Blu_Ray_UK2007 Posted June 18, 2023 Share Posted June 18, 2023 (edited) Hi everyone.My car's engine started to knock about two months ago.The car engine is now being put back together.The road bearing for cylinder 3 is gone.The engine journal has marks on it.a lot of metal rods Took the engine apart.Block is scraped and drilled again.new oil pump, new oil cooler, new timing chain, new seals, etc.People told me to buy a used engine, but I didn't want to take the chance.These guys look like they're doing a good job. A few of them have worked for BMW in the past, so they know what they are doing. I'll let you know when the work is done.Thanks to everyone who replied to the last post.

Mistral Posted June 18, 2023 Share Posted June 18, 2023 Is there a possible explanation for the failure? Quote Link to comment Share on other sites More sharing options...
drummer Posted June 18, 2023 Share Posted June 18, 2023 I'd say neglect, based on the staining and baked-on 'parts'. Brown sludging like that does not occur on well-maintained diesels. Quote Link to comment Share on other sites More sharing options...

To my untrained eye, it seems to be too late. Quote Link to comment Share on other sites More sharing options...

Some folks utilise oversized shells and grind their own cranks. There used to be the option of metal spraying. Quote Link to comment Share on other sites More sharing options...
