So my brera journey hasn't gotten off to the smoothest start. Went to start it this evening, after been driving it minutes earlier and it wouldn't start. Insufficient oil pressure popped up initially but didn't appear after. The hope is that it's a solenoid in the starter but it would typical of my luck that it ended up being far worse. In the end the starter sounded more like a drill with the whurring noise it was making - hopefully that isn't as a result of me trying to start it a few times.

It gets better from here doesn't it!? 馃様

Just wanted to provide a bit of an update on this in case someone has a similar issue in future. So it turns out the issue isn't the starter - the insufficient oil pressure warning was accurate. Had the car looked over earlier by a specialist and it appears that a bolt has broken on one of the gears that drives the timing belt. This has likely resulted in the rockers being damaged but I won't know for certain until it has been opened up. Apparently he has only seen this occur 4 or 5 times before in the last ten years.

There's also a slight chance that the timing belt might have jumped a tooth resulting in the compression issue but the belt itself was changed only 10k miles ago by a different specialist so it's unlikely. Hopefully it isn't because it will be major surgery and cost if it is.

So not the best of starts but hopefully it'll be up and running again soon and for longer than 3 weeks this time.

You could not break any rockers without the timing jumping at least a few teeth. Was the water pump changed with all the idlers and tensioner....not replacing them as a set is a sure way of getting issues like this.

Ya the pump was done as well. When he told me about the rockers I had a look on here and I've read a few posts of them breaking on people. I'm just hopeful at this stage that it's not going to be an engine rebuild. Won't rule anything out though

They will nearly always break when the cambelt jumps far enough or (more normally) when it snaps....its a design feature that they are sacrificed to save the valves/head. Does not normally need an engine rebuild as long as you can find all the needle bearings from the rockers. But if you have only jumped one tooth there should be no valve to piston contact...this is what breaks the rockers.

that gives me some hope so, thanks for the info. I'll post an update when I get it just for reference for anyone else.

When my cam belt tensioner went fubar (on a 6 month old cambelt kit) it broke some of the rockers... As said, they are designed to be sacrificed... I got a full set of rockers for about 拢80, new cam belt kit and some labour and job done

ok so a bit of an update. car has been opened up and the culprit looks to be a rubber spacer at the bottom of the cam shaft which, for whatever reason, decided to disintegrate and get into the timing belt. This of course would have thrown the timing out - by how much I'm not sure. The net result is that all the rockers are broken. Hopefully, as mentioned above, the rockers have taken the hit and protected everything else.

I'm wondering now what exactly was replaced when the timing belt was done 9k miles ago - as @alfaitalia mentioned earlier, not replacing the idlers and tensioners are a sure way for this kind of damage to occur - so the likelihood is that only the belt and water pump were replaced. Zero comeback on that I assume.

You say a rubber spacer had come off the camshaft and caused it so no need to suspect things weren鈥檛 changed as I assume they are all still intact? Either way it鈥檚 a new cambelt kit when you rebuild anyway.

Not sure what this rubber spacer is though I can鈥檛 recall having one of them on mine

the crackshaft pulley was the cause of the problem. the central rubber bit broke in one spot and the piece that came away fell onto the timing belt throwing everything out. hefty bill to sort everything out too. after three weeks of ownership, the car is costing me 鈧2 in maintenance per mile driven to date 馃槱.
