New Clicking Sound from Engine Update! Reply #60 – December 18, 2010, 12:47:03 AM rotate your crank to zero deg in the normal running direction.ignore the distributor completely,, screw it , it has nothing to do with the valves opening or closing.remove number 1 spark plugstuff a screwdriver in the hole and you'll find your piston is TDC (either on exhaust or compression stroke)stuff a garden hose or something smaller in the spark plug holeblow like hell in the hose.if you can blow through the hose then rotate the crank one more revolution back around to zero again because you must be on exhaust stroke.feel for your piston being on tdc once again.If you can still blow through the hose then your timing is off by a tooth.if you can not blow through the hose then shag it,, move on to the next thing on the list.this is crazy and taking too long to diagnose. theres no reason to be still wondering if your timing is off or not.orremove #1 plugstuff the hole with barely damp paper towelbump starter barely several times or cross the starter solenoid with a screwdriver intermittantlyeventually the paper towel will pop outyour TDC mark on the crank will have traveled too far past the pointer so rotate the crank the opposite direction going a little too far past the pointernow rotate the crank to bring zero on your crank back to the pointernow stuff a garden hose in the plug hole.if you can blow air through, your timing is off by a toothif you can not blow air through then move on.report back.once upon a time i had an emission solenoid that was chattering when i was driving a certain speeds but i noticed it depended on the amount of pedal i was pushing ,,ie- the qty of vac being applied. The solenoid was chattering and was directly related to the smog pump system. Quote Selected

There is a small "slit" which looks like the gasket did not fill in correctly. I'll post a picture. What I'll do is when I get home I'll run the car, spray water directly there, and see if it bubbles, etc.There is a slit between the outside of the gasket and the portion that seals the water passages... In case of a leak, it's function is to route the coolant outside the engine rather than letting it get into the oil...To check the integrity of the gasket that seals the intake ports all you need is a vacuum gauge, if it idles 18in of vac or more you don't have a problem... Any leak that would lean the mixture enough to cause spark knock at open throttle is going to cause a very high idle(2000rpm or more)... Quote Selected

I'll post a picture tomorrow afternoon of what I am referring to. Maybe you can confirm if it's the same thing. Quote Selected

New Clicking Sound from Engine Update! Reply #64 – December 19, 2010, 08:26:38 PM These are the pictures of my intake where it almost looks like a leak. I put some rtv silicone there, just to see if the noise changed.. does that look like a gap to you? Quote Selected

Reply #67 – December 20, 2010, 09:18:12 AM Quote from: hypostang;346276Looks normal to meAgreed, gaskets aren't always cut straight across, so there often are small gaps... If you could insert a feeler gauge down into the opening, then there would be a problem... Quote Selected
