Three months ago I had the engine out after a rattle developed and had new IMS bearing, crankshaft bearings, chain tensioners, water pump and air/oil seperator and for the last 3,000 miles everything has been fine. Had the oil changed 1,000 miles after the engine work was done as recomended so I am now mystified what could be cuasing a new rattle.

No "check engine light", no drop in oil pressure, no loss of performance just a rattle from the left-hand side of the engine.

What is over that side to check out?

ETA... ominously when i lifted the lid it actually sounds like exactly the same noise in the same place as before on the right-hand side of the engne compartment and very internal!

Sure its the in the morto and not the catalytic converter?? Common that the baffles in the CC ca nbreak loose and create some strange noises. easy enough to hit CC with a ru[bber lallet and see what might be lose in there. Demosan
