URGENT oil pressure stop engine

<< < (41/170) > >>

rich83:
Why would the tensioner result in oil pressure loss? The oil pump is driven separately.

Pesky jones:
Is there a seal around the shaft that coul blow and thus spurt oil out? Or perhaps the plastic guides have snapped, letting the shaft shoot up further then it should and therefore let oil out?

rich83:
Pass. As above its gonna be a head off job i think, so you can assess any valve/ piston top damage.  :sad1:

Pesky jones:


This video shows what I think is a blown seal, with no control on oil pressure. This would bring up the message on my dash saying oil pressuRe turn off engine. As a result of no pressure, it isn't tensioning the chain leaving it to skip.



 This picture shows the plastic snapping, again I think would result in the oil pressure reading on my dash, and then subsequently the chain not being tensioned correctly leaving it so skip.

Both of these scenarios result in low oil pressure, and then the engine cutting out due to timing. It also supports the fact that the exhaust cam that is controlled by cambelt being correctly timed, but the inlet cam controlled by the cam chain being out of correct timing.

I agree rich, head off and proper inspection by a garage. I'm going to remove the cam chain cover this week regardless, just to see if what I think has happened actually has :(

rich83:
But the tensioner has a spring in it too. TBH im not 100% sure of the exact workings of the tensioner.
