so i have an update i took my valve cover off and i found coolant in the second sparkplug chamber, i cleaned it up thinking i just spilled some in when i took the valve cover on so i put my old sparkplugs in put the car back together and took it for a drive, it started misfiring again after about 20 mins this time so i drove back home and took off the valve cover and then again i have found coolant in the second sparkplug chamber,

Well thats good you found it but a mystery as to how it gets in there.

Coolant in the spark plug bores can only get there from a cracked head.

So there is no coolant on the spark plugs, just where the coil is sitting I highly doubt I cracked the head when tightening the plugs hahah

OK....Riddle me this. Where is the coolant coming from, to get from the inside of the head to the outside of the head?  Where is the nearest coolant?  Is it squirting from a hose and somehow finding its way under the coil cover?  No, of course it isn't. The coolant is running in galleries in the head. There is either a crack, or a welch plug is leaking.

Update: so now car is misfiring on startup and engine light comes on right away, but after i go to second gear the misfire stops and wont come back. car drives completely fine but has the engine light on and then when i restart my car later in the day this happens again but i drive it and the misfire stops

I had similar issues with a cracked block, multiple times. What was happening is on low rpm the coolant pressure was enough to get into the bores and cause a misfire. Rev the engine enough and combustion pressure was enough to push combustion gas into the coolant, so while it wouldn't miss... it was very obviously pressurizing the coolant.

This will get worse before it gets better. Pepare yourself for replacement engine time.

Misfires and Coolant being in places it should not be is never a good combination.

so the coolant is only getting into the chamber when i take apart the hoses so its just leaking in there. i am pretty sure i have found the issue i decided to unplug all the coilpacks and one of the plug connectors wires wernt in the connector all the way so i took it out and it fell apart in my hands

    • Anyone want to make me an offer to take my v36/g37 3.7l manual coupe in full? Off memory it was low 100k km but the battery is flat so can't tell right now. What's wrong. I had engine problem's that led to a nice clunk. It made it home but it wasn't pretty for the last few kms. Happened under revs. Sounds like bottom end.. never got around to fully checking or fixing it so the car has sat still and unregistered for a few years. Minor bump in front end set the pedestrian protection under bonnet airbag off and that was meant to be repaired, but while waiting for the repair (parts to come) I got the engine problem. The rest of the car is in decent condition. All drive line is good. All interior is good. Leather interior. Wheels in good condition and decent tyres although the ps4s are likely a little too old now it's sat still. Colour of the car is pewter off memory, the dark grey colour. In Camden NSW. Would need a tray back pickup.

    • I started with the above in my head too, and I might be reading / thinking about what they want wrong, which is why I complicated it a bit further. Purpose I'm seeing is for the corner indicator to be on with headlights, and then if the indicator turns on it can still flash. The relay part above I can see working as required, except in the case of headlight is on, and indicator is on. The change over relay you've wired in would get signal from the indicator, and as it flashes would give power to the globe from the indicator, but as it flashes off, power comes from the headlight, which would cause the indicator to be constantly on when headlight is on, even while indicator change over is flashing. That is unless we don't care if it flashes or not if the headlight is on? I guess that's an OP clarification.
    • HI, Ive got an r34 gtt sedan A/T. The instrument cluster went out and I replaced it with another A/T everything visually looks the same and all the gauges work now with the exception of the speedometer and odometer. The speedo will stay pinned at zero until I'm going about 55kmh and then it'll say Im going about 5kmh. my odometer seems to be tracking at about a 1/10 of what it should. If I go 1km it'll say I've only gone 0.01. Appreciate any and all help. Ive tried searching through the forums reddit and a local fb group. The only info I think I've found is that some cars didnt come equipped with TCS (mind is) and the clusters may be different between those? I've also installed a brand new VSS and no joy obviously. TIA. 
    • what speedo healer did you use?
