listen to my engine , tell me whats up

[emosun]

So I made this video for you to listen to. The engine itself has a very diesel like sound , and the muffler has a very metallic like sound. This is the car cold and warming up. The outside temp is 36f and the car was not up to operating temp. the engine gets a bit quieter when you drive it , but the exhaust always has that metal like sound.

Also the smoke coming from the engine , I think , is a leaky oil pan or pan drain plug , because it absolutely reeks of burning oil so I think it's leaking onto the exhaust.

But I'm more concerned with the noise right now which I'm guessing is that the top end needs some adjusting or fixing of some kind.

My 2000 accord is the same way, it has 225,000km.

Problem = car is old. Lifters ticking.

My car has rings starting to go (smell burning oil when I step on it going up hill), ticking lifters when cold, and many other little issues.


How many miles/km on the car?

How many miles/km on the car?

217,000 miles , which shouldn't be a lot for a cb9 , so it's only the lifters and not the rockers or anything else?

My old f motor sounded similar to this but it would quiet up a lot when warmed up. I didn't worry about it too much as I had a swap waiting but never did cause me any real issues.

[Raf99]

217,000 is a lot. The sound is the lifters only.

You could try adjusting the valve clearance.

[Father Time]

Do both of these..... (ok so 3 of these lol)

Check oil level (it sounds like that when it is low)
Check your valves (Eric the care guy has an easy way to do it)


Also......check your exhaust bolts from the CAT back to the tailpipe as well.

Valve adjustment, and while you're at it, replace the valve guides and an oil change. 10W-40.

If the vehicle wasn't completely warm, start preparing for a new head gasket. If it was still warming up as mentioned, you may be fine.

[Kev1990]

Do exactly what Straight Success said to do and once your engine is warmed up very slowly raise the rpms and listen for any engine knocks. If it takes your engine a long period of time before it gets warm I would replace the thermostat even on the coldest days as many cb7s I have-had normal warm up time would be 5-7 minutes I had a couple that took 15+ minutes lol.

Some good info in here and some not so accurate info as well.

First, how is the oil level? How long ago did you do a valve adjustment?

Before changing the recommended oil viscosity, does the motor consume oil? Has the oil pressure dropped? Fix the leaks and recheck oil pressures at both cold start up and at warm engine temps. If the pressure has indeed gone done, go with a thicker oil like the 5w40 recommended by someone else.

To replace the valve guides as stated above will require a machine shop to do, at which time you will need a new head gasket. Might as well rebuild the head.

As for the statement regarding valve lifters, these engines don't have valve lifters.

Thing sounds better than my sedan, I can't really hear anything but the lifter tick but both my cars sound like that.

I think the valve lifter comments were meant to say valve lash. Set your valve lash.

[Fleetw00d]

As stated, make sure oil level is correct. Set valve lash. Intakes are 0.010 +/- 0.001, exhaust 0.012 +/- 0.001. I tend to set mine on the tight side, this seems to minimize clatter at start up and they are quiet when at temperature. You don't want to go less than the recommended or the valve may not seat correctly when warmed up, allowing leakage and possibly burning a valve.

If the burning oil smell is from under the hood, not at the tail pipe, a common source of a leaks that drip onto the exhaust is the oil pressure switch above the oil filter and the oil pan.

As far as the metallic sound of the exhaust, check the heat shields on the catalytic converter (these tend to rust away at the four mounting bolts) and the heat shields on the underside of the body.

Yes; these cars don't have lifters... the rocker arms ride directly on the cam.
