Hi all, just wanted some advice my 2.0 cdti (160hp) insignia recently decided to give up the go due to the dreaded no oil pressure warning sign resulting in complete seizure of engine. To cut a long story short I recently purchased a recon engine for this from an engine specialists up north, however after the engine arriving to my mechanic we noticed that the engine they sent was the block of an old vectra 1.9cdti, which has now been modified with all the parts and insides to bring the spec up to a 2.0 litre cdti engine which is same as the one that’s in my car currently. There are a couple of modifications which are different to my old engine which had us worried but we have been told these are normal and is part of the fix to stop the original issue happening again. Has anyone here ever heard of this or know of it engineering company’s doing this. My New engine is covered under warranty and apparently there are 100 s of these been sold Without issue.
