Hi,

I seem to have an issue with the car battery. I had not driven my car for about a week. My third party car alarm still makes the beep, however the factory central locking (which can be found on the key itself) does not work.

Basically all electrics do not work as well as the obvious, i can't start the car.

Question is does this always happen when you don't drive the car for a long period of time. Also i'm thinking of replacing the car battery itself as the battery is really quite small compared to the other batteries i see. Can i buy a replacement from say SuperCheap or Autobarn and which model of battery.

Cheers

a week isn't exactly a long time. i had a car sitting for 8 months and the battery still had enough charge to turn it over (but not start it).

it could be caused by 1 of 3 things. you alternator isn't working properly (not charging the battery fully). there is something in the car that isn't functioning correctly and it is draining the power off the battery when the car is turned off, or most likely, the battery is dead. if the battery is a few years old then i would put it down to it being the likely cause, especially as the nights are starting to get cooler. winter is always the time when weak batteries start to die. they can be fine 1 day, then the next day won't even have enough charge to turn the car over. then you can jump start the car and drive to work, leave the car all day, go back to it in the afternoon and have it start straight away, but the next morning it will be dead again.

so if the battery is 3 or 4 years old, i'd invest in a new battery before bothering to look at other things as it is the most likely cause.

      That cannot have been a fun set of drilling. The stock "baffle" looks identical to rb26, I just cut fuel cell foam to fit the full length under the baffle.

      I understand your sarcastic exasperation. But to be fair - the baffles do indeed fit OEM cam covers. They did omit to say that you need to do a bunch of stuff. But they do fit them.

      Got started on the modification to make these splash plates fit over the long weekend. First the surprisingly time consuming task of swapping all the cam cap bolts to Tomei cam cap studs. I did the method of removing one bolt at a time, applying loctite to the stud, double nutting to torque as the manual described. Then carefully unlocking the nuts without disrupting the torque of the stud (and going back to re-torque a few times when it slipped). Finally applying the nut and torquing to spec. Repeat x28 Next up I went about removing the stock cam cover baffle so I could ensure it was fully clean after drilling for stud clearance.  As the blind rivets holding the baffle on were domed I used a punch to mark the center then used 4mm drill bit to carefully drill out the rivet without going too far part the baffle. As seen in other thread here is what is inside the stock baffles I decided on M4x6mm bolts to bolt the baffle plate back on with. I used a 3.3mm drill bit with some tape to mark the depth at ~8mm. Next was to tap the threads using a cheap bunnings kit M4x0.7. With the baffle removed I also drilled out the spot welds holding in the baffle plate oil returns. Unsure whether this was the best option or if I should have cut holes in the Hypertune splash plates to allow the oil drains to still function... time will tell. I then removed the the Hypertune splash plates so I could rest the cam cover on top and use a dab of grease to mark where the studs impacted the oem cam cover baffle. The most obvious spot was on the hump from the stock mesh is held. Using this hole as an anchor I bolted the oem baffle plate back into the cam cover and lined up the Hypertune splash plate. Marked the rest of the holes for the studs and drill those out too. Total 32 holes drilled and 12 threads tapped on the passenger side cam cover alone for this bolt on part that totally clears all OEM cam covers.. Drivers side next as well as some E85 safe fuel foam to fill the space behind the behind cam cover baffle plates. oh and some lock nuts for the splash plates of course.
