Update time!
So I've been trying to get the engine bay looking a little smarter over the last few weeks in time for Japfest this weekend, i had my bonnet closed all day last year as everyone had their shiny single turbo set-ups out and i wanted to make sure i felt proud of it this year. I also had an idle issue which i thought could potentially be a vacuum leak so removing the bits that i did helped me to check all the lines and make sure they were all in good condition, which thankfully, they were. The problem turned out to be my air filter being too close to the rad fan which was causing the MAF to get some inconsistent readings and mess up the fueling.
Right then! So I started by removing the plugs, coilpacks, leads and cam covers, i had new coil pack clips and lead clips to fit along with new cam breather hoses as all of that had gone hard and brittle and either cracked or wasn't pleased to remove. Whilst the camcovers were off i sanded them down, cleaned them up and sprayed them with VHT wrinkle black which i'm really happy with:
Before:
After:
As you can hopefully see from this pic when i re-fitted everything i used new stainless allen head bolts instead of the stock ones, looks a little nicer and won't corrode. I've actually replaced nearly all visible bolts in the engine bay now and it's made a really nice difference. I also fit new cam cover gaskets from Toyota whilst they were off.
Another small but nice change i made was i bought a modified water neck that had the 2 water nippled cut off, blanked, welded and smoothed, so that got the wrinkle black treatment too:
This is shortly after painting, it goes on smooth and gradually gets the wrinkle finish over about 24-48 hours. This also allowed me to flush the radiator and put some new coolant in.
At this point the idle problem was quite bad so i decided to strip down the inlet side and check for any leaks or problems, whilst also allowing me to paint that too:
Before:
During:
I found a few things that i thought could have caused it like the cam position sensor connector was covered in oil from my recent cam gasket leak and the throttle body had quite a bit of charcoal build up on it so i cleaned both:
Before:
After:
Not much else i could do other than check all the vacuum hoses and hope for the best, so i was onto the painting portion of things.
So everything was cleaned, scotch-brited or sanded, cleaned again with alcohol and them masked for painting.
And then just re-assembled, used new gaskets for both the inlet and the runners and everything was thoroughly cleaned before assembly, including the bits that don't really do a lot like:
Going back in with the new gaskets:
Done:
As a few of you may have seen i pulled the ETCS-i label off as i never liked it, i saw Supra_ufo last year put a zun sport badge in there and i thought it looked cool so i copied him.
Put it all back together and still had the idle problem unfortunately, i did eventually find out it was the filter though so i bought a piece of 4" silicone to extend the intake and sort the problem.
Whilst that was on the way i also bought a few more stainless nuts and bolts for the engine bay, a TRD oil cap and Whifbitz billet rad supports:
A bit more painting:
New wipers:
I only replaced my wipers last year with standard Halfords ones but BOTH had split in 12 months!! couldn't believe it, so this time i googled what were the best wipers and apparently it's these and so far they have been mint to be fair. And it says on the pack they last a lifetime but time will tell lol
Lastly i need to say a MASSIVE thank you to Mike (Delboy on here) for getting some SRD engine boxes out to me last minute that he hadn't used. I put a wanted thread up only a few days ago and he replied and send them out to me on next day delivery to make sure i got them for Japfest so a big thank you to you Mike, top bloke.
As for the engine boxes themselves i wasn't that impressed with them to be honest. Neither of them fit properly, so i had to cut both to fit, all the edges were very sharp and hadn't been de-burred properly so i had to sort that out too. Also because the corners and edges are so sharp it's incredibly easy to scratch the engine bay paintwork so i'll be putting some foam on the areas it come into contact with the body to make sure it doesn't. It's a lot of money for some bits of aluminium that's been cut to shape and welded for them not to be perfect in my opinion. Luckily i didn't pay full price.
Test fit:
After some cutting:
Still did more tidying up on them after this but got them to fit after 4 or 5 cuts in total.
And now they've been sanded down and painted but still drying and waiting for the wrinkle, they will be ready and fitted for Japfest though!
Just need to fit them and then give the car a good old spring clean and we're good to go! Looking forward to seeing everyone again, hopefully we can take home best stand 2 years in a row.
