Oil In Sparkplug Well

As the title suggests on my 33 I have a nice big pool of oil in my sparkplug wells.

Unfortunately I haven't had enough time to inspect the problem closely- Spose it'll be a Saturday morning job now....

Seeing as I've only just bought the car I'm hoping that maybe the previous owner has fixed a bad leak from the rockercover gasket and not thought to clean up the leakage properly.

I plan to suck all the oil up, clean the plugs, coilpacks and head and take it for a drive to see how quickly the oil comes back.

I've heard there are sparkplug seals down in there somewhere but I can't for the life of me picture what they would look like, where they are and how hard/expensive they are to replace...

Anyone had this problem that could tell me what I might be in for? :P

im pretty sure by memory when you take the rocker cover off there will be O shaped seals down the center of the rocker cover once it is removed, it wuldnt be to expencive and the seals shuld come with a new rocka cover gasket.

Hopefully thats all it is then and I should be able to see pretty easily if thats the problem.

I was told by an NRMA roadside assistance dude that there are sparkplug seals or atleast seals near the sparkplugs that would be leaking (He took a 5 second look at it when my car broke down yesterday -which is another story) can anyone elaborate on this?

yer those would be the seals he was talkin about the ones i explained above, if it is not that then its a different ball game as at work we have had oil soaked the spark plugs and it wasnt the seals some have been a head gasket and in worst cases piston rings but lets hope its just the seals aye lol.

      Help! Leak coming under transmission

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
