Wow. Scary.
I keep a fire extinguisher in all my vehicles and recommend it to everyone!

 

Gotcha...
I don't know what to expect with new plugs...
how long before they look like the one in the pic.
Also I wonder what the flush does...
Wish i had mechanical knowledge.
I'll keep you posted.
also... how is it not smoking by now (knock on wood) or over heating.
This my 3rd Rover I learn more with each one...
I had an 03 before this one... my favorite was my 01.

Thanks pal

 

Putting new plugs in, or at least cleaning the present ones so they don't have a big blob of goo on them, means you are eliminating a potential reason for the truck to act weird.

It's best when trying to diagnose something to do one thing at a time. That way, when something gets better you have a good chance of working out what the problem was.

If you change the plugs and all the misfires go away you know it was caused by the plugs (ultimately). Of course, what's causing the plugs to foul up is the next question. If you change all the plugs but still have one misfire, check the wires etc.

If you change everything, you don't know what the problem was.

Edit, you have a stack of mechanical knowledge, you just don't realise it

When your mechanic puts new plugs in, get the tools to take them out again, and keep an eye on them. Take a couple out once a week or so. Maybe take a photo and after a few weeks see what's going on.

 

Thanks gov...
great advice
keep you posted.
what weight oil would you use?

 

Try and get more specific info about what snake oil the mechanic wants to put in.

I'm no expert on oil weights, so dunno. Others may have an opinion tho.

 

That spark plug is amazing.

I use Rotella 15 40 (non synthetic) in mine. Been going good for years and the engine stays clean.

But my engine is old and sloppy. It helps my oil pressure and quiets the racket.
