Damn
#1
Well I managed to snap the oil chain on the 6 the other day taking the sprocket, pump and big ends with it too :-(. Was updated chain too so will revert to genuine Peugeot now to see how that turns out. Was using royal purple oil 20/50 possibly to thick putting stress on the chain/pump? Will put silkoline 10/40 to see how that turns out. Half the price too fingers crossed :-)

Tell me about it bud :-( was having a bit of fun with a c63 that was so loud I could barely here my oil chain snap! But I'm very lucky that £300 is putting this right Rolleyes

If you want to put some miles on her bud, I'll put the kettle on, that will be about a 150 round trip with a coffee/tea what ever you drink in the middle ha ha Smile

Why were you running 20w50?

Bloody hell! 20w50!!

Unless you're racing and it's well over 120*C all the time, no need for anything like that... Mind I'm still surprised that's what caused the chain to snap, have you checked over the oil pump and confirmed the pressure? Sounds like maybe thr regulator is jammed and due to the oil being quite thick, the pressure would have been very high...

Re-examining the pic, I think the sprocket failing is the cause of the chain snap. The thickness of the oil pushing the pressure too high, and putting too high a strain on the sprocket,

i think reducing the viscosity of the oil will prevent this happening again Tongue even though the car is not mine, it was gutting to hear she was broked... But happy days are here again Smile I bet you can not wait for the weekend bud ha ha ha

20/50 was what rich w advised and as he built the engine didn't have any reason to doubt it. He has used it many times before an never had this problem. It's all fixed now so hope it's all plain sailing again bwap bwappppppp

Have you got an oil pressure guage installed? Such a vital instrument with a highly modified engine like yours!!

I used to love seeing my clio have 6-7bar oil pressure on a cold start up Big Grin

No I haven't mate but I guess I do need to so I will get onto it. Any particular one or are they all the same pretty much? Thanks thou sound advice

The oil viscosity has nothing to do with it myself n a few others use rp with no problems. Its likely just to be a componant failure

seeing oil pressure at 6.5 bar above 4Krpm with oil temp greater than 100c is what i like to see Wink

Oil pressure is purely a measure of restriction anyway, if the oil is like tar, it doesn't mean it's lubricating the bearings...

You could have the pressure up against the regulator at 6bar with porridge in the sump... It wouldn't be doing anything as it'd barely be able to get into the bearings!

Unless you're having serious oil pressure drops at high temperature, I'd use the closest to the standard viscosity as possible.

Bearings all done and back together , engine flush , new 10/40 oil in and new pug oil pump and chain. Took her out for a 20 mile run and all seems well so watch this space

Rp 20/50 is recommended for supercharged, turbo and nitrous engines btw

I am using the std dash temp gauge,
I have installed an aftermarket pressure gauge and a second oil light that just illuminates on very hot oil at tickover think its set for 15-18 Psi where as the std light is 5psi
so its an advance warning light of low pressure
