I’m not convinced having done all that and have the worst on off thump now.

Down to about 12-14 in the morning. Definitely not as cold as the desert in winter

Went to fit a pair of new extended roof rails on the new transport, and managed to break a s/s bolt in the rooftop captive nuts, while I was attempting to clean up the threads. Should have known better, and now waiting for our local mobile "Mr Stud Remover" to fit me into his busy schedule.

You can just buy the inserts.
Cheaper than you’ll get it fixed.

Whatever was leaking and dampening the shock load is fixed! I know when it's coming and modify my foot to control it now.

Just picked mine up from having a cracked driver's side intake manifold replaced @120k kms. Same experience as many others. Started with a light hiss for a couple of days, then a Restricted Performance fault.

Nanocom tells me code P006A. Telltale oily stain under engine cover on driver's side. Hardly drove it but nursed it when I did to keep it under 2,000rpm until I could book it in to be fixed. Thankfully Roving Mechanical were able to book it in pretty quickly (replacement manifolds kept in stock) and turn it around in a couple of days.

As per pics below

Are these manifolds made of plastic? to keep the weight down i guess but seems crazy to me for so many critical parts to be made of plastic not to mention the water connector in the engine bay (thankfully my prev owner replaced with an all aluminium type) guaranteed not to crack or split but still cannot understand why the manifolds would be suitable to be made from plastic. Wonder if anyone out there is manufacturing steel manifolds to do away with the plastic ones like they have done with the water connector thingy...

There is nothing wrong with plastic for the use case if it was properly designed in the first place. It wasn’t designed to cope with constant flexing which has been rectified in subsequent designs.

Yup. What he ^^^ said.

Modern plastics are very fit for purpose once they model it right. Even FIE gets it wrong sometimes, and doesn’t always show up in RWT until beyond certain work cycles.

Yes,they have been using plastics for those parts on engines for many,many years.
