I did check in with the guy who dyno'd it and he's thinking it may be caused by the winter fuel mixture here in CA - says a lot of guys' cars run like crap on it..and the deposits on the plugs are most likely from the crappy gas. and now that the weather is cooler (70's), it might be running a bit leaner .. he's going to check his notes from our tune and give me a recommendation on different metering rods to help the AF ratio. Unrelated .. something is spraying on the front drivers side of the engine ... not sure where it's coming from ... there's not really anything over there! White deposits from... something.

My first thought was the gas. New blend for our west coast green states ? coolant level is right where it is supposed to be. Put new plugs and wires on runs much better. Plugs only had about 4k miles on them.

How will doing a cooling system pressure check while doing a compression check show something?

I guess that you missed the post regarding the white specks on the engine and it possibly being a coolant issue. A cooling system pressure check may display a leak which may have led to the white specks.

I can understand how doing a cooling system pressure check would help determine if that's an issue.. but how could doing a compression check at the same time show something? Just trying to understand what I'd be looking for ...thanks!

I decided to pull all the plugs to look at them (and replace them).. 7 of them looked like the images I posted previously.. then there was this one.. Am I correct in surmising that this was not firing? It was in the cylinder at the back of the engine on the drivers' side.. the hardest spark plug boot to get to, since the power brake booster is right in the way, and the plug boot rests against the header (I have fiberglass heat insulation boot on the plug boot).. 8331385-10756661_10152824553531675_583908826_o.jpg (121 downloads)

Not sure if the plug ain't firing or if it is fouled but I'd toss another one in (other 7 wouldn't hurt also) & see how it acts & I'd still do the pressure and compression tests cuz didn't you say earlier that something up front was sprayin out on the fender? EDIT I reread & it DID sound like I was sayin to do both at the same time Last edited by RapidRobert; 11/15/14 01:30 AM. live every 24 hour block of time like it's your last day on earth

Dribble some soapy water or spray some WD40 all around the intake manifold where it meats the heads while the motor is running. Should be able to see if there is a leak.
