dropped back in to volvo again this morning to order the gasket. The guy on the parts desk did a bit of searching on the computer and found that up to a certain chassis number the gasket is called a heat shield and costs about 32 quid. after that its called a gasket and costs much less. funny thing...

Okay I believe you now, the discs will not come off without removing the caliper bracket. Going to try the breaker bar method, and to hammer on some 16mm 12sided sockets to the bolts. I am in fear of rounding off these bolts, anyone succesfully done it with 12 sided sockets --i really hate them you...

Use a wood chisel and carefully chisel the nylon off... I reckon.... Less likely to melt anything you don't want melted if you don't melt anything at all..... I agree, but it would need to be a small chisel... Very small. Also I fear for the ball part on the end, if you wack it with the chisel it w...

does anyone have any part numbers for the gasket? i went to volvo and its about £32! even the guy on the parts desk thought that was a bit steep. and i tried a couple of motor factors who told me that its dealer only. there must be a cheaper alternative! not looking forward to doing this! looks ...

AhHA! Welcome back Richard - glad to see the car's running! Still a few things to do to perfect it then? I'm here for a bit, at least.

I could melt it out!? pol Sounds like a good plan. Heat up the part with the ball while pulling, it will melt through the nylon and pop out. You could then remove the remaining nylon with a drill. I think it was on a dead gearbox I tried, and the nylon broke before the gearbox, but I like the melti...

I'm not sure that would be a good idea. As that is the super thin economy oil for modern engines. I think that it would possibly escape through every seal going. No way to tell without trying it of course. I used some water thin runing in oil in my rebuilt 480 engine, and I think it was 5W30 mineral...

Only the problem was simply ... the gauge was faulty! Try that too! :D
Ok I'll give you that one...

That's the only one I have seen to go wrong, and I have subjected boost gauges to some serious abuse (like 28 psi or so).

They are the same, only the hubs are different for ABS cars (the teeth for the ABS sensors).

You need to stick to the same sort, as the vented ones have different calipers. Other than that I think they are all the same.

I have removed that one. It's tricky as it is two parts that split to alow the ball to be put in before fitting. There is a lip where the circlip goes, that means the bush has to be tightly squeezed together to fit. Trying to do that to get it out is near impossible. I'm not sure what to suggest, ot...

Vaccum leaks can happen anywhere. Any pipe between the MAF and the throttle body being split or broken will make the car run lean, giving a poor vaccum reading. The intercooler tends to leak at the bottom where water sits in the crimped part near the end tank. There are more of those cloth pipe join...

or you fit a larger turbo which will be less restrictive and will produce lower charge temps, thus reducing combustion chamber temps along with lower exhaust temps. basically your turbo is too small and your tryin to get too much from it. try lookin at compressor maps, they may shed some light on t...

I'd wager if you compared the work done on the air by the turbocharger, to the increased chemical energy from the extra fuel, the later would be dominant. Corrections could also be made with the degree of intercooling of course! Its certainly important to keep an eye on charge temperature, and to r...

See what you have missed there is the timing. 5 years down the line these will start fetching money again. I'm not sure about that. In 5 years all but about 10 480s will have rusted away to nothing. Plus in 5 years it's unlikely that the parts to keep them going will be available. There aren't enou...

you tryin to over engineer your setup lol. ceramic coating is a solution for not bein able to set-up the car correctly. Ceramic coating is required unless you want to modify the piston cooling setup, but only if you plan to use more than 27 psi of boost. The reason being that the combustion chamber...

The signal is from the ECU, if it goes missing, then the car won't work at all as the fuel ECU uses the same signal to time the injection pulse. It's a loose connection on the instrument cluster itself. Either a poor solder joint or the connector pins that go from the main PCB to the intruments them...

You should be able to get the part from any Bosch tuning / diagnostic center, or bosch parts distributor.
