Water & Brown Sludge Etc In Spark Plug Holes :(

Hey :)

I just bought another Skyline- an R33 Series 2 Mspec manual for very cheap (even suspiciously too cheap) due to un ergo, hole in exhaust (came with new full stainless steel one), misfire at boost problem which they said prob coil packs and interior dash lights and indicators don't work. Picked it up tonight and of course as was cheap I figured there will be a fair few problems I would need to sort out which is of course to be expected.

Drives great except splutters and chokes itself under boost. So far all the intake pipes and throttle body are absolutely filthy and it stinks like contaminated oil where the throttle body connects and the a lot of the hoses are bad and cracking which is all fine I can deal with that but what worries me is this-

Every single spark plug hole has heaps of brown sludge and water in there :( a decent amount as well! The coil packs look like ass so of course will replace those and the spark plugs. Firstly, what is the best way to get the water and crap out before I pull the plugs? And does the sludge and crap sound like a head gasket??? Please tell me there is something else it could be!

I will take some pics soon! Any help would be greatly appreciated!

Thanks

I pulled the spark plugs and there is no water or oil or anything down there so that's good right? It seems like water accumulated on top as there was mouse crap too and a cockroach leg lol but yeah nothing under spark plugs

Clean up the entire engine bay and vehicle. Have a really good look over it, - Decide if it is worth spending effort and money on

Are the chassis rails straight, any rust, steering components, tyre wear, brakes, oil/water/air leaks, lights

What info did the previous owner give you?

Have you done a fast and revs check?

If keeping

Give it a major service including a good engine flush (Liquid Molly or Wurths). All fluids, plugs, filters

Did you get any service records with it? When were the belts done including timing belt

then go through and list all the remaining obvious issues standing still, then take it for a drive and list any running issues. get an idea of parts and prices (does it scare you?)

if not attack them methodically/logically

What aftermarket mods including ECU?

For the In cabin, dash lights and indicators - verify all fuses and relays

Sludge is from leaking covers and water laying around

Being a 96 33 GTS-t I expect your young and your budget is minimal

As you said there is a reason some cars are cheap.

Some times you can get a gem that just hasn't been maintained

Hey Sinista,

Thanks for the info! Haha yes student at the moment so relatively tight budget but all my money ends up going on the cars so if it needs to be fixed it will usually be done!

Have a service history with log book etc it came over from NSW so have the dates for belt etc. Chassis is nice and straight surprisingly minimal rust it's quite clean.

I managed to replace spark plugs but its going to need new coil packs considering they were submerged in water and muck. I use liquid moly on all my cars so will be putting some of that through. I don't like the BOV I want to remove that for now and just put it back to stock as will need it for pits anyway. Ran OBD no codes which is boring, other parameters seem good but not relying on that!

Coolant system seems good but will flush anyway, oil looks good etc. the car was sitting for about a year only driven every month or so.

Mods are basic just the crappy rusty looking blitz BOV, boost tee (not a fan will be removing that), HKS rear muffler, cusco strut braces, apexi air intake, aftermarket suspension- mainly cosmetic.

Since cleaning throttle body and pipes the car will start straight away idle for a second and die. Going to have to see if I put a hose on the wrong way or something- could mega vac leaks cause that?? A lot of the hoses are suspicious!! I will take some photos now of how the BOV and boost tee have been set up its all weird to me as my other one was completely stock.

Sludge around the spark plugs simply means it's had an engine degrease by someone who was rather happy with the hose. This has screwed the plugs and coils. New coils and plugs and it will probably run well.

Exactly what I was thinking. Quite possibly had the valley cover off while cleaning and have since put it back on.

Does look pretty nice for a cheap one, series 2 as well so if its just coilpacks and plugs that need replacing id be more than happy with that

Thanks :) I reckon she is pretty hot it's worth more but he had too many cars and a newborn so he just needed it gone. Good thinking guys! I found out it was actually a degrease! Why wouldn't u cover up that area though?

It's driving so much better and haven't even replaced coil packs or exhaust yet!

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
