Help Engine Knock

[sexysavage]

hi guys

was drivin my r34 gtt auto yesterday for the first time after a full service. was cruisin down the freeway and heard a knocking noise. pulled over after about 500meters and realised the oil was realy low and thin. i had only driving the car for about 30mins and had stopped for about 15 mins in between aswell so wasnt a great deal of time. wasnt thrashin it to much either and when came in i was just coasting.

walked to the closest servo and got a bottle of oil hopin this might help it. put in about a litre and a half and it came up slightly overfull. got rid of the knockin when it was idling. racv came out and told it was big engine knock or somthing along those lines and said im going to need an engine replacement.

just a few questions.

1. is this the only option for me? or can i get a rebuid or something of the like. also how much would these cost and anywhere you could recommend?

2. would the oil being very low be the reason or is there somthing else that could have been the problem? and if it is just the oild do i hav a leg to stand on in asking the mechaic to fix it?

3. if im goin to replace the engine wat would b the price difference in doing a 3litre conversion and maybe a manual conversion?

thanks guys

why was the oil low? do you have a leak or did did the mechanic who did the service stuff up?

low oil + freeway driving is going to pretty much kill the bottom end, sounds like a bearing or two is gone.

Speak to the people who work on your car

if your oil gets low then theres not much lubrication for the engine parts, big end bearings wear out in no time at all if they go dry, freeway driving will do this, yet a l and a half and its over full doesnt sound like its riduclously low, yet if u thrashed it alot like that, just thrashing in general can wear them out, you will need to goto a mechanic, you should be able to get a rebuild, u can get the bearing changed and crank linished if its just the bearing.
