Peugeot 308 1.6l THP engine problem

[Ceenine]

A friend’s vehicle failed to proceed at an intersection. The problem was found to be a wrecked tensioner. Fortunately and incredibly valves ere not damaged or any other major part for that matter.

The main supplier for replacements for the tensioner kit seems to be SWAG. Is it likely that any of the not upgraded kits are still in the replacement market or would they have worked their way through the system. I suggest that the obviously poorly designed tensioner should have been a recall item. I understand this would have been an expensive exercise for PSA.

That's not really something we can answer to be honest - PSA don't provide a date when a part is superseded - only on occasions where a part may have been replaced when a model is given a facelift and it is a differently designed part - so for example would only be applicable for a model from a particular build date that reflects the facelifted variant.

I can't speak for aftermarket parts suppliers of course.

Assuming you are referring to the timing tensioner - if you want the correct PSA part number for your friends 308, then just provide the VIN, as there are 3 variants of the 308 and multiple engines.

The vin is VF3**************[VIN obfuscated, can be read by forum staff]

VF3**************[VIN obfuscated, can be read by forum staff]

This is the timing tensioner for that VIN (you missed out an L and 3 from the VIN)

Part: 1675941180 is the replacement and costs £47 UK inc. VAT.

Sorry about the vin. The extra bits must have fallen off over the equator. I always thought there must have been some surplus digits/alphas to requirement.

I hope the replacement tensioner is made of stronger stuff and the retaining bolt, likewise. Every function has a weak link and it’s not the chain (pun) here. I won’t mention what the quoted genuine cost of the kit here in hot land. I don’t think it would fit in the forum.
Thanks for your help as always.

Have you tried after-market BMW parts suppliers? Here in kiwiland, engine parts are often (but not always) cheaper ordered using the BMW part number.

When I needed an engine top cover for mine, I ordered one from a local generic parts supplier who got it in from an (un-named) Australian supplier. It cam in a Moog branded box, but the part inside appeared to be genuine PSA with the PSA logos ground off with a dremel. It was half the PSA price.

Thanks, I will give it a try. I am interested to see if the tensioner has been improved over the original. I really can’t imagine where the forces originated to snap it off it’s base. I couldn’t find any reference to the problem part on this fantastic forum. It clearly wouldn’t be the first time it has failed.

For reference purposes, what is the engine code on this vehicle please?

[gwest]

Don, the engine code would be digits 6-8 on the VIN- in the case of my 2013 DS5 THP155 it is 5FV. I have bought cam chain tensioners from EAI in Melbourne for about $90 and for $16 from China. I could not discern any obvious differences and they both had the holes in the top indicative of revised versions. Both crunched when you compressed them, which I found disturbing as I would have expected the action to be smooth, as it was on some that I have removed from vehicles. They worked ok however.
I am astonished that the failure your friend experienced was caused by the tensioner body breaking- after all the tensioner is merely pressing against the rear of the plastic chain guide. It will be interesting to see how the valve timing looks - it would be a bonus if you did not have to undo the torque to yield bolts on the crankshaft/camshafts. Especially the crankshaft as making sure there is no oil on the faces of the two chain sprockets (timing chain and oil pump behind it) and the end of the crankshaft is demanding.
