[V8] Oil cap

[D Morralee]

Thanks Tom. Did some more testing on the weekend and car was a little better when I took it for a drive  ran fine and then started to feel like it was running on 7 cyl. I did a quick test to check (rag test) if the exhaust valve was sticking before I took it for a drive. Also did vacuum test and everything was good. When I came back from my 15 min road test and the car was acting up I did the rag test again. Those of you who don't know about the Rag test ... Place rag at exhaust pipe ... If it gets sucked into the exhaust pipe it indicates a problem with one of the exhaust valve ... If the rag just flutters everything is good. I forgot to retest with the vacuum tester. Going forward I'm going to try some sea foam in the intake manifold and track down some of that ring-free stuff. Thanks to all for your feedback. Superdave !!

Hey Dave, While I've used Seafoam on all kinds of motors over the  
years, If I was going to try and get some results, I'd suck it right  
into the intake manifold via  one of those ports near the intake(air  
cleaner).....you don't want to flood it with the stuff as it will  
stall, so aim for smaller vacuum hoses.  I've posted this before, but  
I run Yamaha "Ring -Free" in my 130hp 2 stroke outboard.  It's a 1 oz/ 
10gal ratio, and is a concentrated "carbon removal" liquid. "shock"  
treatment is also a meager 2oz/10gal. This is definatly not Kerosene  
or "Seafoam"(Kerosene/Jet A).  My Yamaha guy in town went bankrupt 2  
years ago, and last year I ran the boat without it as I couldn't just  
buy it in town.  It still ran great, but took longer to start.  When  
I pulled the plugs this march, they were gooed up/carboned.....I got  
a jug recently, and accidently put about 8 oz in the tank on the boat 
(42 gallon tank)....... and ran that tank out.....The plugs were now  
shiny new looking and the top of the piston I looked at was clean/ 
shiny......I put this same stuff in the parts car before parting it 
(had 2 plug wires switched for however long), and it made a  
difference on those gummed up cylinders.  I've got a 1/2 gallon of it  
right now, but pretty sure I can't sent it across the border.  If  
there's a snowmobile/dirtbike/outboard place near you, they've  
probably got it.  It's MSDS say's for "Gasoline engines", but the  
only people that use it are the 2 stroke people......I'm a  
believer....Put THAT in the tank, and run some seafoam thru the  
intake.......Tom
