EA82 knocks when cold


Recommended Posts

Even when moderately cold, ie. low 30'sF

 

It is EA82 from 92 Loyale with around 100K miles. I am not the main driver, so I don't really know what's going on with it, if it was ran low on oil or coolant or whatnot.

 

It wasn't doing it last winter. Any ideas? I was told by someone that it is worn out and doesn't have much time left. Though I find it hard to believe at that mileage.

is it a knock or a ticking? I thought the same thing last year and then I came to the board and found out that EA82s valve lashers go out and they dont pump up so you hear a pretty loud ticking noise..

I thought my engine was going to go the first time I heard the noise.

 

Start the car, go out and listen and try to pinpoint a cylinder and area on the block/head/cam covers where the noise is coming from.

 

Does the noise go away after you warm the car up? What is the oil pressure at an idle before its warm and after its warm and whats the rpm when your driving?

 

I ran my car low on oil a few times and it got pretty noisy but after the next oil change it quieted down

Sounds like piston slap. Specially since it goes away after 15 minutes. Both my EA82 and ER27 both "knock" for the first 10-15 minutes too. What happens is the aluminum piston in the steel sleeve of the cylinder, will be smaller than when it is warm. So when it's cold the piston is basically banging around in the cylinder, as the engine warms up, the pistons expand, and it goes away. It'll be fine as long as you let the engine just idle untill warm. I wouldn't rev it at all till the noise stops.

Weird, the knock went away complete.

 

Now, however, it sounds like I have a miss, or something similar. Something clicks in the area of distributor as far as I can tell and each click corresponds to a exhaust sound. It is intermittent without a pattern, but rather constant.

 

That's the best I can describe it. The spark plugs and wires are from this summer.

 

 

 

The second issue I encountered today, I found out out that the upper radiator hose was leaking right where it joints the radiator! It was dripping rather heavily. I retightened it so that seems to be resolved temporarily.
