I'd say you need to see live data for the turbo. Something like boost commanded and actual boost pressure. Actual should be at least the same as commanded. Also could look at fuel pressure, post values for a check. Cheap elm237 dongle and phone should read ok.

The contact area changed maybe, if the tyre is more like a bicycle tyre and pointed in the middle. We need scientific clarification on this! As the pilgrim says higher psi and tyre wears in the centre, or is that just because it is the weakest point across the tyre and takes more of the weight...

If the tyre doesn't stretch then it's circumference won't alter, like a tank track.

Had back window down last night and no fumes. Was down for 10 miles at 50 and 30. I fitted the muddy mods exhaust with cat. I found it a bit awquard to see which bend went where over the rear drive shaft at first but went on well. Not too noisy when driving, unless under a tunnel with the...

I fitted stainless exhaust, retained the cat, and get fumes when back window open. Wasn't too bad last time but it's been too cold to drop the back window. I shall brave the cold tonite and see if it still smells.

Possible rear diff mount, there's 3 and the front one fails normally. Being under load means the extra force has to go somewhere.

Is it exhaust fumes or the oil burning off the manifold?

Its a nearly 18 year old vehicle, with other fuses blown that you've just bought.....Needs to be diagnosed properly as they are complex beasts and just removing switches etc can introduce more problems. That means following useful direction from here or using a competent mechanic familiar with...

Have you lost the earth connection anywhere?

The bolt in pic 4 a few or the other bolts are bolted to the cam cover on posts that have a tendancy to break and spew oil out. I've now left them out of mine after it broke and I glued the cam cover back together. I believe if the wrong bolt is used it can puncture the cam cover causing oil leak.

I thought it was the colour of the light being important, no blue tint. I have been told they hold white paper to them to check the colour.

Swap to the other side, led lights often fail and start flashing.

There are 2 types of rear pistons. I think I still have a pair of the earlier ones which are no use to me. Difference is where the bleed nipple is.

I used one from a nissan qashqai, 20 pounds from ebay and slides back and forth. Fitted in place of the existing top section with one hole lined up to the original fixing and another drilled in the hinge.

If it sounds like air pressure escaping, it probably is. Check all pressure hoses as a small split can open under pressure. Doesn't need a big split, just like when we whistle.

I didn't change the filter when I first had the fl, and when it blocked caused pressure and oil leak. I now change it every year or so, and it's always dirty. That proves to me that it is stopping some gunk reentering the engine. So even with the mod it would neep periodic cleaning to remain...

I would say never believe fully what you've been told. How anyone can diagnose an issue without testing is just a miracle or educated guess. I would locate the control box and check it's input and output. The regulator only has 2 wires and the polarity is reversed to go up or down. Does the...

There's argument to keep the sponge filter, as it does filter any crud out. Easy enough to change every couple of oil changes.

I've always found it best to push down on the bonnet so there is no pressure load on the release mechanism rather than lever it upwards.

It would undo the filter housing bur possibly damage it. Get the socket as you'll need it every oil change.
