Prollly asking for troubles. That said, if you have the OEM stone tray underneath, you'd have to be pretty unlucky for something to go through the belt / teeth.

In these circumstances, i always imagine what i would think if the worst case scenario occurred... I'd kick myself.

Id leave it on.

Asking for trouble mate. Anything that falls at the front of the motor will end up behind the harmonic balancer. If you leave it there it will destroy your timing belt and then engine. If you notice something falling there it is balancer off to retreive it.

They get left off because it either looks good, or because it makes it easier to adjust cam gears.

Either way its not a good idea

I cannot see any reason to leave the cover off unless you were having the car tuned on the dyno and needed to adjust the cam gears as part of the tune. After that I would always have a cover on. If it is a look thing that you are after they now make clear covers for RB26 and RB25 motors.

I have first hand experience with the type of problems that can occur with an open motor. I once dropped a 6 mm bolt down past the timing chain in a Mazda engine. After much effort we finally got it to fall all the way through and into the sump to allow me to retrieve it by removing the sump. This took TWO WHOLE DAYS to get the bolt out and an unbelieveable amount of frustration along the way.

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
