URGENT oil pressure stop engine

[dazza]

Im trying to get to the chain and tensioner now but struggling with the last bolt on the chain cover. Even if I get it out f*ck knows how ill get it back in

Have you removed the battery and battery tray?

[Pesky jones]

Yeah removed that. Ive got all types of extensions but the socket that holds the t30 bit wont fit in the gap..think I need a t30 screwdrive tbh

[doylebros]

This long reach bit 1/4 drive so you can torque it up is the job.

[vRSAlex]

Deffo not looking good. 

[Pesky jones]

I will get the long reach bit during the week.

The only thing im hoping for now is that the tensioner is obviously completely broken, explaining the lack of oil pressure. Its obviously lost pressure causing the chain to skip, but whether that loss of pressure is due to a failed tensioner or a problem with oil pressure else where, such as oil pump.

However even if the tensioner is the reason for the lost pressure, I still wont know the extent of the damage.

In your opinion @vRSAlex whats the best possible scenario from what youve seen and read? I assume worst case is the damage is so severe it isnt worth repairing and new engine.

Il have to take it to a garage to get their opinion at some point when.I can afford every outcome, but are they even going to look in to the possibility of repair from what I can.show/ tell them or just jump straight ro new engine...

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. 

[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.

[Pesky jones]

I think the spring is just there to tension it when the car turns on, and then the oil pressure takes over. Also, if the plastic guides snap then it could still extend further then ir should and loose oil pressure.

Im no expert on the tensioner let alone the engine by any means. I mean really, im just stating my opinion and waiting for someone more knowledgeable to come along, read what ive said and tell me im wrong.

What do people think about these, im worried they will still be too chunky

These seem skinnier but only 100mm long. I think this will be long enough. Think this set also contains t27 and t30. The guide ive been following says they are t27 bolts but ive been.using a t30 so far and it fits fine?

[dazza]

get something like this with a 1/4 inch ratchet adaptor.

Here is mine with some wobble extensions etc.

[Pesky jones]

Ive already got something like that daz, problem being the socket for the bit is too thick too fit through.

My 1/4 racteht set is good its got loads of entensions etc but it all uses the socket thats too thick

[Pesky jones]

My dad showed marius the photo of the camshafts and he said that some turbo engines have the valves set further back so might not have done any damage, seems unlikely to me seeing as some have said I could have valves bent but thought id double check with you guys anyway. If it was the case then im thinking replace tensioner and chain, realign the timing and then do a compression test.

What do you guys think.
