Hey Sparkie, check to make sure that you didn't suck an intake gasket into the port!

Jeff Taylor Is gonna dyno it and figure it for me if I can't get it. He treats me like family. I always feel like I am bugging him. I can't get there till thurs so I am trying to fix it myself. I have sent him all the info I gathered yesterday I will see what he thinks. He takes time out if his business to teach me things over the phone.

Mike T another class racer engine guy has spent countless hours with me giving me info.

I appreciate all you guys do for me. I love turning wrenches. It's something I really don't mind.
Frustrating sometimes but I wouldn't trade this stuff for nuttin!!

Billy I changed intake gaskets Friday night when I took heads off to check all gaskets!! I am like literally 5 minutes away from pulling the heads off. An just checking valves.

This is a new old head. When I left Florida I had a busted casting.

Re: May Day !! Down a cylinder
 

We tried 17 different plugs we sapped wires around we put new in wire cap everything. I worked all night Friday at Indy changing ing everything even carbs.

Only thing I didn't swap is the head from one side to the other. That might happen today.

Collapsed sealed power/speed pro style oil ring expander will do that and still show good leak . Just a thought ------

Re: May Day !! Down a cylinder
 

I can't take it lol. He's is off we are headed to peel son valves check some guides. Number 7 piston looks like it did when it came out of box clean as a pin. Other cyl have little black carbon on them from where they have fired.

Re: May Day !! Down a cylinder
 

What does the intake port look like on that cylinder. It could be a small crack or sand pit in the head casting allowing oil to be pulled in to that cylinder. You could do a vacuum check on that port if your machine shop has that type of equipment. You could have a problem with the oil ring in that hole too. It will leak check good even if the oil ring is not sealed. The expander could be lapped over.

Re: May Day !! Down a cylinder
 

Phil, is the plug gas fouled (stinks of gas) or oil fouled (you may smell some gas residue but no stronger smell than the other 7 cylinders)? My guess is an overlapped oil ring expander ( especially if it uses those damned Hastings Rings type of expander). Ron.
