    Default Engine fresh rebuild (Forged) - Car sounds like a Diesel/Tractor [Videos]

    Car is 80k mileage - 2008 model
    Jetex air cone filter
    Remus 3 piece exhaust
    Courtenay sport intercooler
    NO REMAP (Standard remap)

    Hi just done a engine rebuild with used RRS forged pistons and conrods from Regal autosport

    Had them checked over by 2 different mechanics, say they are in good condition

    Pistons - http://www.regalautosport.com/shop/R...iston_Set.html
    Conrods - http://www.regalautosport.com/shop/R...rsa_D_VXR.html

    (These pistons were known to hit the oil jets within the engine so I bend the oil jets to clear the pistons)

    Reason for rebuild, car suffered bottom end damaged - metal went round the entire engine

    - Got a different bottom end

    - Used original top end that was involved with metal damage but sent off to be reconditioned - skimmed head

    - All new shells

    - New water/oil pump, new oil cooler

    - Using Shell helix 5-30 oil

    - Compression tested all 4 cylinders - say 200

    Car sounds very noisey like a diesel/tractor

    Can anyone shed some light as to why it sound this noisey?

    Was told a forge build is noiser than standard pistons but this sounds a lot noiser than it should

    The noise that irritates me the most is when the car is revved/accelerated

    Anyone able to diagnose?

    Been told it's top-end camshaft noise

    Car drives fine... just noisey!

    Did feeler guage to check clearance seem ok except for one was bit tighter than others

    Well it was sent of to be fully re-con so I imagine they have fixed it rather than clean it

    I was wondering if they had the cams out then took lifters out and not put them back in correct order.

    Hmm no idea? The place that refurbished it seems to do any engine, no doubt mines the first Corsa VXR top end they've seen

    Might just visit a garage to see if they can do anything affordable, any ridiculous price or unsavable then just gonna split Caen or sell, taking a serious hit to my wallet and sounds like bag nails
