I was reading another thread regarding plug gaps and cutting the plugs back, and I decided to take a look at mine.


Plugs are not fouled but the threads are.
I checked three and all the same.
...sorry for the bad pics, I was too close.



These plugs (R44T) have approx 40 miles on them. I was using R44TS but the carb was too rich and the timing was off. After I tuned the motor I switched them out. The motor is new with only about 125 miles, and seems to be running really strong.

Heads are World S/R Torker, and they recommend these plugs for the heads. It appears to be motor oil and not fuel (am i crazy...?). There is no oil leaking from the gaskets and settleing there. The valve seals are Crane Teflon, forged pistons and moly rings. Compression test last week showed all cylinders between 170-185psi. No big cloud behind the car while I'm driving.

So what gives, anyone have any ideas?

They look fine for a new engine. You will always have some oil burning on a new engine. It will settle down after 1000 miles or so.

Due to the oil on the threads it sure does look like a valve seal problem. Hmmm.

You might wanna try a plug one step colder as it will help prevent pre-ignition which is common in higher compression engines that see heavier loads like yur modded engine. if you step down one to R43ts you can get them in comercial grade. thier # is CR43TS. its what im running in mine with good results. I snapped a couple of pics below so you can see how much beefier the CR's are. CR on the left, R on the right. Of coarse you can see that one is used and the other is not but you can still see the difference in the electrodes. i pit a link as well to get a blown up pic if you want.

Give those Moly rings a chance to seat. Oil on the plugs threads is common on new .. Also might want to check your intake torque , might be seeping a little oil..

The plugs look fine, if they are black then you need to start worrying.

The Moly rings should seat in upon cam break-in. :cheers:
