1967 mustang with stock 200 six. Engine has only 25,000 miles on it since being rebuilt by a local speed shop that is now out of business of course.
Oil is being dumped into 2 of my cylinders. #1 and #3. Plugs foul out in those cylinders in only about 5 miles of driving. If I remove the plugs and shine a flashlight in there I can see the cylinder walls are wet with what must be oil. The others cylinders look dry and do not foul out the plugs.
I don't see any signs of of it being a head gasket. No oil in coolant or coolant in oil also amazingly the car does not smoke at all as far as I can tell.
Was hoping it was stuck oil rings and just did the Marvel Mystery oil soak where you pour MMO into each cylinder and let it soak for a couple days to free the oil rings up. All of the MMO drained past the rings and the car did not smoke at all after that either. I added 1.5 ounces to each cylinder twice, let it sit and rotated engine by hand a few times. Spent a total of 48 hours doing that whole thing. Did not help at all and brand new plugs fouled out again in those cylinders the same way.
I have previously removed the valve cover (first thing I did when this all started) and verified the valve seals look good. Now I'm thinking it may be bad valve guides. I plan to remove the valve spring on #3 and wiggle the valve stem to see if there is any play in the valve guide and go from there. Actually hoping I find something screwed up so I can get the car fixed! Don't want to pull the head and have it worked on just to later find out it is broken oil rings.
Guess I took the long way around to ask my original my question.
What valve spring compressor should I buy that will work properly on my six? Thanks!
