hey there everyone, I was out and about today in scarborough and on the way back, I ran into a problem. Cylinder 1 on the car is whistling..... When i am de-accelerating or idling, the sound is M.I.A. But when I am on the gas, the whistle is there. Not sure if i popped the gasket and now it needs to be replaced, or if its anything worse...... Please let me know ASAP if you have any info.

could be an exhaust gasket thats blown out.

the blow by is on the back of the block where the intake manifold meets the block. Would it be the intake manifold gasket?
