I'm going to check my big end and main bearings tomorrow just to be on the safe side after a blocked oil pickup pipe. Does anyone know what size E-torx bit is needed to remove the big end bearings and main bearings on the Octavia VRS Mk1?

Ive bought a set of 3/8 Torx female bits from Machine mart, not too bad £11 or so for 5 pieces. E10, E11, E12, E14, E16. From memory E14 looks like the size for the big end bolts. Will clarify this tomorrow after I have taken the sump off again.

Ok next question. What is the correct torque setting for big end and main bearing bolts on the VRS Mk1 engine?

Sam

I'm pretty certain it's a 12 sided socket for the big ends, I think they are 11mm from memory, and the main bearings use a 19mm normal socket.

Why would you want to if car running ok.....Unless you really know what you are looking for and doing

If you have replaced Pick up pipe and flushed with new oil you were probably lucky. Don't tempt fate and cause another issue buddy.......

I just wanted to check one of the shells to see what the condition is. If they are fine then thats ok but if they are seriously worn and scored then whats the point in running the car? Someone on here suggested I should check the big end shells anyway after an oil starvation because the crank takes most of the damage? I would rather replace the shells if necessary(i understand if they wear to copper coating they need replacing) I dont want to drive it and blow the engine up. I'm just very concerned thats all. Unless there is a certain way of knowing that the shells are going to be ok other than dropping a cap off the crank then I see no other alternative?

The thing that brought this concern to me was my mother and fiancee said the car made a low growl sound when I put my foot down. She reckons its never sounded like this before. I looked up online low growl sounds and its possibly indication of worn bearings? I personally always thought worn crank bearings were hammering sound from the block? The engine sounds normal when idling and you can`t hear anything from inside the car that is of alarm.

Is it also true that if you remove a crank cap that you have to replace the bolts with new bolts as they stretch like head bolts??

No its the top end that rattles and gets the damage from oil starvation first

Sent from my Galaxy S3, not a Crapple!

Yes and I took the cam cover off and checked the cams and lifters. A very very minor surface wear on the cams, no grooves or cracks, in fact there was still a thin film of oil over the cams. I take it this is a reliable indication that the cam bearings are no worse off??

buddy I have replied to your earliest post,

Does your mother and fiancee know about the car and the engine? perhaps they know more than you lol.

on a serious note, i say again do not get paranoid,

Gain some knowledge of your car by reading what is on in Briskoda, and taking good advise from folks that know their stuff, then take appropriate action.

The VRS makes a number of noises like a turbo whistle for example and number of folks new to these cars can think turbo on way out etc. other noise as injector rattle and charcoal canister tapping that again some folks think major head wear etc

Replace the oil in a month from your last change/pick up pipe replacement to ensure a good clean out and refill with quality oil then do regular oil changes say every 5000 miles to be safe( i do mine every 4000)

This is the car that was run for 10 minutes with no oil pressure? Take a vid of the noise it makes when you rev it and post it, bottom end damage has a distinctive sound
