, but the new vs old chain was an entire link longer only after 100k

im working on it!

@@uchia4206 in good shape there worth about 6k of they run. $12k if these services are done to them. The ones for your price have serious issues. One issue is a wiring harness issue or a neglect issue. Stay away from them. Always have any car you are looking to buy like this inspected by a Porsche tech. The owners we got his one from I did a lot of the service for so I knew this car well. And it was cared for.

you bet your cheeks it is. Why? did you have the forbidden kiss?

Lol, no but I'm not sure if I should replace to chain just in case ​@@timsgarage1356

@@STATSk8boardingbottom line, you DO need to replace the chain. You need to look at bank 1 and 2 and the deviation in your durametric scanning tool. If you do NOT have that, get it. at the 100K miles the timing chain is spent. you can do a little bit to buy some time but imo its not worth it.

​@@timsgarage1356 Oh boy... What am I all looking for between the banks.

@@user-vt1vn7is6w You must use the durametric tool and a laptop or the $$$ durametric tool, either way, you need to fimilurise yourself with the software, Cam shaft deviation /timing deviation, Bank 1 and Bank 2. the difference between both of them should be no more than like 8... so bank 1 could be -4 and bank 2 be 4. Mine was -7/+14 and it ran OK ish. anything past 14 gets dangerously close to the valves hitting the pistons. I don't know for sure but something like 17 and bad things happen. If the deviation is within 8 like i said you can get away with just resetting the timing and replacing the tensioner but this is just going to give you about 20K miles before you HAVE TO DO THE SERVICE. the re timing is just so it can run safely before you get the work done. When i was done, it was 0 on both 1 and 2.

yes, maybe ill have time to put it together to upload it soon. trying to move ATM. will keep the channel updated.

@@timsgarage1356 Totally understandable, been crazy to see someone actually doing this job and breaking it down. because i need to check out my timing. P0018 code on mine remains after sensors being replaced.

@@HappyFish50 have you checked the difference on bank 1 and 2 for deviation of cam location?

@@timsgarage1356 I have not... Its been a bit chilly and wet in the good old PNW. It is my plan to do so once the sun hits. the last time Driver side cover was off, Was when i purchased the suv and noticed it ran very rough. Stuck the good old waka waka 5000 on it and it ready misfires and bad cam/cranksensors. Replaced, plugs/coils/sensors/oil. after a week of driving, P0018 came back. once again im on the damn runner. its my DD... lol...
