It all kind of points to a compression problem if I was being asked. Although I'm not telling you for definate.

Like northener says compression test first. Let us know what happens.

Well my bad news got worse last nite as on my route home from my flat a mini bus scrapped my bumper bit gutted man as its stripped the paint and creased my lovely rust free!! drivers wing. The guys claiming it was my fault but it wasnt my car was staionary so in theroy he scrapped his mini bus on my car. ill post pics up wen ive got bit more time.

The car is now wat feels and sounds (whilst driving) like its cutting out at low revs so as i push the accelarator the car just become unresponsive as if the theres no combustion. ive checked all the spark plugs they seem fine usual tan/grey colour, the leads all seem normal. the car cutting out could it be due to under fueling?

ill get my dad to help me with the compression test and see if the rings are worn. Is it common for piston rings and vavle stem oil seals to go with a car with a resonably low mileage?

how would i check the turbo seals?

And while i remember Scoupe i get around 240 odd to a brimmed tank without caining it (because i cant coz its pinking)

Thanks for the help guys i hope i get this fixed as my silvias my daily driver I need it for work etc thanks again

Thumbs up

well had a look this morning and this is my findings had a look at the cutting out whilst driving and figured that the fuel pump was being starved on low fuel (just above the red) as the wee catch tank thatfeeds the pump wasnt filling as quick as it should due to all the mucky deposits. so my dad and myself pumped all the fuel out and got all the shit stuff out and cleaned up the inside of the tank and put the fuel back in. seems to be running sweet now no more cutting out etc. (ive got pic to post up later this evening if not sunday).

We also had a look at the smoke bout five mins idleing. So we cleaned up some of the sensor connections etc and hooked up compression tester heres the results
Cylinder Dry Oiled
1 110 125
2 100 120
3 100 130
4 100 120

The dry run was taken with a battery without full power the oiled ones were taken with a battery charge whilst taking a jump from my dads triumph herald. He says that should be a average result. Hes got a colortune interesting bit of kit its older than me! basically u put it in the 1st cylinder spark plug hole and connect the ht lead onto the top of it and it lights up blue if its running rich and orange if its running nicely. We put it in and started the car and sure enough it started and was running blue which means the cold start is working as after a couple of mins once it had heated up it turned orange mens is not over fueling which can only really leave the turbo seals or the valve stem oil seals.

So thats my intersting morning. i wouldnt no were to start with the turbo seals is it a easy job?

Thanks for everybodys help its really appreciated. Ill get the pics up of the fuel and all the particals we took out the tank couldnt belive how much of it there was lol.

Heres my pictures from yesterday.

What petrol should look like.


Heres what was in the bottom of my bucket after pumping the petrol out.


We put the bottom contents of the bucket into empty bottles of errr whiskey lol.


Heres the empty bottles lined up in compaison with how far off the bottom of the bucket the fuel was u can see the colour diffrence. we left them for bout 10 mins until all the s*** had settled to the bottom.


Heres what was left in the bottom of just the bucket after the fuel had been removed.


Finally after pumping some fuel back in my nice clean partical free catch tank.


So have you checked to see wats lurking in your petrol tank!?? Sorry its a bit picture heavy tried to keep them small.
