Need Help Asap. Car Is In Pieces

[Musky]

Hey guys,

Did a quick search and couldnt find wat i needed and im in a bit of a rush as the cars apart etc...

Ok so i just did a comp test and results are:

Cyl 1 - 165

2 - 160

3 - 160

4 - 155

5 - 160

6 - 170

As far as i know thats not too bad besides cyl 4 being a lil low. Anyone care to enlighten?

Ok next question. On cyl 3 and 4 there was oil underneath the coilpacks. Ive taken a pic to show wat im talking about. Now just last week i had it at tuners and he did a comp test, where upon he told me the compression was low but didnt give me the readings because he forgot. So i wanted to know how low and which cyls was low so i can diagnose the problem etc. Could he possibly have done a 'wet' comp test and this be spilt oil? Im not sure...

Next ques. One of the spark plugs had more black residue around the head than the others. Once again ive taken a pic. I think it was the 6th cyl sparky. Anything to worry about here?

Last question. The other reason i wanted to pull the car apart was because of a misfire my car seems to be having. Its got 5 splitfire coilpacks and 1 yellow jacket coilpack, reason for this one splitfire melted aand couldnt find an individual one to replace it. Anyone see a problem with this?

Now also the spark plugs that are in there are NGK V-Power R5671A-8 plugs. Im assuming the -8 means there gapped to 0.8mm? Are these good spark plugs for my mildly modded r33? This is why im in a rush, cuz if they not so good then i'll need to duck out and replace them while the cars apart....

So after all that i thnkyou for ANY help that is given.

Regards

Struggling noob....

fwiw heres my take on a couple of your probs. The oil in the valley is more than likely a leaking tappet cover gasket.

That black plug is probably telling you that is the cylinder that is causing your misfire prob. Check your coil pack on that cylinder or your loom.

Hope this is of some asistance to you.

Excuse me for my dumbness, but is a tappet cover the same as a 'rocker' cover? As wehn it was at the tuners he replaced teh rocker cover because it was leaking, so id be happy with that result

I will check over the coilpacks and wiring, just after i have lunch

Good man, any help is of assistance and ive generally got no idea...

Yes, same thing.

Thanks mate

Just did a bit of a search on those spark plugs and it seems the -8 is the heat range which is 2 heat ranges colder than standard apparently...

The compression is also fine mate, motor is a LITTLE tired but its fine.

As much is to be expected from an old motor, it will still do what an internally stock RB should do if you keep up the maintenance as you should.
