13 plate MK7 2.2 RWD

[Ozzy2]

Hi, all, just bought a 2.2 mk 7 transit RWD. Had a blown turbo, That's not a problem i thought so i fitted a new turbo and a second-hand intercooler and exhaust. Problem is engine starts lovely on the button even in the cold, no knocking or smoking. You can rev it up stationary without any issues or smoke, But if you drive off you can hear a (what i think is a diesel knock), Only knocks on low RPM below 1500 RPM, and stops as soon as the engine gets slightly warm within 1/4 of a mile then stops. you can leave the van all day and start it up and drive off without any knocking, just that initial start up in the morning. The van runs well apart from a power lag below 1500rpm wont pull very well. get up between 1500 to 2000 rpm and the engine pulls well. Unsure if its an injector fault, EGR valve or the turbo, Any help greatly appreciated

that sounds like oil draining back to the sump .. change the oil filter as the anti drain back rubber flap inside of the filter cartridge could be defective. but that would be a few seconds not minutes.

no way of knowing what the oil pressure is without a oil pressure gauge .. to check out if pump defective ..

thats if im even right about this

Hi, no oil light pressure on or flashing even when it happens, oil light comes on with all other lights when you turn on the ignition. But I'll defiantly change the filter as a matter of course, thanks

the oil light does not come on until below 5 psi
