ok, giving the car a massive going over and it's time for the engine bay.

problem is, i'm a noob when it comes to engines, and i don't know what all the bits and pieces are. So when i started cleaning yday i was worried about pretty much everything getting wet :down:

Which is silly, because i drive the bloody thing in the rain, and i know it gets wet in there...

anyways, i've got a pic that i hope will help

RIMG0201.jpg

stole this from a for sale thread, hope the owner doesn't mind

1. Back wall/drivers side, ok to spray there? (there's some big round thing mounted on the wall)

2. back wall/passenger side. There is a silver box thing there (abs?) that doesn't look like would want to get wet

3. down side of engine and side of driver's side strut tower... a lot of plugs/lines etc there

4. Back wall/middle - again, quite a bit of electronics back there... i'm guess leave that back wall middle section?

5. Down turbo side of engine, where the power steering fluid bottle is

6. Fan area

7. Front of engine

Obviously i won't be going near the battery area, and the headlights.

From the numbers, what should i be leaving well alone and what is ok to spray?

Or are there really only a few things that should be covered up?

cheers,

daniel

all around the edges is fine to spray... put a plastic bag over your afm and your air filter..

take the engine cover off... do not spray the top of the engine... from the manifolds down you can.

just do the top with spray and wipe and a rag..

then cover the whole thing with silicon spray or tyre shine and wipe it off.... this will give it a nice sheen.. but more importantly... will make everything real easy to clean next time.. and the time after that, and the time after that.

keep your hoses nicley sheened and it will look good no matter how filthy it actually is.. faded hoses are the worst.

I'd cover the top of the engine, where the coils are, with a plastic bag, water can settle here around the spark plug holes and you def don't want this.

Take the engine cover off (clean it while he's off :down:) then put a big bin liner or similar over the cam covers and in between, stuff your air intake with a towel/rag then everything else should be good to go, cos as you say, shit does get pretty wet in there when your driving along on a rainy day...

Important though, make sure your car is left to thoroughly dry after, and is stone cold when you clean it.

If the engine is hot, and you spray cold water on it, things can damage, easily

Agree with Hamish & Craig.

1) Degreaser &/or Armorall

2) Cotton rag &/or Microfibre

3) Chopsticks - Japanese type with pointed end & blunt end to poke around with the rag &/or Cotton Buds

Great stress-reliever after a shitty week.

If you are going to use Degreaser- word of warning,This stuff is Highly flammable. Only a few weeks ago I took my daily for a degrease to one of those carlovers type places.I pulled in to the wash bay and lifted the hood to let it cool down for a few minutes.After this I started spraying degreaser in selective areas.Then some of the degreaser must have dripped onto the exhaust manifold and BOOM !! Up in flames...First reaction SHIT !!! , Grabbed my wallet ,panicking searching for a coin to shove into the slot to activate the pressure cleaner. Could have filed my nails while I waited for it to start with trigger on full,Meanwhile 3 foot flames have totally engulfed the engine bay.Finally out comes the water pressure and flame dies...Go toi start car...No problem whatsoever, As it was only the degreaser burning and nothing else even got touched...

Dont repeat my lucky error

Make sure exhaust area is cold before spraying this stuff

I've cleaned plenty of R33 & R34 engine bays while working at a RAW. We used a product called Reb Baron degreaser. Sprayed the entire bay, left it for 5 minutes and then used a high pressure sprayer to remove it. I did the entire bay without covering anything and never had a problem.

I also did this to my personal R33 once every few months and never had a problem in 5 years. After it dries I used either Amoral or silicon spray on any of the plastic parts, always came up looking great.

yeah as above post I laways spray mine at the car wash with degreaser then hi pressure it off. Just cover the air filter or if u got stock airbox make sure the snorkel is dry, just dont get carried away and stand there for 10min spraying thats when youll cause problems

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      R33 persistent issues. P/steering and lag/misfire

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
