engine anatomy 101- HELP PLEASE
Soon after blocking off the egr a rattle/knock noise developed. From the top it sounds like its comming from right under the intake close to the distributor shaft. From underneath it sounds like its radiating all the way down to the oil pan.:eek:
This noise is only heard when at idle, in drive or park. Has gotten progressively worse the last couple of days.
The engine doesnt get as warm as it should either, only about 145 cruising,160 running hard, but that may be a separate issue.
So I went hunting for the problem today. Removed the intake to check for obstructions, nothin'. Checked the dizzy gear, nothin'.
Since I am not that familier with how the intake and heads work together I got a question that may sound dumb, but here goes.
Am I seeing a single exhaust port on the intake side of each head?????
These smaller ports have a build up of what I would think would be carbon????
How do these work with the intake?? Could someone explain this? Do I have a problem with this buildup of carbon? Could that be causing the noise?
Mortec.com notes that these heads are 1987-up 64cc chamber 72'center bolt angle cast iron.
5.7LT GM crate-1993.
Are these the right gaskets??
Picked up a set of Mr. Gasket ultra-seal intake gaskets today. I noticed that the gaskets are solid where the smaller center ports are located. Only have the bolts holes there. Will these work?:confused:
The packaging states for 1987-1995 Gen I SBC.
Application heads:
14101083...1987-up...350..........Gen.I, also used on crate motors, 285 or 300 hp, 64cc chambers, 72' center manifold bolt angles. (Mortec.com)
