  1. Set of 4 Samco Blue Silicone radiator hoses in never fitted, as new condition. 

     

    Turns out sometime ago I managed to buy the wrong set for my Z. Please note these will only fit MY 2007 onward. 

     

    I'm looking for £85 including postage.

    Payment to be made via PayPal (buyer pays transaction fees), bank transfer or cash on collection. 

     

    Collection can be organised between Swansea and Bristol, I make the journey at least 3 times a week.

  2. Most modern MAF's do operate on a "hot blade" principal and the air passing over the blade is converted into a volumetric factor and very an intake air temperature reading. What I am commonly seeing on the latest Euro 5 and Euro 6 diesel engines is that the readings of air flow seem to remain "accurate" for a more than reasonable amount of time ie. 3 years plus (this is on machinery running in excess of 2500 hrs a year, but I am regularly seeing huge discrepancies in intake air temperature readings, often 20 degrees out of calibration.

    During the Bosch training courses I attended for these engines we were explicitly told to never attempt to clean a MAF using brake cleaner or any other solvent based solution, these leave a coating on the blade once evaporated and as the blade heats up during operation it causes the blade to burn rendering its readings inaccurate. Another factor that can cause issues with them is water vapor in large quantities contacting the blade during normal operation. I've seen 3 instances of our machinery being pressure washed whilst the engine was running and water soaking the air filter causing it to tear and water passing over the MAF rendering it useless.

    These hot blade MAF's are not without their problems but they are far more accurate than previous types used.

    I'm starting to see more diesel engines now without MAF's and manufactures opting to use MAP (manifold absolute pressure) sensors and a separate intake air temp sensor in the induction trunking instead.

     

    The easiest way to check the calibration would be using a decent diagnostic system and checking the air temp readings against ambient air temp. Check the air flow rate usually displayed in Ltr / hr or Ltr / min and then calculating against the engine speed

  3. Thanks guys your dedicated reading it this time on a Saturday ������

     

    Had just got home from work, it's nice to see such a big change in a car. This type of work really impresses me, I could spend a day or two stripping and rebuilding an engine or gearbox and nobody would be able to tell the difference apart from the owner who knew there was something wrong but the results from this car are much more tangible and are there for everybody to see :thumbs:

  4. Thats damn good work, just curious ( newby and all ) how long will the swirls be gone for? Thinking about getting my paint corrected but for £200 idk if it's worth it, depending on how long it lasts

     

    It's paint correction not a temporary repair, the defects in the top coat are polished out ie. the surrounding material is polished down to the level of the defects not filling the scratches in to bring it up to the level of the surrounding material.

    If you were to just use a wax on a scratched surface the wax fills in the scratches and brings the level up to match the surrounding area, over time the wax will wear off and the appearance will return to what it was. As long as the painted surfaces are washed and treated correctly the correction will last as long as taking care of new paint will, hope this answered your question.
