Thread: Mach spark plug help

Figured I would change spark plugs In hopes of fixing the tugging at low rpm. I went from tr55's to oem..was that a good choice? Also some plugs had a little oil around the top and one other had pretty bad rust...would this mean a bad gasket I'm new to these motors?? Any help would be appreciated thx

No it means the valve cover gasket is leaking oil around one plug and the coil cover is leaking and letting moisture get into the other plug

Oh ok it's on the driver side valve cover would it be a tough fix?
I also noticed the glass part had burn marks on it : /

It isn't actually the valve cover gasket. It's the coil cover(s). It's usually a rear plug where the water gets through an opening where the wires enter the coil cover. Because of the deep holes where the plug sits, the water gets down in there and rusts the plug.

Just put a small blob of RTV on the wires right where they go under the cover and bolt down the cover.

Thanks for the help guys really appreciate it

That won't solve the oil issue though that is the round seal under the valve cover

Yeah, I missed the oil part. He's correct, that's the round seal.

Would that ring be hard to fix?

You have to pull the valve cover it is one of the gasket pieces in the valve cover gasket kit.
