Loud Vavle Train Noise Question

[IZ1111]

I have a worn 92 crown vic that I enjoy using. But the engine noise is getting too much. I think my problem is that my oil pump is giving out and there's little oil reaching up the heads. So here is my question:

In theory If I were to take off the valve covers and pour a good amount of special noise reduction oil or even thicker oil on the valves, springs, rollers and shocker. Will the noise stop for a good amount of time. Will this work? Will I be wasting my time? Or is my problem something else.

No.

Worn engines can produce a symphony of noises, for may reasons. Sometimes it is difficult to tell the difference between lifter noise, piston slap, rod knock etc.

Therefore, it may be easier just to rebuild the entire engine.

Low oil pressure can be diagnosed by using an oil pressure gauge installed in place of the existing sender for the oil pressure light.

However, if you are looking for a cheap fix, try adding some miracle fix-it-in-a can in the oil after your next oil change. Sometimes they can work to free up sticky lifters. But they will often do nothing because the noise is coming from worn (not sticking) parts.

Sometimes, some noises are reduced by suing slightly heavier engine oil. Try 10w 30 or 10W 40 engine oil at your next change.

The repair will depend on the noise.

AF Moderator is correct in that rebuilding is the proper course of action. However, is this a cost effective solution? In what condition is the rest of your vehicle?

My experience has been that lots of noise is caused by dirty oil, or low oil.

Here's what I'd do.

1) Buy some "oil cleaner" (turns out it is usually just kerosene) to loosen up everything in your engine. DON'T RUN THE ENGINE VERY LONG since if there really is worn out equipment in there, the distillates will reduce oil pressure even more.
2) Drain the oil, and expect sludge.
3) Refill oil with Mobil 1 or some other synthetic oil.
4) Pray for miracles.

At one point I had what I thought was a broken lifter, clang was terrible. Using the steps above, the noise was resolved. That was 200,000 miles ago, so it was more than likely a stuck valve.

Be sure to report back to the forum what happens with your vehicle!
