Oil Leaking Onto Coilpacks

My R34 GTT has been misfiring even more since I turned the boost up to 10psi, finally got a chance to take her apart, wanted to check the coilpacks to see if they had any cracks in them.

Found out they a splitfires so pretty stoked about that, but as I started going through each one to check them and also check the plugs I noticed a lot of oil sitting above two of the coils.

Anyone had this issue before? I'm pretty sure it's oil, if it were petrol I would be able to smell it.

And is it safe for me to clean up the oil then take the coilpack out to check the plugs? scared I might get crap inside the cylinder head.

Thanks in advance!

Jaylon.

Oil in the cylinder head won't be the end of the world - anything that's collected in this oil will be.

Could be rocker-cover gasket leaking....degrease it, hose it out, let it dry (perhaps even assist it with a compressor) then remove them.

Cheers,

Got stuck into it again yesterday, I used paper towels to soak up most of the oil.

Looks like the guy that sold it to me lied about putting in new spark plugs just before i bought it haha.

It's so dirty in there I doubt any mechanic had been under there in a couple of years ay.

when you replace the plugs, gap them to .8mm (i kow this is right for the 33, not too sure bout the 34) and should help the missfiring. but clean all the crap out before you do the plugs, dont want anything falling into the holes for the spark plugs.

Hey mate, I had a similar issue with my R34. It could be the rocker cover gaskets but could also just be spillage from a careless oil change.

I cleaned mine up best I could before pulling the plugs out to prevent crap falling into the cylinders. My plugs are also gapped down to 0.5mm now as my coil packs on their way out, I will regap them to 0.8mm once I get a new set. Some further tips on resolving a misfire here.

Thanks, Yer I cleaned it all up pretty thoroughly.

Changed all the plugs as well and now there's no misfire!

The car blew the tiniest bit of smoke from the oil when I first started it but now it's all good.

Half a mission just getting into the plugs tho, I'll check it again in a couple of weeks when I have some more money whether I'll replace the rocker cover gaskets.

replaced my own rocker cover gaskets due to a leak, the gaskets and half moon seals from memory cost about $80 all up (both rocker cover gaskets and 2 half moon seals) and its a few hours work if you are comfy doin it yourself, else you shouldn't pay more than about $150-200 for labour if you cant do it yourself

Before you get all carried away replacing gaskets.....

....a screwdriver is your friend.

Tighten up any loose cam cover screws.

Good idea! I'll check for loose screws, if that doesn't fix it I'm able to replace the gaskets myself.

Yeah they are cheap, but I lost too much money at the casino this pay haha.

Can't wait till tax return, gonna finish off the exhaust with dump and front pipes, high flow cat, and FMIC :D

The gaskets will be fine, they are rubber and given the age of your car will still be fine. As has been said, retighten all the bolts holding the camshaft covers on. With heat they tend to loosen a bit over time.

      Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys

      Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels

      Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)

      I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.

      Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
