Renault Clio 1.5 DCI Y reg serious knock in engine took of sump crank shaft broken all so No2 main bearing cap

Question

has any one experienced this problem why has this happened any information

Answer 1

i wont be much help just to let you know i was a mechanic in a renault dealership up until last year and we never had that problem with them..alternator pulley used to disintegrate jaming the belt but they used always snap the keyway on the camshaft pulley and end up bending valves etc again never had one with a broken crank...must agree with the guy above get a second hand engine even putting a crank in it if it stopped while driving then id put money on alot of other damage

Answer 2

Hi

Is this the same engine which had a broken lobe?

This engine has either been constantly and seriously over revved, or it is just one of those things, and I will wager that you need a new engine. As I said before, it is a good idea to fit a new timing belt and tensioner kit to a second hand engine before fitting it.

Cheers

Answer 3

for this type of damage suspect a combination of severe abuse and neglect [oil starvation] when you get back from the salvage yard and before you spend any money on the "new" engine pull the cam cover if it is a sludge pit take it back. if it is a keeper in addition to timing belt and related parts a new set of crankshaft front and rear seals as well as camshaft seal[s] and probabley the water pump should be replaced [it will never be easier than when out of the car]
