What is this stuff? all in my vacuume ports/fittings. Is this what is messing up my motor?
I'm amazed any AIR could still pass throughthe fittings! How should I clean the upper intake??(my self, not taking it anywhere)
***UPDATE***
I started to do a compression test. I did NOT warm the motor up first, since the upper intake is off. There is something else going on, I don't think it's a head gasket. I cranked the motor over and the #8 cyl blew 180PSI the other 4 I tried #4,5,6 and 7, all blew 170-180PSI.
I took more pics. Look at this first one closly. See where the intake port meats the cylinder head intake port, at the gasket? See how it looks brand new?? Well they ALL look like this EXCEPT #8.
Now look at the #8 cyl. See how in the actual head there's all that build up?? WHAT IS CAUSING THIS?? My theory was a messed up injector, and that may explain why it would hang at 2500rpm's for a few seconds when the throttle is released before it settles back into idle.
The #8 plug has those deposits on it, and looks like high-speed glasing/ Detonation?? WHY??
