It's nearly time to put it away....but not just yet
Where has the summer gone? I seems like only yesterday that I was getting the car out of it's winter hiding place only now to see it's time to put it away again. But with the weather forecast this week I don't think I will be putting it away just yet.
So far this year we have only covered about 2500 miles, and these haven't always been without an issue or 2.
A few weeks ago, the engine developed a serious thirst for oil, consuming about 3/4 litre in 200 odd miles. With no sign of obvious leaks this means it could only be going one way - out of the exhaust!!
So after a bit of investigation, with no oiled up plugs, very dry cylinder bores across all pistons, a lack of smoke from the exhaust under hard acceleration or on start up it started to become a bit of a mystery as to which cylinder was burning the oil.
After a bit of research and a bit of head scratching online, I ended up coming back to the MX5 owners 'must have book', Rod Graingers guide to all things MX5. This book has been a godsend during my build. And looking back at it I should have refered to this book from the start, under diagnostics at the back, a section entitled 'excessive oil consumption' to which it's first port of call Is the PCV valve on the top of the engine being faulty, I read on one site some where that if the pipe that goes from this valve to the inlet manifold was wet with oil, it was likely that the valve had stopped working causing the oil to be burnt. Off out to undo the pipe on the car and guess what I come across, a very wet and oily pipe. So a new valve was ordered and fingers crossed after a few hundred miles things seem to be running ok.
Also are some pictures of the LED light upgrades that I purchased at the kit car show, these were well worth the money and are seriously bright bits of kit. I will do any thing to make sure that I am seen by others road users, one thing you get to learn whilst being out in the car is that other road users do not see you what so ever. So with some bright brake and indicators I am doing my best to ensure this is not the case.
