7MG's tappety?

[Typhoon]

Would you consider these engines noisier in the valvetrain area than a modern hydraulic lashed engine? The rest of the engine is so quiet the valvetrain realy stands out. Not that it's abnormally loud, I guess the advances in hydraulic lash and NVH design really show on these older, cam over valve engines?

are you sure you aren't hearing the injectors? Stock minus the injectors the car is ultra quiet

Yeah the valve train is pretty quite, but the stock injectors are loud as hell. I can hear them inside the cabin (barely).

I big Ditto to all above posts

If you were replacing the injectors stock for stock - ie - with 440cc's, would new OEM ones be noisy, or would you be better off going for Bosch/RC/PTE?

Have you checked the valve lash?

Remember, these are basically solid lifter setups - they require periodic lash check and adjustment, and will never be as quiet as a hydraulic setup.

Factory ones are noisy. Changing them to an aftermarket injector might be quieter. I nice my 550s don't seem to make any noise.

sorry to jack, would heat affect the ticking? injectors or valve train.

(cold car doesn't tick, once it is up to operation temp, it ticks)

The valve train can be noisy, especially if the valve lash is greater than spec, like mine.

I have a pretty loud ticking from the top of the engine....i'm guessing its the valve train or a bad injector.
