Thread: Disturbing find in waste oil pan(ic)!

The Peugeot 505 SRDT is 1985 and Id be surprised if the chain in that was as lightweight as what I found, so I suspect the LR oil drive chain.

BUT - if they do not run a split link chain, how could the link end up in the sump without a catastrophic failure? Maybe said failure did happen, in the past - but does not give me much confidence in whoever did repairs. Personally, I'd clean out the motor of any chunks of loose parts before reassembly..

No, nobody else has ever used my catch pans!!! (I'd be shamed to let them, they're not pretty..)

Cheers, I appreciate the replies

Oh crap ..... BACK UP ..... You said SM ?? Maserati V6's are known for timing chain issues. I've never worked on one, but I don't think the primary chain even has a tensioner. Could it have been from this? If there is even the slightest chance this link is from the SM ...... DON'T EVEN ROLL THE MOTOR OVER!!! I've just been looking at google. It looks like the primary and secondary chains on the masterati are duel chains. So it *is* possible for you to drop a link and it'll still run (as you still have the 2nd chain keeping everything lined up and spinning).






I gotta say, I'm really envious of the SM. I've only ever driven a very low milage museum piece that was automatic (which spoils the revvy/peaky maserati motor in it).

I asked one of the SM experts that posts over on aussiefrogs.. This is the chain size in the SM/DS

DS and SM both use ISO 06B-2 chain which basically 3/8 inch pitch, ¼ inch roller British Standard double row chain. When used in European cars, ISO 06B-2 chain is called 9.53mm pitch x. 6.35mm roller diameter. The roller width is 5.73mm per roller and the links have a 23.8 mm overall width).
