My intake manifold leaks like a sieve
Operator error
I had the engine professionally built and it ran fine for 50k miles
Decided to put on some new heads so I grabbed a set from junkyard and had machine shop work them over.
Then I installed the fresh heads and now I have this leak.
So the leak is my fault.
There were no alignment pins in the block or manifold when I removed the manifold initially.
I guess I need to go back and ensure I install the alignment sleeves correctly
