Knocking sound
Ok I have had this knocking sound in my engine since i bought my 93VE feb. of 2008 when I did an oil change and used thicker oil 10w-30 it went away for three months then came back. when i did an oil change again it only knocks when the car heats up. no technician seems to no what it is one said valves but why would the valves knock only when the car is hot. I'm thinkin lifters any ideas........... and what oil should I use and what oil stablizer product is the best for ex. Lucas, etc Thanx 4 help

I have a similar issue with My 93 VG. There is a clacking noise once its warmed up. It doesnt have anything to do with oil, I don't know whether its coming from the Harmonic Balancer/Crankshaft pulley, or from inside the timing belt cover. Ive had people look at it, some say its from the crank pulley, others say its the timing belt tensioner. I havent had the belt changed since I purchased it, But I have had the water Pump done. It had 176,000 miles when I bought it, it now has 211,000 miles and rides like a champ! Anyone have any suggestions??

Is it like a ticking sound....or a snappy sound - could it be an exhaust leak that is hard to hear where it's coming from? Maybe you could buy a little spray bottle from the dollar store, and mix in 1/4 parts dishwasher soap to water and spray the exhaust manifold flanges....I did it to mine and saw a nice bubble show....

No its not an exaust leak, I drove one before that had that ticking sound, so I know its not that. It seems to sound like a diesel engine once warmed up a little. The crank pulley vibrates a little as I look at it. Someone says its the timing belt tensioner, and I thought it was the water pump, SO i replaced it. It went away for a little while, then once the car was running like normal it came back. But what ill probaly do start the process of elimination. Ill get the Timing belt and tensioner changed, and then if that doesen't solve it, then I know its the crank pulley/ harmonic balancer.

sounds more like the second one.............. although they're the same............a guy commented on that about changing the solenoids does that make a difference

The procedure is detailed on craig braces webpage in the stickies..

the solenoids are not the issue, it is the VTC assemblies themselves (they are under the valve covers) that make the noise. The grounding just causes the solenoid to constantly be engaged and sending oil to the assemblies.

it's not a speed drop... it's a power drop. you lose top end power. so your car doesn't accelerate as fast as it did before in the higher RPMs. it's not like you're driving along and all the sudden the car slows down
