That would be terrific. But while in town a while ago I stopped by two shops. Neither, as it turns out, performs deep engine repair. Both mechanics speculated about me having possibly dropped a screw down the intake and into one of the cylinders. Suckville. Worse than an oil pump. Plus if that angle pans out it might have been caused by my carelessness.
That puts me back at afraid to start her again. One of them did recommend pulling the plugs for a look inside with a camera and maybe for scratches on one of the plugs. Excellent idea. All the information thus far obtained means that probably tomorrow I will pull those plugs and see if immediate danger of worsening the situation by running at all or any more is apparent upon inspection. Gotta love working on automobile engines, eh. Thanks for the input.

There is a rapid, fairly light knocking sound (probably not a rod) that reminds me of what is often heard when first starting older engines that have sat at least a few days. The kind that generally goes away after 3-5 seconds.[/quote]
A quick search turned up that the engine has hydraulic tappets, which supports your description and recording of the noise. My car has hydraulic tappets and I remember the owner’s manual stating that the noise may take several minutes to go away if the engine hasn’t run in a long time.
Your first set of short runs got oil to the top of the engine, so you can probably raise the RPM a little or just let it idle and warm up normally, keeping an eye and ear on it. If the noise fades after 10-15 minutes and everything checks out, you’re probably all set for a test drive. I would also recommend changing the oil & filter soon, along with a general inspection of other fluids and systems if you haven’t already. If the noise doesn’t fade or gets worse, it might be time to seek a mechanic.
Best of luck to you :)[/quote]

[quote=”lovemyhyundai” post=99502]You think maybe it could be a timing belt issue? My dads honda was making the same noise and I had to get someone to change the timing belt and do a timing adjustment on it after.[/quote]
I would expect misfiring to be present if timing were off that far. Plus I never made any changes to that area of the car. Only took off the intake manifold. With the Honda, you are saying a similar noise was cured though. Surprising. Let’s find out if others might have a take on the symptoms and your experience.[quote=”lovemyhyundai” post=99502]You think maybe it could be a timing belt issue?
