Strange. Its possible I would guess. But it shouldn't cause an extreme pressure drop as BenzX is reporting.

A check value or something in the updated design must be different. I guess the new ratchet style relys less on oil pressure?

Dan,

What is your oil pressure at idle with the oil nice and hot? What's your mileage? What weight oil?

I have been running 20w-50w in mine. Didn't notice and change in pressure after my tensioner update. The lowest my gauge will go is over 2.5 bar at idle with the oil very hot. The odometer reads 155k.

On an side note, if you read the old post of mine (http://www.peachparts.com/shopforum/showthread.php?t=8723) when I replaced my tensioner, I had an exchange with Benzmac and MBDoc concerning some pieces the they claimed didn't belong within the tensioner cap. I put them in anyways with no ill effects.

BenzX,

I guess we will have to see what that mechanical gauge reads. Reading your father's earlier post about the chain slap, how far apart did you take it to replace the tensioner? New rails and chain guides?
