      Keep it on topic, topic is about 3.6 timing, not turbos installs. Don’t derail the topic.

      Hi, first so sorry for my bad english.

      I ve purchase 3 month ago the car, when start cold exaust make noise like no mufflers for 1 minute about, then ive Heard noise like loose chain. Check block 208 with vcds and result -3 degree. My mechanic change valve cover gasket because a little oil leakings and we saw you can see in video link. My question is could the hidraulic tensioner bad. After run 15 minutes all noise dessapear.

      Videois in spanish)

      There is nothing out of the ordinary with the chain as it appears in the video.
      It’s tight, and those phasers will do what they do there.
      A recording of the noise would help more.

      I agree with Nater, my chain setup in the video is normal when assembling.

      Extra engine noise when cold starting a minute or two is normal but a video to better understand would helpful.

      Thanks to help me, yesterday with my friend and mechanic unscrew the chain tensioner, it shows wear points, brillant parts like
      as friction in cilinder and piston, because we crush it several times and it is disassembled showing the inner part of the cylinder.

      I hope you could understand my english...

      What is block 209 reading?

      I’ve heard the cams should NOT be 2* different

      Has anyone had a hpfp lock up and take out the timing chain?

      Info on 208/209 :

      Blocks 208 & 209 should be as close as possible to 0°, the spread should not exceed 3°. The absolute wear limit is 8° spread whether + or minus. If the spread is well above 3° but under the limit, then chain & guide replacement should be considered.

      Jack over at the Ross-Tech site says this about chains:

      "A quick review of locking the cams and seeing how far past 5MM of the TDC mark on the harmonic will indicate a stretch as per the RTFB."

      Sounds plausible, I haven’t heard of this happening but anything is possible.

      Good info, I’m going to check my Uber low mile 2017 Touareg 3.6 in my corrado

      Well here's my situation. I picked up an 07 touareg with broken upper timing chain, and some bent valves. 3.6 liter built in 06. Not long after tearing into it, it was easy to tell that somebody else had been there not long before me. Oil pump felt good, replaced intake variable valve cam gear, hp fuel pump cam gear, all guides both chains and adjusters. (Even though the chain set looked almost new and had recently been replaced). Cranked over by hand fine. Started and ran good, but lots of chain noise and an awful clack every 5 seconds or so... I started it ran it shut it down etc for about oh maybe 2 minutes off and on before whatever was causing the noise made the chain jump a tooth and threw the timing off. I haven't cranked it since because I really don't want to break the chain and bend some more valves. About ready to find a junkyard engine for that thing unless somebody can point me in the right direction. Thanks in advance. -Dave

      Get a low mile 3.6 from the junkyard. My buddy got a 2012 forged crank 3.6 for $900 with 29k miles. It’s not worth doing all the work to replace valves/timing parts with there being so many 3.6s in junkyards.

      In follow up to the timing variance. I checked both my 68k mile 2010 CC and my 2017 3.6 with about 20k miles in my corrado and I now don’t believe the need to pay attention to the block 208/209 guidance that has been talked about. It’s worth keeping an eye on block 208/209 but not gospel most replace info.

      Thanks for sharing that. I don’t think I’ve ever seen a primary source for the guidelines that people refer to regarding blocks 208 & 209, just lots of second hand repetition.

      It relates back to the 2.8 & 3.2 VRs. I don't think there has ever been any direct correlation to the 3.6L

      The primary source is a gospel type VW issued tech tip article in the very first post specifically directed at the 3.6 motor and cars and nothing else. I'm sure the numbers are supposed to be checked engine warm and accelerated past 3200 RPM 2-4 times in park or neutral from idle with all electrical consumers switched off before checking. I know it doesn't say that but it's what I would do after so many years working with VW to make sure I was getting the most accurate measurement possible. Maybe even a fresh oil change to add icing and know I have a good baseline. Additionally I would like to add the tech tip only directs a technician to these MVB's for excessive fuel pressure issues so if you do not have high fuel pressure faults in correlation with parameters listed in the Tech Tip it might suggest the high pressure fuel pump is not out of time therefore excessive wear has not occurred. The Tech Tip also only applies to cars prior the 2011 engine updates so it's possible that 2011 and newer engines have different tolerance values for these MVB's and this Tech Tip no longer applies to 2011 and later cars. Without more data there is no way of knowing how valuable MVB 208 and 209 are for measuring timing chain stretch but the Tech Tip does at least give us a guide for something we can explore more.
